When I have talked about global warming with LDS folks one consistent response I have gotten has been that the Last Days are coming, so why worry about it? In fact, they think, maybe global warming is a sign of the last days. There’s also a great deal of skepticism about science in that same group of people. |
All I know is that it’s feeling like Spring here in NYC right now. I just hope it isn’t hotter/muggier in the summer. |
I think the last days are coming, so I’m not worried about it. |
Given the descriptions of the last days I read, simply saying “the last days are coming” seems to indicate we ought to fear more if we actually believe that. |
As a mormon scientist who has problems with the global warming debate I’m happy to illustrate some of the problems I have with Gore’s message. The chief one is that he persistently confounds “weather†with “climate.†Showing pictures of “extreme weather events†like tornadoes and claiming that they are the effects of global warming is in my mind (and I think in the minds of most people) sloppy and irresponsible science. As far as I know, even climatologists who are proponents of global warming won’t defend his claims he makes in this regard. Here in Europe they are convinced that the dry winter they are having in the Alps is the result of global warming. This sounds great until you consider the snow deluge in Colorado. This is the problem with the global warming debate right now. We credit every new high temperature while ignoring the lows. We pay attention to every fluctuation in weather while ignoring that it isn’t synonymous with climate. I personally do think that “greenhouse emissions†probably will have a deleterious effect on the environment. But when you consider that we currently are in the middle of warming trend that started four hundred years ago, it becomes almost impossible to determine the contribution from human sources. I mostly just get frustrated at the sloppy science and reporting that is used to justify the media hype. |
I do know some climatists who defend the relationship between more stormy weather in some locations and warming. While, for instance, the relationship between warming and hurricane strength isn’t completely established there are at least reasons to believe it. |
People shouldn’t confuse weather fluctuations with long term climate change. The International Panel on Climate Change estimates that the total average increase in surface temperature in the northern hemisphere over the entire 20th century was about 1 degree farenheit. |
Ed, I fully agree and the media in particular is bad about this. The media has the annoying habit of not only looking for sensationalism but tends to want anecdotal examples. They do more to mislead than any. However one also shouldn’t assume that the 1 degree change won’t bring into play much more major changes. i.e. the glaciers melting, ice sheets melting, etc. For instance I think the catastrophe in the Canadian north with respect to species there is pretty layable to global warming. |
danithew,
I heard. What was it 71 degrees in Central Park! Dang, we shouldn’t have left NYC! Clark,
Well, to clarify a little, the current phenomenon we are experiencing here in America is due to El Nino in the Pacific. This cyclical pattern tends to create wild weather out west (as noted in the Rockies and Seattle), and very mild winters in the northeast. Here in Pennsylvania, we’ve yet to have any snow fall on the ground, when, by this time we should normally have at least one foot of snow on the ground. |
herodotus,
I don’t know of any scientist who says that global warming means warming in every corner of the earth. Like I said in my previous comment, the weather in Colorado is due to El Nino, not necessarily to global warming. However, when a huge chunk of Arctic Ice breaks off from the whole, I do worry. |
Dan, I was more thinking of the response by individual Mormons. If you really believe that the Second Coming makes such questions moot it seems bad reasonings since it is entirely rational to fear the last days when the world goes to hell. I think we ought do all in our power to prevent or postpone such events. |
Why have Mormon leaders been so silent on the issue? Mostly because it’s a scientific/political problem and not something that has any direct bearing on the Church’s mission. True, there are moral implications, as you point out, but Church isn’t in the business of identifying and solving every social problem. Of course, that’s not to say that we shouldn’t be responsible stewards of the Earth. I think our beliefs should lead us to feel some personal responsibility for taking care of the earth. But I certainly don’t think that the Church is being negligent by not taking a stand on global warming. This is especially true given the fact that there is much uncertainty as to what the actual effects of global warming are/will be. In addition, eliminating or minimizing the human-caused component of climate change is not a task the Church is at all equipped to manage. It would take massive, world-wide changes in how humans live their lives. We’d have to do much more than buy hybrids and get smart thermostats. We’d all have to do things that actually hurt. Until we’re willing to do those things, the little gestures we make do little more than appease our own consciences. Not that that’s a bad thing. But we shouldn’t fool ourselves into believing that effective change will be painless. Why are so many Mormons not concerned about it? For the same reason, I’m sure, that so many other kinds of humans are not concerned about it. It’s a large, abstract problem with complicated causes, with complicated, painful solutions, and uncertain consequences. It doesn’t help that a lot of the hysteria is ridiculous. Michael Moore thinks we should be running for the hills and calling our congressman every time there is an unseasonably warm day. Every time there’s a hurricane you see some jackass on TV trying to score political points by blaming it on Republicans and/or capitalism. Morons on both sides make it hard to sort out what’s hysteria and what’s balanced information. Having Al Gore’s name attached to a supposedly informational documentary makes it suspect. I have no interest in An Inconvenient Truth because it’s clearly self-promotional and is pushing a political agenda. I’m interested in learning about climate change. I’m not interested in hearing what Al Gore or anybody else who has something to sell thinks about climate change. That goes for Republicans too. What should we as Mormons be doing in our personal lives to reduce our contribution to the problem? We should reduce our contribution to the problem. But nobody’s willing to do the really painful things because they don’t trust that anybody else is willing to do the really painful things. And they’re right. Their efforts will do nothing more than appease their own conscience. They won’t stop the unstoppable forces of human greed and selfishness. I think our best hope is that the consequences aren’t as bad as some people think they might be, or that the second coming happens before things get real bad. |
Paula/Annegb – that is my concern that Mormons think who cares the last days are here. Well there are issues with that thinking – 1) the last days are here could be 200 years in the future and we may have self-destructed as a race by then 2) as stewards of the earth do we want to give God back a destroyed earth? 3) It seems a bit arrogant to push the problem back to God. |
Clark, I agree. I believe we have a responsibility and stewardship over this planet, and we will be held accountable for how poorly we treat it. I was just clarifying about the recent weather phenomenon. There are still natural occurrences at play. El Nino shows up every seven years or so to wreak havoc in North America. |
Oh this one is just toooo easy. The answer is obvious and in spite of the fact that this topic gets talked to death a million times a day. How about these questions instead? Why didn’t everyone evacuate from new Orleans before Katrina in spite of all the warnings? Why didn’t the people of Pompeii decide that there were better places to be then at the foot of an active volcano? Why do people in California think its a good idea to live right alongside one of the most active faultlines in the world? Because people deep down don’t really believe that something will happen to them? I’ve been okay up until now, so why should I worry? I can’t control what’s going on around me, all I can do is control my direct circumstances and frankly I like my circumstances the way they are. These arguments have been around since cave man Ug decided it was a good idea to live at the base of a cliff. “No rocks fall on Ug straw house yet, so why should Ug worry?” In todays Caveman Gazette: Large rock fall on Ug house today. Ug inside chewing on Mammoth tusk when rock bigger then house fall directly on it. No more Ug. Services today when big yellow thing is in middle of the big blue thing. In other news, big ice mountain seem to be going away. Shaman all over say we in deep sabertooth poo. BTW this coming from a skeptic (though not the kind you’re thinking of). Global warming (and cooling) have been in constant effect since the earth was first formed. During the Jurassic period Carbon Dioxide levels were three times higher than they are now. So, the cold, dark reality of the matter is that in spite of what a person believes, that even if we instantaneously stopped all human activity on the planet right now that the planet would continue to get warmer. Then, when the next ice age hits, it would continue to get cooler. I don’t debate global warming. I debate that when it comes to things much larger than our pitiful selves, such as orbital motion of the planet, the Sun and other fun variables such as these play a much more fundamental role in what happens to our planet’s climate. Scientists like to think that we are the cause of all of it, because if we are not, then what’s going to happen will happen in spite of us. No one likes to believe they are that insignificant and even worse have no control whatsoever over their own fate. Nature will eventually repair itself. The planet will somehow survive. The only trick? We might not survive whatever “the fix” is (massive volcanic activity, a big ol’ comet/meteor hammering into the earth, a sunstorm big enough to destroy all communication forcing us back to the bronze age etc.) Only the Lord knows for sure. |
Yes, cew-smoke, that WAS easy. Such a clear and obvious explanation to such a seemingly complex problem. Thanks! Now if you could only convince all those stubborn scientists who rely on actual data to agree with your logic, we might be able to join hands and convince people that only the Lord knows if smoking is bad for you so you may as well keep on smoking. |
we wouldn’t want to have to consume less. it might be uncomfortable. |
Why are so many Mormons not concerned about it? I can’t speak for every Mormon, but the reason might be twofold. First There is the belief “that the earth will will be renewed and recieve its paradisical glory”, sounds like no matter what happes here or now that everything will be OK. Secondly, Mormons are just extra busy people with more meetings and social events than most people. If they do care it gets cast off aside for somebody else to worry about. I haven’t had the chnace to see the movie yet but I would like to. I believe that global warming is a naturally occurring event. It is cyclic. Global warming may be followed by global cooling and a next ice age. The problem is humans have increased the problem and screwed up the earths equilibrium. Will the earth be able to overcome the human footprint? Only time will tell, of course it may be too late for us… |
A problem is that if we are confronting a dire calamity, then little touches of conservation to reduce emissions a few percent here and a few more there are irrelevant. Nothing short of wholesale abolition of combustion will make a difference that matters. Take it back, Prometheus. |
Rusty, Did someone eat a bowl of sarcast-ios in sour milk this morning? In response to your fun-filled personal attack post, let me pose this to you. Why is Egpyt no longer the land of milk and honey? It stopped being so long before the industrial revolution. How about the rest of the cradle of civilization? Why is it a raging desert, where once it was considered the bread basket of the world? Why indeed were the CO2 levels 3x higher during the Jurassic period? Why have their been so many ice ages? Why did they end? The answer my friend, is blowing in the wind. Take a look at the work done by so many excellent Paleo-climatologists. The earth and its climate is cyclical. Always has been and always will be. I did say that I am not debating global warming. It definitely has gotten warmer. Just as it has many, many times in the ancient past. What I do debate is that what is coming is coming. No amount of crying or complaining will change that. What scientists need to concentrate on is not doing the thirty thousandth model of what might happen. They, along with engineers, agriculturists, political leaders, etc. need to start finding viable medical, social and economic changes that can be put in place to deal with things like Africa becoming one vast desert and the great mid-west bread basket moving smack dab in the middle of Canada. I can assure you (as any good scientist would agree) that when you start crying about the exhaust from cars which produce less than 10% of our CO2 output and you talk about reducing it by 15%, your sum is nada. You have accomplished nothing. So, if the future is inevitable (and it always is) then perhaps we should start finding ways to deal with the future. Even the most die-hard, humans are the ‘root of all things evil’, global alarmist will tell you that the current pattern would continue in spite of anything, no matter how drastic, we did as a species. At a minimum it would continue at its current rate for another 100+ years, and there are others who will tell you that it won’t end until the next ice age (because we are not indeed the primary variable to global warming). So, the answer is not how do we stop global warming. That is a pathetic and vain attempt at jousting with windmills. The answer is what are we going to do about the aftermath. |
Tom – good answers. I think you have some interesting answers to the questions. I would rather see the Church spend money on promoting President Kimballs mantra of recylcing than fighting against gay marriage for example – the Church can and should be more involved in issues like these. All – I am amazed at the number of us who think God can magically fix the damage we do. God is not a magician and helping the earth receive its pardisical glory may take longer than 1000 years if we continue screwing it up. CEW-SMOKE is right, the earth will survive and eventually repair itself but we may not be around. |
cew-smoke – lets assume that there is nothing to be done unless drastic measures occur today. Ok – where are the drastic measures? What are we doing to prepare? Nothing. We don’t have any alternatives for oil when it runs out and, despite GWs insistence we will have it forever, we will run out of the stuff. So what do you suggest we do? |
#5 Herodotus – You say it is impossible to quantify the human impact – perhaps it is, but the question is not whether we are having an impact, but what can we or should we as Mormons do about it? |
I tend to agree John although I think that significant changes can really reduce the catastrophe. But yes, I think the measures that are politically called “extreme” are themselves so small as to achieve very little. Given human nature unfortunately I think the catastrophes of global warming are inevitable. |
I agree with John that it will be hard, probably impossible, to meaningfully reduce emissions. The fact is that there is a lot of oil, gas, and coal, and somebody is going to want to burn it…if not us, then the Chinese, Indians, Indonesians, etc. We can’t really stop them, and even if we could, it wouldn’t be fair. On the other hand, I think it is quite possible that we could find other technological solutions to reduce warming, perhaps by incresing the albedo of the earth or atmosphere somehow. |
People will only do something to help the environment if it makes sense economically. About seven years ago the NY Times ran a article about how it was cheaper to throw garbage away instead of recycling. Some people will help the earth by not driving so much. It’s not because they care but because gas is too expensive. |
Clark/Ed/Jared – a little bit pessimistic, but probably close to the truth. It does all come down to $$$. I wonder if the next war will be with the Chinese over access to oil… |
Devyn S. Excellent question. However, I will be the first person to tell you that I simply don’t know the answer. What do we do? You generally fall in one of three camps in this argument. Either you don’t think global warming is happening, you do and you think it is a result of human involvement, or you are like me and think that perhaps we do excaserbate the situation, but that the warming trend is an inevitable cycle. Here are some simplified descriptions. Group 1 – Do nothing ’cause there ain’t nothing to do. Again, as the third kind of global warming group I’m not convince there is much we can do to stop it. I could offer some ideas appropriate for Group 2, but the reality of the matter is that whether it be human or external variables causing the warming trend, no small scale fix will help. If you think that you try and tell a farmer in Guatemala that he should stop burning down the rain forest for his farm land and he has to choose between what you’re telling him and his family starving. The obvious reply will be given. I do have a bit of good (read: sarcastic) news from my limited perspective. Humans will do what they have to for their survival. If we run out of oil we’ll make substitutes. Go down to the Cayman Islands and they don’t have enough fresh water to support themselves. So, in response they built some of the world’s most advanced de-salinization plants. If the Colorado aquifer runs dry and the rivers can’t supply the means, don’t think for a moment we won’t do the same. If we can no longer supply enough coal and oil to heat our houses and power our TVs, we’ll go nuclear in two shakes of lamb’s tail. Folks would rather risk cancer than miss the season premiere of Lost or Desperate Housewives. The good news is if we went 100% nuclear (except for all the nuclear waste we sludged the world with) our CO2 levels would drop dramatically. Yeah, it kind of sucks. We’re kind of a lame species that way. However, in the end we’ll do WHATEVER is necessary to either A. maintain our way of life or B. die trying. |
I would support more power from a nuclear source. We’ve put dams on to many rivers and now the fish suffer. |
“the Last Days are coming, so why worry about it?” In other words – “eat drink and be merry. For tommorrow we die.” |
herodotus, I’m not saying I disagree that Gore uses hype to push his message. But you’d be better served to leave Colorado out of this. It proves nothing. Colorado typically gets its heaviest snowfall in early or late winter. To get this kind of snow at this time of year is highly unusual. In fact, it’s been almost 100 years since Colorado had this kind of snowfall in December-January. The cause of the storm climatologists are pointing to are this year’s El Nino patterns. Climatologists actually point to the winter storms in Colorado as mildly corroborating evidence of global warming. |
Devyn S. Historical Point of Interest The Vietnamese, Chinese, Phillippines, Taiwan, and Indonesia have all been on the verge of open hostilities over the Spraytl island chain throughout the 1990s. Vietnam and China have actually had pitched naval battles over the issue – repeatedly. The Spraytls are said to sit over sizeable undersea oil reserves. Japan, Taiwan, and China also posture against each other over another island chain farther north for the same reason. China has recently been dumping unprecedented amounts of foreign aid and investment into Africa as well. They’re trying to secure dibs on Africa’s natural resources. It’s quite possible that they’ll manage to lock the US out of that strategic energy source. Truth is, I don’t need the global warming concept in order to get worried about overuse of fossil fuels. Geostrategic concerns of energy supply make me much more worried, to be honest. It’s more likely that we’ll kill people off in a few more devastating wars over strategic energy reserves before global warming gets any of us. |
“I would hate to have questions around my destruction of the planet come up at the judgement – I have enough other issues to deal with there.” I think this is why the church per se doesn’t make a big deal about it, although we’ve had enrichment meetings about recycling, etc. through the years. The church’s mission has higher priorities. Our family has a hybrid car, and we try to minimize our car trips around town. I bicycle to work and lots of errands. We have the smallest garbage container for our trash collection, because we recycle and compost and don’t use a lot of prepared foods. We also used cloth diapers. It’s not much, but if everyone did such things, it might make a difference. A few times when I’ve rented a car for work, the agency stuck me with a SUV as that’s all was available, and I was astonished at how much gas those things burned through. Shudder. I don’t want to live like that. |

devyn,
Hmmm, a couple of things to note. 1. If there is a war with China, it won’t be instigated by China, but by America. China is too smart to start a war against America. 2. This should highlight why we need to break our addiction to oil. MPG should be at like 100 mpg! We shouldn’t be happy with only 30 mpg as acceptable. |
CEW-Smoke #28 – I think your response makes a lot of sense. I agree with your assertion that people would much rather risk dying of something horrible than miss the latest American Idol. I like the three groups. I see three types of Mormons in those groups |
Naismith #34 – I agree that if collectively, 300 Million people did something it would have an appreciable impact and we could at least hold off the inevitable until we found better sources of fuel. Kudos to you and your family! Clark #35 – while I know big families might require big cars, Toyota is coming out with a hybrid Sienna. Let me guess though – you live in Capitalism USA or Utah :) Dan #36 – I think that once China becomes larger eonomically than the US then they could do whatever they want and if we have something they want they will take it. I agree completely on the gas mileage – it is pathetic – we get more efficient cars then put more weight in them to mitigate any gas mileage benefits… |
And yet, I’m still not worried, because it’s the second coming. :) |
Devyn,
Maybe. I still don’t see any indication that there will be a full scale war with China, instigated by China. They have no reason, even economic. They’re gobbling up Africa with investments, they are buying American debt, etc. In the end China will inevitably be the world’s most powerful nation. It is not a matter of if, but when. They just simply have too many people for America to compete. A fully developed China should be our best ally, not an enemy. I think Americans need to stop looking for an enemy in China. |
Critics of religion often separate religious believers into two camps: moderates and extremists. Extremists are to be feared for the lengths they’ll go to to defend or promote their beliefs (i.e. war, terrorism, etc.); Moderates are relatively harmless because they don’t force their beliefs on others, or so the thinking goes. These I’m-not-worried-because-of-the-Second-Coming answers make me wonder if there is any difference between Moderates and Extremists when it comes to endangering the world? If the latter doesn’t nuke it into oblivion, the former will passively consume it into oblivion. Furthermore, every generation since the time have Christ has been sure the Second Coming would happen in their generation. The first five Mormon prophets were pretty certain Christ would return in their lifetimes. Meanwhile, the years keep ticking by. Those whose confidence that such an event is nigh must have pretty sound evidence, I assume? If so, please share the good news with the rest of us so we can all go out and buy Hummers. So, just because you believe the Second Coming is right around the corner does not mean the rest of us who share this planet hold the same belief. Lets work together to keep this beautiful planet green and blue. Wouldn’t God want it that way? |
Dan #40 – I am not trying to find an enemy in China, but world history has demonstrated that once you have 2 superpowers the competition begins and inevitably ends in a war. So while I would love to coexist peacefully with China, it would not surprise me if we hit heads at some point in the future. I hope you are right though. Matt #41 – Beautiful comment – I really like the insight into the two groups that can prove equally destructive to mankind. Thanks for that – I think it is a great summary of how I feel. |
For those of you looking for scriptural ammunition against the eat, drink, and be merry crowd, consider the following: D&C 51:17 And the hour and the day is not given unto them, wherefore let them act upon this land as for years, and this shall turn unto them for their good. |
Just checking back on this thread. Several people replied to my comment and I don’t really know how to begin responding. Let me start by recalling that the lead post here from a “mormon scientist†essentially asks the question of how anyone could doubt the evidence for global warming. Let me add a few comments before I reply to some specific comments. In the 20th century most warming occurred before 1940, when production of CO2 was low. From 1940 to 1980, global temperatures went down while human addition of CO2 increased most dramatically. This was so significant that the news media ran stories like this, “There are ominous signs that the Earth’s weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production — with serious implications for just about every nation on Earth.†That quote is from Newsweek. It was talking about the ***ice age*** they feared was coming based on the temperature decline from 1940 to 1980. Similar stories were carried by all the major outlets including the New York Times and Time magazine. Global temperatures increased from the 1980s into the 1990s and then since 1998 global temperatures have declined while human production of CO2 continues to increase. I don’t believe that any of this this implies that global warming can’t or won’t happen as much to point out what a mess the data sets are on which we are asked to base policy. Now let’s consider the cost of intervention. The Stern Report argued that the emissions cuts necessary to stave off disaster would cost about 1 percent of global GDP yearly. This isn’t what is required to stop global warming, just accommodate it. Now, 1% of the world’s GDP may not sound like much, but it is. It’s huge. These are the chips we are playing with when policymakers show us a picture of a hurricane and tell us that it is due to global warming. This is why I give people the “blank stares†the lead poster asks about when global warming is referenced. One or two specific responses: Dan says, Calving is what happens to waterborne ice. In Antarctica snowfall has been stable for the last 30 years and the continent is gaining ice. Seth says, I’ll tell you what Seth. I’ll “leave Colorado out of it†if you’ll stop confounding weather with climate. This is why I brought Colorado “into it.†A single weather event isn’t evidence for climate change despite your assertion about climatologists considering snow in Colorado to be evidence for global warming. Which way do you want to have it? If you are willing to admit that El Nino may be responsible for what is happening in Colorado, perhaps you’d be prepared to concede that it might have other effects – like unseasonably high winter temperatures across the rest of the Midwest. I’m feeling a little overdosed on the bloggernacle echo-chamber lately so I apologize if my tone is gruff. I won’t comment in this thread again. |
I think good people living decent lives are relatively not messing up the environment and this is just one more issue that polarizes and brings contention and God would rather have us concentrate on more important things. I don’t think the planet is in all that bad a shape in the first place. |
I think Al Gore is a putz. |
what’s that word that’s used when people try to justify there actions, however lame they may be by saying it’s not so bad… i don’t… like when your sister is dating a jackass but refuses to see how toxic (no pun) the relationship is? hmmm, it’s right there |
their actions. |
#41 what do you consider bad shape? seriously? |
Unfortunately, Anne’s twin response in #45 and #46 encapsulates all too well the mindset of a huge percentage of Christian America: one part head-in-the-sand denial (#45) and one part prejudicial bias (#46). One unfortunate downside to the obedience/faithful mindset bred by authoritative religions is the over-reliance of members on leaders to do the thinking for them, at least on the big issues. The purpose of life, the nature of God, the boundaries of morality, etc… we are not to figure these things out on our own, but accept what our leaders tell us about them. When acceptance appears to bear fruit, the dye is cast and future behavior is set. We rely on our leaders to tell us what Anne’s “important things†are. So, for Mormons, the important things we are told to worry about are Gay Marriage, R-rated Movies, immodest dress, multiple piercings, etc. For Evangelicals it is Gay Marriage, Evolution taught in classrooms, the evils of Harry Potter, etc. If something as monumental as Global Warming is a serious threat, God would tell Pres. Hinckley who would then tell us, or so the thinking goes. Because the Church is silent on Global Warming, an expression of fear or concern on the matter is almost like showing a lack of faith in our leaders. But make no mistake, if President Hinckley were to stand up in April and use his closing talk to address the reality and dangers of Global Warming, Mormons would be singing an entirely new tune, thus confirming my point. |
So what if Al Gore is a putz? Are Al Gore and Global Warming synonymous? Can Al Gore be a putz AND Global Warming still be credible? FWIW, I liked “An Inconvenient Truth,†but would have strongly preferred another person as the figurehead and spokesperson. The documentary should be about the issue, not the person. It was obvious that too many people would discount both the movie and the issue as soon as they saw the messenger. It’s an age old phenomenon… witness the multitudes who dismissed the BOM and the gospel as soon as they learned it came from Joseph Smith. |
My head isn’t in the sand, I just don’t think the problem is as bad as we make it out to be. I don’t think it’s a monumental problem at all. I think there are so many other problems to worry about first that it’s a non issue. You’re right, it doesn’t matter if he’s a putz or not. And make no mistake, you are absolutely right, at least as far as I’m concerned. If the prophet said this was a priority, I would haul myself off my behind and start recycling and Bill would be driving a much smaller vehicle. You bet, if the prophet said it, I’d do it. I still think God has higher priorities or the prophet would have said it. |
annegband what are the “important things”? funding for education is important health care for everyone is important good public transit is important |
so back to the point… annegb, look out the window, that crap floating around in the air, you know the stuff that makes it so we can’t see the Wasatch mountains, thats the earth saying, “i ain’t doing to well and i need you people to stop doing what your doing because your killing me” |
Well Anne, at least you are honest and consistent. I hope for the earth’s sake that Pres Hinckley will make a statement someday so you and Bill and everybody else will jump on the bandwagon. I’m not holding my breath though. The Church is usually behind the curve on these kinds of issues, waiting until the rest of the world has figured it out before officially acknowledging reality. |
I am a meteorologist. That is what I do. Mainly weather, but some climate (they are too very different things). I have worked for an organization that studies CO2 (www.co2science.org) and agree with them. They take the 70 year temperature records from different locations and they have COOLED (that’s right COOLED) on average of a degree over that time frame. That is science to me. Not speculation about what is causing this or that. Cold, hard facts. Global warming makes hurricanes stronger?? More of them?? What happened this year then?? We honestly don’t know enough about the earth to say whether it’s ‘global warming’ or just a natural cycle. The media is just a tad too gun ho for my liking. |
Oh, and all that work there are members…from my home ward. |
Amy, I don’t know of anyone who claims global warming means those words literally, that EVERY location in the world is heating up. Those who do know the science know that a warming trend around the world affects each particular area differently. Because of this or that, there are actually areas of the world that cool rather than heat up. |
These are site from across the US. Data that widespread is hard to ignore…especially from a country that puts out some much CO2. I just think people are making too much out of something we really know very little about. Very little. |
Amy, could you share some of this data with us? |
Amy, See I see what you are writing, but then I see a report like this, which shows that 2006 was the hottest year on record in the United States. Furthermore, it caps a nine year rise in temperatures in the United States.
So it would be nice to compare this to whatever evidence you have of cooling going on in the United States. |
The data Amy referes to can be found here: http://www.ncdc.noaa.gov/oa/climate/research/ushcn/ushcn.html The pattern from the US weather stations appears to show a modest warming from about 1900-1930, a very modest cooling from about 1930-1970, and a warming from 1970-2000. So Amy is right that the instrumental record shows little or no warming between 1930 and 2000, although picking 1930 as a starting date seems like cherry picking to me. Also, the warming trend appears to be continuing since 2000, with some of the warmest years on record. Remember that the IPCC itself only estimates about a 1 degree F average increase in the northern hemisphere over the entire 20th century, which seems pretty consistent with the data above. I’m not sure what the people at http://www.co2science.org are actually trying to claim. Amy? |
Well, let’s add more fun facts to the list. I just finished reading a story today that said Eastern Europe is experiencing one of the coldest winters on record. So, we can point out little things like that out all day. They don’t amount to much, because we don’t really care what happens in a single year (or even over a few years). We care what is happening over a much longer scale of time. Why do I think the world is slowly getting warmer (cyclically, not human global warmingly)? Goes back to my earlier questions. Why is Egpyt not the land of milk and honey anymore? Why is the Tigress and the Euphrates not a “bread basket” anymore? Why are the deserts growing at such an alarming rate in Africa. One year a village is in a field of wild grass, the next it is a desert death trap. These trends started long, long before human intervention. What does that mean? It means that the climate changes and we must adapt. We have been doing that as a species for many, many thousands of years. The good ol’ USA used to be glacier central. Where did they go? Well, they melted the last time we had “global warming”. Go have a long talk with your neighborhood paleo-climatologist. It might open your mind to some new ideas and concepts. Absolutely fascinating stuff. |
Google the terms ExxonMobil and co2science.org … |
Or check out the Sarah Scaife Foundation’s 2003 Report and note that the Center for the Study of Carbon Dioxide and Global Change is listed as a recipient. |
Or consider this Wiki entry: excerpt below, emphasis added Some organizations … formed to promote … [AGW] opponents’ views: Cooler Heads Coalition. Information Council on the Environment (defunct): Michaels, Balling and Idso all lent their names in 1991 to the scientific advisory panel of the Information Council on the Environment (ICE), an energy industry public relations group. Center for the Study of Carbon Dioxide and Global Change. Many of these opponents to the anthropogenic, global-warming theory have links to the fossil- fuels industry. For example, Patrick J. Michaels and Frederick Seitz have both been linked to the George C. Marshall Institute–Michaels as a “visiting scientist” and Seitz as “Chairman Emeritus.”. The Institute has received numerous large grants from ExxonMobil, and from petroleum-related organizations such as the Sarah Scaife Foundation and the Carthage Foundation. Similarly, the Competitive Enterprise Institute has received several large grants from the Charles G. Koch Charitable Foundation, the Sarah Scaife Foundation, and from ExxonMobil. The CEI website lists both S. Fred Singer and Robert Balling as “experts,” while Ross McKitrick headed up a CEI project called the Cooler Heads Coalition. Many observers are critical of these connections between global-warming contrarians, and the petroleum- and coal-industries; such connections suggest a conflict of interest, if not outright corruption, since many policies which might be used to combat human-caused global warming might adversely affect the profits of these corporations. |
Oops, how about this Wiki entry |
ahh, finally some science and facts with actual references. I think that the actual data is compelling that something is occurring and that the earth is warming. We also have a dramatic increase in CO2 levels brought on, at least partially, by humans. Ok, so something is happening and I believe we should care. I think it is wrong to wait to be told what to think is important by the prophet – we are here to THINK for ourselves and we should THINK. Just because the prophet does not say human pollution is a problem does not mean it is not a problem. We are taught to think and act for ourselves so lets start doing it! |
Statistics can be made to say different things depending on the period of time you choose to observe and many other variables. It’s not really disputed in the scientific community whether global warming is actually happening. The mere fact that Republican congressmen have managed to drag up a few fringe scientists denying the overall trend doesn’t say much. In all fairness though, scientists freely admit that very few of them are sure what actual global effects global warming will have. For instance, few are willing to link blizzards in Colorado, hurricanes in Louisianna, or tornadoes who knows where else – with global warming per se. Like I said, while I accept the general idea of global warming, and that it IS human-caused, I’m not too interested in it. I find the problems of energy scarcity and security of world energy supply to be more pressing. |
From CNN today – 2006 warmest on record Seems like hard data to me that something is happening… Seth R – I think that the energy issue is very related. If we find better fuel sources that burn cleaner we get two for one. We save the planet as well as our country… |
I realize I am late to this discussion, but nobody has mentioned my viewpoint, so for what it’s worth, I’ll chime in. I have believed for years that the Church has taken a strong position on our responsibilities as stewards of the earth, but has done so in a way too subtle for many to catch it. In over 100 buildings scattered throughout the world, there is a Church-produced film that thousands of recommend-holding members watch on a regular basis. An introduction to that film tells members to consider themselves as if they were actually playing one of the parts of the main players. The film then shows us, as one of the main players, agreeing that the world on which we live is “glorious and beautiful.” Shortly after this declaration, we move in to this glorious and beautiful world with our husband or wife, and are told that our main responsibilty with regard to it is to “till and take care of it.” I haven’t seen “An Inconvenient Truth” because I can’t stand Mr Gore. No matter how hard he tries, he comes off as a smug, sanctimonious hypocrite. But I have seen, many times, a movie where I am told to take care of the glorious and beautiful world that God personally created as my home. That is why I care. |
CS ERIC #71 Your sentiments were well expressed and I agree with everything you’ve said. I think that the “foolish traditions of our forefathers†often get in the way of the pure gospel. |
#62: As I understand it, the Center is stating that all the talk of global warming may be unfounded. I haven’t worked there is years, so I may be off the mark. They review tons of paper that show how much vegetation loves CO2 and things along those lines. The reason they went back so far is that if it truly is global warming – it would take many, many years for it to truly take effect. I should have stated early, I do not claim to be proficient in this field. Far from it. But, many scientists will say that we just don’t know enough. 2006 is the warmest on record — that is a fact. I don’t deny that. But climate deals with long, long term data – not just one year. 9 years could be the start of a trend, it’s true, but we just don’t know for sure. And I, personally, will not get all hot and bothered about a “maybe”. Not worth my time right now. #66: They work on grants. That how they get $$. Who do you think would like what they’re saying?? I know for a fact that they aren’t saying it for the $$ – the money is coming because of what they are saying. They have not been bought. They are honorable members in good standing. Great people. |
Amy, I have nothing against reasoned arguments against global warming theories, but it doesn’t seem to me that the people at http://www.co2science.org are arguing in good faith. They seem to be presenting the lack of warming in the from 1930-2000 as a “gotcha,” as if global warming proponents have just ignored this data or don’t know about it or are trying to cover it up. In fact, as far as I can tell, the instrumental record they point to does not contradict at all what the IPCC has claimed about climate history over the last century. Good faith argument requires that we attempt to clarify what areas of agreement and disagreement are. (Of course global warming proponents are also often guilty of arguing in bad faith, atticking people’s personal motives, over-simplifiying, exagerating, etc.) |
As to the notion that “the money is coming because of what they are saying”, I would apply Tom’s standard from above: “I’m not interested in hearing what Al Gore or anybody else who has something to sell thinks about climate change.” And, yes, I’m aware that all research is funded in one way or another. I agree with Ed’s view that there are folks arguing in bad faith on all sides of this issue. I’m not one to imagine corporate boogeymen as the source of our woes. On the contrary, I feel dismayed, not delighted, at any apparent evidence of US companies adopting losing strategies. I have no strong opinion or sense of where the truth lies in the global warming debate, but it seems painfully obvious to me that US interests would be much better served if our companies would seriously fund green technology development rather than spending on these old-school PR efforts. We can’t export PR, but there’s a huge market opening up for green tech, and I’d hate to see our companies miss out in the same way our auto industry has so far, by assuming they’d always be able to manage US consumer demand through PR operations rather than stepping up innovation. No doubt the US continues to innovate in impressive ways, I’m absolutely not dissing the US, but if we are not open to the possibility that our all-too-human industrial leadership is capable of strategic blunders, we have no chance of ever being part of any possible solution. |
Chino, I feel exactly the same way. You wouldn’t believe the technology that has been developed that never seems to make it to the consumer…solar panels that are essentially like stickers for your roof, battery-powered engines that stay charged for hundreds of miles…its amazing. You should all watch Who Killed the Electric Car. I personally wish the price of gas would go so high that it would force us in this country to drive less and find alternatives means of transportation. I think if members who could see more first hand the effects on the environment around the world they would care more…its easy to drive your Pathfinder when you don’t have to live next to the refiniries in Nigeria that are killing a generation of children. Or heck, even if you live in Pearland, TX you might reconsider when you see the nasty air, and those plants have to follow government restrictions. But, people can’t seem to see past their small little lives. My parents, with their two V8 SUV’s, told me that the world won’t go to hell until their dead, so who cares. Your posterity thanks you. I mean, even if the Second Coming is going to happen, say within a hundred years…we still have to live in this mess, and people are dying because of our lifestyle of our over-consumption. Surely we are accountable for that. The LA Times did an awesome two part article recently, investigating the Bill and Melinda Gates foundation, but it was a great insight into how pollution is negativly affecting millions around the world, mostly the poorest. |
Veritas, I hear you, I live in Taiwan, have spent the last 12 years living/working around Asia, mostly for American- and Taiwan-owned outfits. I see folks up above talking as if there is some kind of inevitable conflagration with China looming. Bummer, what a bunch of fatalists. I always pegged Americans for being practical types who could take lemons and make lemonade, not the types to shrug their shoulders and assert there’s nothing to be done, the die is cast, waah waah … I particularly pegged Mormons as being not only practical but fairly astute at business to boot … in any case, I’d suggest it’s not all gloom and doom, but frankly we’ve been poorly served by our recent political and industrial leadership … it’s been all fear, all the time, for way too long, until now even the Mormons have started talking like they’re hapless subjects of some twilight militaristic empire lumbering towards an uncertain future, crikey, half the world wants to buy an iPod and the other half already owns one, goodness, how much more of an advantage do you need before you start looking outward with a little less trepidation … anyway, as far as I can tell, the resource base simply does not allow for China and India to reach full development using current technology, there’s simply not enough steel and oil to get them from where they are now to a US standard of living unless we start getting creative along the way. Not to mention, China is becoming so polluted so quickly that they’re going to start seeing that impact on their GDP, and when that starts happening, you know there are going to be some huge contracts signed to bring world-class green technology to the country so as to keep growth on track … Taiwan is already ramping up its solar capabilities in the expectation of supplying the Chinese (and world) market … man, it’d just be nice to see a little more enthusiasm for the future from the US side … as China, India and others develop, it’s going to create new markets for our products and services, but we need to be vigilant about keeping up with where the world’s headed if we’re going to maximize these new opportunities … If Americans, by clamoring for and adopting green tech in their own lives, thereby demonstrate to US companies that there is a home-grown domestic demand for greater fuel efficiency, lower emissions, etc., etc., this will in turn help our US companies to make better choices and consequently improve their global sales potential … especially for those of us who live in the extremely crowded bits of the planet, we’re going to desperately need green vehicles, green homes and offices, and I expect we’d be quite happy to look to the US to lead the way, but if you end up having nothing we want to buy, I hope it’s not down to your own domestic consumers being such exceptionalists that they can’t even see where their own benefit lies in adopting new and greener technologies … |
Chino, I agree that there’s no need to write an obituary for American hegemony just yet. I believe one comment mentioned that China ABSOLUTELY WOULD overtake the US in world power over the next few decades. Hogwash. I’m not saying it’s impossible, but to call it a done deal already is extremely premature. The whole population argument doesn’t hold any water either. “Gadzooks! They’ve got more people than we do!” Yeah? So what? Notice that no one makes the same arguments about India (and they’ll have even more people than China shortly). China is an emergent “great power.” Like Russia, India, Brazil, and Germany and the like. China is NOT an emerging superpower. We’re not even close to that stage yet. There is still only one superpower: the US. But that doesn’t mean we can ignore the runners-up. There are still plenty of challenges to world security posed by these “great powers” and things do need to be finessed to keep them from causing trouble. |
Chino and Veritas – great points. I think that it can and should start with consumers who demand green and clean technology now or we are screwed in the future – whether global warming, pollution or something else it is not a pretty picture. Seth R – glad you drink the Republican Kool-Aid, but the reality is that at current economic growth China will surpass the US in GDP in 20 years or less. India could as well as some point. Not to call them superpowers or emergent is silly and inward looking. We must prepare now and determine how we are going to address it. If the US is such a superpower we are sure not showing it in our current foreign debacles… |
Can the name-calling Devyn. It was uncalled for. GDP is just one indicator of national wealth and power. The GDP of a high-population nation can be very high indeed and still leave its citizens dirt-poor. China has absolutely no navy and I’m not even sure that their nuclear arsenal could reliably attack the Western Hemisphere. In theory, yes it could – in theory. Their army is large manpower-wise, but in reality it’s not much stronger than Saddam’s Iraqi army was in 1990. Same outdated Communist equipment. China doesn’t even have the capability to invade Taiwan right now. Their troops are all stuck on the ground. What are they going to do? The million-man-swim? Right now, Japan’s military completely outclasses China’s and that’s just a “self-defense force” built on less than 1% of Japan’s GDP! The Chinese are very worried about Japan, and with good reason. China would lose a conventional air or naval battle with Japan if it were fought today. Besides, indicators are that China’s rapid economic growth is out of control and could tank its economy in the next ten years. Not to mention some very troubling demographic trends that point to societal and political instability. China’s biggest asset is its ability to bluff and intimidate. It far outweighs any other assets they have. I’m not trying to minimize China or write it off. China as a mere “great power” is troublesome enough to US interests and deserves to be taken seriously. China is also a serious threat to its neighbors. Furthermore, if US global power and influence continues to diminish, China will certainly grow stronger by comparison. China is a challenger, no doubt. But to say that China has the kind of power projection capabilities the US does around the world doesn’t mesh with current reality. It’s no superpower and isn’t really expected to be any time soon. |
Conservative Christians interpret the Book of Revelation literally, as a prophecy: “after the last tree is felled, Christ will come … ” To Christians, as written in their statements of faith, the Bible is the inerrent word of God. We realize through the JST, revelation and common sense that there are likely errors that came about in translation. You can actually follow US policy making on environmental issues by reading the views of Dominionists that counsel Pres. Bush (including Robertson, Falwell, Buchannan, Colson and Dobson). Compassionate conservatives like Osteen, Hunter and Warren ARE concerned about our world and have shifted their focus to environmentalism and poverty. |
Seth R – I was not name calling, but sorry if you felt like I was. I was merely stating what I thought of the idea that China was not a superpower. I actually think we agree that they are an emerging superpower, you think it will take longer to get there than I do. Either way, they and/or others will get there and then the US will have to change some things… I hope you are right and it won’t be for a long time before China is a superpower. By the way, I read in the WSJ that they are building an aircraft carrier now… |
Heh. Interesting move for them. |
I also read in the WSJ that China has purchased a significant amount of arms from Russia. I guess even if you have 5 M men with sub par weapons they can do a lot of damage against our much smaller military with great weapons… |
i watched an INCONVENIENT TRUTH last night. i don’t know Al Gore, just that he was VP when i was in HS and that he lost to bush. so, i thought the movie was brilliant. i thought he presented the facts very clearly and for anyone to understand. (and i do know how stats can be manipulated, but when you go back 650,000 years, i don’t know how you can mess with that) i’ve heard a bit about him in this thread, as if he has no business talking about global warming, and i’ve heard much about weather vs. climate. 1. why do some call him names and for that reason not see the movie? 2. i didn’t think he was focused on “weather” patterns as much as some have mentioned. so to those critics, have you seen the movie? if so, have you looked into those “things” that you think are manipulated? |

nice work on my part eh? the computer wins! |
Devyn, You’re making a big assumption here. You’re assuming that we’d ever actually fight those 5 M men if we were to declare war on them. The only way that would happen is if we actually invaded mainland China. Which I don’t see us doing. No any war between the US and China will involve naval battles, airstrikes, with the threat of nuclear unpleasantries hanging over the whole thing. I mean, that’s plenty of reason to avoid a war with China like the plague, but the truth is that China’s well-populated army is simply unusable in a conflict with the US, Japan, or even Taiwan really. |
mfranti – Glad you liked the movie – I think many people just don’t like Big Al and so dismiss the movie. However, he does a pretty credible job of explaining the science in lay terms. While people can argue about his conclusions about the effects of the CO2 buildup the data was pretty sound. I am sure others on this post have other thoughts, but overall I liked it, but I like Big Al and I am also a pro-environment type… |
Seth R – perhaps we would never invade mainland China, but who would have thought we would have invaded Iraq and Afghanistan. I could see unpleasantries starting over either Taiwan or North Korea. But, like you, I see it as unlikely and hope it never happens… Heck, where would all of us get our cheap clothes and electronics. |
devyn, “Heck, where would all of us get our cheap clothes and electronics” read between the lines, eh? you speak the truth. |
mfranti – unfortunately, China is our largest trade partner and we have such a huge trade imbalance with them at this point as all we do is buy from them and ship very little back. Someday it will shift again and some other country will be the source of our cheap stuff. Just as it moved from South Korea and Taiwan to China. The bigger fear is that all we do is continue to consume and destroy the environment in the process… |
“The bigger fear is that all we do is continue to consume and destroy the environment in the process…” i keep seeing the scale, gold on one side, earth on the other… i think i said something at the beginning of this thread about not wanting to have to CONSUME less, it might be uncomfortable. i notice no takers(from the other side) on my questions. |
Your scale is pretty accurate unfortunately. As mentioned by others here, once oil/gas get expensive enough then people will begin to care. You saw a little of it when gas went over $3/gallon – we need a lot more of that… |
Well, maybe we can start terraforming Mars or something by the time Earth’s truly finished eh? |
that’s right throw up your hands! |
Bush is all over the Mars thing – just a bit expensive at $1T, but would be pretty cool to send people there. Of course, $1T could be used in a lot better ways here on earth. That would certainly create some cleaner technologies… |
Exxon cuts ties to global warming skeptics “The fact that Exxon is [now] trying to debate solutions, instead of whether climate change even exists, represents an important shift†… |
Chino Blanco – thanks I saw that in the Wall Street Journal. Guess maybe Exxon is going to start playing the game like BP does – at least talk the green talk… |
Incidentally, try Googling the phrase “Axis of Oil” sometime. Cute title. Interesting links. |
Thanks Seth – some interesting articles with some frightening statistics and predictions – China, India and Russia as the axis of oil. The next 20-30 years should be very interesting on the global stage… |
Saw the movie last night. I thought it was well presented. He did not seem irrational or too extreme. I think that this movie could have the same effect as the book “Silent Spring” by Rachel Carson did several decades ago. The environmental movement might have a new surge. |
Jared – I agree – regardless of what one might think of Al Gore, he is doing a good job of bringing this to the public’s attention. It is also something he has been doing for many years. Hopefully, it will give a new life to the environmental movement |
I am interested in what kind of scientist have been making claims on this forum. I am actually an engineer with a background in math and physics. Currently I am working in automation and robotics with a specialty in artificial intelligence. About 25 years ago I was involved in studies for the government concerning magnetic variations throughout the world. Without going into all the details there are electrical currents that flow through the crust of the earth (like rivers) that create magnetic fields. These currents are caused by nuclear activity on the sun and increase as activity on the sun increases. The sun goes through regular cycles and for the past 100 years there has been cycles of increased activity – meaning the sun is in a cycle of getting hotter. It should not surprise anyone that is capable of real scientific research that when the sun gets hotter so does our planet earth. Yes, there is global warming but it is not from greenhouse gases. Greenhouse gasses are a misuse of terms and in reality there is no such thing. I have not seen a single scientific study that demonstrates the so called non-thermal conductivity of any of the gases listed as greenhouse gasses as compared to the other gasses that comprise our atmosphere. There are a number of claims of such but they each quote each other and reference no real actual studies. The claims about carbon monoxide as harmful to the environment have long been proven junk science because carbon monoxide becomes carbon dioxide when introduced to plants performing photosynthesis which gives of oxygen. And carbon dioxide is necessary for plants to survive and the more of it there is the better plants do – which means the better crops will do and the better we will be able to feed the hungry. A few years back there was a big to do over chlorofluorocarbons or CFCs blowing holes in the ozone, in particular Freon – which was anything but true. The truth is that chlorofluorocarbons do destroy ozone but such molecules are very dense and heavy (for Freon it is 16 times more dense than water or water vapor molecules and as a gas will sink in water and will not float in any gas the comprises or can comprise air) and the ozone is much higher in the atmosphere than any water vapor molecules have been found let alone the chlorofluorocarbons. So now we are wasting a tremendous amount of energy on a less efferent coolant which in turn results in the creation of more of the so-called greenhouse gasses. And all because of the self proclaimed environmentalist that have forced worthless legislation that is actually counter to the very cause they espouse. Please – this is all politics nothing to do with science. |
#104 James – since you asked, I have a PhD in Molecular Biology from Harvard Medical School and, yes, I believe that buildup of CO2 is from human consumption and that it will damage the environment. I think it is only one piece of the many ways we humans are damaging the earth. Will the earth survive? yes, will we as a species? who knows. Regardless, I also think your claims on the ozone are bunk – there was a nobel prize awarded for it to people much smarter than you or I combined. Do you really think that humans are not having a negative effect on the environment? Also, I don’t view this as political, it is ethical to me. #105 Herodotus – thanks for the link – it is a very controversial subject to say the least. |
Devyn S. For someone with a PHD in Molecular Biology from Harvard Medical School, I am stunned that you are concerned with the human production of carbon dioxide. First off, I think you have confused carbon dioxide (CO2) with carbon monoxide (CO). Since I did not attend Harvard I could not speak to the quality of education but I can speak to the difference between carbon dioxide (CO2) and carbon monoxide (CO). I would like to ask you some questions: 1. Other than breathing how do human produce carbon dioxide? |
Jonathon – I will not get into a pissing match with you about education. As for your questions, see these websites: http://www.eia.doe.gov/oiaf/1605/ggccebro/chapter1.html They clearly lay out the sources of carbon (and other pollutants) from fossil fuel combustion as well as a recent review of a paper demonstrating that plants don’t increase their CO2 uptake just because there is more CO2 around – Humans don’t increase O2 uptake just because there is more O2 around. Read these and if you want to have a discussion then lets discuss. |
Devyn: What your links say is really not all that clear and you will find all the questions answered at the following: http://www.junkscience.com/Greenhouse/ Enjoy |
OK – I send you links to government and scientific sources and you send me to junkscience.com which has no references and no bibliography. Not the kind of science I learned at that backwater where I did my Phd. |
The main problem is that scientists in this day and age are still attached to the flawed Baconian model which posits that corroborating evidence strengthens a theory. Thus, you get all of these climate models by computers that are written specifically to predict the past several decades of whether, and some scientists are stupid enough to accept the idea that there’s even the slightest probability that their predictions concerning the ensuing decades are correct. I’ve told this to scientist after scientist, and they all argue that the models mean that there’s at least some reasonable likelihood that the correlations posited by warming models hold. Earth to scientists: it doesn’t. I’ll tell you what: Create a model that predicts with a reasonable degree of reliability every twist and turn of the New York Stock Exchange or any the major currency exchange markets or any commodity or commodity future or other derivative market. Then use that model to do real trading and see if it proves as predictive in the future as it did in the past. (I’ll let you in on a little secret: These types of models have been designed, and they generally work less well than the more traditional approaches to trading.) The shame is that even scientists from Harvard maintain this superstitious attachment to these “climate models.” As far as the “science” of it, even those who believe in anthropogenic global warming disagree on what is being measured by current “global temperature” measurements. (here, here, and here; please take careful note of the bibliographies). Any reasonable scientist has to concede that the current metrics used to measure global warming are dreadful. Our cloud microphysics and ice physics are among the worst of those on any habitable planet in the Intergalactic Confederation. When it is so easily shown of global warming that it cannot be measured, I will not admit that theories describing it are scientific. It’s also a shame that Harvard scientists, to a man, opposed Star Wars based on the proposition that it’s scientifically impossible. It’s also a shame that scientists of every stripe pushed the AIDS hysteria by predicting heterosexual AIDS epidemics in North America (or even predicting that there would ever be a vaccine). I could go on and on. Lesson: Sometime between the Manhatten Project and the outset of the Thatcher-Reagan economic/military program, academic scientists transformed themselves into a political lobby peddling sensationalist doomsday scenarios. For a list of scientists who disagree with the global warming consensus, look here. Not all of them are notable. But you can’t credibly claim that they’re all hacks. The bottom line: Whether or not there’s such a thing as global warming, it is not a scientific position. It is a political position. |
DKL, Citing trading models is a bit of a straw man. A major reason that trading models don’t have the same level of success is that once they become widespread everyone has the same advantage and the model no longer gives you the edge it used to. The same interaction between the model and what is being modeled doesn’t occur in climate studies, unless the computer being used it so incredibly inefficient that simply running the simulation heats the entire earth. |
ARJ, actually, that’s false. It’s true of models that never obtain widespread use. In 1989, I designed several currency exchange models that accurately predicted the highs and lows of the 5 major currency markets since 1972 (it’s astonishingly simple — you’d be shocked; at the time, I was helping with a book on how to analyze cross-currency exchange rates, e.g., yen vs frank vs mark instead of yen vs dollar and frank vs dollar and mark vs. dollar, which is the way that folks tended to think of foreign exchange back then). You can use them to create trading systems that make successful trades with upwards of 90% reliability. They simply do not work for predicting the market beyond the date that they’re made. The reason for this is simple. First, for any given state of affairs, there are an indefinite number of theoretical explanations that can adequately explain it (this is known as the Quine-Duhem thesis, which is considered conventional wisdom nowadays). Second, let’s posit a hypothetical sampling of 6 explanations for the currency markets with the following date ranges: 1. 1972-1989 My data set in 1989 would eliminate #2 and #5 right out of the shoot, but it would provide no way of differentiating #1 from #3, #4, or #6. So the data set has radically underdetermined the predictive validity of my explanation. So it is with climate models designed to predict global warming. Back to trading: Since there are an indefinite number of such explanations, the chances of choosing one with any long term predictive validity are miniscule — even if one doesn’t use it to make money and thus condition the market to it. They are so small, in fact, that it’s safer to actually trade using more traditional means. I’m not positing anything revolutionary here. This is all reasonably mainstream philosophy of science. There is some sense in which the fact that scientists are ignorant of this makes them under-qualified. But there’s also a sense in which scientists have always ignored these types of factors, so that it’s just business as usual. |
DKL, Is that why BofA bought Financial Labs about a year ago? |
No. I’m not saying that algorithmic analysis doesn’t work. All trading systems are algorithmic by nature. The question is which one to use when. This winter, for example, would have been a bad time to use the cyclical algorithm on oil commodities and its derivative markets. But cyclical algorithms can still be used to great effect. Graph analysis is also liable to anomalies, and calculating when to abandon the pursuit of a given pattern is as important as understanding the pattern that you’re trying to identify. But I know of several very successful FX funds that use nuts-and-bolts graph analysis to identify buy/sell opportunities. Computer based trading models can mimic standard analysis rather easily. More specialized and elaborate computer-based systems have run into problems. Traditionally, these problems with computer-based trading systems have been two-fold: (a) that they work well in volatile markets, but not steady-up or steady-down markets, and (b) it’s difficult to create an algorithm which predicts long term trends that can effectively dictate aggressive trades — the need to lengthen the scope of the analysis has invariably resulted increasingly conservative trading approaches. Recent work has created algorithms that work within steady up and steady down markets as well as formulae that detect long term trends while allowing for more balanced trading triggers. The fact remains that such algorithmic trading bears no resemblance to the kind of models that I’m discussing. This kind of algorithmic trading is not designed to predict long term behavior or estimate the impact that some specific parameter might have on long term trends, For example, they can’t tell you “if the dollar continues to weaken relative to the Euro, what will be the impact be on the Yen in 5 years.” (climate models pretend to be able to parameterize climate in a manner similar to this). Trading systems are used to make snap decisions. Such algorithms are analogous to predicting weather, not predicting climate. |
So, I guess it has come down to this: some people think that global warming is happening due to humans while others disagree. Both want the appropriate money to continue their studies so it becomes political. In the end nothing gets proved or disproved and it remains a theory. If that is the case wouldn’t it be better to act like it is happening even if it’s not and reduce the human footprint on the Earth? |
No, it would be better if we all put our attention where it is really needed and follow the prophet if and when he speaks. |
DKL: Iagree with everything you’ve written in #111 and 113. I stand all amazed! |
Blake, I stand all amazed that you agree with DKL. ;>) |
DKL and cew-smoke have offered some well thought-out comments. Those who oppose them will have to do more than fall back on the scientific statis-quo. |
statUs quo. |
Blake, welcome aboard the Crazy Train! |
Devyn, I don’t think that China and India are emergent super-powers any more than Russia is. It’s not GDP that matters, it’s per-capita GDP insofar as it correlates to distribution of wealth among a populace. That’s why Isreal has been able to repeatedly hold its own against numerous Arab neighbors with more wealth. That said, by any estimation, it will be no more than 75 years (and possibly as few as 45) before China and India approach or surpass US per-capita GDP. But if you’re worried about fending off an aggressive China, the solution is simple: Re-arm Japan. |
DKL – To equate global warming models with the financial markets seems to make no sense to me. We cannot reasonable predict human behavior, however we can look at past behavior of the earth and make somewhat reasonable predictions about the future. This is the entire basis of science. While you and others may be astounded that scientists believe the global warming issue, I am amazed at the number of people who don’t think that human use of fossil fuels is a problem or that human pollution of the environment poses a threat. That astounds me! I will not get into a contest of throwing various sources at each other (although thanks for the sources – I feel like they back up my view), to me, there are some fundamental issues here – we are polluting the planet, we are putting out a lot of greenhouse gases, this will have some effect on the planet, and there are a lot of companies/scientists/people concerned about it. See the press release below for example: “Wal-Mart Backs Corporate Drive for U.S. Global Warming Legislation |
DKL – as for the tirade against sicentists in general, I have a few rebuttal points. Star Wars – yes, it may work at some point, but what a waste of money, AIDS hysteria – without the drug cocktails developed by scientists we would have a much larger problem in the US than we do have. It is a huge problem in the developing world. Most scientists think we will get to a vaccine eventually… Perhaps scientists are sometimes bullish where they should not be and sometimes bearish when they should not be, but I tell you there are a lot of really good, sincere scientists that I have met who don’t care about money, greed or power – they are just interested in understanding the world around us and making it a better place. |
DKL – finally, China – rearm Japan – I like it. I don’t necessarily agree that it is per capita GDP that makes a superpower. I don’t believe the USSR was very high in per capita GDP (I don’t have any data though), yet it was a superpower… |
Devyn: however we can look at past behavior of the earth and make somewhat reasonable predictions about the future. This is the entire basis of science. This is the flawed Baconian outlook, and it is incorrect both on an historical and a theoretical level. The fundamental basis for science lies in the bare fact that generalizations can succeed. Generalizations that can be refuted by critical examination are scientific generalizations, but they needn’t be based on observing past behavior and they needn’t be liable to predictive validity. There’s no reason a scientific theory couldn’t originate in a dream, and natural selection does not yield predictable results outside of formal systems that make such predictions a priori by subsuming natural selection into their axioms. The Ancient Greeks had science. Anaxemander theorized that a force akin to gravity kept the earth in place and Democritus invented the notion of the atom. I could go on and on. Almost none of science of Ancient Greece had anything to do with looking at “past behavior” and “reasonable predictions about the future.” Nor is this what scientists do today, even if many of them operate under the mistaken belief that it is. Besides, when it comes to using past behavior as a basis for future behavior, the question isn’t whether successful generalizations are possible, it is how you determine which generalizations are both successful and useful. You don’t do this by offering after-the-fact explanations, as is done by climate models. Your point about the financial markets is no objection at all. Nothing in my 113 is peculiar to financial markets. Feel free to reread it and substitute any reference to financial markets with the appropriate climatological verbiage. |
DKL, I’m sorry, can you explain again the method by which a reasonable theory of gravity can be arrived at without taking into account past observations? |
DKL – lets take evolution as an example. Darwin formalized what a lot of others had been dancing around in the 1800s into evolution / natural selection. All advances since that time in this field have built on his work. For example, now we know that nearly all of the genes found in a fruit fly exist in the human in some form or fashion and the genes involved in making the fruit fly appendage are roughly the same as those involved in making the human appendage. All of these discoveries built off of the work of Darwin and the countless others since his time. The other area in evolution where predictions are done all the time based on past knowledge is in paleontology. They find a little bone and determine what the bone is and what type of creature it came from then posit a probable time period it lived as well as some of its behavior. Subsequent finds of bones like that build off of their models. It is all based on previous research and pushing the envelope forward just a tiny bit more. In my mind this is no different from the climate change models. |
Wrong again, Devyn. Evolution also dates back to ancient Greece. Anaxemander was the first guy to theorize about it. What was lacking was a plausible mechanism to explain evolutionary process. Darwin supplied that mechanism in spades. Just the same, it provides no specific predictive information. The paleontology models created to aggregate evidence for reconstructing discrete species bare no theoretical resemblance to climate models that attempt to make long term climatological estimates. ARJ, it doesn’t really matter. For all we know, it came to him in a dream (in fact, very few biographical details are known about Anaxemander). It won’t do to posit an axiom that everything must come from previous observations and then assume that it’s got to be the case that everyone came that way. |
DKL – I would have to respectfully disagree with you. Many people had danced around evolution, but Darwin put it all together into a cohesive digestible theory leveraging the work of others. And it provides predictive information in spades – that is the beauty of evolution, we now have a way to explain the seeming randomness of the world around us. I don’t see the difference, you are using scientific theories to both build on past discoveries and make predictive hypotheses of future events/findings. That is the scientific theory. It does matter how it came to Anaxemander – if a scientist had a dream that resulted in some new grand theory, no one would buy it unless it was based on previous scientific data/principles. It would receive no credibility in the world. |
Devyn S: if a scientist had a dream that resulted in some new grand theory, no one would buy it unless it was based on previous scientific data/principles. Again, this is mistaken on both an historical and a theoretical level. Thomas Kuhn wrote an entire book demonstrating that this view is mistaken, though in my estimation he overstates his point a bit. You’ve made a simple mistake of reasoning. Specifically, the origin of a theory can be a good prima facie guesstimate of how worthy it is of further scrutiny. It does not follow that the origin determines the validity of a theory. In fact, the genesis of a theory is logically independent of its validity. Validity is altogether determined by how well a theory stands up to critical scrutiny (of which empirical tests are often a valuable component). Devyn: And it provides predictive information in spades – that is the beauty of evolution, we now have a way to explain the seeming randomness of the world around us. The explanations provided by evolution are all after-the-fact explanations. The continuity posited by evolution forms a theoretical component of many testable theories; e.g., the type you describe where a certain isolated bone is supposed to fit in a certain way into a certain skeleton. But it is not, itself, a testable proposition. Because we cannot predict which species nature will vote off the island (so to speak), when we say, “survival of the fittest” we’re not predicting who will survive; we are describing the current survivors. Nevertheless, “natural selection” or (as we prefer to think of it nowadays) “natural elimination” is the lynchpin of Darwin’s theory. It’s what places him among the greatest thinkers in the Western tradition. Nevertheless, the origin of the theory that the diversity of animal species is caused by evolution does date back to Anaxemander. Truth be told, it’s really not hard to look at the animal kingdom and see a lot of continuity. If that’s all Darwin did, then he’d be no more important than Lamarck (whom Darwin praised, and whose theory of acquired heredity he believed, which lead Darwin to mistakenly posit use and disuse as natural selection mechanisms). Darwin wasn’t just one more person positing continuity. He identified and described the mechanism by which it was effected. I’ll be quite a bit more specific than your statement that evolution “giv[es] order to randomness”; I’ll go so far as to say that Darwin’s theory of natural selection demonstrates how nature can exibit goal-directed behavior without requiring anyone or anything to set or direct such goals. It’s hard for me to articulate how perfectly brilliant this is. Just the same, it fails to yield predictive results. None of this is groundbreaking stuff. In fact, it’s all pretty much conventional wisdom. That’s why Blake and I can agree on it, though we often seem to agree on little else. I’m a logical positivist, and many people who don’t know much about logical positivism tend to believe that I hold a theory of science similar to the one that you seem to be espousing (viz., centered on the flawed Baconian model). Thus, I’m very well acquainted with your viewpoint, because I’m often having to distance myself from it. |
DKL, You’re perilously close to nonsense now. Why even come up with a theory if there aren’t past observations to explain? |
ARJ: You’re missing the point. The observations merely explain and organize the past without, in and of themselves, offering any predictive value for the future. Like the stock market models DKL references, past observations merely provide a probability coefficient regarding the future. The problem is that that coefficient is only as good as the universe of observations that lead to its formulation. With regard to climate change specifically, environmentalists are making an unsubstantiated claim that the data that went into the creation of their models is so complete that it makes the predictions generated by those models certain (or nearly so). Suppose that today I came up with a model that could accurately predict stock prices into the future but I could not substantiate that model with any historical observations. Would the lack of historical data make that model any less valid? |
arj, when you ask, “Why even come up with a theory…”, you’re talking about what motivates you to come up with a theory. I will not venture to enumerate all the different motivations that people have for theories. Theories serve a variety of purposes. I may invent a theory about how a certain piece of yet-to-be-written software code might work. Such a theory may come to me as the result of, say, hearing the lyric of a song or reading a line in Hamlet. And it is often fruitful to vet such theories using critical scrutiny before submitting it to empirical tests (like proof-of-concept prototypes or even full-on development). Since we see (ostensibly) near photo-realistic drawings of our solar system from a reasonably remote point of view, it’s easy to forget how abstract this topic really is, an to imagine that when people describe how the earth is situated in the universe that this somehow relates back to their experience. Needless to say, when Anaxemander (and those like him) posited that there are actually bodies of matter larger than the earth that were outside of his direct experience and that exert force on the earth to maintain the earth’s position in the universe, he was not leveraging previous experience. |
I assume that he had seen the sun (and had a rough idea that it would rise and set each day, at least in the past), the moon, and probably made some observations of the planets and knew that they all moved around in some regular manner. I’m not claiming that he had a top down rendering of the solar system to work from, but it is odd to think that the only source of inspiration might be a line of poetry. |
There’s no basis for such an assumption, unless it’s just a question-begging determination to explain everything in terms of past experience. What’s just as likely is that Anaxemander noticed that everything is somewhere, and proceeded to ask the question, “Where is the earth?” It distorts the nature of this question to try to cage it in terms of something in his previous experience. Moreover, Anaxemander’s theory doesn’t have any necessary relationship with the regularity of solar and lunar cycles. And why would anyone equate large bodies of matter with the bright lights in the sky based on the experiences available in Ancient Greece? Lastly, I think that it’s odd that you’d say “the only source of inspiration is a line of poetry.” I’ve used dreams as an example, and I’ve also plainly stated that previous observations can be used as the inspiration. My point is that the genesis of an idea has no logical relationship to its validity. It can come from anywhere — literally. As I’ve stated, the basis of science is the success of generalizations subjected to critical scrutiny — not previous experience. |
DKL – I would agree that the genesis of an idea can come from some other inspiration, but only after one has the basic knowledge (e.g., studied all previous work) to actually make the posit. Darwin had a great idea, but really it was a synthesis of a lot of other people’s work with whom he was familiar. Similarly, if you have a stroke of genius on some software, it is because you have studied enough to know what a stroke of genius regarding software is. I could never have that stroke of genius with software, (even if I was smart enough) as I have never studied it. Therefore, it comes back to standing on the shoulders of others… Seems like a circular argument here. |
Here is an interesting overview of the report coming out in two weeks on global warming. Seems like a bunch of smart scientists (600) have contributed to this report using 19 different computer models. DKL – what are your thoughts? ‘Smoking gun’ report to say global warming here Adjust font size: “The smoking gun is definitely lying on the table as we speak,” said top U.S. climate scientist Jerry Mahlman, who reviewed all 1,600 pages of the first segment of a giant four-part report. “The evidence … is compelling.” Andrew Weaver, a Canadian climate scientist and study co-author, went even further: “This isn’t a smoking gun; climate is a batallion of intergalactic smoking missiles.” The first phase of the Intergovernmental Panel on Climate Change is being released in Paris next week. This segment, written by more than 600 scientists and reviewed by another 600 experts and edited by bureaucrats from 154 countries, includes “a significantly expanded discussion of observation on the climate,” said co-chair Susan Solomon a senior scientist for the U.S. National Oceanic and Atmospheric Administration. She and other scientists held a telephone briefing on the report Monday. That report will feature an “explosion of new data” on observations of current global warming, Solomon said. Solomon and others wouldn’t go into specifics about what the report says. They said that the 12-page summary for policymakers will be edited in secret word-by-word by governments officials for several days next week and released to the public on February 2. The rest of that first report from scientists will come out months later. The full report will be issued in four phases over the year, as was the case with the last IPCC report, issued in 2001. Global warming is “happening now, it’s very obvious,” said Mahlman, a former director of NOAA’s Geophysical Fluid Dynamics Lab. “When you look at the temperature of the Earth, it’s pretty much a no-brainer.” Look for an “iconic statement” — a simple but strong and unequivocal summary — on how global warming is now occurring, said one of the authors, Kevin Trenberth, director of climate analysis at the National Center for Atmospheric Research, also in Boulder. The February report will have “much stronger evidence now of human actions on the change in climate that’s taken place,” Rajendra K. Pachauri told the AP in November. Pachauri, an Indian climatologist, is the head of the international climate change panel. An early version of the ever-changing draft report said “observations of coherent warming in the global atmosphere, in the ocean, and in snow and ice now provide stronger joint evidence of warming.” And the early draft adds: “An increasing body of evidence suggests a discernible human influence on other aspects of climate including sea ice, heat waves and other extremes, circulation, storm tracks and precipitation.” The world’s global average temperature has risen about 1.2 degrees Fahrenheit from 1901 to 2005. The two warmest years on record for the world were 2005 and 1998. Last year was the hottest year on record for the United States. The report will draw on already published peer-review science. Some recent scientific studies show that temperatures are the hottest in thousands of years, especially during the last 30 years; ice sheets in Greenland in the past couple years have shown a dramatic melting; and sea levels are rising and doing so at a faster rate in the past decade. Also, the second part of the international climate panel’s report — to be released in April — will for the first time feature a blockbuster chapter on how global warming is already changing health, species, engineering and food production, said NASA scientist Cynthia Rosenzweig, author of that chapter. As confident as scientists are about the global warming effects that they’ve already documented, they are as gloomy about the future and even hotter weather and higher sea level rises. Predictions for the future of global warming in the report are based on 19 computer models, about twice as many as in the past, Solomon said. In 2001, the panel said the world’s average temperature would increase somewhere between 2.5 and 10.4 degrees Fahrenheit and the sea level would rise between 4 inches and 35 inches by the year 2100. The 2007 report will likely have a smaller range of numbers for both predictions, Pachauri and other scientists said. The future is bleak, scientists said. “We have barely started down this path,” said chapter co-author Richard Alley of Penn State University. |
Four things: First, you know as well as I do that the release you site was put together by a PR agency and doesn’t bare the slightest resemblance to a genuinely scientific treatement of the topic. Second, the 19 models are meaningless. They could produce 17,586,241 models for all I care. There’s good reason to believe that long term climatic activity is irreducibly complex, and not theoretically capable of being modeled. Plus, the reason they have to keep coming up with new models is that none of the older ones have been able to predict the climate. Even a warming model that could accurately predict the climate for the next 5 years prospectively would be very weak evidence for global warming — and they haven’t even got that. Third, that has nothing at all to do with Darwin. Fourth, even many scientists who are widely acclaimed for their intellect are, in fact, rather stupid when it comes down to brass tacks. Take, for example, Carl Sagan. Total moron, that guy. He sued Apple Computer twice: Once for using his name as an internal code name for a computer, and a second time for re-codenaming the computer, BHA (for bone headed astronomer). It can truly be said that only a complete idiot would engage in such shenanigans. Oh, and did I mention that he also advanced an extreme (and implausible) version of the nuclear winter theory? That’s rationality for you. Sometimes I ask myself where colleges find these types. |
DKL – Second – I think we will have to disagree to disagree on this one. I believe that predictive (at least directionally) models can be created, while you do not. Third – it does have to do with Darwin. This is evolution and natural selection at its best. Will we survive? What species will besides rats, house flies, and cockroaches? Fourth – I don’t disagree there. I am usually in that camp as are many of my scientific colleagues… |
Rest assured: We’ll survive global warming. Rat’s don’t hold a candle to humans. |
Sadly, you are right, sometimes it is hard to distinguish between the rats, cockroaches, and humans… |
I’m pretty sure that BHA is widely understood as Butt Head Astronomer. |
Thanks, arj. In my continuing attempt to remain the most tasteful blogger in the ‘nacle, I was hoping to avoid such vulgar terms as “butt,” “ass,” “asswipe,” and “asshead.” BTW, Devyn, it’s worth noting that you’re statement that market models fail because we can’t predict human behavior is a text-book example of the fallacy of composition. |
I know I’m late in the debate, but I think the two most compelling things illustrated by this discussion are: 1) The difference between Fact and Truth The first is from amply quoted facts from both sides of the issue, neither of which help to determine truth. The second is the oft-repeated, slightly ascerbic comments from both sides about the other side, and that both sides are mildly mud-slinging and insulting each other and using the terms “Democrat” and “Republican” like invectives. It really shouldn’t be about politics or which color of shirt you wear. I’m not entirely convinced for either side. I feel we just can’t know. At the same time, I think it’s good policy to do what I can to conserve waste. Therefore, I drive a “practical” vehicle, use energy-saving bulbs and make efforts to insulate my house and recycle where I can. I think it would be much easier to institute recycling and conservation programs if people in general stopped throwing mud back and forth across the political line and realized that both sides have reason to conserve, whether it be environmental or financial, that neither reason is invalid or stupid, and then worked together to make it more cost-effective and practical to be cautious with our resources. |
SilverRain – Your approach is probably the correct one, but it is kind of fun to bash the Publicans… |
I’m even later in the discussion, but I read the whole dern thing, so I’ll at least say my bit: In the Book of Mormon, a text in which I assume we all have some degree faith, or at least appreciation, the issue of human impact on the environment (of which global warming is an example, but not the only one) is treated, somewhat obliquely, through scriptures concerning the land of Desolation. In Helaman 3:5-7 and Alma 22:31 we learned that the land to the north had been severely deforested, to such an extent in fact that the animals inhabiting the area had all moved south in search of food. This “desolation” we will remember was the result of, and a significant factor in the collapse of the Jaredite civilization. The Jaredites were relatively isolated from the rest of the world. Even if we are so naive as to imagine that they occupied the whole of the North American continent (not very likely) their collapse had little if any effect on the world as a whole, other than open up land for occupation by Nephites. They had no political, no economic ties with any countries on the other side of the globe. Their energy resources did not depend on the political stability of nations thousands of miles away. They had only the land the were given, the wisdom of their leaders, and the righteousness of their people. We are told that the Book of Mormon is a message for our day. In it we read of the collapses of two civilizations. In both cases their prophets pleaded with them until the very end, but the people were too “wicked” to listen. As we learn from the example of the Jaredites, one symptom of a wicked people is over exploitation of resources and degradation of the local environment. I write these words from Thailand (my wife quietly suffering in bed with a rash brought on by air pollution), a country no less cellphone, iPod and SUV obsessed than the USA, despite the current military junta’s desire to “simplify” and backtrack. The fact that they are poorer does not limit their aspirations, but instead makes them that much grander relatively speaking. We are quickly becoming one civilization (actually, I think we have been for some time), and the actions of one country have can have repercussions around the world (the 1997 financial crisis originated right here). At this point in our civilization’s history there is no such thing as a strictly local environment. It’s all local. And just because your own back yard in the Whatever Valley, UT happens to be green and peaceful doesn’t mean that someone else’s desert isn’t blowing sand your way. Did you know that China’s soil (and our own) is being blown onto the Rockies as we speak, darkening the snow and making it melt faster? Do you people know where your water comes from? I’m sure annegb has moved her defeatism and ignorance to greener digital pastures, but let me just say that I am ashamed to belong to the same church as her, and those that agreed with her in this discussion. If we are told to study the scriptures (BoM in particular) and follow the examples of the prophets, prophets who fought for their people, for their civilization, until the end, how in the world can anyone justify such a stance? I for one will follow the admonitions of our prophets and seek after “anything that is virtuous, lovely, or of good report or praiseworthy,” regardless of whether it comes from that “putz” Al Gore. If there are virtues in the environmental movement (virtues like, frugality, conservation, self-sufficiency), and means to more fully magnify those virtues in myself and in my community, then we should embrace them without waiting for church leadership to tell us specifically to “go Green.” |
Anyone else enjoy the latest Economist ? “The greening of America” … |
Grrrrrr. http://nofolete.blogspot.com/2007/01/mormon-mentality-and-global-warming.html |
Chino- Encouraging, though it’s sad to think that we, as a church, are being left behind. But that seems to be our MO. |
nofolete – thanks for the thoughtful response. I would agree with your thoughts and assessment. It is sad that we, who should be very responsible stewards of the environment can’t learn from the past. However, every time I go to Utah, I can’t help but think of the Nephite pride cycle anyway… |
nofolete thank you for your thoughts! it seems like good common sense to protect the environment (our home) and yet… |
#148, this is sort of what I’m saying. I think those who give this message in America are preaching to the choir. We have a pretty good environment here, even though, of course, there is room for improvement. Sensible improvement, not crazy stuff. The rest of the world should live up to our standards. That said, I’m not worried because the second coming is supposed to be here already and God is already overdue and He will clean up Lake Baikul. |
I’m sorry annegb, but if you think we agree on anything, I’m afraid you misunderstood me somewhere. I don’t think we should live merely decent lives, but rather exemplary ones, meaning radical change. If the rest of the world were to live up to our standards the results would be appalling. In the US we consume 20,030,000 barrels of oil per day. That’s more than China (6,391,000 bbl/day), Japan (5,578,000 bbl/day),Russia (2,800,000 bbl/day), Germany (2,677,000 bbl/day), and India (2,320,000 bbl/day) combined. Those countries are the top five oil consumers after the US, and have a combined population of 2,790,097,000. Nearly half the world’s population. Actually, about 300,000,000 shy of half, which happens to be the US population. As proud citizens of the USA we use, individually, .0667 barrels of oil per day. That doesn’t sound like much, but if our other buddies in the top six were to consume just as much their combined usage alone would top 186,285,476 barrels a day, or 67,994,198,877 bbl/year. And if the rest of the world were to live up to our standard, well, I don’t even want to do the math. The numbers for energy consumption, CO2 production, water consumption, waste accumulation, etc are just as grim. Much of the clean living, natural beauty, health, and happiness we enjoy in the US are the result of shipping our problems elsewhere. I happened to serve my mission in one of those places (the Dominican Republic) and I live in one now. On the flip side much of the clean living, natural beauty, health, and leisure we enjoy in the US are the results of work done by wacko environmentalists, labor organizers, and other lefty nutcases endorsing radical change. That said, I wonder why the second-coming isn’t here yet? Maybe God is giving us a chance to repent and clean up Lake Baikal on our own. After all, the atonement is contingent upon our repentance. |
“Much of the clean living, natural beauty, health, and happiness we enjoy in the US are the result of shipping our problems elsewhere.” “On the flip side much of the clean living, natural beauty, health, and leisure we enjoy in the US are the results of work done by wacko environmentalists, labor organizers, and other lefty nut cases endorsing radical change.” nofolte. THANK YOU!!! The two comments i quoted are pretty much the response i would have made to her and to the rest of the folks out there that believe that the US is doing a swell job of managing it’s resources and environment. |
Happy to oblige. |
annegb, fyi, i am one of those nut case environmentalists. I am one of many that funds and works towards creating that environment that you think it pretty good. do you honestly not notice the work that is being done? |
Devyn S: Sorry for my absents; I do not have time to play everyday on the internet and from time to time miss some follow-up. Allow me to talk a little real science. 1. What happens when a heat sink (space) completely surrounds a heat supply (earth)? There is a heat transfer – true or false? All that your sources (links) said is true. When heat is absorbed into atmosphere with carbon monoxide and carbon dioxide heat is not radiated at the same rate but conduction must be added to the equation because the wave length of the heat is changed and by definition cannot be called radiation. So carbon does not radiate heat into space but heat is still transferred my friend and not one of your “government†links or your PHD seems to understand these simple laws of physics. WHY? Because there is not a biography? Please! All of these simple laws of physics were explained in my link and well as any “real†text book on thermal dynamics. Do you even have one? (Meaning a text book on thermal dynamics) Have you looked at it? Do you understand the difference between radiation and conduction? Please show me anywhere in your “official government†links that I can read about heat being “conducted†(not radiated) from earth carbon atmosphere into space. If you can do that I will apologize to you and eat crow. BTW – I worked on “stars wars†and it will not work. In fact our ICBM are not the answer many think and cannot be fired over the North Pole and accurately hit a target. Is there anything in your PHD that will tell you why? Would you like me to tell you? Do you know why we do not hear much about ICBM anymore? Sorry these questions are off topic. Jonathan M |
By the way, the people at co2science.org are totally evil, I don’t care what ward they belong to. They take a perfectly good, peer-reviewed study offering corroborating evidence for global warming, like the northward expansion of larch forests on to the tundra (due to the melting of the permafrost), and say that, in their opinion, it’s because CO2 is an excellent atmospheric fertilizer. When you do that to the scriptures it’s called “wresting.” |
Mfranti: So you are a nut case environmentalist. I have dealt with your type concerning the environment before. Yes. I was living in Seattle when St. Helens erupted and millions of usable board feet of lumber was knocked down. When the evil lumber industry tried to salvage the lumber the nut case environmentalist (Sierra Club) blocked it in the courts claiming the forest would return better if the lumber was left on the ground – which was not true. You failed to consider the environment before your own selfish political agenda. Please understand we can improve the environment by intelligent management which can be much better than no management or leaving nature alone to manage it. Jonathan M |
i don’t recall participating in the mt. st helens issue. but thank you for letting me know that i have a selfish political agenda. (you should let me know what it is) i am so glad that there are folks out there who have all the truth about whats going on in the world. i guess it’s because you got all sorts of fancy initials after your name. |
Wouldn’t ignoring global warming count as “no management” as opposed to “intelligent management?” Or is this just part of broader plan to get rid NYC, Holland, Bangladesh, New Orleans, South Florida, and Tuvalu, all of them veritable blights on our globe, and true enemies of freedom. If only Iraq were below sea level. |
Jonathon M – Again I am not going to debate science with you particularly given your condescending tone. You believe certain things that I do not. Therefore, when we get to heaven (assuming I do) then if you are right, I will buy you a heavenly drink. Otherwise, I think there are a lot of people smarter than I am (and maybe you) who have worked on this and the vast majority say that humans are having detrimental effects on the environment. Given that, it seems silly to try to explain why they are wrong instead of taking steps to fix the mess. Intelligent management on the environment is better than the earth managing itself – hmmmm.. a bit presumptuous given we humans have been here a couple of million years tops and the earth has been managing itself for billions of years. |
jonathan, do you suppose that blowing off the tops of mountains for coal (very very dirty stuff too)intelligent management? |
[...] blogs have discussed climate change a lot, such as today’s post at BCC or the still ongoing discussion at Mormon Mentality. This discussion of the human hand in climate change is probably worth reading as [...] |
Some things: Mfranti: It is you that called yourself a nut case environmentalist type. I thought you might have sympathy for the Sierra Club type environmentelest and identify with them. Please clarify if you are Sierra Club environmentelest nut case type. If you are not this type – I apologize. If you are that type – please take note that I have proof that you guys are too extreme and too politically self serving for me to be impressed. To other posters – not everything mankind has done in the environment is intelligent – Why are you asking about stupid things? Are you unaware of any intelligent things? Something else Devyn – just because someone is smarter than me does not mean they are right. I have learned, by sad experience, to ask smart people questions before I buy what they are selling. It is nice that they are smart but if they cannot answer my questions they are of no use to me. I learned in college that most professors do not know what is in the text book that they wrote themselves and if I asked them about what appeared as a mistake in a text book that they wrote – I expected them to answer correctly and honestly. If they insist in the “I am the professor and I am the one teaching†mombo jumbo stuff. I would just reply that I was paying to be taught and I would find a teacher capable of teaching this subject. Understand – I agree there is global warming. I am not sold on the idea that it is all (or mostly) because of greenhouse gases. I would point to Antarctica that has an average temperature rise of 3 degrees, the highest warming on the planet. Check your web sites my friends, a few years back Antarctica was the poster child for greenhouse global warming. Anyone, other than me, checked this out – What is the cause of global warming in Antarctica – Big clue – it is not greenhouse gases, despite that prior to a real scientific investigation every environmental scientist (all of which are most like smarter than me) agreed that it was because of greenhouse gasses. The world’s best and smartest experts made a mistake. Anyone know what that mistake was? Jonathan |
“nut case environmentalists” You said it, I didn’t. |
Jonathan M, I can’t believe you seriously claim to have a physics background. Conduction of heat requires atoms, which are in short supply in the vacuum of space. Thus, the only method for heat to escape the earth is through blackbody radiation. Oh, and it’s thermodynamics, not thermal dynamics. love, your friendly, local paleoclimatologist. |
fwiw, I don’t think it’s all that interesting to single out annegb, how about a little exegesis on the apparent agreement between DKL and Blake on this issue … is it down to a shared blind distrust of “liberal whack jobs” or just character types that enjoy waging rearguard rhetorical battles? btw, anyone happen to catch the latest SOTU? What a “nut case” ecowarrior that Bush has become, huh? |
Chinito- No kidding, cellulosic ethanol? The man’s gone off the deep end. As for picking on annegb, I realize it’s a bit unfair (I’ve read some of her posts, and I’m sure we’d get along fine in meat space, any friend of Emily Dickinson is a friend of mine), but my beef in my initial response was with people who imagine that the church or its teachings somehow excuse them from taking responsibility for the environment. People who want to argue on political or imagined scientific grounds have plenty of other places to do so. Kristine N- I thought about responding to him, but the amount of CO2 and waste heat my computer would have generated in the process would have contributed to both global warming and the eventual heat death of the universe. So I decided against it. |
Chino – I loved the Bush speech – sounded like a true blue Democrat. Yesterday at a committee meeting John McCain said that “the debate over global warming is over, it is time for action.” It is great that the Republicans have finally awakened to the fact that humans are destroying the environment and the US is, unfortunately, is leading the destructive charge. Kristine – thanks for the response. I have refused to get into the debate with someone who references junkscience.com (which has no references to scientific papers) and thinks that sites (with references) that I refer him to don’t understand science like he does. Jonathon M – just because hundreds of people are smarter (or as smart) than you and they all agree against your view does make them more right in my opinion. In addition, it seems that the Bush administration finally sees the environment as a cause worth fighting for so your allies are dwindling my friend. I will see you in heaven when we can settle this by asking the “big guy” himself. |
nofelete, I didn’t mean that we were in agreement. I meant that your post about the situation in Thailand echoed one point I was trying to make in that the US is more eco-friendly than much of the rest of the world. America certainly didn’t contaminate Lake Baikul or force Thailand into whatever is occurring there. Americans are, on the whole, clean and industrious people. What is beginning to trouble me about this interchange is the assumption that those of us who are not worried about the environment are sitting around on our butts eating bon-bons and watching soap operas. There are many important issues in the world today, environmentalism is only one of them. No one can do everything and my refusal to jump on what I perceive to be an extremist bandwagon does not necessarily equal ignorance or complacency. Perhaps those who espouse, rather harriedly, a total activism on the part of the environment will balance out with those who espouse, rather harriedly, other important issues, like the murky environment in the soul entertainment, for instance. I truly do believe that God will take care of things. I just do. I also believe that those of you who go overboard in making your point are coming from a place of fear and insecurity rather than faith. We can all agree that we need to care for our own backyards, be it in southern Utah or Afganistan. There is no need for polarity. There is much to be done in the world besides trading in ones’ vehicle for a bicycle. |
annegb, I’m not sure we are assuming you’re sitting around eating bon-bons and watching soap operas. I think most people are working hard at whatever it is that concerns them most–whether it be caring for their families, pursuing a rewarding career, or trying to positively change the world around them. The point is, we all get fixated on whatever issue screams the loudest for us, and while we don’t necessarily mean to ignore other problems, we do let them slide. We have to prioritize, and I think the environment is very easy to make a very low priority. I get the impression that those who want the church to take a stand on issues like the environment want to raise the importance of that issue in the consciousness of others who might not care as much. Devyn, I admire your question, but I’m not convinced it’s the church’s place to say anything about global warming. Of course, I also think the church should say far less than it usually does about politics. I for one would be uncomfortable if the church leadership became more political. That said, I think we as a community of more or less like-minded individuals should engage in discussions about environmental topics, letting our common moral system guide us toward what I hope will become a coherent approach to environmental topics. I think there is a lot to be said in favor of our community (and note, I do not say our leadership) coming out in support of CO2 limits. There are issues of social justice and equitable parceling of resources that are just as important an aspect of the global warming debate. We as americans do work hard, and we have a pretty darn efficient system going, but it’s not efficient enough that it could be extended to every person on the planet. Unfortunately, there’s a lot of institutional inertia in the US that makes it impossible as an individual to do a whole lot about reducing CO2 emissions without living a sub-standard lifestyle. I do think we live in a society that values conspicuous consumption, though, and I completely believe that by buying into that conspicuous consumption we not only do harm to the environment, we also do harm to our souls and to our relationships with other people near us and far away from us. |
Concerning Greenhouse gasses and reradiation of infrared radiation they adsorb. Simple physics demonstrates that gas molecules containing carbon are heaver than other molecules commonly comprising air and thus are not expected to be at the levels of space. Note that carbon molecules in a room are to be expected at the floor and not at the ceiling. Thus the greenhouse gases will not comprise the majority of atoms of the higher atmosphere. Also note that the temperature of molecules drop significantly as altitude is increased. Kristine N. Why do you insist that carbon molecules can only conduct or give off energy directly to outer space and nowhere else????? Why do you discredit any other view point???? Please deal with the physics of the issue. Since we are concerned with greenhouse gases absorbing energy and not passing (conducting) heat on to other molecules in the atmosphere as unproven and I say with authority that I do not believe that it does not or cannot happen. I think those that say it does not or cannot happen are making a grave and silly mistake. BTW Kristine – Thanks for the spelling lesson – That is very much a weakness of mine. Sometimes I make fun of my problem and tell people that if they only know one way to spell something they are uneducated. But for now I apologize and accept your rebuke of my spelling. Again I would point out that all the world experts have from time to time been wrong. The posters here seem to be concerned about global warming. I ask again for the reason for warming in Antarctica which is the greatest example of global warming on earth. All the experts, with out exception blamed greenhouse gases up until about 5 years ago. What changed their minds and why is there no recent information anywhere about global warming in Antarctica currently? I challenge anyone to provide a link – It took me 4 years to find one and it would make a difference to the nut-cases on this forum – I will provide it but if you are going to hold to a unsupported view and blindly blame opposition then I would just as soon you continue to look the fool and remain ignorant. Come on you experts this is a simple question – if someone cannot answer this question about global warming they are not qualified – AT ALL – to force a political agenda concerning global warming. It is simple my friends. If they cannot answer this question they are fools that have not investigated the matter. They lie when they say they are informed. I do not care how expert they are or claim to be they just do not know what they are talking about. Devyn: I think of myself as a human individual with agency – I am not a human lemming following the all experts over some intellectual or popularized cliff. Why can’t you consider global warming as the result of anything other than greenhouse gases? I do find it ironic that many environmental types say they believe the experts when they agree with them but then turn around and say that experts cannot help make the environment better. Saying only nature, on it own should have input to environment change – I find that thinking contradictory. Jonathan |
BTW – I keep bringing up Antarctica because of the environmental problem is far greater than all the problems claimed with current global warming problems. We have the greatest pending (or one of the greatest) environmental disaster to have ever known to have taken place on earth. Nothing is being done and no one cares. The problem is that humans cannot be blamed and there is nothing that can stop the disaster so there is no political advantage for the so-called environmentalist. No political advantage translates into no attention. All the experts on what is happening in Antarctica have made warnings to deaf ears and uncaring ears. Jonathan |
annegb- “I love to read and lay around and watch TV and eat junk food. I don’t have too many aspirations beyond getting the dishes done and serving dinner to my food-slut husband.” Sorry if I got the wrong impression. Look, I don’t expect you to go out and become an environmental activist, nor do I think most members of the church should. There is plenty of good that can be done in the world, and I’m sure you’re anxiously engaged in your own area of concern. What I am asking is that those of us who do chose to focus on those particular issues not be antagonized by fellow members of the church. Especially when there is scriptural precedent for concern and action over environmental issues, and plenty of overlap in values between environmentalism (values I listed earlier, like frugality and self-sufficiency) and the church. I don’t think changing out your incandescent light bulbs for compact fluorescents is extremist. I don’t think recycling is extremist. I don’t think conserving water, electricity, or gasoline is extremist. Nor do I think they are based on feelings of fear or insecurity when they are in accordance with some of our core values as members of the church. Each of us has been endowed with our own free agency (as you well know), and the world we create emerges from each of those individual actions. I don’t want to limit the good you do in the world, please don’t try to limit the good I do by saying there’s no point. Thank you for your last comment, I feel I have a better idea where you’re coming from. One more point, of general interest, on the rest of the world living up to our standards. As cleaner, lighter-weight substitutes for current technologies are deployed in developing nations, I actually think there is at least a (teensy-weensy) chance that they might do better than us. In the US our switching cost is greater since we are tied to our current infrastructure. It’s possible to envision a near future where currently struggling nations far outstrip us in quality of life while we struggle to catch up. Oh, the irony. |
Jonathan, am I correct if I summarize your argument thus: I think scientists who actually work in field of climate change are concerned because in addition to the poorly understood mechanism of global warming caused by the sun (an estimated 0.6Ëš in the past 100 years), human beings are generating enormous amounts of gasses (not just CO2) which have a well documented correspondence to higher temperatures here on earth (acounting for the other 0.4Ëš). In other words, we are making a bad situation worse, since many of these processes are feedback loops–increased CO2 leads to higher temperatures which lead to increased CO2 or CH4 (as previously sequestered sources of methane and CO2 are exposed by melting ice). By focusing on the anthropogenic side of the equation (greenhouse gas) I’d like to think we are merely being pragmatic. But then I’m just an art fag, not a rocket scientist (or does that mean you’re just an engineer and care little for hard science). Are you one of those who think we should launch giant sunshades into outer space? |
Nofolete: Thank you for your interest in my ideas and concerns. If you (or others) have ever dealt with the “experts†in the medical profession you should understand the importance of a second opinion. The reason for a second opinion is not to see if you can get the same information form a different source – The reason is to get a different view and hopefully different information in order to arrive at a more conclusive result. Alternate opinion is essential to scientific method producing solid scientific results. An infrared heating source experiment. Try this yourself. Using an infrared heating source experiment – take an object that will adsorb infrared heat (like dirt from the earth’s crust or even some glacier ice – or if you do not have glacier ice try packed snow) and see what happens when it is exposed to a infrared source (you can use a red light like they use at McDonalds to keep your food warm). What happens if you increase the intensity of your heat source? – Easy answer, your ice and dirt will become hotter. Another experiment. Take hot exhaust from your car (lots of CO) and expose it to cold air. What happens? Does the CO retain heat? It looks to me that CO is as happy to give up heat as other gasses in air. My understanding => more radiant heat results in increased heat especially at the point (earth surface) where the heat is absorbed. Second thought. Has earth experience climate change without modern man’s help? Answer = yes. Is climate change (because of man) within the parameters of what happens without man? Answer = yes. Final thought: I believe there are a lot of bad things we are doing to the environment as humans. What I do not believe is that the current levels of CO or CO2 are the biggest and worse problem. I have listened to the crowd that calls themselves environmentalist. At one time I was even a member of both the Sierra Club and Green Peace. I am convinced that what we are seeing is more the results of politics of power than Science or true care. Does politics play in science? You better believe it – 50 years ago the scientific community told us that Dinosaurs were cold blooded reptiles. This is because of the opinions of the top experts – not because of science. Anyone with a different opinion was considered “outside†the community of experts. One short story for those that do not mind. 30 years ago I was part of a group providing information for legislation concerning drug use by minors to the state of Washington. I presented and testified concerning death rates among minors from immediate anaphylactic shock related to tobacco products (not even considering long term effects). There were powers in the legislature that did not like this information. My testimony and statistics were stopped and voted to be removed from proceeding. They no longer existed. It was published that a number of things were agreed to – but missing was the data and information I brought. The public was never informed that the drug tobacco caused more deaths among minors (by anaphylactic shock) within the last year in the state of Washington than was caused by the drug that was being banned for the last 10 years in Washington. It was not about saving the lives of our minors – it was about politics. There is a principle of Communism that says that if the masses are told something enough times (regardless of its truth or relative truth) they will believe it – not because it is true but because they have heard it so many times. I have yet to see any data – I repeat: any data that indicates CO and CO2 is the cause of global warming and that by reducing CO and CO2 will change the global warming trend. In fact from all that I know H2O (clouds) in the atmosphere has much more of a greenhouse effect but no one will admit that H2O could contribute at all to the problem. Why??? Could it be politics – shame on me for suggesting such a thing. Jonathan M |
Jonathan M… Wow, where to start? First, I’d like to know exactly your training in physics. What have you had and where did you obtain your degree? If your professed physics knowledge is representative of the quality of education received by you and your fellow classmates, your alma mater should lose it’s accreditation. You appear to have just enough physics background to be a serious danger, if not to yourself, then perhaps to others. You seem to spout a lot of half truthes and a fair amount of nonsense. This kind of pseudoscience crap is what all too many people are occasionally lead to believe. Now that I have insulted you, perhaps I should give you my pedigree. I hold a Bachelors of Science in geophysics from the California Institute of Technology (aka Caltech), a Masters of Science in geophysics from the University of Utah and am currently working on my Ph.D. My research mainly involves thermal geophysics with particular applications to the lithosphere, although my research group is heavily involved in global warming research. Much of my undergraduate focused on planetary and environmental science which deals a great deal with the subjects of the atmosphere. Now that you know my credentials, I’ll comment on a few of your posts… 1. I’ll start with the empty arguments. Empty arguments are statements, although occasionally true, hold no real meaning and are not scientific in nature at all. From post 167 “There have been several “natural” disasters that have had far more detrimental impact on the environment of the Earth (including climate) than anything and all things done by man.” Yes, but why does that mean we shouldn’t try to prevent potentially harmful man-made environmental impacts? You’ll also noticed that I capitalized “Earth” in your quote. It is our home and deserves our utmost respect (after all we capitalize Mars, Sun and Moon). From post 175 “Again I would point out that all the world experts have from time to time been wrong.” Everyone has been wrong from time to time, yes even experts, but when there is a large body of scientific evidence that supports a theory, experts are usually pretty darn good at getting it right. “Come on you experts this is a simple question – if someone cannot answer this question about global warming they are not qualified – AT ALL – to force a political agenda concerning global warming. It is simple my friends. If they cannot answer this question they are fools that have not investigated the matter.” What kind of a response is this? Sounds like a whiny little kid. No one is omniscient aside from perhaps God. One doesn’t have to know every little detail to be qualified to answer a question or make a political statement. Although I would not advocate letting scientist run things as we tend to be terrible economists and poor in understanding of many social matters. I’d suggest that the members of Congress are less qualified to make a political decision concerning a scientific matter than a scientist (I’d like to remind you of a wonderful Mark Twain quote: “Suppose you were an idiot and suppose you were a member of Congress. But I repeat myself.”) Scientists should play this advisory role and it is up to our elected officials to weigh the societal/economic/environmental benifits/detriments. From post 179 “There is a principle of Communism that says that if the masses are told something enough times (regardless of its truth or relative truth) they will believe it – not because it is true but because they have heard it so many times.” Perhaps, but talk to anyone from a former Soviet block country. Many will tell you that once they could receive television images from the “west” they knew that the Soviet Union and communism was not all it was hyped up to be. 2. If you really profess to be a scientist/engineer and have worked on “Star Wars”, then please at least get your terms correct. Molecules “absorb” radiation, not “adsorb”. Adsorb is a different process entirely. 3. Atmospheric physics… 101. kristine N was quite correct when she told you that heat is not conducted into the vacuum that is space, but is radiated. We commonly refer to this as the Stefan-Boltzman law of backbody radiation. Heat is transfered out of the atmosphere into space via electromagnetic radiation, not conduction. Conduction is a process that requires interaction between particles. Is some of the Earth’s heat transferred to space by this mechanism? The answer: the amount of energy transfered to space from the Earth via conduction is so small that it is negligible. Your statement: “When heat is absorbed into atmosphere with carbon monoxide and carbon dioxide heat is not radiated at the same rate but conduction must be added to the equation because the wave length of the heat is changed and by definition cannot be called radiation.” Conduction is a heat transfer process that involves “phonons” not “photons”. Phonons are imaginary particles that transfer the energy from one atom or molecule to another (much like image charges in EM). This process does not involve the transfer of electromagnetic radiation, “photons”. Thus there is no “wavelength” to speak of, only energy quanta that are passed from one particle to another. (Pick up your solid state physics textbook for an explanation as I am sure you have one with a significant training in physics.) I might also mention that the dominant mode of heat transfer in the atmosphere is through convection, i.e. the physical transport of air, not by conduction which you so fondly speak of as the only mode of heat transfer. (A good thermal physics textbook like Carslaw and Jaeger, Conduction of Heat in Solids can help you with the different modes of heat transport.) This brings me to my next point. You talk about the density of the various constituents of air and the impossibility that certain molecules (CFC’s and CO2) can end up at certain levels within the atmosphere. Apparently you didn’t realize that our atmosphere is well mixed. Convection is a dominant mode of chemical transport as well. CFC’s most certainly do affect the ozone layer in the upper reaches of the atmosphere. They have been detected via satellite observations. You certainly must be aware of the research surrounding this since you were once involve in space technology. Now let me reduce the gas distribution argument to absurdity. If CO2 is heavier than O2 and O2 is heavier than N2 and N2, then why isn’t our atmosphere stratified? Why aren’t we taking healthy breathes of pure O2 or unhealthy breaths of pure CO2? Greenhouse gases. You mention that many of the papers that cite the effect of greenhouse gases site previous research that includes the numbers from previous studies which may site the number from previous studies, none of which provide the actual data. True, this often appears to happen, but if you were to trace back the references far enough, the original data and methods by which they are determined are cited. In fact Svante Arrhenius knew about this about 100 years ago. What, I hear you say you still don’t believe that they are greenhouse gases? Well let me explain to you how a greenhouse gas works. Every molecule or atom has an absorbtion spectra for electromagnetic radiation. Each with a different and unique spectra. Glass, or the base chemical component, SiO2, is transparent to visibile light. Hence, we can see right through it. Coal on the other hand absorbs a great deal of incoming visible light and as a result is nearly black. There are certainly intermediate values. For instance, aluminum is a light silvery color because it absorbs some but not all incoming radiation. How much? Well that depends on the intensity of the light and if it is at the appropriate wavelengths. But the ratio of incoming light to the reflected light gives us an indication as its potential as an absorber. H20, CH4 and CO2 all have significant absorbtion bands in the infra-red. This is easily measured in a laboratory and has been well known for a long time… In fact this is how we can determine the composition of the atmospheres of planets without having to test the gases directly. Still don’t believe me, find an introductory planetary science textbook (Beaty, Petersen and Chaikin, The New Solar System, will do). Ok, now that we have established that CO2 will absorb incoming solar radiation in the infra-red band, how does that make it a greenhouse gas since it will most likely want to rid itself of this extra energy to its surrounding lower energy environment? Some of it is re-radiated into space, some is passed onto other molecules in the atmosphere in the form of kinetic energy (this is proportional to temperature) and some is passed on into the ground and oceans. In fact, the ground and oceans store much more of the incoming radiation than the atmosphere does, so that when the air cools it is heated from below as well as the Sun above. Although the Earth wants to cool if more greenhouse gases are added to the atmosphere, the amount of incoming radiation captured is greater, thus warming the planet until a new equilibrium temperature is reached. It is also more difficult for the heat to escape since an increased concentration of greenhouse gases also prevents the escape of IR by playing a fun physics game called atmospheric pinball. Although some escapes, it now takes much longer and the globe continues to warm. Want an extreme case of this game? You have to look no further than our planetary sister–Venus. Your statement “The claims about carbon monoxide as harmful to the environment have long been proven junk science because carbon monoxide becomes carbon dioxide when introduced to plants performing photosynthesis which gives of oxygen. And carbon dioxide is necessary for plants to survive and the more of it there is the better plants do – which means the better crops will do and the better we will be able to feed the hungry.” First of all, the CO becomes CO2 as it interacts with O2 in the atmosphere, not as a result of photosynthesis. Plants use CO2 and convert it to O2. I’m not a biologist, but you may want to check your source here. CO is of course very harmful to humans as I am sure you are aware. CO is very poisonous as it binds to hemogloben in our blood and prevents the acceptance to O2. In essence, we suffocate while breathing. Second, and this is pretty new so you may have missed it. You are talking about the “Greening of the Earth” hypothesis which many anti-enviromental groups try to espouse as a good thing that we burn fossil fuels. It turns out that while it does in fact increase the productivity of plants significantly (especially for poison ivy), this increase appears to be quite temporary. There are some new studies which have shown quite conclusively that although plants increase in productivity initially, their rapid increase in growth comes to a screeching halt with time as other nutrients now become the limiting factor and get sucked rapidly out of the ground. Additionally, you could say bye to trees then since it is the grasses which will do best in this sort of environment. Trees will not be able to keep up as their life cycle is significantly greater and they will be outcompeted for nutrients. You’ll be eating a lot of corn and rice, not so much in the way of fruits and nuts anymore. So although it is temporarily good that plants increase in productivity, it is only a temporary pushoff for a much larger problem. If you are curious, look up the Ehlringer group at the University of Utah for this research. Now that I’ve flamed you. Let me say that I agree that science does upon ocassion interfere with politics quite inappropriately. Scientists should not dictate political policy, but should provide lawmakers with the most accurate and up to date research and their likely implications. The lawmakers should make these policy decisions, but that doesn’t mean scientists can’t vote or write their elected representatives like everyone else. Also means that we can lobby them in much the same way. Hey, buisnesses and churches do it, why can’t we? I saw a number of comments concerning modeling earlier in this blog. Quite appropriately someone mentioned the strawman argument using stock forcasting. This is a very poor comparison with scientific modeling which is based on a set of rigorously determined physical rules which stock forcasting is not. Scientists use models to get a feeling for how a system works and an attempt to predict or forcast some consequence. Although our models inherently include assumptions that are not true everywhere, they often approximate the average. Models also may lack some of the physics of the system, which is certainly true of the climate. Some of the physics that is not included changes the result very little. Other excluded effects have the potential to significantly change the results, but if we train a model on existing data, it is unlikely that our predictions will be extremely far off the mark. Although “unlikely” suggests a possibility to the layman, this often means scientists are pretty certain it won’t happen. Let me give a simple example. If a weather forcaster says that the temperature tomorrow is going to be 72 degrees based on today’s models and the actual temperature is 75 degrees, were his/her models bad? Probably not, there is always some uncertainty, but if he is within a few degrees just about everyday, then his/her models are pretty good. If (s)he predicts the temperature will be 40 degrees when in actuality it is 75, then his/her models are poor and (s)he should be shipped off to Siberia. I doubt that any scientist will stand up and quibble with someone who predicts that the temperature tomorrow will be 72 when the other says when he predicts 76. So if a scientist says the temperature of the globe will warm and (s)he says how much, ask him/her what others think it will be and what his uncertainty is. Why do scientists put so much stock in models? It is only when they can reliably reproduce the general patterns we see in nature. BTW – What exactly is non-thermal conductivity? Either you are mistaken in your terminalogy or you just pulled that one out of your … |
dhasterok – thank you!!!! Nice comment with real science. |
Wow, I’ve been contemplating all day how to respond to the fake science Jonathan is attempting to forward as truth. Thanks!!! Jonathan, I was curious about your claim that no articles have been written about global warming in antarctica in the last five years. Using Google Scholar to guesstimate the number of articles written in the last year on antarctica and global warming (searching using those two terms) I came up with 1,100 articles published between 2006 and 2007. Between 2005 and 2006, 1,460 articles were published; 1,510 articles come up for the period between 2004 and 2005; 1,280 between 2003 and 2004; 1,180 from 2002 to 2003; and 970 between 2001 and 2002. I hardly think this is evidence that people are avoiding the topics of global warming and Antarctica. I’d like to know exactly where you learned that water is a greenhouse gas. Was it, by chance, in an elementary textbook? I’m glad you agree that water is a greenhouse gas; it is, indeed, the most plentiful in the atmosphere and thus the largest contributor to the greenhouse effect. If not for water vapor in the atmosphere, the planet would be uninhabitably cold, and probably Mars-like. In fact, many scientists, myself included are very interested in the feedback between temperature and water vapor. As temperatures increase it is expected there will be more water vapor in the air, which will again increase the amount of solar energy captured by the atmosphere, creating a positive feedback loop. Increased cloud cover is expected to act as a “brake” on this feedback, as I understand it. This feedback has some interesting implications for drought frequency and intensity and for severe weather patterns. I have a more thorough treatment of why we scientists think global warming is occuring and why we think it’s anthropogenic (human caused) here for those who are interested in the actual science. |
You guys are awesome. I ♥ scientists. |
That funny line was supposed to be a heart shape. |
I have not seen any scientific study that points directly to any hard conclusive data that demonstrate that CO and CO2 are the primary greenhouse gases causing global warming and that by singling out CO and CO2 we can completely eliminate any and all problems associated with global warming. If anyone knows of such a study – please supply the links. Proof that H2O is the major contributor to global warming and everyone can observe this proof. If we are to visit a desert (low humidity) during the hot summertime we will find the days hot and the nights cool. This is because of the lack of the global warming greenhouse gas H2O. If however we are to visit a tropical area or area of high moisture (high humidity) we will find both hot days and hot nights (less change between day and night). This is because of the presents of the greenhouse gas H2O. I submit this will be experienced even with or without the higher concentrations of CO and CO2 that is making all the fuss. kristine N: Since you do not like me and my post please read dhasterok’s post #180 since you like him and his posts; that H2O is a greenhouse gas that absorbs infrared radiation. Sorry dhasterok I apologize for my spelling of absorb. As for Antarctica: it was discovered a few years back that there is a giant volcano (world’s second largest next to Yellowstone) that is active and heating up the area in preparation for an eruption. It is estimated that when it erupts (sometime within the next 500 years – a very short time geologically which means anytime) that it could likely melt enough of the southern polar ice to raise the oceans from 12 to 20 feet. This will cause 80% of the world’s human population to find new homes. It will flood over 90% of the world’s shipping ports, over 90% of the world oil refineries and over half the nuclear facilities. But this would not be a real problem right?? It will also change the salinity of the ocean more that what is claimed in current models of global warming and thus be far more the problem. But who cares??? Global warming with CO and CO2 is much more the “Political†issue. So try to find a link about the volcano in Antarctica – good luck. I obtained my degree in Math and minor in Physics from Brigham Young University. Jonathan |
I want to say something. As a high school graduate, I’m frustrated by the contradicting assertions of scientists. One “expert” has all kinds of facts and statistics to back up her or his position, which directly contradicts the other “expert’s” position, which is backed up by facts and statistics. Some people are convinced one way, others, the other. Even if you guys dumbed it down, both arguments are convincing. I have no clue what to believe. |
Jonathan M–you are indeed correct that it is the absence of water in the desert air that causes it to rapidly cool at night, while more humid air retains its heat through the night. However, this is not the greenhouse effect. Instead, it is a consequence of the higher heat capacity of H2O relative to other atmospheric gases. If you will recall, the amount of heat energy released at night per unit mass is equal to the heat capacity times change in temperature (remember, q/m=c*(Tf-Ti), where q is heat energy, m is mass, c is heat capacity, Tf is final temperature, and Ti is initial temperature). Because the heat capacity (c) of H2O is much larger than the heat capacity of CO2 the amount of heat stored by H2O is greater. For a similar amount of heat loss overnight, the associated temperature change is much less when the air is humid. This is a separate property than the absorption of IR by CO2. annegb–sorry for your confusion. With regard to major issues like global warming, the media gives equal time to both “experts.” Oftentimes on these sorts of issues one is an expert and one has a political agenda. It is difficult for laymen to distinguish between the two “experts” and the media does little to distinguis between the two. The absolute best thing you can do is to keep asking questions and try and seek out the learning you need to understand. For issues like global warming there’s typically a very large scientific consensus. Even some so-called “climate skeptics” (for example John Christy) agree that climate change is happening and that humans are the cause. Those among the majority are quibbling over the details, such as exactly how much it has warmed, exactly how much it will warm in the future, and what the implications of this warming will be. |
“kristine N: Since you do not like me and my post please read dhasterok’s post #180 since you like him and his posts” So, is this the bloggernacle equivalent of my favorite schoolyard insult, “well if you like him so much, why don’t you marry him?” “I have not seen any scientific study that points directly to any hard conclusive data that demonstrate that CO and CO2 are the primary greenhouse gases causing global warming and that by singling out CO and CO2 we can completely eliminate any and all problems associated with global warming. If anyone knows of such a study – please supply the links.” First of all, I’m not sure why you keep bringing in CO. Nobody is mentioning it as a greenhouse gas except you. Second, your statement creates an impossibly high bar for evidence. It’s the equivalent of tobacco companies claiming that because not everyone who smokes gets cancer, tobacco isn’t the cause. We have a mechanism for CO2 warming the atmosphere (explained in detail by dhasterok) and we see a very good correlation between temperature and CO2 concentrations over the last 400,000 years (see this figure). |
Kristine N- Dave Hickey tells a story about how he discovered the impotence of contextual irony in the face of virtue. In the case of JM, substitute some word other that virtue. The guy doesn’t even know when he’s being teased. Best to ignore him. I enjoyed both of your posts on BCC. I wish people didn’t imagine the whole issue of global warming was so esoteric. Anyone willing to sit down a read a little bit can at least acquaint themselves with the basics. Thank you for bringing the debate to a broader audience. |
Greenhouse gas Greenhouse gases are components of the atmosphere that contribute to the greenhouse effect. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. I just wanted to point out that water vapor is a greenhouse gas – is more abundant in the atmosphere than CO2 and will hold mor heat than CO2 and that both accure naturally – without man Jonathan |
Jonathan M, I am so happy to hear you have come around and now agree that greenhouse gases exist, and that water, CO2, methane, nitrous oxide, and ozone all act as greenhouse gases. I’m glad to see you are paying attention to the arguments dhasterok and I are putting forward. |
dhasterok: I saw a number of comments concerning modeling earlier in this blog. Quite appropriately someone mentioned the strawman argument using stock forcasting. Yes. Those would be mine. I’m wondering if you actually read them, or if you only saw them. dhasterok: Quite appropriately someone mentioned the strawman argument using stock forcasting. This is a very poor comparison with scientific modeling which is based on a set of rigorously determined physical rules which stock forcasting is not. Two logical flaws in this assertion: 1. You’re begging the question; viz., whether or not there are rigorously determined rules behind long term, parameterized climate models. You can’t just identify a mechanism for CO2 warming the atmosphere in a comparatively closed system, and then extrapolate indefinitely in an open system. Just to start with, it ignores the question of thresholds and diminishing returns as well as emergent dependent and countervailing factors and out-and-out externalities. Moreover, data gathered from historical analysis of CO2 (and other gas) quantities presents additional challenges. It is incumbent on the scientist to demonstrate that (say) data collected for some certain period in which previous warming occurred isn’t merely non-causal epiphenomena. 2. You’re arguing beside the point. I’ve said in an earlier comment that if the notion of stock models makes you uncomfortable, then you’re free to simply substitute the appropriate climatology verbiage in my comment #113. The stock market example is not a strawman, because it demonstrates a very general principle that is not specific to securities markets; viz., that you can only test models by comparing them to data sets that are different from the known data set that they were devised to explain — otherwise you’ve no predictive validity at all, just after-the-fact explanations and auxiliary hypotheses. I find it fascinating that self-proclaimed scientists are always among the least likely to successfully make or identify generalizations on their own. This principle in my comment #113 was practically a gimme, because I as much as said that it was an instance of a broader problem. I’ll leave aside the fact that you evidently don’t know much about how securities markets work, and I’ll give you a quick tip on how to approach arguments logically: If you’re going to quibble with the application of some general principle to anthropogenic global warming, it won’t due to merely say that it’s different from stock markets (even if I say that they aren’t). dhasterok: Let me give a simple example. If a weather forecaster says… Local weather forecasting bears no similarity to long range global climate models. That’s why there’s no plausible climate model that can predict both global warming and the temperature and humidity on (say) July 4th 2010. The attempts I encounter to prove that climate models are correct remind me of Hegel’s proof that there are only 7 planets. As luck would have it, the 8th planet was discovered just before Hegel’s proof went to press, giving him the opportunity to revise it accordingly (which is, by the way, another instance of reasoning that demonstrates the error outlined in the general principle described in my comment #113). Have you ever taken the time to compare the claims made by climate models from 10 years ago to the global temperatures today? How many years have such models correctly predicted the global temperature? Is there any model that has been right every year? What do the models predict happening if humans decrease their greenhouse gas emissions and over what span of time? These are the operative questions. Whenever I’ve sought answers to them in the past, I get lengthy, convoluted attempts to explain why the predictive accuracy of the models doesn’t actually matter (only not in so many words). You claim to be studying science in a field related to this. What do you have to say? Look, it’s nice of you to login to help kristine N and Devyn. It’s obvious that you know a lot of scientific facts and words. But you don’t seem to know a whole heck of a lot about logic or about how science actually works. Furthermore, nobody here has even tried to refute my statement in comment 111 that “Our cloud microphysics and ice physics are among the worst of those on any habitable planet in the Intergalactic Confederation.” |
But, you know, David, we are having weird weather locally. That scripture about not being able to tell the seasons certainly applies in southern Utah. We’ve had a drought for six/seven years and it will be positively balmy in January. Until this year, when we are having real winter. Everyone is loving it, too, because there is some relief when Mother Nature behaves predictably. But truly, it is so hot here in the summer we have to ration water and our gardens are failing. It is hard to tell the seasons from the trees. |
annegb, We had summers like that in the Washington, DC area when I was growing up. Record setting highs with droughts with low reservoir levels. Since we moved to Boston, the last two years have been the first two where there hasn’t been either record colds or record snow-falls — everyone told me that I moved to Boston at the wrong time, because winters weren’t usually that severe. This winter in Boston, it was in the high sixties in early January, but this February is no different from any other. We only see a few dozen examples of each season, so it’s not like we actually have a set of anecdotal experiences large enough to make reasonable extrapolations about global or historical weather patterns. Plus, most of the worlds climate systems cover oceans. |
But four years ago, I flew to Casper, Wyoming in February to help take care of my mom and I sat by a woman from Montana. I said something about our drought and she said they’d also had a drought. She said it was that whole area from north to south. Are you saying there are always these extremes in weather? I’m not so sure. Well, heat bothers me more than cold. I’d rather have the blizzards. Although, I must say, the mud is getting to me now. |
Correlation and Causality Feedbacks and Forcings In science we talk about feedbacks and forcings. Forcings are the physical phenomena that drive a system to change and are determined or estimated by experiment. For example, greenhouse warming is a process related to increasing the concentration infra-red absorbing gases (CO2, H2O, CH4, etc.). We can demonstrate in a laboratory that CO2 is a gas that can slow the transmission of heat by absorbing infra-red radiation and therefore slow cooling. Or in the case of the Earth, which is constantly under a heat lamp (i.e. the Sun) that a higher equilibrium temperature will be reached as a result of increased CO2 in the atmosphere. The greenhouse phenomena, including CO2 and all other greenhouse gases, is the most important climate forcing, besides solar input, in the atmosphere. Feedbacks are processes that occur when you change a particular forcing and can be positive or negative. Suppose the Earth’s glaciers are growing. If you increase the extent of the glaciers, you raise the albedo of the planet and reflect more incoming radiation, thereby cooling the planet. Because the planet has cooled, the glaciers grow larger, which in turn raises the effective albedo some more and the planet cools more… and glaciers grow and the planet cools and… you get the point. This is a negative feedback. The climate system has many of these. Some try to warm and some try to cool, this is what provides some of the “stability” to the system, preventing it from spiraling out of control. Read about the atmosphere of Venus to see what happens in an out of control greenhouse effect. Climate modelers try to account for as many of those forcings and feedbacks in their models as possible. These are the physical foundations of these models. Next all we need is an initial condition, that is, what are the current levels of these forcings. Greenhouse gases and Temperature Economic vs. Climate Models In 113 you state that “for any given state of affairs, there are an indefinite number of theoretical explanations that can adequately explain it.” This is true of the climate system as well. However, we can measure the current state of the climate system and most of the variables that go into it. If we have done this correctly, then one can use it as an initial condition from which to begin the model, assuming of course we understand enough of the physics. These models are then tested on existing data (as you state) so that we can gauge how well our model may be working before accepting them as predictive tools. Now I said we could measure the initial state of the system. We have significant uncertainty in those measurements and the mesurements of the initial forcings and therefore our models are imperfect. So how do we quantify these uncertainties? Since we know the uncertainty we can use Monte Carlo techniques to try and estimate our uncertanties in the initial state. If our simulation does not fit what we see, then it is tossed and we ignore it because it is inherently broken. If we get a simulation that approximates reality over the training period, then it is a possibility (one of your “indefinite number” above). When we are done, we may have a better estimate of the uncertainty in our initial state and forcings. What we have done is significantly narrowed the field to those which may be possible. If we take each one of the possible simulations and try to predict the future, we can develop a range of possibilities for the future climate. From this ensample of models we have a bounded estimate of future temperatures. Our result could predict cooling just as easily as warming if the initial conditions warranted such, however, they do not. To generate the models to predict the future climate system, we develop senarios for future forcings such as CO2 increases or stabilization or decrease. They offer us a possible glimpse into the future to what our given our current and future choices will mean. I’ll also point out now that regardless of what we do with our CO2 emissions, the planet will continue to warm based on current models. This is because we have built up that much ‘inertia’ (if you like) into the system. In 127 you state that “Anaxemander theorized that a force akin to gravity kept the Earth in place and Democritus invented the notion of the atom.” Yes they did, however, I might point out that Democritus did not realize that there were sub-atomic particles that make up the elements which they could not prove existed. And that Anaxemander did not develop a physical model for gravity that could be tested as Newton had. His model was of course derived from observations contrary to what you say… His argument essentially went something like this “If I throw something into the air it always comes down again and never floats into the heavens.” I might also point out that we still don’t really know what causes gravity, only that there is a force we must reckon with. By the way, there is another explanation for the force associated with gravity. Although I’m still partial to Newton’s formulation. You also state, “There’s no reason a scientific theory couldn’t originate in a dream…”, which I agree with. Many great and wonderful thoughts can come while sleeping. In fact, I know a scientist (Dr. Emmit Brown) that came up with a vision of a time travel device after he fell and hit his head on a toilet bowl. However, I would change your word from ‘theory’ to ‘hypothesis’ as it must be rigorously tested first. There is a big difference between natural philosophy (or logical reasoning about observations of nature) and scientific inquiry (testing hypotheses derived from our understanding of the physical laws). Philosophical arguments are concerned only with the why, while scientific arguments are concerned with both the how as well as the why. Good luck trying to come up with a number using philosophy. Climate models may have a large degree of uncerainty, but they all indicate significant warming for the future, something which should be alarming to most of us. If you don’t believe that we should care then I’ve got two words for you… SEA LEVEL! You comment that: “you can only test models by comparing them to data sets that are different from the known data set that they were devised to explain.” If you can’t reproduce what you already see, then how can you determine that your model really works? And you claim that I don’t understand science. |
In Dallas, where I was raised, I used to mark the coming of spring by the blooming of the redbuds. It always happened the week of my birthday without fail. For the past five years they have been blooming earlier and earlier. In Austin (which is suposed to be only two weeks ahead of Dallas) I have seen them bloom in December and January. Also several plant species are are creeping north, ball moss (a bromeliad, related to pineapples), is well established in Dallas now. My parents have coma sprouting in their back yard (it was absent my entire childhood). And Jerusalem thorn (native to south Texas, like coma) is becoming a veritable weed in Austin. This year’s freaky weather in the US (and probably here in Thailand, where we’ve had record cold) is due to El Niño. For signs of long term climate change I’d pay attention to the plants. |
nofolete–those are some great observations. We talked about that exact thing last week here in our climate seminar, though we focused on insects (especially butterflies and moths) and, of course, mammals. very timely. That actually brings up somewhat of a caveat for comments I’ve made (not necessarily here). It’s expected that climate change, especially abrupt climate change, will lead to species turnover (extinction of some species and expansion of others). The probability for extinction is much higher for animals than it is for plants, though it should also be noted the expected “lifetime” of a species (the approximate amount of time that species successfully reproduces) tends to be much lower for animals than plants. So, it’s fairly probable polar bears will go extinct, or hybridize with grizzlies, but it’s likely most plant species (or at least genera) will survive, though in different ranges. |
I love scientists!! Thanks for the input guys/gals, I think that you have brought forth some very compelling arguments. Here in New England scientists are seeing a lot of a type of beetle (I believe) that kills hemlock trees. The long winters use to kill it, but now it does not freeze long enough to kill off the beetles. While plants may survive, I think the only animals that may be around will be houseflies, rats, cockroaches and such. Yes, humans in some form will survive too as we are of the same ilk as the aforementioned critters. |
Yep, weed species will do fine. |
Yep, “weed” species will do fine. Look at how well coyotes (formerly limited to the great plains, and generally under 20 pounds) are taking over former wolf habitat–they are also getting huge, and moving into cities. Parts of Texas and the south are starting to look like an Asian melting pot–china berries and tallow tree surrounded by an under-story of ligustrums and nandinas, out competing all the native flora. Species that tolerate/thrive in our presence have a distinct competitive advantage. Like you say, Devyn, a world of roaches and rats. |
We have a similar problem with bark beetles in the west that kill pine, fir and spruce trees. Kind of a blight when you hike through a forest of dead trees. Not to mention the fire hazard. In the west it isn’t the cold weather that no longer kills beetles in the winter. That’s what I once thought too, but my biologist friends have informed me that it is because the temperature stays warm long enough for two generations to go through their full life cycle. The trees can withstand one generation a year, but not two. It may actually be the same thing in the east. |
dhasterok: However, if it can be shown that there is a physical link between two phenomena,
such as CO2 and temperature, then there is a causal relationship. Wrong again, dhasterok. Causal patterns require not just a link, but also a baseline set of conditions that must exist for the link to be efficacious. Think of it this way: You can say that putting a quarter into a pay phone causes it to be ready for your phone call. This assumes a baseline condition that includes a currency system for coins and a telephone network. Moreover, putting 2 quarters in the phone won’t necessarily make it ready for two calls; e.g., try putting both the quarters in at once. There’s an entire body of literature on how causes work, including those who (following Hume and many quantum physicists) do not believe that causes are necessarily real and don’t see them as an important part of science. You’ll do much better not to say things like, “This is the principle of causality” when you’re (a) wrong, and (b) unable to demonstrate that you have a good grasp on the concept. dhasterok: “Diminishing returns” — You must be an economist. Uh, no. I’m not an economist. I have no real training in economics. In fact, I have no very substantial education background in any field. That said, diminishing returns is a mathematical pattern that describes 2 thresholds. The pattern is one consisting of three phases (divided by the 2 thresholds): (a) an initial phase in which each additional unit of something has a disproportionate positive effect, (b) a leveling-off phase where each additional unit has less and less of a positive effect, and (c) a phase in which each additional unit has a negative effect. An easy example pulled from civil engineering is steel dowels in concrete pillars. At first, each additional dowel will add a disproportionate amount of stability to the pillar (e.g., adding a third dowel results in a more than 50% increases in stability). At some point, the stability of the pillar is not impacted at all by the dowel (e.g., adding the 51st dowel does not add 2% stability). At some later point, adding dowels is counter-productive, so that adding additional dowels to the construction of the pillar makes it less stable. (The actual numbers that determine these thresholds depend on a number of factors, but this illustrates the pattern.) One can also describe the way that water expands below 39 degrees Fahrenheit by saying that removing heat from fresh water in order to make it more dense has diminishing returns. This is a very common pattern, and it is of a categorically different type than feedback and forcings. dhasterok: Climate modelers try to account for as many of those forcings and feedbacks in their models as possible. Unless you see me as accusing them of relying on (say) tea leaves to create models, I can’t see how this is relevant. Nor do your ruminations about feedback answer anything in my comment #113. dhasterok: Economic and climate models are not analogous…. First of all, as I noted earlier, if you wish to disagree with me on whether some pattern applies to climate models, you fail to address the point when you assert that climate models are different from some other kind of model. Second, I’ve never claimed that climate models are analogous to economic models. The principle I describe in my comment #113 applies to all models, and it’s not a controversial approach. I don’t know the first thing about specific economic models and their relationship to known vs. unknown data. (And just to clarify: securities market models are not economic models.) dhasterok: In 113 you state that “for any given state of affairs, there are an indefinite number of theoretical explanations that can adequately explain it.” This is true of the climate system as well. Yes. In fact the way that I phrased my statement entailed that it must be. That’s an accepted formulation of the Quine-Duhem thesis. dhasterok: These models are then tested on existing data (as you state) so that we can gauge how well our model may be working before accepting them as predictive tools. You’ve failed to demonstrate how designing something to explain a known data set has any bearing on its ability to predict unknown data sets. Thus, you beg the question. You simply assume that the existing data is a good gauge of predictability, when that’s the idea that I’ve shown to be mistaken in the first place. dhasterok: Our result could predict cooling just as easily as warming if the initial conditions warranted such, however, they do not. This is not a surprising result. It likely originates in inescapable bias created by the fact that we know much, much more about the mechanisms by which the earth is warmed than those mechanisms by which it is cooled. dhasterok: I might point out that Democritus did not realize that there were sub-atomic particles that make up the elements which they could not prove existed. Yes. It’s easy to point out the flaws of the scientists of yesteryear. They’re no more wrong than Copernicus, who thought that the earth revolved around the sun in a circular orbit. Or Gallileo, who was wrong about optics. Or Newton, who still believed in ether. Or Darwin, who believed in the inheritance of acquired traits. 100 years from now, we’ll be able to say the same sorts of things about today’s prominent scientists. dhasterok: You also state, “There’s no reason a scientific theory couldn’t originate in a dream…”, which I agree with. Many great and wonderful thoughts can come while sleeping. In fact, I know a scientist (Dr. Emmit Brown) that came up with a vision of a time travel device after he fell and hit his head on a toilet bowl. However, I would change your word from ‘theory’ to ‘hypothesis’ as it must be rigorously tested first. Actually, Emit Brown came up with the idea for the flux capacitor that way, which was a primary component of a time travel device, but it was not itself a time-travel device. On this point, you’re too pre-occupied with verbiage. If you’re going to quibble about words for rhetorical effect, you should at least offer valid criticisms. Specifically, since theories originate in hypotheses, your attempted correction results in a statement that is materially equivalent the statement you criticize. dhasterok: There is a big difference between natural philosophy (or logical reasoning about observations of nature) and scientific inquiry (testing hypotheses derived from our understanding of the physical laws). Philosophical arguments are concerned only with the why, while scientific arguments are concerned with both the how as well as the why. Good luck trying to come up with a number using philosophy. First of all, you can’t test hypotheses derived from our understanding without making observations about nature. Observations made in labs are no less observations made of nature than the careful measurements that Kepler accumulated. Second, philosophical arguments are not concerned with “the why.” They’re usually concerned with the structure of the theory as such, its relationship to other theories, and its implications. Third, why-questions can only be answered from within a frame of reference. You can ask, “Why does a computer chess program make this move?” In a programming class, the correct answer likely relates to specific computer instructions. In an electronics class, correct answer may relate to the interaction of the chips as observable with a logic probe. In a chess class, the correct answer likely relates to a certain chess strategy. Why-questions exist within a theoretical framework, but there is no way to arbitrate the why-claims of competing frameworks. Thus, there is a classical physical explanation for why balls bounce off of walls and a quantum physical explanation for why balls bounce off of walls. But the question of which one is really the answer is external to both frameworks. Since such a question must be internal to some kind of meta-framework that envelopes both of quantum and classical. Whenever there are competing meta-frameworks, such external questions are, in some sense, pointless. (FYI, this is the type of philosophical approach to science that I describe in the preceding point.) Fourth, the unifying factor among the different arms of science is a set of tools that facilitate critical thinking about ideas. The experimental process is one of the more important ones. So is deductive reasoning. It’s mistaken to claim that science is about induction or is about experimental procedure or what have you. That’s like saying that driving is about steering or about hitting the breaks or about pushing on the accelerator. dhasterok: You comment that: “you can only test models by comparing them to data sets that are different from the known data set that they were devised to explain.†If you can’t reproduce what you already see, then how can you determine that your model really works? And you claim that I don’t understand science. This is a very strange question. Science doesn’t care what you already see. In fact, science is often successful at showing that what you think you see is wrong. But if I have these sets of data A and B, and I devise a hypothesis to explain them, reasoning that my theory is valuable based on the fact that it explains sets A and B is circular. I want to test my hypothesis using some other set of data that was unknown at the time that I devised my hypothesis. Again, you’ve failed to demonstrate any serious comprehension about how science works. Plus, you still haven’t shown how the principle that I demonstrate in my comment #113 is flawed. And your answer to my questions at the end of my comment #193 are exactly as I predicted they would be. |
how long does it take for you guys to type this stuff up? |
A friend of mine suggested I take a look at this discussion and I can’t believe some of the stuff I am reading. DKL – Give me a break. You speak in philosophical circles and clearly, CLEARLY, do not understand science. Sure, you have a great grasp on vocabulary and the philisophy of science, but that doesn’t imply you understand anything but those topics. Sure, this may seem to be somewhat personal, but you are exactly like the “Bible Bashers” I met while tracting. All talk, “all knowing,” and not open to the truth. This discussion has moved far from where it originated, which was “Why have Mormon leaders been so silent on the issue? Why are so many Mormons not concerned about it? What should we as Mormons be doing in our personal lives to reduce our contribution to the problem?” |
anon, I type really fast. That last one took on the order of 25 minutes. I typed it into a text editor and then pasted it into here. Mike, you’ll have to forgive me for thinking that your comment is pretty lame. Not only does it fail to leave the slightest indication that you understand how science works, but it fails to identify anything I’ve said that justifies your assertions. Let’s look at some of the areas that I’ve addressed in concrete and non-controversial terms: 1. How causation works I invite you to take issue with anything that I’ve said in these areas. I also invite you to identify a single “philosophical circle” that I speak in. Nothing that I’ve had to say about the above issues represents anything original or controversial. In fact, the position that rejects everything I’ve said in this regard would be quite controversial indeed. It’s awfully easy to just come in and say of someone that they “clearly, CLEARY, do not understand science.” This approach is resembles the approach of Evangilicals who simply dismiss Mormon Bible-based claims by saying, “you clearly, CLEARLY, do not understand the Bible” as though saying it makes it so. If everything I’ve said is so palpably ridiculous, then show us what you’ve got. |
Global warming is real. Humans have made it worse. I really don’t know why people argue that things are not getting worse when the evidence is all there, bright and clear as the sun that heats this earth itself. I don’t think we’re trying to assess blame here, but we as humans do need to change our lifestyle if we are really to take care of this earth of ours, as is our charge. When God commanded Adam and Eve to “be fruitful, multiply and replenish the earth“, I think He meant it. How do we replenish the earth when we pollute it with our carbon monoxides that are useless on this planet? Plants can’t use carbon monoxides. They need carbon dioxides. Humans obviously die of carbon monoxide. Just why is the “other side” of this debate so vociferous in defending our glutenous lifestyle? |
Mike, I don’t know. Give me something tangible I can apply in my life, that’s reasonable and valid. |
annegb et al- Here is a US Department of Energy web page listing green energy resources in Utah: http://www.eere.energy.gov/greenpower/buying/buying_power.shtml?state=UT This next page lists ten things you can do personally to reduce green house gases and energy usage. Several of the items mentioned are already being implemented by the church in our buildings, such as switching the light bulbs, and are along the line of advise given at the church run providentliving.org. |
DKL You say “In fact, I have no very substantial education background in any field.”–perhaps then you are just hopelessly uninformed and try to use a lot of big words and terms to try and quiet others into submission. Dimishing returns is an economic principle. In science, when some behavior “plateaus” or “levels-off” it is asymptotic behavior. Although this may be similar to the economic principle on a general level, they mean two different things. It is unfortunate that your example, feeding coins to a payphone, to dispute my knowledge of causality is in fact a causal relationship. You said that you first have to assume that there is a system of currency and networks. And I’ll tell you that there is, and similarly in physics there is a system which approximates the mathematical box we have tried to fit within it. You may be right that putting in two quarters does not make it ready for two calls. But the system works on a well defined rule. If you give a payphone coins (not pennies) worth above a threshold, that being a $0.25 (I believe the actual going rate for most is now $0.50 or two quarters), you will be able to place a call. Placing the coins into the phone triggers responses that sorts them, counts them and perhaps many other actions. But there is a causal relationship that exists between placing money in a payphone and the ability to make a call, nevermind that there are 12 steps inbetween or that there may be other rules that allow you to make calls. An aside from PG… You state “philosophical arguments are not concerned with ‘the why.’” Do you remember the famous final exam question and only response worthy of an ‘A’? Q. Why? A. Why not? A ‘why’ question is one that seeks to find the underlying reason some phenomena happens. ‘How’ questions are ones that ask by what means some phenomena happens. Many of your arguments stem from philosophy. Which I might add is not science. They operate on many difference premises. Philosophy works on the foundation that anything may be described using logical arguments derived from the mind. Following logical arguments occasionally leads one to the wrong conclusion, or may result in the correct conclusion from provably false assumptions (see Kepler’s proof of elliptical orbits). As a simple example I will take the powers of zero (I first came across this in R. Kaplan’s book “The Nothing that is”). Lets try to use logic and the properties of exponents to decide the answer. If I take a number, lets say ’5′, and raise it to the first power (5^1), I get the result 5. If I were to now do 5^2, I get 5*5 or 25. If I wanted to do 5^7 then I would have 5*5*5*5*5*5*5. So you see that when you raise a number to an exponent, then it is that number multiplied that many times, but what about 5^0. Ok, so now we need to figure out what a number raised to zero means. So lets look at negative exponents. 5^-1, which we all know means 1/5 and likewise 5^-2 is 1/(5*5) or 1/25, and we can show that a number ‘a’ to a negative power ‘-n’ is 1/a^n. So how does this help us solve 5^0? If we divide 5^4/5^2 this is 5*5*5*5/(5*5), which I am sure you will agree is 5*5. So, 5^4/5^2 = 5^2. If we then have 5^2/5^2, which is the same as 5^0 (since we can subtract the exponents) and 5^2/5^2 = 1 so must 5^0. So any number a^0 must be 1. Therefore if we extend our rule to 0, 0^0 should be 1. So let us take another try at finding out what 0^0 is. This time lets use fractional exponents. We’ve shown that 5^2 = 5*5, then what is 5^0.5? Well we know that it is the root of a number. 5^0.5 = 2.236 and if we do it again, 5^0.333 = 1.709. So lets do the same thing with 0. 0^2 = 0, 0^1 = 0, 0^0.5 = 0… as we keep doing this, logic dictates that the answer to 0^0 should be 0. Great, so using perfectly logical approaches to find 0 in two different ways we have shown that 0^0 is both 1 and 0. So again logic must dictate a paradox in our math system that 0 = 1. Do you follow? That’s a real problem in standard algebras (turns out the answer is 1). If that was confusing, then try to figure out what should 0/0 be? What is described above is a philosophical argument, but not science. The Quine-Duhem thesis that you seem so fond of may state that there are an indefinite number of possible explanations to describe an observation, but in science we can often place constraints on which are likely. All evidence supporting theories are inherently undetermined, which is why we spend so much time trying to disprove them. If they survive the test, then they get promoted to the next level and are attacked once again. The more theories we can show are false, the smaller our field of possible theories become. No theory can be entirely proven, only falsified. This is the basis of scientific philosophy today (see below about Goedel). Despite the fact that multiple theories may remain that describe a given phenomena, we need some other measure of discrimination. Although it is not really based in logic, we use Occam’s razor, that the simplist explanation is the best, to select what we feel is the most likely. Since you like philosophy so much, I’ll bring up another philosophical point, one which bridges the gap between science (I’m using the term loosly here since I am including mathematics as a science) and philosophy. Goedel’s incompleteness theorems, of which there are two, state: 1. For any consistent formal theory that proves basic arithmetical truths, an arithmetical statement that is true but not provable in the theory can be constructed. That is, any theory capable of expressing elementary arithmetic cannot be both consistent and complete. and 2. For any formal theory T including basic arithmetical truths and also certain truths about formal provability, T includes a statement of its own consistency if and only if T is inconsistent. So what do these mean? Well, I think that they are pretty plain when translated from German into English: any formal system that has a set of formal rules is incomplete and self-consistent (which is the math we use for science) or complete and inconsistent (that is, one fundamental rule can contradict another). Which means that there are things that cannot be proven with math. Physics is derived from math and therefore must be incomplete (from 1) or inconsistent (from 2). We (scientists in general) choose the former. So we can’t prove everything with math. Does this mean that we can’t say anything about our natural world? No. In fact we can still say a great deal about our natural world and I’m probably not articulate enough to make an argument why. “Science doesn’t care what you already see. In fact, science is often successful at showing that what you think you see is wrong.” To the contrary, science most certainly does care about what we see, and how it happens. If science shows that what we think we see is wrong, then we saw the wrong thing in the first place and identified our error by a set of new (correct!) observations. The new hypothesis is then advanced which describes what we (now) see. See how circular this is. If we observe something, we develop a hypothesis and test it; if we find that we were wrong (from a new set of tests), we modify the hypothesis or come up with a new one. When we are satisfied that we are very close, we call it a theory. We then modify the theory as needed. If the theory gets too many modifications, then we toss it and go back to the drawing board. All tested by observations–what we see. There are many philosophical texts and hypotheses regarding science, and we both have mentioned a few. Although each may have a grain of truth to them, they do not and cannot encompass the full flavor of science and how it is done or what it seeks to discover. Using them as arguments to refute global warming is no more than jaw flapping that doesn’t address the issues at hand. Try and be more scientific in your approach if you wish to say that global climate models are wrong. Now I’ll address what you pass-off as scientific arguements… “dhasterok: Our result could predict cooling just as easily as warming if the initial conditions warranted such, however, they do not. This is not a surprising result. It likely originates in inescapable bias created by the fact that we know much, much more about the mechanisms by which the Earth is warmed than those mechanisms by which it is cooled.” [Note that I capitalized Earth in the above sentence; see my previous posts for why.] Not true in the least; we know a great deal about first and second order (and possibly some third order) mechanisms by which the Earth warms and cools. You are assuming that because we think the Earth is warming we understand more about warming mechanisms. However, a great deal of research has gone into understanding the “Snowball Earth”; a case in which the Earth was once a solid popsicle of ice, how it happened and how the planet could get out of such a situation. Likewise, a great amount of effort has gone into understanding what mechanisms cool the planet in order to try and find a viable solution to cool the planet ourselves and reverse the global warming trend. I agree that if you develop a model from data sets A and B and then use the theory to describe A and/or B that the argument is circular and thus pointless. However, with regards to the climate system, the physics is determined independently of the climate system. We can then use our understanding of the physics and chemistry to make climate models. Then all that is left is finding the initial condition of our system and determining the appropriate initial magnitudes and/or patterns of forcings. These are then input into the models. This is not circular at all. If you think it is circular, then you are missing something and perhaps should go read about how this works before you come back and make more asinine claims. Modern Global Circulation Models (GCMs), as well as regional climate models, are developed from the basic physics, using the finest discretizations we can while keeping compute times to months rather than centuries. The GCMs are “spun up” from an arbitrary initial state for several centuries (to stabilize the grids) until the beginning of the high-resolution climate records (typically ~1500 AD). The next 300-500 years are used for “training” – we tweak the initial state, feedback magnifications, and forcing sensitivities to match the period from 1500-1800 (possibly longer) on a global (or regional) scale. The remaining time to the present is used to check the extrapolation of the model into the future, by comparing the model “instrumental” record with the real instrumental record; good coverage of global temperature, precipitation, etc. is only available from ~1870 forward, with the modern surface coverage starting in the 1940s. Assuming the model run produces a close match to the global/regional climate seen in the instrumental record, the run is continued into the future with assumed forcing changes (“business as usual” CO2 growth, no CO2 growth, solar output variations, etc.). A large ensemble of such runs (with different initial conditions, sensitivities, etc.) then provide an ensemble of the likely (not guaranteed) future history of the Earth’s climate. This is an expansion of what I said in a previous post. You are assuming that you understand the science and how it is performed whereas in fact you seem to know very little about it from what you have written. Or perhaps if you think we all do it incorrectly based on a philosophical basis, then why don’t you try and do some of the research yourself and then tell us what we ‘really’ know. |
annegb–the best thing you personally can do it live a simple life within your means (something we’re counselled to do anyway). Follow nofolete’s suggestions of replacing incandescent with florescent bulbs, turn your thermostat down, insulate your home, especially your attic and your windows, drive less, and support alternative energy sources (including nuclear!) when given the opportunity. Most of the things you can do right now are also things that will save you money in the long run. One of the absolute best things you can do, though, is educate yourself on the science (not the politics!) of global climate change so that you yourself can decide what the best personal and political decisions are. I’d suggest starting with the IPCC report (go to where it says “Download Summary for Policy makers” under Information for Press). It’s likely to be dense, and you’ll probably have more questions at first than understanding (don’t worry–we all feel that way when we start getting into unfamiliar intellectual territory). I’d suggest trying to answer your questions on wikipedia (the link is to their climate change site), Real climate (a site run by a bunch of climate scientists), or I and a few friends are starting a blog we’re calling the breakfast club, and we’d be happy to entertain questions (though I should warn you, the site’s only been up since monday, so there isn’t much there yet). |
dhasterok: perhaps then you are just hopelessly uninformed and try to use a lot of big words and terms to try and quiet others into submission. Indeed. I am, at any rate, smarter than you, so I’d be very careful before I pushed this point very far. dhasterok: Dimishing returns is an economic principle. In science, when some behavior “plateaus” or “levels-off” it is asymptotic behavior. Although this may be similar to the economic principle on a general level, they mean two different things. Diminishing returns is a mathematical pattern that (a) occurs in nature, and (b) is not equivilent to a plateau or a leveling-off. You either did not read what I wrote about it or you did not comprehend it. The pattern that I describe advances and then retreats. It does not approach a limit asymptotically. The question of whether this pattern has any application within economics is altogether irrelevant. One very irritating thing about economists is their tendency to claim that something is economics just because it fits this pattern. Explain how taking heat from water to make it more dense reaches diminishing returns as it approaches 39 degrees and then begins expanding again. Many economists will say that hydrogen bonds are responding to economic laws — as though the fact that they discovered the pattern means that everything that it describes falls within their field of study. Event the Wikipedia article you link to uses an example from nature; viz., the seed example. This fits this pattern that I see more generally in your comments: You don’t know a lot about diminishing returns, but you sense a chance to correct me. So you rush into it, making several barely informed assertions. In this case, it’s especially tedious, because diminishing returns has nothing really to do with this. dhasterok: It is unfortunate that your example, feeding coins to a payphone, to dispute my knowledge of causality is in fact a causal relationship. Since it was my express intent for this to be an example of an actual causal relationship, I’m puzzled that you’d say it’s unfortunate that it actually is an example of a causal relationship. Again, you either failed to read what I wrote, or you failed to grasp it. It’s actually pretty obvious from your response that neither you nor PG understands causation, and your both simply grasping at known properties of science to try to explain it. What makes this obvious is how totally irrelevant the factors are that you mention. For example, you do not understand how baseline conditions work. There’s more to the baseline condition than the system or framework that it occurs in. There are contingencies that must be satisfied within the system for the cause to carry through. For example, with respect to a phone, the system must be reasonably free from certain types of glitches at the moment that I insert the coin; e.g., a nearby utility crew might accidentally cut the line or there may be a scheduled outage, and all of this occurs within the framework of a functioning system. Furthermore, the question of which system you place the payphone into (e.g., a 50 cent vs a 25 cent system or one in which you can make multiple phone calls off of multiple initial insertions) creates a multiplicity of causes. The chess explanation example from my earlier comment can be recycled to show this. What “causes” the computer to make a certain move will be determined by the framework in which the cause is described. This is, in fact, the primary argument against what is known as “modal realism,” which is the fancy term for the idea that causes are actually real. I don’t know who PG is, but she, too, is wide of the mark. My point about causation does not depend on the distinction betwen open and closed systems. Nor does it have anything to do with the fact that science makes progress by separating salient from non-salient factors. As identified above, there are always contingencies within the system. Plus, the decision of which system to apply determines the nature of the resulting causes every bit as much as the causes themselves. dhasterok: Many of your arguments stem from philosophy. Which I might add is not science. This discussion would be more productive if you spent less time criticizing whatever field of interest you’ve lately guessed that I’m attracted to, and more time actually answering my arguments. Regarding “why” questions on final exams, you should pay more attention to philosophy and less attention to urban legends. The zero-power issue is old news. If you believe that there aren’t mutually exclusive problem-solving theories that cover overlapping areas both inside and outside of science, than you are ignorant indeed. There are several answers to 0/0. The systems I work in generally call it NaN. Again: old news. dhasterok: What is described above is a philosophical argument, but not science. So what’s your point? dhasterok: The more theories we can show are false, the smaller our field of possible theories become. No theory can be entirely proven, only falsified. I’ve been complaining all along about the flawed Baconian model of science, and you come to me with falsification as though it’s news? Either you just learned about it today, or you haven’t been reading very carefully (or both). In any case, this is the first accurate and to-the-point thing that you’ve said about science so far in this exchange — and it supports the point that I made in comment 113. Even so, you’re wrong on a few of the details. Specifically, theories never get “promoted.” After they’ve survived enough attempts at being eliminated, the fact that there are an indefinite number of other theories with the same result becomes irrelevant. At that point, the cost involved in ferreting them out becomes prohibitive; entrenchment has real economic value, and a theory in the hand is worth two in the bush. dhasterok: I’ll bring up another philosophical point, one which bridges the gap between science (I’m using the term loosly here since I am including mathematics as a science) and philosophy. Goedel’s incompleteness theorems Nelson Goodman was able to show that it only arises in systems that use discrete numbers as primitives. Furthermore, if you eliminate the set theoretical requirement for some sets to have infinite numbers of members, then you also eliminate Goedel’s theorems, albeit at some cost to mathematical effectiveness. dhastorek: So what do these mean? Well, I think that they are pretty plain when translated from German into English: any formal system that has a set of formal rules is incomplete and self-consistent (which is the math we use for science) or complete and inconsistent (that is, one fundamental rule can contradict another). Wrong again. Your statement here indicates that you don’t understand what constitutes a formal system and what it requires in order to do elementary arithmetic. Quantificational logic systems are exceptionally complex formal systems that can be proven to be both complete and consistent. Introducing set theory (with infinite sets and discrete members) is what upsets the Goedel wagon. Furthermore, Geodel’s theorems only apply to formal systems. Many of science’s conclusions do rely on formal systems, but science itself is not a formal system. In any case, aside from the fact that your mastery of Goedel’s theorems is less than impressive, this discussion of Goedel’s theorems is pointless. If someone points out an out-and-out contradiction in a mathematical proof, it won’t do to say, “Ah, but you forget about Goedel’s theorems!” Nobody justifies actual contradictions by referring to Goedel’s theorems. dhastorek: To the contrary, science most certainly does care about what we see, and how it happens. Wrong again. You’re saying that because the experimental method requires subjective perception to judge the outcome, and because science cares about the outcome, then science cares what you see. That’s simply a non-sequitor. dhastorek: However, with regards to the climate system, the physics is determined independently of the climate system. We can then use our understanding of the physics and chemistry to make climate models. The physics and the chemistry do not determine the makeup or the reliability of the models. They are mere components, and trying to reason from the properties of the components of a system to the properties of the system itself is a form of fallacious reasoning called “the fallacy of composition.” Regarding the construction of GCMs, that may be a fine way to disqualify models to measure against future results to determine their predictive accuracy. But that method only makes predictive accuracy possible — not likely as you assert — for exactly the reasons I describe in comment 113. And you offer no explanation why the approach you describe should be exempted from those reasons. Is it that you believe that the exemption is self-evident? (Coincidentally, the way that you describe the construction of GCMs is identical to the way that most securities market models are put together.) You still haven’t answered any of the questions I put forth about identifying specific models that have proven accurate. I could go on and on, and I have, but close to half of what you’ve written has been given over to irrelevant ramblings disparaging some supposed area of intellectual interest of mine. The rest has been replete with rather obvious fallacies and logical errors (as I’ve pointed out repeatedly) and patent demonstrations that you lack a sufficient background to make educated conversation about the topics that have arisen; you don’t have a strong grasp of causation, philosophy, math, Geodel’s theorem, or even science itself. Given this, its astonishing how shrill you’re willing to get about who knows what as well as how eager you are to take strong stances when you lack the knowledge to back it up or even discuss the topic very clearly. There have been a few commonplace scientific principles that you seem to have a grasp on (like open vs. close systems and science as a simplifier), but even these you mis-apply. |
and the winner is… |
I’ve not been following the thread. But I’d intended to write a post on the Quine-Duhem thesis. It’ll hopefully come out later tonight at my blog – so stay tuned. But I’d disagree with DKL that the Quine-Duhem thesis is conventional wisdom. While I think most are sympathetic to the general problem, the way it is framed is just too radical and universal. A few notes. Duhem’s thesis was limited to physics only and not science in general or logic in general. It’s much more defensible although it has one or two problems. Quine, of course, was defending a general logical assertion. However it is very problematic since it either follows trivially from holism (and thus doesn’t assert much), ignores the ability of induction or other non-deductive rationality to choose between alternative (i.e. ends up being not much different than Hume’s thesis), or else assumes that all ideas are so related they can’t be separated in any way. As I said, I’m actually very sympathetic to the general idea. (Although I find a more useful approach comes from semiotics ala Derrida’s critique which is remarkably similar to Quine) But in practice it doesn’t quite have the far ranging implications some broach for it. |
DKL You say “Indeed. I am, at any rate, smarter than you, so I’d be very careful before I pushed this point very far.” You really are the pompous jack@$$ I thought you were and debating with you may indeed prove pointless. Pointless because you have preconceived notions about science and terminalogy (i.e. definitions) that are unfortunately incorrect. But I’ll point out your glaring misunderstandings once again. You state “Diminishing returns is a mathematical pattern that (a) occurs in nature.” Please provide me a reference to this. From Wikipedia:
I’d like to point out the following statement, “ostensibly a purely economic concept”. It is purely a construct within economics. And as I said they are similar to the scientific definition, (from above ” diminishing marginal returns also implies a technological relationship”); diminishing returns is merely similar to the scientific/mathematical principle of asymptotic behavior. Using a natural analogy is much like using a metaphor in literature. Analogous explanations are used to illustrate the properties of a concept in a situation that may be more familiar to the pupil. “Many economists will say that hydrogen bonds are responding to economic laws — as though the fact that they discovered the pattern means that everything that it describes falls within their field of study.” I’m not sure what economists you talk too. Most I know would shudder at the thought of the quantum description of bonds. Furthermore, to your comment of dimishing returns (b) is not equivilent to a plateau or a leveling-off”. Both the definition and the illustrative example posted on Wikipedia suggest diminishing returns behaves similar to asymptotic behavior. The reversal you mention in the behavior of water density with changes in temperature at 4C is not asymptotic (at least you got that right). With regards to your payphone example… “For example, with respect to a phone, the system must be reasonably free from certain types of glitches at the moment that I insert the coin; e.g., a nearby utility crew might accidentally cut the line or there may be a scheduled outage, and all of this occurs within the framework of a functioning system.” Unfortunately, you still seem to misunderstand causality yourself. If for some reason there is another variable that has greater influence, that prevents something to happen, the causal relationship between placing coins in a payphone and the ability to place a call is not invalidated. In climate, this would be the magnitude of forcings. O’ wise one, please tell me then where the failings in my original example of a causal system exist. That’s really great that you think the Baconian model of science is flawed, which is why we don’t approach science in that manner. Ocassionally, it may give a useful starting point, but in the end you often don’t know any more than when you started. Perhaps you should actually learn how science is done first hand, given your god-like wisdom, I’m sure it would be benificial for us all to learn from you. Your statement “There are several answers to 0/0. The systems I work in generally call it NaN. Again: old news.” is unfortunately false. In standard algebra, there is only one answer to 0/0, the undefined as pointed out. The multiple answers are only paradoxes that arise from tacking different approaches to finding an answer, but not the correct one, much like my powers of zero example. Hence, using logic alone you cannot always reason the correct result. “After they’ve survived enough attempts at being eliminated, the fact that there are an indefinite number of other theories with the same result becomes irrelevant. At that point, the cost involved in ferreting them out becomes prohibitive; entrenchment has real economic value, and a theory in the hand is worth two in the bush.” I would agree that the cost in trying to find another theory among the other possible solutions to a problem when one has a perfectly good working theory is not worthwhile, but upon occasion, these theories crop up as we examine other systems. In that case, one has to make a distinction based on observations or the predictive properties of the respective theories. If this is not possible, then we often invoke Occam’s razor (as mentioned above). “In any case, aside from the fact that your mastery of Goedel’s theorems is less than impressive, this discussion of Goedel’s theorems is pointless. If someone points out an out-and-out contradiction in a mathematical proof, it won’t do to say, “Ah, but you forget about Goedel’s theorems!†Nobody justifies actual contradictions by referring to Goedel’s theorems.” No one has to do so as once an out-an-out contradition occurs, then we all remember that inconsistent systems are complete, and because we pefer self-consistency over completeness, we look for a new set of theorems, one which is self-consistent… Unless you are a mathematician and wish to study complete systems. Your statement about set theory does not invalidate Goedel’s theorems–by chosing a set which cannot contain an infinite number of elements, you have defined a system which is now complete, but not self-consistent. Again I’ll point out that your comparison of climate models with securities markets, which are economic (they involve monetary system don’t they), are similar. There is no current set of provable physical laws in the securities market, which does define the climate system. Although both are chaotic to a degree, predicting security market behaviors in the end is really rolling dice. The climate system on the other hand, can be on average predicted well within the stated accuracy of our climate models for many decades out. Note that predictions of climate models in the 1950′s predicted many of the behaviors we saw in the decades proceeding them. With our improved knowledge of the system today, we have a higher degree of accuracy for future predictions. I’m not saying that every part process within the GCM is modeled correctly, just that we have certainly captured the average nature of the system to a reasonable level of accuracy and precision. Using the argument that we can’t predict the future of the climate system because we can’t check the answer is an empty statement (I define what I mean by this in my first post). I’d actually like to know what knowledge of the climate system and models you have beyond that which I have told you. Especially since you still try and argue philosophically about scientific arguments. Science is based on facts, observations and physical relationships, which you seem willing to accept, but unwilling to use to back up to support your arguments about the climate. The only one that you mention is the inability of the climate models to appropriately model cloud microphysics does not itself invalidate the models. Our uncertainties in cloud physics (which we can bound) is captured in the “conservative” estimates of uncertainty. So if you wish to continue arguing stick to scientific facts and arguments. |
Clark, you should read Lauden on the topic. dhasterok: You really are the pompous jack@$$ If this is news to you, then you need to get out more. Even so, it strikes me as curious that you find me to be “hopelessly uninformed,” yet you’re upset that I claim to be smarter than you. dhasterok: You state “Diminishing returns is a mathematical pattern that (a) occurs in nature.” Please provide me a reference to this. First of all, this question illustrates of one of the problems of this discussion; viz., you respond to arguments that you don’t bother to read. As I already stated: The Wikipedia article itself uses an example from nature. Specifically, it’s describing the ratio of sewn-seeds to resulting plant-product. You measure the seed and you plant it. You harvest the plant and you measure the harvest. Neither of these is an economic process. The question of the economic value of the seeds or the harvest on the open market is altogether logically independent of this. Furthermore, I provided the example relating to water density. Where there are ready examples that we both agree on, there’s no point in making appeals to authority. The Wikipedia definition is very obviously incorrect. Diminishing Returns eventually leads to diminishing overall returns — not merely a diminution of additional returns, and this diminishing overall return entails a falling off from a peek. Thus, when you dump too much seed on a field, you don’t simply get fewer plants for each additional seed. At some point, you actually get fewer total plants. This is so obvious that it hardly requires a citation. However, I’m nothing if not accommodating (I’m still responding, aren’t I?). A quick google turns up “The Columbia Encyclopedia (“diminishing returns, law of.” The Columbia Encyclopedia, 6th ed. New York: Columbia University Press, 2001–04. http://www.bartleby.com/65/), a real encyclopedia:
What is actually identified as “the point of diminishing returns,” (or the point at which the diminishing return trend begins) is the first threshold that I identify (where each additional element contributes less to the overall result than the previous element) and not to the second threshold (where each additional element begins to detract larger and larger amounts from the overall result). This may lead to some confusion concerning the nature of diminishing returns itself. Nevertheless, it is a dual threshold pattern. For example, check out the article on diminishing returns at Chris Rodda’s Economics for International Students site. It actually graphs a diminishing returns function, and (as you will see) it does not resemble asymptotic functions, because it retreats from its peek (as is shown be the fall of the line measuring TPP in the first graph on that page). The fact that this occurs in nature is proof that it is not limited to the realm of economics. As I’ve mentioned repeatedly, it is a pattern that can even be shown to exist in water, which is not governed by any principle of production at all. When you think about it, it’s rather strange that economists seem to think they have a monopoly on this pattern. A key problem here, though, is that you don’t tend to think about things. Given how little I know about economics, it strikes me as self-defeating that you’ve set yourself up to be on the losing side of an argument with me about economics, and that you continue to pursue it when it has nothing to do with the other issues at hand. Nevertheless, I have an inkling that, in spite of all this, you’ll continue to attempt to salvage your position. dhasterok: If for some reason there is another variable that has greater influence, that prevents something to happen, the causal relationship between placing coins in a payphone and the ability to place a call is not invalidated. This is completely beside the point, because I’m not claiming that the cause is “invalidated.” (I don’t even know what that would mean.) I’ll say it again, in hopes that this time you’ll read it: There must be some baseline set of conditions in place in order for a factor to function as a cause. The gun won’t fire unless its loaded. The (corded) phone won’t give you a dial tone unless its plugged in. Pavlov’s famous dog won’t salivate if you ring the bell in a vacuum. Causal relationships are defined in terms of these types of baselines (whether implicitly or explicitly), and there’s no sense in which the cause is “invalidated” when the set of baseline conditions fails to occur. Again, you’re just grasping at straws regarding causation. Moreover, you fail to address my point about the system or framework determining the possible causes of an event. dhasterok: Your statement “There are several answers to 0/0. The systems I work in generally call it NaN. Again: old news.” is unfortunately false. In standard algebra, there is only one answer to 0/0, the undefined as pointed out. The multiple answers are only paradoxes that arise from tacking different approaches to finding an answer, but not the correct one, much like my powers of zero example. Hence, using logic alone you cannot always reason the correct result. I fail to see how pointing out that there is another answer to 0/0 besides NaN contradicts my point that there are multiple ways to solve 0/0. The multiple answers are not paradoxes, because they exist within mutually exclusive formal systems. As you pointed out, systems (scientific or otherwise) simplify, and not all simplifications are suitable for all types of problems. Hence the need for different approaches which will inevitably yield different results. The numbers in the systems I use are defined by international standards; viz., the cluster of standards surrounding IEEE 754. By these standards, 0/0 = NaN. These standards were not created because of paradoxes; they were created because standard algebra is inadequate for the task. It’s quite obvious that you haven’t the foggiest idea what you’re talking about here with regard to mathematical systems, or even formal systems in general. dhasterok: No one has to do so as once an out-an-out contradition occurs, then we all remember that inconsistent systems are complete, and because we pefer self-consistency over completeness, we look for a new set of theorems, one which is self-consistent This makes no sense at all. Because Geodel’s theorems do not say that a system cannot be both incomplete and inconsistent at the same time, the existence of a contradiction within a system doesn’t imply anything substantial regarding the system’s completeness. Besides, you’re missing the point. Science is not a formal system. Geodel’s theorem has nothing directly to do with it. dhasterok: There is no current set of provable physical laws in the securities market. Listening to you, one might think that investing was equivalent to playing the Lottery. But there’s a reason why insider trading and price fixing are illegal — they work. I’m glad that you’ve decided to stop disparaging my possible avenues of intellectual interest, but your still fluttering from point to point trying to find areas where you can show that I’m wrong, and you come up dry every time. At this point, we’re not even talking about science anymore, were just trudging through the remaining topics where you think there’s some hope you might appear to be correct. It’s a bit embarrassing to read the mess that you make of such areas as Geodel’s theorem, securities markets, and simple mathematical theory (just to name a few). As ignorant and unschooled as I am, it’s astonishing that you’ve yet to find an argumentative point on which you actually know more than me. You continue to (a) grasp helplessly at principles that you do understand but which are utterly irrelevant, or (b) try to put forth new ideas based on what you read in Wikipedia. I don’t understand why you would think that this is a constructive approach to arguing. |
DKL, interestingly I had just read Lauden on the topic. |
To add, some of Laudan’s reformulations of the D-Q thesis are interesting. I just realized you wrote Lauden and not Laudan (as did I initially). Are we speaking of the same guy? Larry Laudan has a fairly well respected paper, “Demystifying Underdetermination,” which is about the D-Q thesis. He also deals with Gillies’ attempt to reformulate it. Laudan notes, which I think is correct, that the D-Q thesis as used is often problematic because it is so equivocal. Folks use it in a vague and often inconsistent fashion. (Kind of like paradigms by Kuhn and people referring to Kuhn – something Kuhn himself noted in his later works) I should add that Laudan deals well with Kuhn’s use of the underdetermination thesis as well. |
This is my first, and probably last, post to the forums, as I generally have too much to do, and too little time to do it. :) Also, in case someone finds First, some notes in response to DKL, so we can usefully discuss what I really want to talk about later: “Diminishing returns is a mathematical pattern that (a) occurs in nature, The term “diminishing returns” is defined in general usage and all the Reversing patterns are not necessarily “diminishing returns” – the definition “For example, you do not understand how baseline conditions No, there isn’t, by the definition of a system.

“Economic models (including the currency exchange models brought up by DKL) ARE I don’t want to derail this into a discussion of philosophy of science. I recognize that’s rather irrelevant to whether global warming can be verified scientifically. (I think it has, at this stage, been overwhelmingly verified) However I’d just note that a scientific model need not entail an universal physical law. Indeed typically they don’t. Further one could point to thermodynamics and say nearly everything you said about economics. For instance is the ideal gas law anything other than a made up realm? Nothing actually behaves that way. Why is it bad in economics but good in physics? There’s definitely a double standard at work. Now I think there are some great places to criticize the social sciences if one is going to narrow the nature of science down. (As physicists are sometimes want to do) However I think that gets at more the ontology of the ultimate substances – i.e. what is a mathematical artifact versus what is real. Of course that sort of critique presumes one verges towards scientific realism rather than empiricsm or instrumentalism. |
Clark, Lauden or Laudan, you know me. If it’s not in the spell-check dictionary, then I can’t spell it. I’ll just call him Larry. In any case, the way that I’ve used QD here (to show why after-the-fact explanations do not count as evidence of predictive validity) is entirely consistent with an appropriate usage. PGGettings: The term “diminishing returns” is defined in general usage and all the technical work I’ve ever seen or heard of as a “leveling-off”… What the system does afterwards is irrelevant as the definition doesn’t say anything about behavior after the “inflection” point… it may become negative, but IT NEED NOT. Wrong, PG. Now that I’m no longer at work, I’ve access to my books at home. Here’s the definition provided by Thomas Sowell, a prominent academic economist (and a well-known political writer), in his book Knowledge and Decisions:
This should come as no surprise to you, since it is in line with the examples used in every source sited in this thread. Moreover, it is consistent with solid interpretations of the definitions provided in each example except the Wikipedia article. In any case, this is not a “leveling off.” So give up on the diminishing returns thing already. Seriously, how many times do I have to demonstrate that you’re wrong before you’ll give up? PGGettings: No, there isn’t [anything besides a system in a baseline causal condition], by the definition of a system. All the interactions and actors are contained within the system. Irrelevant. I’m not positing anything outside the system. My discussion in comment #216 states, “a nearby utility crew might accidentally cut the line or there may be a scheduled outage, and all of this occurs within the framework of a functioning system.” (italics added) I am describing a condition within a system that blocks causation. At this point, I’m going to guess that you’re one of dhasterok’s teachers, because he seems to share your unwillingness to actually read something before arguing with it. Let me explain to you how causes work (and please, let’s skip the argumentative phase where you complain that I’m not using the latest, de rigueur terminology — you should be able to get the idea clearly enough, or at least ask if you don’t): Start with the salient factors that contribute to some repeatable pattern. If you change any one of these factors while all the other salient factors are held constant, the change in that factor is identified as the cause of any change in the pattern. And any of the other factors can be treated as causes of the same (or similar) changes in the pattern, provided that their manipulation results in the same (or similar) changes. The factors that are held constant constitute this baseline condition that I’ve described. The system defines or stipulates the ontology of salient factors as well as the predicates that constitute the legal scope of their possible manipulation. Thus, different systems give rise to different causal analyses. Aristotle notwithstanding, nothing is a cause in-and-of-itself. In the pay-phone example, the other factors that constitute the baseline condition for a quarter causing a dial tone will typically include things like the network, its condition, and the pay phone not being full — all things that are tracked within the system. Honestly, PG, this stuff isn’t that advanced. You should have gone over analogous concepts in test-tubes 101. PGGettings: Please explain why a multiplicity of causes is relevant to this thread? I’m not sure why you’re asking this, but (as I said) I’m nothing if not accomodating. As I explained in the comment you site: dhasterok gives the impression that he belivees causal relationships to have some metaphysical import — like there is a single, real cause to be identified, just like he mistakenly thinks that there is a single, real answer to 0/0. As an aside, the statement about a multiplicity of causes builds on something I’d said in a preceding comment, and (since it is a key argument against modal realism) it emphasizes that such metaphysical import is not a given, and there is generally not a single, real cause. PGGettings: Science need not explain why the world works the way it does, so long as it can accurately, comprehensively, and understandably predict the way the world will act. That’s like a politician saying “The working man deserves a fair shake.” It’s the kind of thing that everyone can agree to, provided you don’t ask what anything means. Since all the key disputes hinge on what constitutes accuracy, comprehensiveness, and understandable-ness, this statement is pretty meaningless stuff. PGGettings: There appears to be a general misunderstanding in much of the public… about the process and limitations of scientific modelling… It’s too bad that with the limited time at your disposal, you’ve gone to so much trouble to describe exactly what models are and how they are useful. There’s no misunderstanding there on my part at all. As I’ve stated repeatedly: My dispute concerns what kind of evidence actually tests the predictive validity of a model, and what kind does not. I have no beef at all with the effectiveness of scientific models per se. PGGettings: Economic models (including the currency exchange models brought up by DKL) ARE
NOT SCIENTIFIC MODELS. Again, It’s too bad that with the limited time at your disposal, you’ve gone to so much trouble argue about economic modeling. As I’ve stated repeatedly. Securities market models are not economic models. Many (if not most) of the people who design them and use them are not economists and have no economics training at all. Furthermore, cheers to Clark for showing exactly how your proposed differentiation between “hard” physics and other rational endeavors is hogwash. He was, I believe, more succinct than I might have been. The fact that you still cling to that prejudice which takes “physical laws” to be somehow (almost magically) different from any other sort of observed regularity demonstrates something important: like dhasterok, you’re doing little more than passing on what you’ve been taught, and you’ve given very little thought to whether it makes any sense at all. This is likely what gives rise to your propensity to make bold, yet egregiously incorrect statements. Since you don’t seem prepared to begin thinking about things, all I can do is bemoan the fact that you didn’t have better teachers. PGGettings: …modern climate models are trained on the period up to ~1750 And my comment #113 shows exactly why such known data sets are not good judges of the predictive validity of a system. You haven’t laid a finger on that. All you’ve done is go on about economic models. PGGettings: By combining the results of a great many runs with different models, different starting parameters, and different forcings, we (as a civilization) can get a good sense of what the Earth’s climate is likely to do over the next few centuries. So once the model is created, what counts as evidence that the model is flawed? Nothing. Yet another reason why it’s a bad model. PGGettings: Models are useful, tricky, and the basis for everything we know and love. I know. I constructed a model of my very own at the outset of my involvement with this thread. To describe it informally, the import of it is this: It stipulates that the degree to which one uses this thread to describe how she believes that long-term climate models have predictive validity (based on their performance against canned data sets) is the degree to which she can easily be shown to misunderstand how science works. So far, it’s survived two attempts to falsify it. That means it’s doing a heck of a lot better than your climate stuff. Look, from what dhastorek has implied, you’re some kind of a professional scientist or something. The most prominent features of your writing are the lack of understanding that you (a) assume in others, and (b) display in your own writings. Sadly, your comment is, on the whole, more given over to irrelevant ramblings, straw men, and glaring errors than those of your predecessor, dhastorek. |
DKL: Generalizations that can be refuted by critical examination are scientific generalizations, but they needn’t be based on observing past behavior and they needn’t be liable to predictive validity. Um, I’d just like to point out that scientific theories are based on observations that really do kinda qualify as “past behavior.” If a model isn’t predictive it tends to be thrown out in favor of better descriptions of the system. You ask a fair question when you ask if climate models from a decade or so ago accurately predicted the warming we’ve seen. The answer to that is, yes. The warming we see today is well within the envelope of warming predicted in the late 80′s and early 90′s. In fact, it’s reasonably in line with the first climate model that Arrhenius produced more than a century ago. The signal at this point is very small (less than a degree C), but it is more than likely over the next decade or so we will see much more of a signal from anthropogenic greenhouse gases. Clark, I appreciate you agreeing that global warming is a given. I’m going to quibble with you about the comparison between thermodynamics and economics. Thermo is an approximation (thus the ideal gas law) and it works over appropriate scales. In fact, the ideal gas law works really well for ideal gases, like helium and the other noble gases that don’t interact with each other. It’s even a reasonable approximation for molecules like water and CO2, that do interact with each other in the gas phase. There is a physical reality behind the ideal gas law (determined by the kinetic energy of particles in the gas phase and their interaction with each other) and that reality would be the same if we were on Jupiter, Alpha Centauri, or anyplace in this universe. I doubt you could truly say the same thing about economics. In fact, I certainly hope you can’t! I would hate to think that the economy of heaven will be the same one that rules our fallen world here. |
Kristine N: Generalizations that can be refuted by critical examination are scientific generalizations, but they needn’t be based on observing past behavior and they needn’t be liable to predictive validity. You’ll have to excuse me for finding it bizarre that you’re offering this up at this point in the thread as some kind of counter-argument to me, since this is exactly the point I was arguing against Devyn’s assertion, “we can look at past behavior of the earth and make somewhat reasonable predictions about the future. This is the entire basis of science” in my comment #127. Kristine N: The warming we see today is well within the envelope of warming predicted in the late 80’s and early 90’s. Fair enough. My questions were, of course, quite a bit more specific than this. |
Dear sirs, In regards to the definition of diminishing returns, please decide which definition you would like to use. All three you have brought up so far include the asymptotic behavior, but only yours and Sowell’s requires the overall reduction of production. The other two you cited do not, although their examples show overall reduction for illustration of a possibility. I personally prefer definitions which ignore the behavior after the “inflection” point, as it makes the concept more general. I assume you prefer yours for your own reasons. In regards to the definition of causes: I see we (DKL and I) agree, but I am interested to know why DKL uses the terminology “baseline conditions”; in the scientific world I come from, these have a very different meaning of the initial state of a system, which is not at all related to causality. Is this definition from philosophy? In regards to Clark’s comments on models: I am curious to hear which scientific models do not entail physical laws? All those I can think of, or have dealth with, are based on computing the evolution of a system due to the laws of physics. Arguably, automata-based systems do not “follow” the laws of physics, but that is a difference of algorithm not intent. There is not a double standard; if we can derive/define a universal, invariant law of economics that is correct everwhere for all times, then an economic model would be just as good as a scientific one. The problem is not the models, or the math used to build the models, but the underlying systems that the models are attempting to capture. I pointed out the difference between economic models (which are attempting to capture a system without fixed rules) and scientific models (which are attempting to capture a system with fixed rules), because they illustrate the two end members of modeled phenomena. The contrast between the underlying rules of the systems is the important fact here, and I spent time on them in my first post to try to illuminate the differences. Note that economic models, including securities exchanges, model markets of any type, regardless of who builds or runs the model, and that these markets do not behave according to any known fixed rules. By the same idea, the vast majority of scientific models are built by average people to handle daily life, even though they are not officially called scientists, and they are successful because the physical world does have fixed rules. Note that there still appears to be a misunderstanding of the need to train models. Part of this could be from terminology: scientific models are not “trained”. They are run forward from an initial state (baseline conditions), evolving according to the specified physics. When we speak of climate model training, what we are actually talking about is the use of a known instrumental record to check the simulation state over time. If the simulation doesn’t match the instrumental record, we change the baseline conditions or the sensitivity of a feedback, not the physics. Proxy, economic, and other transfer-function based models change the rules (physics) of the model to match the training data, as we do not have a set of invariant rules to follow. There are models in science that follow this pattern, and they are used for interpolation only due to the danger of extrapolation; anyone who does curve fitting without an a priori knowledge of the curve form should never extrapolate based on that fit! Since climate and other complex systems are non-linear and demonstrate emergent behavior, we cannot predict the exact future state of the system with perfect accuracy (see previous post for why). But, we can predict the range of possible states, and their probabilities by combining a large number of simulations to map the possible phase space of the future state of the system. This is exactly equivalent to the inability to express the exact position of an electron, but the ability to state the probabilty density function of the electron’s position with great accuracy; proof of our ability to use statistics to handle this complexity is that we are using computers to chat about this. So, if one chooses to disregard the difference between systems without time-varying rules (i.e. physics) and those with (i.e. economics), then there is no difference between a climate simulation and a securities model, and their results are of equally tiny value (models which cannot be used for extrapolation are nearly worthless). However, the history of technology shows that there is a difference, and that difference can be exploited to produce models which can predict, with arbitrary precision (given sufficient computing resources and measurements of the baseline conditions) the future evolution of a deterministic system. Since climate (not weather) can be made a deterministic system, we win. Off to my real job…. |
I am curious to hear which scientific models do not entail physical laws? I thought I gave one: the ideal gas law. But arguably Newton’s Laws aren’t really laws but clearly they are useful scientific models. |
“In any case, the way that I’ve used QD here (to show why after-the-fact explanations do not count as evidence of predictive validity) is entirely consistent with an appropriate usage.” Certainly Laudan would agree with you. I’m not sure I buy his Popperian approach though. But clearly Quine’s assertion that empirical adequacy entails equal support is incorrect, if only because we consider predictive validity more valuable – and thus a second theory that explains the same evidence oddly has less support. I say oddly because there seems to me to be something wrong about reasoning in that fashion – one reason I’m a bit distrustful of Bayesian methods in epistemology. As I said though, I don’t want to derail the discussion. Kristine: I’m going to quibble with you about the comparison between thermodynamics and economics. Thermo is an approximation But the selfish actor within economics isn’t an approximation? The problem with what you say is that these things are developed different from what you assume. Further the whole point of any approximation is that it is now dealing with an imaginary realm. This was one of the points Durhem made about Newton’s claim to have developed his models from Kepler’s. The problem is that if Newton’s laws are true then the solar system is a multibodied problem and Kepler’s laws are wrong. We can say they are an approximation but then they are in some ideal land and not reality. The double standard is that some scientists allow “fictional realms” in their own discipline and call it “approximations” but when scientists in other fields do exactly the same thing it is something else: usually described disparagingly. Now it can’t simply be that say physicists have the right models and thus we know these others are approximations to the right answers. Since typically the “approximations” come first and are treated as scientifically valid and only later, as a better description comes, are they then relegated to “approximate” status. So why is the economic view with some assumptions about actors wrong? There really does appear to be a double standard. |
this is reminding me of the line: ” I lost interest at about post #68, wherein Dan posted the Internet.” I like you, Dan, but that was really funny. I think of it everytime I read a long post. |
PGGettings: In regards to the definition of diminishing returns, please decide which definition you would like to use. Don’t pretend that I’m all over the map here. I’ve stuck to one definition, and one interpretation of the verbiage used by others. Sowell is simply more direct than they are. Besides, my only point was that the curve that I describe in my definition is not asymptotic. I brought this up merely to respond to one of dhasterok’s ignorant “In science, it’s called a…” assertions. I’ve stated over and over again that it just doesn’t have any relevance to the argument. PGGettings: In regards to the definition of causes: I see we (DKL and I) agree, but I am interested to know why DKL uses the terminology “baseline conditions”; in the scientific world I come from, these have a very different meaning of the initial state of a system, which is not at all related to causality. I’m not sure in what sense we agree. I use the term “baseline conditions” because it’s descriptive, and because it is not necessarily the initial state of the system, and therefore not identical with the term “initial state.” PGGettings: Is this definition [of a cause] from philosophy? It’s from my head. I just made it up as I typed it. It reflects my understanding of how causes work, and it ranks among those very elementary pieces of information that I’ve known long enough that I’ve forgotten exactly where I learned it or even if I learned it all in one place. I should inform you that I write pretty much all of my comments on blogs this way — from the top of my head, though I often have a vague recollection of sources (as I demonstrated by locating the Sowell definition of diminishing returns) and I very occasionally will remember exactly where something comes from. I make no pretense at all to performing research before I comment — in fact, I generally disavow it, because I want the exchange to be as conversation-like as possible. PGGettings: Proxy, economic, and other transfer-function based models change the rules (physics) of the model to match the training data, as we do not have a set of invariant rules to follow. I’m done arguing with you over whether market models are models from economics. If you want to get your stock purchasing advice from an economist, feel free. At any rate, you still don’t understand how securities market models work. I can best illustrate this by constructing a simple securities market model for you illumination (again, off the top of my head — honest, you can’t google this crap). For securities markets governing immediate purchases, you want to buy when the market goes up, and sell when it goes down. This is true simply by virtue of how the market is set up. There are guaranteed ways to anticipate gains and losses in security markets, and these are made illegal by copious laws and regulations. On to the model: Say we call the price of a security that we wish to buy x. We can say that when x reaches x + y, we buy. Once we own it, we sell it when it declines by z, regardless of the amount of time that has passed. This is simple enough that you can program it into a spreadsheet. If you get the high/low/close data for one year of a given securities item (be it a stock or a foreign currency or a commodity future), you can see how well you will have done. x will be the originating price of the security. You train it to figure out a roughly optimal point for y and z (generally, they’ll be equal), because you’ll want to optimize the profitability per trade in order to offset the cost of trading (which can, of course, be represented within the model; I’ve left it out here for simplicity). If you figure out the reasonable number of price units that y and z should represent, and you implement this model across enough securities (e.g., at least 12 or 15), then approximately 60% of your trades will be profitable over a large enough set of trades. Go ahead and try it for yourself. As I’ve asserted repeatedly — this has nothing to do with free agency or human choice. Plus, there is no time variance here at all. In any case, as I’ve stated repeatedly, this is all beside the point. If the physics models worked as you described with regard to climates, then we’d only ever need one climate model, and then the question would be settled. The truth is, we don’t know which physics rules have which impact on the problem, and we’re throwing together rules and adjusting how they interact in the exact fashion that you accuse economic models of doing. In other words, the question needn’t be the underlying physics, but the relative significance of each physical rule being accounted for. I still think that you’ve failed to demonstrate an adequate grasp on the issues at hand. |
Clark–the thing is, approximating all people as selfish actors is a bad approximation. Even if you assume people are all selfish, how are they selfish? there are very different ways of being selfish, all of which lead to distinct behavioral patterns. Atoms and molecules (to use the ideal gas law again) just aren’t that complicated. Yeah, the approximations are “imaginary” in some sense, but they work, they have predictive power, and we’re pretty sure you can, in fact, say something about the behavior of an individual molecule based on the model. I’m sure you’re going to tell me you can do the same thing with economic models. Fine. I’ll agree that in a general sense you can say something about individual behavior based on economic models (like, people will buy less if things cost more), and you can, again, in a general sense, predict an expected behavior or evolution for an economic system, particularly in response to a given forcing. But you can’t get very specific with an economic model because human behavior can’t be quantified and generalized to the degree that would be necessary–it’s too chaotic. The point of the argument that DKL et. al have been forwarding is that because economic models can’t predict the behavior of the stock market, all modeling must be worthless for prediction. I wholeheartedly disagree with this sentiment. Climate is far less complicated than economics, far less complicated than the stock market, and we can generalize the behavior of the (much smaller number of) subcomponents to produce a reasonably predictive model. I’d also like to point out that the “predictive models” DKL is talking about are probably most analagous to weather models. People who are interested in the kinds of models DKL was talking about are probably making their money on relatively minute fluctuations in the prices of money that should be within noise. DKL–I was quoting you, which you might have figured out if you’d bothered to read the second statement well enough to realize it’s a refutation of the previous statement. |
“the thing is, approximating all people as selfish actors is a bad approximation” I disagree. Indeed what is so amazing about economics is despite what I take to be some highly questionable assumptions they actually have a lot of predictive power. Further I don’t think they are much worse than many predictions in physics over the centuries. The fact you can’t get too specific about the predictions of economics isn’t a bug, it’s a feature. Complaining about that is akin to complaining that Newton’s laws don’t work for subatomic particles or that simplified fluid dynamics can’t explain turbulence. Lots of physical “laws” in physics only work for simple non-chaotic systems. Heaven knows I’ve done enough fluid dynamics and plasma dynamics to see where that’s true. The trick is simply to know (and test) the bounds of your model. Note that I do agree with you vis a vis DKL and the predictive power of models. The fact neither economic nor climate models can predict everything says little about what they can predict. Ditto, again, for my fluid dynamic and plasma models. This is a common objection, but a flawed one. Although I do tend to think it was much truer of many climate models back in the 90′s when I was still a global warming doubter. However I think the science progressed to the point where most of my objections were answered. |
Clark, I think that you miss the point of my argument if you think that I’m questioning whether the models can predict everything. I’m making a much stronger assertion: specifically, that there’s very little basis for saying that they can predict anything at all. kristine N: DKL–I was quoting you, which you might have figured out if you’d bothered to read the second statement well enough to realize it’s a refutation of the previous statement. The problem isn’t that I didn’t read your second paragraph. The problem is that I don’t see how the second paragraph contradicts or disagrees with the first paragraph. Perhaps you can be clearer on exactly why you take my agreement with the first paragraph to entail disagreement with your attempted response. I think it’s a little strange that you actually think that you or dhasterok or PGGettings have a basis or a footing to continue arguing here. Whether it’s been causation, Goedel’s theorem, or division by zero (PGGettings now agrees with me about causation, but she proved unable to actually formulate an intelligible definition of causation and did little more than propagate common misunderstandings until he read my definition), you’ve proven repeatedly unable to demonstrate an effective grasp on the issue. I’m the only one here who’s been able to demonstrate that he’s read non-google’able sources on diminishing returns. For all your talk presuming to explain how “economics models” worked, I’m the only one participating who can formulate and has actually formulated a securities model to show how they really work. I challenge you to identify a single instance where we’ve disagreed where you’ve decisively demonstrated a superior level of knowledge. And after all this, you come back to argue with me as though none of this has happened — as though you’re still on equal footing here. And your response is to bicker with me because you can’t understand an assertion I made about Anaxemander in an earlier argument in this thread. What makes you think that this discussion will be any less abortive for you than the previous ones? Are you really that desperate to score a point that you’re blind to this pattern? |
Yes, but I think that empirically incorrect. That is one can simply look to the predictions and, in terms of particular claims, see how close the predictions match. Now it’s a tad more complex than that since typically you run the models many (often millions) of times and get patterns. The issue of empirically verifying such distributions is a complex one. My sense is that is what you object to (although I may be wrong). However my personal feeling is that there are patterns within the models that given empirical verification. Much like while models are pretty lousy for predicting local weather a week away, they are pretty good for predicting weather up to three days and so-so for five day forecasts. |
Clark, I think that you’re still arguing beside the point. I’m not arguing that the models can’t be tested (though that’s also a potential problem), I’m arguing that they haven’t been. My point is this: I’m stating that running the models against known data sets says nothing about their predictive ability against unknown data sets (e.g., future climate data). You’re saying that we can see how well they work in the future, and gauge their predictive validity that way — and I certainly agree with this, to the extant that it’s possible. But until that occurs, there’s no basis for saying that they have predictive validity. Thus: The scientists here keep claiming that the models have predictive validity due to their performance against the known data sets that they were designed to explain. And they’re wrong. PGGettings seems to think that because the physical laws underlying the models are correct, that the models are correct. This is (yet another) example of the fallacy of composition. One can create obviously mistaken models that utilize Newton’s gravitational equation all the live-long day. |
But DKL, on what basis do you say this hasn’t occurred. All the evidence I’ve seen says it is. One makes predictions from the models and sees how that pans out over a year or two or from datasets that weren’t included in the original model. It seems to me that you are asserting this isn’t done whereas most of what I’ve read suggests it is done. |
Clark–Okay, I went back and re-read your arguments trying to figure out how we got to this point in the discussion. I see I have done nothing but prove your point that scientists quibble with the models other scientists (especially social scientists) use. You got me–I’m saying that other people’s models aren’t as good as mine. I’d like to point out this is a feature of scientists in general–everyone believes their model is better than everyone else’s, that the assumptions they make are somehow more correct than the dumb ones other people make. You’re pointing at this phenomenon and saying physicists make unwarranted, disparaging comments about the social sciences. Yes, they do, but they also do the same thing to the chemists and geologists and especially the other physicists in the room. Honestly, as annoying as it is, this behavior is what makes science better. Getting back to what makes a model good or not, I think we should find some point of agreement. I think we can agree first of all, that models are simply mathematical descriptions of a system. Some of these mathematical descriptions are empirical (often simple regression where change in x produces offset in y, related by some slope, m, and some offset, b). Other models are based on physics, meaning, they are outgrowths of some other behavior that can be mathematically modeled. Thermo, for example, is an outgrowth of the quantum mechanical behavior of atoms. Even though the math was originally derived from observations, you get the same math out of quantum. The math is always an approximation somewhere, but there is always a physical reality to the model, whether it is an empirical or a derived model. If this were not the case, the model would be useless. There is a physical reality to atoms in the gas phase bouncing off one another like billiard balls and against the sides of whatever vessel is holding them, creating pressure. The physical reality of these interactions is what underlies the ideal gas law and is why the math works. Likewise, with your economics model there is a physical reality to describing all people as selfish actors within an economy. People are, on average, selfish, and on average will make the selfish decision, which is why economics models have the explanatory power they do. the point PG is making above (and I agree with) is that there are hard and fast laws–behaviors that atoms have no choice in obeying–underlying the ideal gas law. Atoms have to act the way they do because there are physical laws governing their behavior. This is not true of individuals in an economic model. Yes, people do tend to act a certain way, but there is no law saying they have to act that way. The system is, in some sense, arbitrary because we individuals have a choice in the way we behave. That’s not to say the models aren’t useful (because the are) but the system is unconstrained in a way a physics model isn’t. DKL–you claimed models aren’t based on past behavior of a system, which is false and I said that. |
I’ve been absent for a few days and it seems that quite a bit has happened. DKL, I see you passed up an opportunity to argue about the real science of climate change. Is that because you don’t actually understand the science that goes into the models? You still hold this belief that they can’t be right because you don’t want them to be? That’s the same type of logic that makes people say “Scientists just believe in global warming because they have an agenda.” I’m actually curious what agenda people think the bulk of scientists have. I’m surprised to see that after the numerous websites that you have now read about diminishing returns you still fail to acknowledge that it is an economic construct. Regardless of whether it peaks and falls off or does not behaves asymptotically is beside the point (it does seem that there are a number of descriptions which describe both processes). However, every definition explains that it is an “ECONOMIC” law. Or apparently you have missed this. It is a definition within the construct of economics. There are other terms that describe the behavior of similar systems within engineering, science and math. SOCIAL SCIENCE vs. SCIENCE … or … PEOPLE vs. PARTICLES DKL, you are still not seeing the difference between a science (esp. physical ones) and a social science (economics, psychology etc.). Let me give you an example of the difference. Scientific principles are deterministic whereas social science principles need not be. Deterministic systems work in this way. If I were to run an experiment, I would get the same outcome every time. If the outcome is different every time, then the system is not deterministic. Now I’ll get to probabilities shortly since that can fuzzy the boundary between a deterministic and non-deterministic result. Lets take an electron for example. If I send a moving electron through a set of charged plates one negative and one positive, then the electron will always curve towards the positive plate. In fact, it will curve towards the positive plate at a rate proportional to the voltage across the plates. It doesn’t matter how many times I run this experiment I will get precisely the same result. And I can take the electron and strip it off a hydrogen atom to run the experiment or one off of a uranium atom and run the experiment. I still get the same result. I could run the experiment next week, next month, next year or 10 billion years from now. I could try the experiment in Chicago, Timbuktu, or in the Andromeda galaxy. I will Ok, now how about the converse in a social science. Since we’ve been basically talking about economics the entire time, I’ll give you an economic one. Lets say I play basketball every afternoon with three of my closest buddies. After each game, we are all ready for a drink of something cold. My friend Charlie always grabs a Coke and always has. Anne grabs a Mountain Dew some days, a Fresca others and on the days when he just feels like it, he picks up a grape soda. Heidi is really healthy and skips the soda all together and drinks water instead. Lets just say that there is no telling what I will chose and it really just depends on the day. If the machine doesn’t have what any one of us want on a given day then we skip the machine and head to the local market instead. So if you manage the soda machine and stock it once a week, how do you decide what to stock in order to maximize profits? I’m not sure I really know the answer to this one. Ok, lets say that if you watch us for a significantly long period of time you now have a probabilistic distribution for the sodas we drink. Then making the money is easy as pie and it should be easy to choose how much of each soda to stock, perhaps even when. In cases like this the system (i.e. the four of us and the soda machine) is probabilistic and can act very similar to a physical system. And this is when economics works. When you can develop a model that represents the probabilistic behavior of a market, you can make money. Ah, but then here is the kicker… Suppose our tastes change; suppose they won’t be the same in five years. So now you have to change your model and it may be a fundamentally different behavior. The people within the system have changed their tastes. This happens all the time and is why a company that works well one year may tank the next. It may depend a great deal upon the market (the people whom you are selling the product), where it is located, the demographics etc. This is again Now one argument you would use in response to these examples is obvious. You will say that science can certainly be probabilistic in the case of quantum mechanics or even chaotic in the case of turbulence. And I will say that’s true, but you are missing a few important points about deterministic behavior. First, when particles behave according to a probabilistic behavior, it is always the same probability for a given set of conditions. This isn’t true of economics in the slightest. Because human behavior can change the models may have some short term validity, but rarely a long term predictability. If I measure the location of an electron in a hydrogen atom, I will always get the same probability of location for every hydrogen for all time that has the same amount of energy. This isn’t true of people. For chaotic systems, like turbulence, the behavior is still deterministic. We may not be able to model any one particular particle within a chaotic system, but we can–often–on average predict the behavior of the system as a whole. Hence, from chaos arises order. We can especially predict overall distributions of quantities that are conserved such as mass-energy and momentum. If I had taken any water molecule out of a turbulent stream and replaced it with another water particle in the same position it would have moved in exactly the same way as the original. Social sciences work within a mathematical construct to characterize human behavior. Which cannot be done either completely or even on average for very long term. The latter often requiring that the equations themselves be fundamentally changed. The sciences use mathematics to describe the deterministic behavior of a system, which will always behave in the same manner given the same set of conditions. MODEL TESTING In a couple of earlier posts, I explain how modeling works with regards to the climate system. I’ve shown how we validate our ensemble of models and assess their potential as predictive models. And you still say that you are not satisfied. I’m not really sure how we can satisfy you then. It seems to go a long way to satisfying the bulk of the scientific community. Saying that the climate models cannot predict the future because they can’t be proven correct or incorrect doesn’t mean they don’t give a reliable estimate. This is an empty statement. See my first post which contains my definition of an empty statement. If we can predict what we do see based on the physics we have included, then maybe we can predict the future to the same level of accuracy. I’m not saying we capture every process that occurs within the climate system or can predict every last storm, but on a global average we’re pretty good and we’ve been pretty good since the 90′s. In fact we’ve gotten better and we are constantly improving them all the time. It seems to me that DKL just holds preconceived notions that he is unwilling to let go. There are a number of people that don’t believe that the world is warming. There are also a number of people that don’t believe that we landed on the Moon or that the world is round. There are even people that don’t believe we are genetically related to chimpanzees. All of these doubters believe some set of preconceived notions on how the world MUST work and are unwilling to change their opinions when they can verifiably be proven wrong with scientific observations and arguments. Being a skeptic is fine–in fact it helps make a good scientist–but being skeptical against all evidence is just plain closed-minded. A CHALLENGE FOR DKL DKL please–please, give me something which you believe is a scientific reason why we shouldn’t trust our climate models. I’ll take a silence or philosophical ramblings as a confirmation that you can’t since you have shied away at every opportunity that I previously invited you to debate the science previously. |
Kristine N you claimed models aren’t based on past behavior of a system, which is false and I said that. Well, it’s not false. Generalizations needn’t be based on past observations. This is simply a truism. I can make any number of generalizations up that have no relationship to past observations: Here’s one off the top of my head: “Bricks wrapped in animal fur have greater tensile strength than bricks wrapped in canvas.” Granted’ that’s a pretty useless generalization, but it’s not designed to be. Whether this is true is an empirical question, and thus is empirically falsifiable. It is therefore scientific in a sense that you and I can both agree on. And it’s not based on past observation. (Even if semantic components can be shown to originate in previous experience, in the sense that Lock or Hume or Moore or Russell or Ayer would posit, that doesn’t make the sentence as a whole based on observation; to suppose otherwise would be to commit the fallacy of composition, which you’ve repeatedly run afoul of.) Look, I’m a logical positivist, and when a logical positivist tells you that you’re being naive in your reliance on empiricism, it’s a pretty safe bet you’ve gone off the deep end. dhastork, I’ve responded to all that nonsense too many times to burden this thread anymore with my responses to you. |
“Look, I’m a logical positivist, and when a logical positivist tells you that you’re being naive in your reliance on empiricism, it’s a pretty safe bet you’ve gone off the deep end.” LOL. |
DKL, I believe that you just don’t really have any real knowledge about the climate system and the way in which our models are derived. For that matter, you have not demonstrated to anyone any scientific knowledge whatsoever. Your cowardly refusal to debate the science in terms of scientific facts and evidence only indicates that you have hardend preconceived notions and a very closed mind. |
Okay DKL, what evidence do you, as a self-proclaimted logical positivist, have that we as scientists do not base our models on past behavior of a system? Show me a paper on climate, preferable, since that was the genesis of this post, that’s made it through peer review that isn’t based on observations somewhere. You propose as an example of a scientific generalization “Bricks wrapped in animal fur have greater tensile strength than bricks wrapped in canvas.” This would barely qualify as a hypothesis and is certainly not a scientific generalization. Why would this be true? What previous observations do you have that suggest this would generally be true? What data can you share with the rest of the world that leads you to this conclusion? You do not understand the way science works, which is very obvious from your descriptions of the supposed workings of science. You don’t even seem to understand the basics of the scientific method. You have three working scientists telling you the way science works, explaining again and again the way we verify our results, the way we come up with our ideas to test, and you persist in telling us we’re wrong. What arrogance! |
Kristine N Okay DKL, what evidence do you, as a self-proclaimted logical positivist, have that we as scientists do not base our models on past behavior of a system? First of all, other people here can actually verify that I’m a real logical positivist, and not just a self proclaimed one. Second of all, I never said that you don’t base your models on the past behavior of a system. I said that a model needn’t be based on past behavior to be scientific. You asked for an example, and I gave one. You’re the one who has been asserting that models have to originate from such and such a place to be scientific, and that’s just preposterous. Disparaging a model because of its source is tantamount to an ad hominem argument. What makes a proposition scientific is that its liable to falsification by either critical scrutiny or empirical results. Kristine N: You propose as an example of a scientific generalization “Bricks wrapped in animal fur have greater tensile strength than bricks wrapped in canvas.†This would barely qualify as a hypothesis and is certainly not a scientific generalization. It’s a testable hypothesis, and a generalization. It could be more specific, but that’s a matter of degree. I could say, “The difference in tensile strength between a brick wrapped in fur and brick wrapped in canvas is (when the bricks have the same surface area and are of equal mass) inversely proportionate to the square of the mass of the wrapping.” That one is easier to refute in the abstract, but in practice about the same. Kristine N: What previous observations do you have that suggest this would generally be true? What data can you share with the rest of the world that leads you to this conclusion? None. Please note that I expressly indicated that this has “no relationship to past observations.” And later said, “it’s not based on past observation.” That, of course, is the entire point. I made it up off the top of my head, as I indicated when I preceded the statement with the claim, ” I can make any number of generalizations up that have no relationship to past observations: Here’s one off the top of my head.” That means that it’s made up. I don’t know how I could have been more clear. You continue to ask questions like the one I site, and to make assertions like the one I site. You’re clearly very poor at making judgments based on observations. If you were better, you might have shown enough judgment to avoid asking such irrelevant questions. It does, however, provide insight on why science is in its present sorry state. Kristine N: You do not understand the way science works, which is very obvious from your descriptions of the supposed workings of science. You don’t even seem to understand the basics of the scientific method. You have three working scientists telling you the way science works, explaining again and again the way we verify our results, the way we come up with our ideas to test, and you persist in telling us we’re wrong. What arrogance! Let’s actually tally the score here: 1. You and your “working scientists” were the ones who insisted on arguing about whether diminishing returns was an asymptotic pattern, when you were (a) wrong, (b) dwelling on the irrelevant (as I repeatedly indicated, and (c) showing an astonishing willingness to make bold and unqualified statements about areas that were outside of your area of expertise and about which you were too lazy to consult sources beyond what you could find with google. 2. You and your “working scientists” were unable to explain how causation worked, but willing to bicker about it endlessly until I provided a definition compelling enough to end the bickering and show that you guys were referring to causation incorrectly. 3. You and your “working scientist” demonstrated a basic ignorance of how mathematical systems work by (a) mischaracterizing how Goedel’s theorems work, and (b) insisting that the different answers for 0/0 are the result of paradoxes. 4. You and your “working scientists” still cannot demonstrate a basic grasp on how securities models work, in spite of having been provided with a clear example. I could go on and on. That’s just what I got from a quick scan of the various arguments that we’ve engaged in. Scientists are supposed to give the impression that they’re both cautious and judicious, as well as willing to weigh the merits of people’s arguments without prejudice. But you “working scientists” continue to make overly brash assertions that you can’t back up, and have little more than snide things to say to those who disagree with you. If the opinion of you “working scientists” mattered, then why can’t you demonstrate it in an argument against someone as unschooled in the ways of science as myself? You want to come here, lose every argument, and then end by saying it doesn’t matter whether you win the arguments, because you’re a “working scientist” and I’m not. |
DKL–you still haven’t said a single scientific thing. you “working scientists†continue to make overly brash assertions that you can’t back up, and have little more than snide things to say to those who disagree with you. You sure you aren’t talking about yourself here? |
Why do you Mormon Mentality people tolerate a troll as a permablogger? I’m getting a little tired of reading, “no, you’re stupid,” in 2000 words or less. DKL, stick to bashing Microsoft or making jokes about dead women, and let the scientists get back to work. Aside from attacking the philosophical grounds for climate-modeling you have offered no evidence that global warming is not occurring, and no meaningful contribution to the central question of this thread–”What should we as Mormons be doing in our personal lives to reduce our contribution to the problem?” |
nofolete, We actually have a mechanism for readers to get rid of a permablogger. You can vote him out ala Banner of Heaven. In fact DKL was the subject of such a procedure at that blog due to his numerous rude comments towards Miranda. |
arJ, DKL isn’t attacking me or my career (that would be far too easy I’m afraid). I am also a fairly new presence on this blog, primarily limiting my comments to this thread, which happens to be a subject of particular concern for me. If kristine N or dhasterok were to move to have him banned I can’t guarantee I’d support it. I just wish he’d relinquish his threadjack. Maybe he should write his own post about why positivism kicks a$$ and let the debate rage over there. |
nofolete: Why do you Mormon Mentality people tolerate a troll as a permablogger? Because I know everything about everything, of course. Who wouldn’t want that? nofolete: I’m getting a little tired of reading, “no, you’re stupid,†in 2000 words or less. I’ve been reasonably polite — at least more polite than any “working scientist” who’s participated. Those “working scientists” have consistently sacrificed substance in the interest of making shrill or snide comments. For my part, if I want to say that you’re stupid, I can do it in a lot less than 2,000 words. nofolete: you have offered no evidence that global warming is not occurring All I’ve ever pretended to show about global warming is that there is no scientific basis for considering the climate models to have predictive validity. Nobody has laid a finger on this. nofolete: Maybe he should write his own post about why positivism kicks a$$ Positivism has nothing to do with global warming. In fact it’s the simplistic approach characterized by scientists who discuss global warming (as you’ve seen here) or predicted that Strategic Missile defense is impossible, or predicted that there would be a heterosexual AIDs epidemic that gives positivism a bad name. That’s what’s commonly labeled positivism. When I say I’m a logical positivist, many people automatically associate me with the kind of moronic approaches to science like the ones that you’ve seen here embodied in the approach of the “working scientists” — and I take great pains to distance myself from it. |
Positivism, or empiricism, as I understand it, means you only believe a thing when you have proof, right? So, as DKL appears to be applying the principle of positivism to climate change we shouldn’t believe climate models because the future hasn’t happened yet and that is the only acceptable way to verify the validity of a climate model. Guess what DKL: scientists have been running climate models, with much simpler physics since the 1950′s. As it turns out, our climate models from the 50′s predicted what we see today. We understand the basic physics of the significant climate forcings well enough to predict global climate reasonably well and any improvements in our understanding at this point simply reduce the error bounds on our estimates–they do not change them. There are no climate modelers who predict increasing atmospheric CO2 concentrations will have no impact on global temperatures; there is nobody who studies this problem who thinks climate will cool. All our arguments in the scientific community are over how much Earth’s climate will warm, and what impact that warming will have on other aspects of the climate system (sea level, precipitation, seasonality of precipitation, storm freqency and intensity, local effects, etc.). The projected consequences of climate change, even if we take action now, are significant, and are projected to be much more severe if we take DKL’s suggested course of “waiting until the models are verified by time.” We have to make decisions based on incomplete and uncertain information all the time. Without some magic crystal ball we won’t know what will happen until it does, and the possible consequences of this particular issue are significant enough I think it sheer stupidity to ignore the warnings. |
Kristine, positivism entails certain claims about what proof constitutes and typically includes the idea that proof entails a kind of certainty in at least some of its parts. However there were many different thinkers under the label of positivism. Very few philosophers accept positivism. Most think it was killed by Quine, Popper and Kuhn (although one could argue that two of those were closely tied to positivism and merely modified it somewhat) I tend to think positivists set the bar too high for what constitutes knowledge or verification. So I’d not give DKL’s concerns that massive a concern. I think some climatologists do make some questionable assumptions at times though. (Although not being a climatologist beyond studying some basic metrology and atmospheric thermodynamics I’ll admit to being ill equipped to analyze the details of climate physics) |
Kristine N: So, as DKL appears to be applying the principle of positivism to climate change we shouldn’t believe climate models because the future hasn’t happened yet and that is the only acceptable way to verify the validity of a climate model. Actually, no. This is not an argument that is tied to positivism. Moreover, you’ve botched my argument yet again. My argument is rather simple, and it’s discouraging how little effort you’ve made to grasp it. I’ve said it too many times to make it useful to count: No amount of vetting of models against known data sets invests that model with predictive validity. The models predictive validity is tested only when it confronts data that is unknown at the time that it’s formulated. I’ve given an informal set-theoretical proof of this in comment #113. I brought up the fact that I’m a positivist to (a) poke fun at you, and (b) to emphasize the irony that your approach is indicative of the brand of over-confident, naive scientism that is most often attributed to positivists, and that I frequently have to distance myself from. (There are, no doubt, positivists that act this way, but reputable positivists (Ayer, Carnap, Quine, Schlick, Reichenbach, et. al) have a reasonably sophisticated view.) Kristine N: scientists have been running climate models, with much simpler physics since the 1950’s. As it turns out, our climate models from the 50s predicted what we see today. Of course they have, Kristine. Climate models since the 50s have predicted nearly every possible climate result. That’s why all the trendy scientists in the 70s were bemoaning the coming ice age. That’s why global warming never became a threat to sound policy-making decisions until the early 1980s — in spite of the fact that the theory of anthropogenic global warming originated 100 years earlier and made many bogus predictions. The primary source of early (1980s-era) global warming nonsense was the Hadley Centre for Climate Prediction and Research, created at Margaret Thatcher’s personal instigation to churn out anti-coal science; this was part of her effort to reduce the UK’s dependency on coal, which was (in turn) part of a broader effort to power of labor unions. There’s a scam where you send out 1000 letters via mail, 500 that say that the stock will go up in the next month, and 500 that say that stock will go down. If the stock goes up, you take the group of people that received the 500 saying it would go up, and you send 250 a letter saying that the stock will continue to go up, and send 250 a letter saying that the stock will go down. If the stock then goes down, you take the 250 people who received the last letter saying it would go down, and send 125 a letter saying that it will go up, and send 125 a letter saying it will go down. Then, the next move the stock makes, you have 125 heavily qualified leads. Until recently, this is how climate modeling worked, except you don’t send letters, you just announced how many successful models you have left. Nowadays, scientists just exclude models that fail to predict warming, dub this a valid assumption, and then they use the accumulated models to compute probably ranges of climate changes over time. Clark: I tend to think positivists set the bar too high for what constitutes knowledge or verification. So I’d not give DKL’s concerns that massive a concern. That’s brilliant, Clark. Let’s throw away ideas just because they are espoused by someone who belongs to a certain school of thought. In any case, nothing I’ve espoused here is directly related to a uniquely positivistic outlook on science. |
DKL, I appreciate your dogged allegiance to a 150 year old philosophy that makes no room for your personal spiritual experiences. Ontological messiness aside, I have two questions: 1. In your personal life, do you do anything to mitigate global warming, or (since it’s a related issue) to conserve energy or encourage our “energy independence” as a nation (aside from building a coal-fired power plant in your backyard)? 2. How come you use Safari? That’s not a moral judgment or anything, just thought I’d ask. |
“No amount of vetting of models against known data sets invests that model with predictive validity. The models predictive validity is tested only when it confronts data that is unknown at the time that it’s formulated.” And how exactly is this different? |
PHILOSOPHY: SCIENCE: DKL, GET OVER YOURSELF! let the scientist work and keep the damn philosophy out of it. |
The line between science and philosophy is much blurrier than it appears. Lee Smolin wrote an influential piece last year that argued that one problem science has at the moment is that scientists don’t pay enough attention to philosophy whereas in the past most scientists were also philosophers. I think part of this is due to the influence of John Dewey’s Instrumentalism which was very influential on American science. Also the way that our University education system tends to teach – if philosophy is actually taught to scientists it is rarely in a form that is relevant to them. |
That’s brilliant, Clark. Let’s throw away ideas just because they are espoused by someone who belongs to a certain school of thought. Thanks. I thought it was nearly as funny as your use of positivism… |
I took the time to wade through this thread, skimming judiciously when required… I’ve also read numerous other threads on the internet about global warming, numerous newspaper and magazine articles, and chased down numerous citations to try and learn more. In all of that reading I can’t recall ever hearing the thought that regularly occurs to me when thinking about global warming: why is it necessarily a bad, even a terrible thing? Global warming, whether one believes in it or not is always portrayed as a disaster in the making. That would only be true if we believed that our current world climate is the best of all possible climates. Do the doomsayers really believe that? And if they do, why? What rational, scientific arguments support that view? I certainly like the climate I live in, but it seems reasonable that a different climate might just as easily be better than worse. Certainly global warming will hurt specific populations, such as those who live at sea level. And I realize that a large percentage of the earth’s population lives in the region that will be affected by rising sea levels; but the sea won’t rise tsunami-like overnight and swamp them. Humans are remarkable adaptive, there will always be a shoreline and people will move and redistribute themselves when forced to do so. Looking at the planet overall, is it a given that the total impact of global warming must be negative? |
KLC – depends on your perspective – if you are someone who thinks that you have to think in terms of the entire earth’s history, we humans are just a blip and so this is not that important in that context. In the short term, if sea levels rise they will not rise catastrophically as you mention. Therefore, countries like the US can have time to build dikes around NYC for example or such things as that (however, we would probably have to abandon Florida – not sure you can dike the whole state). However, the problem is with the hundreds of millions who live in poor countries who cannot afford to build dikes – what will they do? They will overwhelm these governments and set off all kinds of problems such as new global disease epidemics. In addition, the broader problem is what happens to our current economic system. If the breadbasket of North America shifts into Canada, then the US just lost significant wealth, not to mention the migration of tropical diseases into the southern US. These types of things will cause significant problems for the world. Finally, significant species will go extinct due to the process. So again it depends on your perspective – if you are don’t care about the near term then, yes, the earth will recover at some point in the future after all of the oil (and probably humans) are dead. However, short-term the pain is tremendous. |
Devyn, your answer is full of ifs and other suppositions. How certain are we that rising sea levels over a span of 100+ years will destabilize governments? How certain are we that rising sea levels will cause global disease epidemics? How certain are we that food production will shift to Canada? There is solid evidence to support the hypothesis that human activity is contributing to global warming. But I see little evidence supporting the assumed disaster that warming will bring; my impression from most of the literature is that I’m just supposed to accept this coming disaster on faith. The UN report that was recently released tells us that global warming will continue in spite of any human intervention, including absolute cessation of using fossil fuels. Given that, shouldn’t we be putting more effort into understanding its effects and dealing with its consequences instead of arguing over symbolic gestures like compact fluorescent light bulbs and cloth diapers? |

How certain are we that rising sea levels will cause global disease epidemics? How certain are we that food production will shift to Canada? Without evidence, proponents of drastic measures to curtail global warming are chicken littles crying that the sky is surely falling. There is solid evidence to support the hypothesis that human activity is contributing to global warming. But I see little evidence supporting the assumed disaster that warming will bring; my impression from most of the literature is that I’m just supposed to accept this coming disaster because, well because things are going to change, and isn’t that terrible? Whatever happened to those cherished modern arguments against conservatism that change is good and we shouldn’t be afraid of it? The UN report that was recently released tells us that global warming will continue in spite of any human intervention, including absolute cessation of using fossil fuels.

I tried to stop my first reply in order to make some changes, apparently I was too late. |
KLC–not that I’ve read it, but apparently Jared Diamond’s book, “Collapse,” goes into quite a bit of detail on cultures that have collapsed due to ecological missteps. |
nofolete: DKL, I appreciate your dogged allegiance to a 150 year old philosophy that makes no room for your personal spiritual experiences. Yeah. Because newer is better. Where were you when I was arguing against the King James Bible. nofolete: In your personal life, do you do anything to mitigate global warming… ? I use Beano. nofolete: How come you use Safari? That’s not a moral judgment or anything, just thought I’d ask. I don’t. I use OmniWeb. anonforthisone, I’ve long since gotten over myself. Might I suggest that you get over me? Besides, it’s fallacious to dismiss my arguments based on my background. And it’s ridiculous to dismiss them based on a dictionary definition of a word that peripheral to the conversation. And, for the record, I’d be happy to leave scientists alone if they were willing to leave me alone. Instead, they’re endlessly trying lord their moral outlook over me and others others by leveraging their credentials to promote political positions. |
DKL, thanks, that’s all I wanted to know. I hope you manage to stay in Milton long enough to enjoy your beach front property. And, for the record, I think your generalization accusing scientists (not all of whom are liberal) of political motivations is somewhat disingenuous, and taking the easy way out of the debate. But then, in your mind you won a long time ago. I’ll leave you to your politics and hope the rest follow suite. If you ever care to take on the KJV again I’ll be happy to throw my scant weight into the effort. Omniweb makes more sense. Safari had me kinda thrown for a loop. I was afraid I’d read you wrong. |
Clark–usually we just talk about statistics and basic scientific method or occam’s razor, or just plain old logical argument and you’re right: we don’t delve too much into philosophy. In part I think that’s because new ideas are so much fun to discuss. I’m not sure I would agree with you that this lack of philosophical teaching causes problems in science, but then I’m a product of (and supporter of) the current system. Where do you see gaps in science philosophy? And by the way, the most obnoxious part of this whole discussion for me has been watching you and DKL throw around references to complex ideas with a single name. I realize scientists can have the same tendency, but in this discussion all three of us who’ve been involved (dhasterok, pggettings, and myself) have attempted to explain the concepts at issue in a straightforward manner. You philosophers haven’t show the same courtesy. If you are truly serious about having a discussion of the relationship of philosophy to science, may I kindly suggest you at the very least provide a link to a webpage explaining the concept, or spend a sentence or two clueing the rest of us in? |
KCL & kristine N, my #148 was based in part on Diamond’s arguments from Collapse. KCL, I think one of the major concerns is the massive uncertainty. Climate scientists do their best to predict what’s comming, but their models can’t predict the reactions of and consequences to a global civilization. We’ll have to deal with massive movements of population, destruction of property and infrastucture, changes in rainfall effecting arable land, desertification, acidification of the oceans effecting that ecosystem from the phytoplankton up. In my strictly unprofessional and amateurish opinion I think that a fair amount of warming is inevitable, and I certainly hope we can adapt. I also think that by rallying our efforts now and investing in new technologies, technologies that are lighter weight and more adaptive, rather than reinvesting in the old industrial solutions, that we might be able to soften the blow when it comes. If I were a businessman or venture capitalist I would think of the chance to adapt our civilization to a changing and uncertain future as the opportunity of a lifetime. |
Kristine N: [when we scientiests] have attempted to explain the concepts at issue in a straightforward manner. You philosophers haven’t show the same courtesy. This is a cop out. In my case, I do not believe that this could be farther from the truth. I have repeatedly offered examples, explanations, and definitions. My description of how causes work (in the paragraph beginning, “Start with the salient factors..” in my comment 222) was lucid enough to end the argument — and in my favor. Rather than describe how I think that securities models worked in the abstract, I actually described a working, successful securities model that is unencumbered by the factors you allege would prevent it from being a purely statistical model. (in the paragraph beginning, “On to the model…” in my comment #229). When you got caught up arguing in the abstract about whether one could generalize based on things that were not in his past experience, I offered a simple, lucid example of a falsifiable generalization that was not based on past experience. (The general formulation in my comment #238, and the more specific formulation in my comment #252, in the paragraph beginning “It’s a testable hypothesis…”) When you all were caught up with 0/0, I pointed to a set of international standards that define specific working alternatives to the solution provided in standard algebra (in my comment #217, in the paragraph that begins, “The multiple answers are not paradoxes…”) Please allow me to offer a characterization of this conversation as I have seen it: I make an argument, and that argument (or the verbiage in it) is used as the basis to attack my background, argue that it’s different from science, and therefore not making good arguments about science — all to avoid responding to the arguments as arguments. (As was the case when you all incorrectly guessed that I’m an economist, and as it is the case now that you’ve guessed that I do philosophy.) You all use Google to come up with some amount of stuff that you can describe in order to dazzle me with all types of stuff that you think will strike my naive mind as strange or confusing. (As was the case with dhasterok’s and PGGettings’ bickering over diminishing returns or dhasterok’s introduction of the 0/0 issues and Geodel’s theorem; this was also the case with PGGettings’ (failed) attempt to describe how securities models work.) You all saturate the dialogue with remedial discussions of elementary scientific ideas that have never been at issue; for example, PGGettings long-winded and superfluous description of why models “are useful, tricky, and the basis for everything we know and love” and how systems should be defined. In the meantime, you carry on multiple arguments about issues that do seem to fall directly under the area of your expertise (like the nature of causes), and yet you demonstrate that you do not have a solid grasp on them. PGGettings even went so far to say that my ideas on causation are “sufficiently silly to get [me] permanently categorized as an idiot/politician,” though in his next comment he ended up stating his agreement with them. (Though he still gets it wrong by trying to identify baseline conditions with initial system states, probably an attempt to save face by bickering over words.) Finally, you give up any pretense of rationality and just appeal to credentials, saying, “You have three working scientists telling you the way science works, explaining again and again the way we verify our results, the way we come up with our ideas to test, and you persist in telling us we’re wrong.” It’s been some time since I did any serious study of any of these matters, and I’ve recited all of this stuff from memory (except the quote from Sowell). I can’t always recall the exact preferred verbiage, but I think I’m doing well enough on the concepts. At any rate, I haven’t made any glaring errors (as opposed to, say, dhasterok). I’m not trying to “throw around complex ideas” using a “single name.” I am, however, expecting those with whom I’m carrying on a dialogue to abstain from bickering over word choice. I challenge you to identify examples of I’ve been obnoxious by throwing around simple names to describe complex concepts that I’m unwilling to describe in concrete terms. |
dkl–I wasn’t necessarily talking about you. |
It’s true that little of our scientific educations deals directly with philosophy of science or the different theories about philosopy; however, we are taught basic concepts from philosophy through hypethesis testing and theory development. The most common approach to science today involves the concept of “multiple working hypotheses,” where a number of possible explanations are developed based on current knowledge and a set of rigorous tests are proposed and performed that will eliminate possibilities. Many of the concepts of philosophy of science that have been developed in the past 2000+ years are so subtly included that most scientists probably don’t realize what we’re being taught. I disagree with kristine N’s claim that we aren’t taught philosophy of science, though I can see her confusion since it is not directly addressed as philosophy. DKL–I find it interesting you believe you won most or all of these arguments. We apparently disagree over many definitions (for example: causation) and the scope of others (example: diminishing returns), not to mention your abysmal understanding of the way science is actually done. In my mind, and from the statements of the other scientists visiting this forum, I believe I have as much right to claim victory. Many of the comments you claim were beside the point were not in direct response to you, DKL, but explanations offered for others following the conversation who might be interested in how we scientists arrive at our numerical models. One of the concepts you’ve shown the most ignorance of is the difference between a numerical model and a natural model (theory). You are misapplying philosophy of science for developing theories to a numerical model. Numerical models, like those used for climate change, are predictive tools based on theories (natural models of science), like blackbody radiation and the ideal gas law among others, which are developed independently using the concepts of philosophy of science. Securities models are not based upon fundamental, physical theories in the same way climate models are. Thus, your arguments for invalidating climate predictions based on the inability of securities models to predict the future are invalid. |
According to Webster’s Collegiate Dictionary: Paradox–a self-contradictory statement that at first seems true OR an argument that apparently derives self-contradictory conclusions by valid deduction from acceptable premises. Thus, 0/0 is a paradox. Also, 0^0 = 1 is a paradox that, while apparently resolved, is still a paradox. |
dhasterok, I think that it’s great that you deny that I won all the arguments I take credit for winning, but you fail to identify a single example. And FYI: All models (in the sense that we have discussed) are numerical. The only question is where the numbers come from. I want to clear something up at this point, something that Clark brought up. Specifically, there’s nothing especially physical about these sacrosanct physical laws that you talk about. Take Newton’s first law, the law of inertia. It states that an object in motion will remain in motion at a constant velocity until some other object disturbs it. It is doubtful whether, in the entire history of the universe, any object has ever moved at a constant velocity in this fashion. It has certainly never been observed to have occurred. Clark has pointed to the ideal gas law as another example of a law that is based on non-physical occurrences. In fact, any very useful law can easily be shown to have the same problems. Specifically, these “physical laws” that you exalt above all others do not gain their usefulness because describe things that actually happen. They are useful because, when applied, they have useful results. The working assumption that you have that physical laws are somehow different from axioms within any other systems is poppycock. Your position with regard to 0/9 is also preposterous. It appears to you to have some plausibility only because you’re terribly ignorant, and you’re trying to use equivocation to contrive a paradox. Quite simply, there is nothing contradictory about two altogether independent systems adopting mutually exclusive policies for handling numbers. IEEE 754 is no more bound by the results of standard Algebra than Newtonian physics is by Euclidean geometry. To put it in the terms of your sited definition (which actually supports my position and not yours) you must derive the contradiction “by valid deduction and acceptable premises.” The premises of IEEE 754 and standard Algebra are mutually exclusive. Thus, the premises of standard algebra are not acceptable within the system created by IEEE 754, and vice versa. So you have no acceptable premises from which to draw your contradiction, and therefore no paradox. (At this point, I must express astonishment at how little you seem to think about the things you say.) Moreover, you state very plainly that you believe that there is a real answer to 0/0. In doing so, you demonstrate a fundamental misunderstanding of how mathematical systems work. |
dkl–are you trying purposely to misunderstand what other people argue? dhasterok said 0^0 = 1 has an answer. He did not, as you claim, say that 0/0 has an answer. |
I do not believe that I’m purposefully misunderstanding anyone. In fact, I think that I’ve provided a rather strong reading of his statement:
My response:
To which dhastork responds:
Based on this, if you find it unreasonable to conclude that dhasterok believes that there should be one and only one answer to 0/0 regardless of the theoretical framework in which it is addressed, then I don’t know what to tell you. To tell you the truth, I don’t think that dhasterok could be much clearer on the matter. In any case, once again, it’s pretty easily demonstrated that you’re wrong. This is getting pretty tiresome, how you “working scientists” are continue to advance such low-quality argumentats. |
It’s amusing when you finally start to talk real science you show your true ignorance. Physical laws, like Newton’s first law, the ideal gas law, and Hooke’s law, etc., all reproduce precisely what we see in nature. The ideal gas law predicts exactly what we see in classical limit (i.e.–the world we live in) unless the particles get too close, temperatures get too high, or there’s a chemical reaction between the particles, at which point the more fundamental quantum-mechanical descriptions of behavior describe what we see. The ideal gas law can be derived from quantum mechanics when classical scales are imposed. There is a physical reality to these laws that does not arbitrarily change. Whatever happens on the quantum mechanical level when particles interact at a specific temperature and density to produce the pressure we can measure does not matter. If you change the pressure, then the volume or the temperature has to change (in spite of what happens in The Day After Tomorrow). In the limits beyond the quantum mechanical description it’s still a physical process, whether we can describe it in terms of mathmatics or not. If the question you’re really getting at is, “does our universe really exist physically (i.e.–can we really touch it) or is it all a figment of our imagination?” I would say this–this is nonsense, and is why philosophers make terrible scientists. We don’t actually live in the matrix. |
dhasterok: Physical laws, like Newton’s first law… all reproduce precisely what we see in nature. It really is tiresome how repetitively and simplistically wrong you are. This is the very embodiment of that untenable and naive positivism to which I’ve referred repeatedly. With regard to Newtons law, the fact of the matter is that we don’t have an example of any object maintaining a constant velocity because nothing interferes with it — it’s never been observed to happen. And since it has never been observed to happen, it is simply impossible for the law to be reproducing “precisely what we see in nature.” All we know for sure is that Newton’s law of inertia proves to be quite a useful axiom, and this much is conventional wisdom. Once we start to explain exactly why it is useful, we lose consensus and we begin to get widely divergent opinions. But the fact remains that no object has ever been observed to maintain a constant velocity when nothing interferes with it. You’ve got it the wrong way around: We adopt the laws because they produce useful results. We don’t adopt laws because they are true, and then wait for the useful results to follow. Besides, taking my model for securities trading in my comment #228 (laid out in the paragraph beginning “On to the model…”), it can be said that it describes exactly what we see in nature as well. There’s just nothing special about a “physical” law as opposed to any other observed, quantifiable regularity. |
Wow, you are really amusing. Sounds like you’re arguing that if a tree falls in the forest and there’s nobody around to hear it, does it make a sound? This is absolutely absurd. We know things continue to happen, even when we’re not observing, because we can measure them at two points in time and use physical laws to describe their motion in between. This is true whether we are observing or not. For example, planetary movement is the same whether we are watching or not. There is a physical reality to the mathematical description that does not change. Observable, quantifiable, and truly regular are all features of a physical model, and if your securities model fit all three of these it too would be a physical model. Because securities trading is not regular (i.e.–shows unpredictable behavior as a result of individual, personal choices, which can be significantly different from person to person) it can not be considered a physical model. We adopt laws because because we have observed that they are true and then we extend them to new applications. Scientific theories are not numerical, though they are frequently mathematical in nature. Numerical models are based on approximations to the mathematical model run on a computer. |
dhasterok, We don’t actually live in the matrix. I’m less and less convinced that you can prove that. :) |
dhasterok: Wow, you are really amusing. Sounds like you’re arguing that if a tree falls in the forest and there’s nobody around to hear it, does it make a sound? I don’t follow you. You state that laws are based on precisely what we see in nature. I point out that we don’t see anything resembling a precise instance of Newton’s law of inertia. Exactly what does the tired cliche surrounding about unobserved tree-falling have to do with it? As I stated earlier: “It is doubtful whether, in the entire history of the universe, any object has ever moved at a constant velocity in this fashion. It has certainly never been observed to have occurred.” From the truth of that statement (which you don’t seem interested in refuting), it follows that your supposition that this law is based on precisely what we see in nature is plain wrong. If, through the course of this exchange, you had been able to demonstrate even once that you were reasonably well-informed about any of the issues that we’ve discussed so far, then I’d think maybe you had some grounds for the snide tone that you repeatedly adopt. But you really shouldn’t be so cocksure when you’re putting yourself into situations where you’re bound to come out looking like an utter moron. dhasterok: Because securities trading is not regular (i.e.–shows unpredictable behavior as a result of individual, personal choices, which can be significantly different from person to person) it can not be considered a physical model. Here we go again: Of course it’s not a physical model. That’s the entire point. You’re assertion that personal choice has anything to do with it runs afoul of the fallacy of composition, and this is about the 3rd or 4th time that a “working scientist” on this thread has reflexively made this error in reasoning (again, the quality of thinking on your part and on the part of your colleagues is astonishingly low). Here’s why your reasoning involves the fallacy of composition: Each individual trade involves a personal choice, but the aggregate of all trades is not the result of personal choice. Moreover, the statistical behavior of the aggregate can be used to automatically trigger buying decisions regardless of what triggered any given trade within the aggregate. Besides, you evidently did not read the paragraph that scopes out the sample model (in spite of the fact that I linked to it in my preceding comment). It has nothing whatever to do with personal choice. I’ll tell you what: You explain to me where personal choice enters into my model, and then we’ll talk. dhasterok: We adopt laws because… Given how wrong you’ve been about everything else that you’ve asserted (causation, Geodel’s theorem, the “real” answers to 0/0 and 0^1, whether different answers for 0/0 constitute a paradox, whether diminishing returns is necessarily asymptotic, etc.), I think that you owe me an explanation as to why you think you still have the credibility to make such assertions. |
I just wonder why people are asking our leaders to give a stand on GlobalWarming.Will they obey if the Prophet speaks something about it? Or will they just use it against us? Our leaders are more concerned with the evil that is engulping our society and thatis greed , lack of human respect ,intolerance,immorality and all other things that will destroy our spirits more than our bodies.If humanity will just read the scriptures and listen to the word of God,I believe that God will all bless us and all will live in peace and harmony regardless of our faith and religious persuassion. |
Fun thread–heated as it is. It’s funny how the rise of both internet use and global warming seem to correlate so well. |
Jason – the reason why it is important for the Prophet to speak out is that most Mormons don’t give a hoot about a subject unless the Prophet tells us it is important. I am glad that you believe that if we all read and pray we can have peace and harmony. I don’t necessarily see it that way. JKC – they are not suppositions they are projections made by scientists, not random guesses by lay persons. Read the scientific articles and it will give you some idea of the chaos that could ensure. It is relatively simple to calculate how much ice there is in the world and how much the sea would rise if it melted as well as the effects on diluting out salt, changing temperatures, etc. So perhaps they are suppositions to you, but they are much more than that to a scientist. |
Devyn S., Do you believe the prophet failed by not speaking out on global cooling back in the 70′s? |
DKL–as I recall the origin of this economic model/physical model debate was from your claim that because a securities trading model can not be used to predict the future, no models can be used to predict the future. So, essentially you are attempting to prove by induction that since it’s true for one, it’s true for all. How exactly does this claim not also run afoul of the “fallacy of composition”? Oh right, ’cause YOU said it. If, through the course of this exchange, you had been able to demonstrate even once that you were reasonably well-informed about any of the issues that we’ve discussed so far, then I’d think maybe you had some grounds for the snide tone that you repeatedly adopt. But you really shouldn’t be so cocksure when you’re putting yourself into situations where you’re bound to come out looking like an utter moron. Again, it sounds like you’re talking about yourself here. |
Kristine N: because a securities trading model can not be used to predict the future, no models can be used to predict the future WTF? I never made this argument. I never even came close to making this argument. I’ve restated my argument so many time that it can’t possibly do any good to repeat it here, and I’ve never even come close to saying anything resembling this. I’m now starting to believe that you’re not just attacking straw man arguments, but you’re just aren’t smart enough to understand. Kristine N: Again, it sounds like you’re talking about yourself here [when you talk about the chronically ill-informed]. If you could name even a single example, then this claim wouldn’t ring hollow. You have yet to identify as area that we’ve addressed in this discussion in which I proven to be less than reasonably informed. I’ve specifically identified several instance in which you’ve gone off half-cocked and the results have been unfortunate. I’d started out thinking that you may not be intellectually honest, because you just want to move on when the exchange doesn’t go in your favor, and you’re unwilling to say things like, “Yeah, I guess you were right that since Geodel’s theorem only applies to formal systems, it’s not directly relevant to science.” Or “Yeah, I guess you’re right that causes do require baseline conditions to be efficacious.” Or “Yeah, I guess you do have a reasonable and approach to how independent mathematical systems can contradict each other without leading to paradoxes.” Or acknowledgments like that in any number of areas where you’ve proven ignorant. But it’s becoming increasingly evident that you just don’t get it. |
Kristine: You philosophers haven’t show the same courtesy. For the record I’m a physicist. I only minored in philosophy. I don’t think I was throwing around terms that much – except for laughing at the positivism bit. |
So, Clark, if she wasn’t necessarily talking about me, and she wasn’t talking about you (what with you being a “working scientist” and all), then it remains to be seen who she’s talking about. (I was dying to tell her, by the way. I can’t believe you kept your silence for as long as you did.) |
281 – Jack – Not sure what you are talking about here on global cooling in the 1970s, unless it is a sarcastic remark intimating that you do not believe any of the science about global warming. But it would be nice if the GAs spoke out about consumption and the need to limit it. |

I still like you, Clark. |
Previously, on DKL Deathmatch: Kristine N: [DKL claims] that because a securities trading model can not be used to predict the future, no models can be used to predict the future DKL: WTF? I never made this argument. I never even came close to making this argument. Flashback to post 111: DKL: you get all of these climate models by computers that are written specifically to predict the past several decades of whether, and some scientists are stupid enough to accept the idea that there’s even the slightest probability that their predictions concerning the ensuing decades are correct. I’ll tell you what: Create a model that predicts with a reasonable degree of reliability every twist and turn of the New York Stock Exchange or any the major currency exchange markets or any commodity or commodity future or other derivative market. Then use that model to do real trading and see if it proves as predictive in the future as it did in the past. Kristine: Umm… |
Clark–I wasn’t trying to point a finger directly at you; you’re hardly the only person throwing around undefined terms, and I really didn’t want to antagonize anyone. I assumed the main problem was an assumption of common knowledge that isn’t actually common. Let me give you an example of what I’m talking about (and this is just from one of your more recent posts, and admittedly isn’t that bad): Lee Smolin wrote an influential piece last year that argued that one problem science has at the moment is that scientists don’t pay enough attention to philosophy whereas in the past most scientists were also philosophers. From this, I don’t know who Lee Smolin is, I have no idea what arguments he used to make his assertion, and I don’t have a reference for the piece he wrote, so I can’t even go and find out. It’s a little frustrating trying to be part of a discussion when people make these sorts of references without providing an explanation, or at least a reference to look up, to those of us who haven’t been exposed to the same information. |
Kristine, again: WTF? The quotation you site does not make the argument, “because a securities trading model can not be used to predict the future, no models can be used to predict the future.” It doesn’t even came close to making this argument. I’ve restated this part of my argument so many time that it can’t possibly do any good to repeat it here, and I’ve never even come close to saying anything resembling your statement, “because a securities trading model can not be used to predict the future, no models can be used to predict the future.” But, I am, if nothing else, accommodating, so here’s a very brief summary (for the last time, I promise): Known data sets are fine for vetting a model to see whether it’s worth testing against unknown data, but they don’t establish predictive validity. This is what I’m specifically referring to when I say (as you correctly sited): “you get all of these climate models by computers that are written specifically to predict the past several decades of weather…” How you can go from this to “because a securities trading model can not be used to predict the future, no models can be used to predict the future” is simply mind-boggling. Look, it would be bizarre enough for you to disagree with the rather obvious point that known data sets don’t establish predictive validity. But the problem is that you and your “working scientist” friends aren’t able to respond to the arguments advanced against your position, because (no matter how many examples I provide examples, and no matter how many times I restate the arguments) you seem to lack the requisite intellectual skills to grasp them. It’s becoming obvious to me why this conversation isn’t going anywhere, and why you continually fail to demonstrate a reasonable understanding of the principles we’ve discussed. I’m sure you’ve got tons of stuff memorized, but perhaps you should work on developing your skills of reasoning, generalizing, and analyzing. |
what with you being a “working scientist†and all Well, I don’t work in science anymore. (I did work at Los Alamos in the early 90′s though on nuclear fusion) But I’m a chocolate artisan. Not sure if that counts for or against things. (There’s a surprising amount of science in it all – my background has definitely helped) From this, I don’t know who Lee Smolin is, I have no idea what arguments he used to make his assertion, and I don’t have a reference for the piece he wrote, so I can’t even go and find out. Oh, I kind of assumed Lee Smolin was famous enough most scientists know him. He’s a very well respect theoretical physicists – arguably one of the most important in the field at the moment. He just wrote a fairly controversial book attacking string theory. His main field is loop quantum gravity. But he’s definitely one of the biggest names in science. Up there with Roger Penrose, Stephen Hawkings and a few others. I’d get a link to the oft quoted article in question but I’m kind of rushed right now. In any case, Google is your friend for issues like this. |
Whoops. That should have said, “but I’m not a working physicist anymore. I’m a chocolate artisan.” |
Something just struck me. The title “Mormons and Global Warming.” It seems that Mormons are pretty clean. If I’m keeping my yard clean and my house clean and trying not to waste, aren’t I contributing to the general health of the planet? A friend once said that she felt, at that time, the best she could do for the world is raise good kids. If everyone cleaned up their own back yard, maybe the environment wouldn’t be a problem. Although, here we are trying to be saviors on Mt. Zion, bring souls to Christ, redeem our departed dead, raise our children as saints, etc., etc., I would hate to add global warming to my to-do list. Why should we be the ones? |
Remember the prophet said that the dissintigration of the family would bring about the calamities foretold by ancient and modern prophets; NOT global warming. The issue of Global Warming is a distraction from the REAL illnesses of society. Yes, we should reduce greenhouse gas emmission but we should first reduce the illigitamcy rate and strengthen the traditional family and traditional family values. |
annegb- It all depends on how you take care of your backyard… David- Greed, lack of foresight, and disregard for human life and safety in the long term are some of the causes of both global warming, and the disintegration of the family. If people would expand the scope of their vision somewhat they might see that we can take care of both at once. |
But you didn’t answer me. If I’m taking good care of my stewardship, I’m helping with the environment, you know that’s true, you do…..I’m right, I’m right, you know it. |
David – I would agree with Nofolette. Global warming is another symptom of the problems you outlined. Once people care about themselves, their families and their society, the issues you speak about, as well as environmental issues like Global Warming will take care of themselves. Annegb – If you take care of your stewardship, the environment is part of that stewardship. That means keeping your yard clean and not destroying the environment – which would mean not wasting energy through various conservation methods and driving a green car or driving as little as you can. Why us? Well, we are told we are to take care of the earth in the Temple – my question would be why not us? |
Of course you’re right, annegb. It’s like saying “people should be nice to each other.” Duh. What does it mean to raise your kids well, or to take care of your yard? Beyond a few fundamentals the rest depends on your point of view. If one were to raise healthy, happy kids, but then judge their goodness by their financial success as measured by their conspicuous (and wasteful) consumption, I’d say that measure of goodness diverges radically from my own. Not that that’s what you think, it’s just a for-instance. Earlier you seemed to advocate inaction on environmental issues based on your belief in a long overdue second coming. Now you argue that goodness and cleanliness are somehow sufficient answers to our environmental woes. Those are excellent values. Sadly they are being applied to a broken system. What good does it do to flush your toilet and scrub your sink if they both drain into your drinking water? No amount of good will can solve a problem if one takes no action. To reiterate an earlier point, I don’t expect you personally to become an activist. But don’t argue against changing out incandescent light bulbs for compact fluorescents (or LEDs, since compact fluorescents contain mercury) just because nobody said so in General Conference. I realized that you haven’t argued against anything so specific, but that is one of the specific actions that anyone can take to reduce energy use and greenhouse gas emissions. Our effect on the planet comes down to our specific actions (many of which are easy to do, or to change), combined with more general principals, like a true moral compass. However, generalities alone are insufficient. |

from http://news.yahoo.com/s/nm/20070521/us_nm/schwarzenegger_climate_dc_1 Schwarzenegger, Utah governor join on emissions cuts California Gov. Arnold Schwarzenegger and Utah Gov. Jon Huntsman agreed on Monday to work together to reduce emissions of greenhouse gases, adding Utah to a growing coalition fighting climate change in the U.S. West. … “Like California, Utah has great snow for skiing, magnificent natural forests and a productive farming and ranching industry,” Schwarzenegger said in a statement. “So higher temperatures are an economic threat and we literally cannot afford to stand by and do nothing,” he said. Utah gets the lion’s share of its electricity from coal-fired generating plants. The Western Initiative calls on members to adopt a regional emissions cap and to develop a market-based cap-and-trade system. |
It isn’t an incovenient truth, it is an extremely conveinient lie. It is designed to cause government funding to flow to “study” the issue indefinitely. Just as negative news gets more attention than positive news. Alarmist science gets more attention and more funding than positive science. |
301- thanks for the update Chino. The number of things that have happened in this area is amazing over the last few months. It is good to see the government get behind it. 302 – Boyd – apparently you have not read any science on the subject – there is no conspiracy of scientists. Do you think the CIA killed Kennedy? Did we actually walk on the moon? Any other conspiracies you buy into??? |
Devyn, that’s not a fair response. There needn’t be a conspiracy in order for there to be systematic behavior — only a common set of incentives. For example, from 1950 to 1990, there were no killings in Chicago that were officially recorded as related to organized crime; one needn’t posit a conspiracy to explain that. |
DKL – you are correct – I was a little grouchy after being stranded in DC for 4 hours last night. To infer that scientists are purposely publishing misleading data is wrong. I have not met any scientist who is of that ilk, although I am sure they exist. The scientists I know are trying to forward the advance of knowledge and are usually very altruistic individuals. |
I agree that it’s wrong (and silly) to accuse scientists (as a group) of publishing misleading data. In an essay that Bertrand Russell wrote in the 1940s entitled “Are Scientists Scientific?” Russell notes that most of the scientists advancing eugenics in the early 20th century were Nordics of the professional class and that nearly all of the scientists arguing that men were smarter than women based on brain size were men. Russell, who was Einstein’s favorite philosopher, is grouped by many among the positivists. He was an atheist who took a view regarding the supremacy of science that most Mormons would consider quite extreme. Even he concludes that scientific findings that have political import should be greeted with skepticism. And, if you look at it, most of the scientists advancing global warming theory are left-wing academics. Is it any surprise that the policies that are thought to remedy global warming problem align perfectly with policies consistently pursued by the left wing of the Democratic party over the past 3 decades? Obviously, there was no conspiracy among Nordics to pass themselves off as the master race. Nor was there a conspiracy among men to use science to belittle women. And it is unlikely in either case that scientists knowingly published misleading data. But you’re taking a naive view of science if you’re not concerned about the overtly political nature of the global warming debate — even as the debate occurs among scientists who decry the propagandistic nature of (say) Al Gore’s film. Funny thing: almost all of the scientists who were claiming in the 80s that missile defense wouldn’t work were left-wing academics who favored disarmament. I predict, Devyn, that your “global warming” theory will go the way of “scientific” opposition to Reagan’s Star Wars program. |
DKL,
Uh, missile defense STILL doesn’t work, except with dummy rockets in highly controlled environments, just like it is in war, right? |
Dan, Gorbachev is on record as saying that Reagan’s Star Wars was the final straw that completely broke Soviet will and forced them to face up the the reality that they could not keep up with the West. That realization led to the breakup of the Soviet Union. In that sense, Star Wars worked. |
Mark, Star Wars may have worked as a political tool, but that’s not what I was talking about, and neither was DKL, as I read him. Technologically and scientifically, the missile defense system does not work. Not only that, but if I were any nation that felt the least bit threatened by America (and I think that today that number is far higher than pre-Bush), I would pay attention to what America was doing. The missile defense shield is no secret. It barely works under highly controlled environments. If it ever came to blows, I would ensure that my missiles thwarted the MDS by either employing enough dummy warheads to start that effectively take out the defense shield’s missiles, or introduce new technology of my own that will make my missiles avoid the defense shield. Or, do what terrorists do. Heck, why should I be stupid enough to go on a frontal attack against such a powerful state? There are far more effective ways of getting what I want out of America by simple, and very inexpensive attacks. |
DKL – I do not agree that Global Warming will go the way of Star Wars. I am willing to bet on this one. Speaking of bets, I did win our bet on the fact that Clinton would get re-elected, so you better be careful with me… |
Dan, Star Wars may be technology that remains on the horizon, but it’s no longer credible to maintain that Star Wars cannot work. That’s exactly what scientists in the 80s were saying; viz., that Star Wars technology is impossible. The fact that you’re ready to jump into the fray to throw up red herrings like this is characteristic of the fact that you’re more of an apologist for Democrat policy than Dan Peterson is for Mormonism. Is it out of place for me to suggest that you try to think for yourself? Devyn, I remember that bet. After a disastrous first 2 years and a string of humiliating defeats and reversals, Clinton made the most remarkable political recovery of 20th century American politics. Hat’s off to Bill Clinton, who proved himself to be a brilliant, tenacious, and quick learning politician. And congratulations on winning or bet. (The 90s was a fun decade for politics.) |
DKL,
I don’t appreciate the insults. It may actually surprise you, DKL, that people who don’t agree with you actually think for themselves. It is me, myself, and I who believes the “star wars” system does not work, based on the evidence I have seen. I really don’t care what the DemocratIC party has to say about it. |
Whether it works or not, the system is a waste of American space. None of the nations Bush is worried about are even remotely capable of hitting a US target. Nor are they likely to become so in the next ten years. Unless comrade Putin is correct and Bush really is pointing it at Russia… |
Dan, if you didn’t show such enthusiasm for parroting the Democrat conventional wisdom, your point might be more credible. Furthermore, repeating your point about whether star wars actually works demonstrates the gap in your thinking that represents either a fixation on the irrelevant or intellectual dishonesty. If you think otherwise, then please indicate which assertion of mine you think that you are disagreeing with when you exclaim that star wars does not currently work. And it won’t do to reply, “It was the statement of yours that I quoted in my comment.” Your assertion that star wars doesn’t work fails to contradict the statement of mine that you quote in your comment. As a matter of logic, my statement requires that star wars be absolutely impossible (as was charged by scientists in the 80s), and it does not speak to the issue of whether the current system is advanced enough to fit the bill. Seth, what is at issue is that scientists in the 80s asserted that star wars was impossible. I’m using it as an example (like Russell’s example of Nordic eugenicists and males extolling the superior intelligence of men) of politically motivated science that ends up repudiated by history for reasons quite different than those that overthrow old theories in the march of scientific progress. Whether star wars is a good idea is beside the point. |
DKL,
That assumes that the DemocratIC conventional wisdom is not credible. Being a Republic operative yourself, your statement is discounted as lacking credibility on the subject. Regarding the missile defense system, the operative word is “work” in your original statement. You said:
Your comment had no implication of impossibility, but rather that scientists in the 80s claimed the missile defense wouldn’t work. Well, they were right. “Work” is the operative word. Not “absolutely impossible.” But I don’t put it past Republic operatives to move goalposts when challenged. |
Dan, the fact that you’re still arguing is dumbfounding: Since there’s a common belief that Star Wars will work, whether it does work is altogether beside the point. |
DKL,
Sure, if you actively participate in the military-industrial complex. This is your bread and butter. Of course you’re going to believe it will work. Heck you’ll believe pigs can fly! |
Even scientists recognize that if research is allowed to continue, it will work. The disagreement is now over policy and budgeting. It’s mind-boggling that you think that you’ve actually said something relevant in this exchange. |
DKL, Remember, these are the same folks who thought of this. Yeah, some bright folks there at the Pentagon. |
Really? Which scientists not working for defense contractors, DKL? But to this point, I am essentially correct, DKL. In the 1980s, scientists believed the missile defense system would not work. They were right. Today, it doesn’t work. I am right. You’ve moved your goalposts yet again. No longer is it about whether or not they thought it couldn’t work in the 80s, nor “absolutely impossible.” Now, your goalpost is that scientists think it WILL SOMEDAY work. Well yeah, someday we’ll probably be able to do a lot of things we won’t now, DKL. That’s a very weak rebuttal, I must say, coming from you. |
If I’ve moved the goal post, it’s moved from declaring the weak proposition of theoretical possibility to declaring the much stronger proposition that it will be obtained if we pursue it. Since my assertions are becoming stronger, it won’t do to insist that I’m back pedaling. This is an example of why it just doesn’t work to use logic to argue with you. |
whatever dude. you keep living in your dreamworld. |
Dan, that link you put up in comment #319 – that kind of military thinking actually is interesting. Maybe that particular idea isn’t a good one – but I like it when the military or government looks for unconventional but non-violent means to deal with an enemy. |
danithew, Finding non-lethal ways to conduct warfare is a noble goal, if the tools you seek to employ have any sense of reality. That particular example shows the perverted thinking among military brass, that somehow homosexuality makes men weaker fighters. Ironic seeing that many in the military espouse Spartan principles. Heh. |
danithew – good point, but the amount of wasted money on things like this is ridiculous. Star wars has cost billions of dollars for what? Nothing tangible yet. If we had spent that money on other things, who knows what the benefits would have been. |
Dan – my impression was that the idea of this weapon was to put enemy soldiers into some kind of sexual frenzy that would make them drop their weapons and go after each other – a concept that I find rather amusing. Science has achieved many things that initially seemed strange, unusual or even stupid. I have no idea what the initial proposal was for this project – how well it was based in any kind of feasible science … but for all we know there might have been some potential in the idea. It may seem absurd from the get-go – but sometimes absurd ideas lead down productive paths. That’s all I’m trying to say. |
danithew, Like I said, it is a laudable path to take, thinking outside the box, but as Devyn said, at what point is it a waste of resources? |
Dan: whatever dude. you keep living in your dreamworld. I remember once when I tried to take a shortcut by cutting through Brookline to get to Storrow Drive, but found out (too late) that there was a Red Sox game going on. So a friend and I were sitting in my car, stuck in traffic in the Fenway park area, and I was in a left-hand turn lane. By the time that I got to the font of the line, the light had been red for at least 3 seconds, though the cars in front of me all went through it. I wish I could have gone, but cars at the opposite signal were already inching into the intersection. So I stopped. The guy behind me was in an 18 wheeler, and started leaning out of his window shouting things at me that I couldn’t make out from my vantage point inside my car with the window rolled up. I was feeling like doing something funny, so I rolled down my window, leaned outside and yelled back, “You want a piece of me?” as loud as I could over and over again. The guy kept yelling for a bit, and then finally shouted back, “Fag!” and sat back down behind the wheel of his truck. I took that to mean that I’d won. Devyn S: If we had spent that money on other things, who knows what the benefits would have been. I say the same thing to myself about farm subsidies and so many other government programs. That’s what makes me a conservative. |
“… as Devyn said, at what point is it a waste of resources?” It’s a good question and the answer would have a lot to do with a person’s priorities. One person’s “waste of time” may be another person’s “great idea.” It’s a common thing to criticize military spending and to think of all the good that could happen if we spend hundreds of billions of dollars on education (or insert another good cause) rather than on war. I can see why that line of reasoning would be appealing. |
DKL, Perhaps you don’t know me that well. I can go on and on about any subject I choose. I actually am surprised, based on previous debates you and I have had as to why you are even continuing debating me; I think you believe I’m beneath your logic and wisdom, so why do you keep “lowering yourself” to my level, DKL? I’m doing you the favor so you can keep your high and mighty position. But if you really want a piece of me, let’s go at it. I’m all game. |
danithew,
It is more than just appealing. It is a matter of who we are. Our prophets have warned us about relying on the arms of flesh for our protection. I think specifically of President Kimball’s “The False Gods We Worship” talk, wherein he chides us for our quickness at creating weapons of war, and glorifying the soldier, the warrior. If our priority is that we spend billions of dollars on warfare instead of finding better ways to educate the world, and to improve the lives of others, just what does that say about us? |
Dan: I think you believe I’m beneath your logic and wisdom, so why do you keep “lowering yourself†to my level, DKL? Because no matter how many times you disappoint me, I remain eternally optimistic. |
ah, the philosopher king trying to reach back into the cave to “save” me, eh? |
Dan, I think it will be easier to be “who we are” when Messiah comes. Until then, we have to worry about tyrants, kings, dictators, terrorists, etc. – which means to me that we cannot simply set aside the military or defense budgets for other purposes. Could the military spend money more wisely? Without a doubt. |
Star wars has cost billions of dollars for what?” Ice on the moon. BMDO paid for Clementine. |
danithew, In Matthew 24, we read:
I find that particular passage most interesting: “see that ye be not troubled.” Even through wars and rumors of wars and nations rising against nations. From my reading of scripture, the Lord is saying that the Saints should stay out of the conflicts of the world of men. Zion is to be a place of refuge from the violence and evils of the world. How can that be if we are ones who instigate warfare, and press for more ways to kill? We will be safe if we trust in the Lord. I’m not advocating dropping our weapons. Hardly. But we must trust more in the Lord for our protection than in the arms of flesh. That’s my point. Our current priorities are far from this. |
Dan, if Jesus said that, then he was almost certainly talking to people who thought that Jesus would establish a political Kingdom and overthrow the Romans in their own lifetimes. I seriously doubt that the particular of Jesus that you quote has any applicability to us. |
Why would “see that ye be not troubled” not have any applicability to us today? |
DKL – I would agree completely on the comment about farm subsidies as well as many other social programs – like giving welfare to graduate students. However, there are some programs worth spending money on such as reinvigorating urban blight, more scientific research, stem cells, etc. Danithew – so true one persons dream is anothers nightmare… |

Thanks Jack, |
herodotus (sorry to comment so late, I am)#5: I don’t think showing scenes of atmospheric events is considered ‘science’. You seem a bit ambiguous about emissions…’…probably will have a deleterious effect” suggests something rather vague, possible in the future… you say you’re a scientist; is this subject covered in your field (or expertise)? I HATE AMBIGUITY, especially about something as critical-crucial as this. the ‘reason’ – excuse: ‘Well, the last days are coming’… |
Guy |
Can we at least agree to call it “climate change” and not “global warming”? (Because calling it the latter just allows for a very large class of people to point to winter extremes, scratch themselves, and mutter sarcastically, “Ummm yeah, global warming!”) [I am not making any qualitative judgment about the science or solutions, either way.] |
DevynS: since I’m not a scientist or even familiar with the science involved, a) my opinion is only a product of slight media exposure (haven’t even read AG’s book)… I would hope that a body of scientists w/could make a group endorsement of one view on this and other critical-crucial matters to help ‘world opinion’. I’m not sure about the ration of (living)people to ‘all the grains of sand in the world’ , but that’s my mind on the value of opinions…. I live in Ohio; during our -x winters, I’m HOPING for some Global Warming! |
Good for Bush on that one. |
Ok I admit I did not read all comments soooo much,so I am really only commenting on the first few statements presented here and general, I get a strong feeling that the theme is too serious to not care about and that it is pretty arrogant to not care about this in our time. Fair enough many uncertainties are there, but in a vulnerable area like the artic (where I grew up)things are changing fast, and how can anybody not worry what rapid melting iceglacier does to the total environment. I found Al Gores film convincing and even if there is some political agenda as well, I think he deserved the Price he got. Also I think (so far) that the Jury from the more Artic area (Norway and so on)would be more likely to have looked into certain areas of his statements on environment and they have also access to research in these particular areas. I do not think a single person from the Artic would be arrogant about AGs concerns in the film. And I have a lot to learn here for sure, I think most people have. Being of the LDS faith myself I am sure we should all pull together to do a little bit more, and not sit by and just watch it all happen without at least trying and at least get some awareness. The Church leader has many times indicated that the members need to be informed and active citizens, without taking a political stand. For those who are well read in the literature of the church and scriptures, it is clear that a lifestyle more in line with those doctrines (and not just friends well meaning thoughts) |
People, |
So now that global warming climate models are in a shambles and the “consensus” on anthropomorphic global warming seems to be dissolving, do I get extra credit for pointing out (starting in comment #111) that the science behind it was demonstrably half-baked? My basic argument was that you cannot establish the predictive value of a theory or model merely by comparing it to data accumulated before the advent of the theory or model. In the course of arguing against multiple working scientists, I demonstrated that they did not understand the nature of argumentation, did not understand the purpose of theoretical models, that they did not understand the nature of causation and causal relations, and that a few of them were trying to pretend to be experts an areas where they hadn’t the least bit of training (viz., the law of diminishing returns — but global warming, too, by inference). (Perhaps I can be pardoned for being particularly proud of my contribution to this thread, because I offer so many decisive arguments across a vast and astoundingly broad range of topics — an intellectual tour de force to be sure.) Is anyone here who argued in favor of global warming prepared to admit that things are starting to look pretty good for the position that I staked out? |
Been drinking too much egg nog DKL? How about a link or two to explain what you are talking about? I am not aware of any “consensus” or shambles… |
I’ll get you some links in the morning. In the meantime, you should re-read the exchange. My favorite part of the exchange had to do with the core argument: 1. I argue that you cannot use currently accumulated data to establish the predictive validity of a model, and I use currency trading data as an example In sum: Nobody laid a finger on the core argument. Instead, attempts by working scientists on this thread to refute my argument demonstrated a decided inability to think critically on their part — an inability that is particularly worrisome among scientists holding views of substantial political import. And seriously: how is it possible that a “scientist” like dhasterok can actually believe something as stupid as the idea that it’s impossible for 0 divided by 0 to have an answer? |
DKL, sadly you place too much faith in the truth. The government-academic complex is beyond compromised at this point. |
I’m so sick of all this politicized silliness that I’m almost resigned to just wait for a couple of decades–and see what’s going on then. As for the present–I tend to side with the “heretics.” I really doubt we’re going to see any Gore-like catastrophes within the next fifty years. In fact, I wouldn’t be surprised if we have problems with cooling instead. |
DKL, I think you are right, but I think you oversimplify your argument. The universal empirical test of a scientific theory is “explanatory power”, which we might generalize as the “reduction in surprise” relative to some other theory, or no theory at all, when a series of actual experiments is performed. The problem with supposing that a rough linear correlation over two or three decades is good confirmation of a theory is that the reduction in surprise (measured in bits) provided by such a correlation is very low. On the other hand, a theory that provided a faithful a priori prediction of surface temperatures as a function of carbon dioxide levels over several complex up and down cycles, would indeed have provided a very significant reduction in surprise over the period concerned. Unfortunately, we have no such data. The period over which current theories have been forward tested is too short, and the correlation is too weak to avoid the significant possibility of being incidental. |
Mark D., The sad thing is–if there were an incidental correlation (in the short term) it would be touted as “proof” of the broader picture. I’m not blaming scientists per se. No doubt most are on the more conservative end of things when it comes to nailing down theories. It’s when science gets dragged into the political arena that “conclusions” are arrived at more rashly. |
Here’s a post by a Mormon scientist on the subject. |
Lights out » LDS Church, Utah’s capital city join worldwide event The Salt Lake Tribune Updated: 03/27/2009 12:07:08 AM MDT Many times the Las Vegas Strip and the Church of Jesus Christ of Latter-day Saints don’t see eye to eye, but they will this Saturday. During “Earth Hour,” Sin City and the iconographic temple of the Saints go dark for 60 minutes beginning at 8:30 p.m. local time as part of the worldwide effort to focus on climate change. The World Wildlife Fund, organizer of Earth Hour, has signed up 2,400 cities in 82 countries. That’s eight times as many participants as last year, when more than 36 million people took part. The lights-off hour is called a potent symbol of what can happen through collective action. “Climate Change is a growing international crisis no country can afford to overlook,” said Egypt’s First Lady Suzanne Mubarak. “Global warming negatively impacts the environment as well as the health and livelihoods of people worldwide. “Earth Hour heightens awareness and brings hope to the preservation of our shared planet’s precious environment today and for generations to come.” Salt Lake City will be participating by turning off the lights at the downtown City County Building. Marriott hotels worldwide will be a part, as will McDonald’s, the National Geographic Society, Wells Fargo and other businesses. The lights on the Salt Lake Temple will be turned off 8:30 – 9:30 p.m., said LDS Church spokesman Scott Trotter.

Yes. http://www.ksl.com/?nid=148&sid=6042363 Al Gore to meet with LDS Church leaders Gore came to Utah to introduce what would become his Academy Award-winning film “An Inconvenient Truth” at the Sundance Film Festival in 2006. Since then, the Nobel Prize winner often takes the opportunity to meet with civic, corporate and religious leaders around the country talking about the dangers of and solutions to climate change. The Church of Jesus Christ of Latter-day Saints issued a statement regarding the meeting late Thursday afternoon, saying: “Mr. Gore will have a brief courtesy visit with President Monson. He will also meet with other Church leaders afterwards. The meeting is at the request of the former vice president.” There will be a photo opportunity with Mr. Gore and Church leaders around 7 p.m. We’ll have that for you tonight on KSL 5 News at 10.

What causes global warming? Like glass in a greenhouse, these gases allow the sun’s heat through the atmosphere, but then trap much of it near the Earth’s surface. For billions of years they have played an important role in maintaining the proper temperatures for life to thrive. But since the Industrial Revolution, human activity has led to a dramatic increase in the amount of these heat-trapping gases. Carbon dioxide levels have risen from pre-Industrial levels of 280 parts per million to 379 parts per million. The amount of methane, another greenhouse gas, has more than doubled. The result has been a measurable warming trend called global climate change or, more specifically, global warming. Click here to enlarge Back to top ——————————————————————————– How do we know global warming is really happening? Temperatures have risen about 1.3 degrees F since the late 19th century. Greenhouse gas levels in the atmosphere have increased by 18% (nitrous oxide), 35% (carbon dioxide), and 148% (methane).

dhasterok, Since you are a more of expert about global warming what say you on the question below? What is your reponse to the link also? What is the relationship between solar variation and climate change? |
Brigham Young and The Environment http://maxwellinstitute.byu.edu/publications/books/?bookid=49&chapid=302 |
Lancaster, Something good to note from the Maxwell Institute bit, which applies to much of what you cite:
|
Read carefully the views of Brigham Young. Should we not give particular attention to sayings of the Brethren from the past and present? Every time I read a conference talk the Brethren digs deep to our history. “Prudent stewardship and wise use of resources are principles that Church leaders have emphasized throughout the history of the Church,†said Trotter. Brigham Young is just an example. The Maxwell Institute is refering to the author Hugh Nibley not a past Prophet. There is no doubt of a long tradition of a LDS environmental ethic. |
There is a spiritual, moral , and relgious connection between the environment and LDS thought. More quotes of Brigham Young taken from the article by Hugh Nibley as published by Maxwell Institutie. To find the sources please refer to post #365. Indeed it is immoral to pollute the soil , air and water intentionally. “You are here commencing anew,” he told the people. “The soil, the air, the water are all pure and healthy. Do not suffer them to become polluted with wickedness. Strive to preserve the elements from being contaminated by the filthy, wicked conduct and sayings of those who pervert the intelligence God has bestowed upon the human family.”1 For Brigham, moral and physical cleanliness and pollution are no more to be separated than mind and body: “Keep your valley pure, keep your towns as pure as you possibly can, keep your hearts pure, and labour what you can consistently, but not so as to injure yourselves. Be faithful in your religion. Be full of love and kindness towards each other.”2 Our work is “to beautify the whole face of the earth, until it shall become like the garden of Eden.”27 “The very object of our existence here is to handle the temporal elements of this world and subdue the earth, multiplying those organisms of plants and animals God has designed shall dwell upon it.”28 |
More commentary on LDS environmental theology |
Excellent blog on LDS relationship to the earth. |
Thanks Lancaster for the information. While I tend to agree with you, others may not but c’est la vie. |
Not to start a new argument but I am of the opinion that “manmade global warming” is primarily a political cause and not an environmental one. Post#358 by Jack is very revealing. No offense to anyone here but Al Gore is an opportunist politician. |
372 – Rick – are you saying global warming is manmade or that there is a political version of global warming? |
Do I believe that global warming exists? Yes. Do I think that man has any real significant impact on it? No. I believe it is used as a political tool for both pulling votes from one side or the other. I also believe that as humans have only a minute affect on the amount of CO2 in the air and because that amount is minute to begin with, it seems highly unlikely mankind can move the pendulum so far to either direction. I have no doubt that goverment, politicians, and their willing benefactors in the science industry will tell us just exactly what will give them as much control and power as they can possibly achieve. History has proven that many times. |
It actually takes very little effort to study climate history to learn that much greater fluctuations have occurred in the past than what happened in the 20th century. A little more study reveals that CO2 levels have little or no effect on global temperature. A little more study shows that the climate-change Chicken Littles have told quite a few lies. Global temperature change is more tied in to changes in solar radiation, not CO2. Water vapor (clouds) have many times more effect on global temperatures than does CO2, and man-made CO2 is only a tiny fraction of total CO2 in the atmosphere. The Chicken-Littles have also cooked the books. They altered the temperature measurement parameters over the years in order to make it look worse, by using an increasing percentage of urban temperature-taking locations that was greater than the increase in urban land areas in relation to the planet as a whole. They’ve also been caught in lies about volume of ice at the polar regions. Ice and snow are three dimensional, not two dimensional. But looking only at two-dimensional _area_, and not at the increase in _thickness_ of snow/ice layers at the South Pole, they make it look worse. Much of Antarctica is actually gaining in thickness of ice/snow over the land-mass. Ice shelfs surrounding parts of Antarctica have decreased in area, but ice shelfs in other parts that got bigger were not reported. They’ve been caught in the lie of saying that certain areas North of Canada were never ice-free before, when in fact, there’s a 50-year cycle of currents that melts some ice immediately North of Canada. So “never in my life-time” gets reported as “never before in history”. Another important fact is that the majority of the temperature increase of the 20th century occured prior to the post WWII increase of CO2 levels. There has been nazi-like propaganda by the climate Chicken-Littles. Tell a lie often enough and loud enough, and people start to believe it. Fer cryin out loud, CO2 is PLANT FOOD! Want less CO2 in the atmosphere? Plant more evergreen trees. |
Indeed it is immoral to pollute the soil , air and water intentionally. I agree 100%. However, the idea that carbon dioxide is pollution is quite a stretch. |
374. Rick M – thanks for the clarification. I would agree that it has been used as a political tool, although both sides seem to embrace it now as a reality. I must disagree with you when you say man has little impact on the CO2 in the atmosphere – from auto emissions, to burning rainforests, man has significant impact on the CO2 levels in the atmosphere which is why they have been increasing. So say otherwise is wrong. Whether you believe the increasing CO2 has an impact on the temperature is up to you, but in my mind there is enough evidence to suggest there is a problem with our increasing industrialization and that it would behoove us to cut back on polluting our environment. 375. Bookslinger – glad to know you are the expert and have all of the answers :) I don’t think anyone has all of the answers, but the “chicken littles” you refer to happen to be very intelligent scientists who are measuring this data. I think that the result in my mind is that there is some significant polluting going on by us humans. You say that CO2 levels rising does not matter but you are wrong. Too much CO2 will kill life just as too much O2 would kill you. I think that this issue is not as black and white as you paint it but very much grey which means that we should be more careful to not pollute and be careful to take care of the environment. Seems in line with the Gospel to me. |
One reason I believe it is a political control tool is all the talk about how we (in the US)can control it by our resource consumption an our actions such as more stringent emissions standards. Bear with me. This is tedious and boring and Bookslinger has summarized nicely without the tediousness. |
Rick M, Bookslinger, This has been a bitter issue for me for the last 2 years in school, where “Climate Change” is usually used as a device of fear to support policital agendas- indeed a political device. Your issues with CO2 are valid as well. However, CO2 is only one of the greenhouse gases. Humans produce a number of greenhouse gases that, with CO2, contribute to global warming- ozones, sulfuric and nitrogenic gases, etc. The impacts occur on a global level, but interestingly, mostly at the local level with urban heat islands. So the issue has a lot to do with rapid urbanization as a correlate and cause of not only more pollution, but more dense pollution. If the isue were CO2 alone, I don’t think it would hold water. But there are other pollutants that combine with CO2 to cause damage. Regardless, I think it is in our best interest to close as many loops in our lifestyles as possible. Zero emissions is responsible and good for society ecosysem-wise and health-wise. I think sustainability is a sound thing that should appeal to anyone, regardless of political bent. It doesn’t make a lot of sense to me to allow more CO2 or anything into the atmosphere than our planet has ability to convert. And I couldn’t say enough bad about Al Gore… |
For once I agree with nasamomdele. It almost doesn’t matter what you think of CO2. There are plenty of reasons to change energy policy. The geopolitical reasons alone should be enough to close the issue, not to mention the health and environmental reasons. |
CO2 issues are totally apart from pollution issues, though they are often produced together. But the CO2 produced by human activity is not a problem. The CO2 contributed to the atmosphere by human activity is comparable to a fart in a windstorm. Particulates, and things like sulfur, and real contaminants, industrial pollution, things where human activity puts the majority of those things in the atmosphere, and things that normally wouldn’t be in the atmosphere, THOSE are problems and should be reduced. Yes, let’s reduce the smog in Los Angeles, and the industrial-sourced haze in Denver, and the “Ohio Valley Crud” in Louisville Kentucky, etc. Those things actually make people sick. CO2 is NOT, I repeat, IS NOT a pollutant. But if you THINK it is, and want to actually believe it is, then go plant evergreen trees. And donate to charities that work to keep some green-space in parts of the world where they are clear-cutting trees. There are some problems in some areas where they are removing 100% of the bio-mass. But with some smart investment by eco-minded people, they could easily keep a good percentage of the bio-mass in a patch-work, where they are now otherwise clear-cutting. |
CO2 and pollutants are comparing apples and oranges. Should I add the example of Mount St. Helens spewing more of those pollutants into the air with that one eruption than all the automobiles ever built since 1900 combined? |
Bookslinger – it depends on your definition of a pollutant. But regardless, I think we agree that we should reduce our pollution to prevent destroying the world. |
http://www.umich.edu/~gs265/society/greenhouse.htm http://www.duke.edu/web/nicholas/bio217/tls14/intro.html http://en.wikipedia.org/wiki/Greenhouse_gas Read the last url above which states the concentration of green house gases in the atomophere. Verify various references . Wikepedia is only a review of literature # 376 “Let’s start with CO2. The Earth’s atmosphere has a certain percentage of CO2. A very small percent in fact. Of that very small percent, less than 1% of that small percentage is actually manmade.” This statement is correct however we are to discussing the concentration of green house gases that contributes to global warming which ranks 2nd when compared to all other gases. One has to understand your premis before one can follown your argument . Please let us all conduct due deligence before conducting analysis. |
B Tippetts, I rarely if ever use wikipedia. I did look at your Michigan link and there is one aspect that is missing from the pretty little picture. The fact that solar radiation is also reflected away from the Earth by our atmosphere. The diagram smakes it appear that ALL solar radiation makes it through and then is trapped within the atmospheric barrier. A simple example would be the lack of any significant atmosphere on the Earth’s Moon and the average surface temperature being about 107 degrees Celsius on the side exposed to the Sun and -153 C on the dark side. There will be no 20 foot rise in sea level due to Mr. Gore’s delusions. |
I think the biggest problem with the whole debate is the (seeming) disconnect between Climatology — the science itself — and the handling of data. Many climatologists will spell out how the whole thing works (or should work) but then the data doesn’t seem to match as well as it should — especially when it is predictive. I think some of the more well informed skeptics have punched some significant wholes in catastrophic predictions merely by reading the data differently or, dare I say, more thoroughly in some instances. |
Please read this article. My response is below http://www.ldsmag.com/ideas/090625global.html Gary Lawrence states “global warming and climate change – are convenient excuses to ignore God’s intended messages”. No. Global warming and how we are destroying the earth is a wake up call to take heed of God’s intended message to protect it, for if we do not the earth will not sustain us thus causing an apocalypse . Not protecting the earth is a global social sin and misinterpretation of prophetic warnings. As stated by John The Revelator: “The nations raged, but your [God ] wrath has come, and the time for judging the dead, for rewarding your servants, the prophets and saints and all who fear your name, both small and great, and for destroying those who destroy the earth. “(Revelation 11:18) How we treat the earth has eternal consequences. Take heed the warnings of an earlier LDS prophet. “This earth is the home he has prepared for us, and we are to prepare ourselves and our habitations for the celestial glory in store for the faithful. You are here commencing anew . . . . The soil, the air, the water are all pure and healthy. Do not suffer them to become polluted with wickedness. Strive to preserve the elements from being contaminated by the filthy, wicked conduct and sayings of those who pervert the intelligence God has bestowed upon the human family. Not one particle of all that comprises this vast creation of God is our own. Everything we have has been bestowed upon us for our action, to see what we would do with it—whether we would use it for eternal life and exaltation or for eternal death and degradation.” (Brigham Young) To say human kind may be the cause of increase of global warming are the follies human kind misconduct thus putting the earth in jeopardy. . Indeed because the way we treat the planet can have global disastrous consequences which may also help induce quickly the Second Coming. Perhaps our LDS leaders are trying to tell us some thing when they turned off the Salt Lake City temple lights in solidarity of global warming awareness. Note: All Brigham Young quotes above were taken from Hugh Nibley’s essay “Brigham Young on the Environment.” See http://maxwellinstitu .byu.edu/publications/books/?bookid=49&chapid=302 |
Tippetts, you’d do better to offer more logic and fewer blind appeals to authority. |
personally I am more worried about the planet getting hit by an asteroid than global warming taking us out. |
Tippetts, after reading the article at the link you supplied and then reading your reply, I’ve come to one conclusion – you didn’t understand what he was trying to convey. His main point appeared to be, we should look at the warnings of the Bible (earth quakes, massive storms and other disasters) and realize that they are happening many time’s because we are turning away from God. He went on to say that many times people will say, “It’s because of Global Warming that this disaster happened, not because God is sending a warning that we are wicked.” So we worry and discuss what can we do to fix the problem…easy, turn back to God. Why did the church turn off the lights – oh, they must have bought into global warming – the church does many things to put the church in a good light. If they ignored this gesture, they probably would have been held up in a (no pun intended) bad light. Truly, I don’t believe man is causing Global Warming – I do believe that the climate has warmed and may continue to warm or cool…I don’t know – unless you tell me that bad things are happening because we’ve turned away from God…then I would agree. |
When science tries to explain global or other earth calamities which maybe human induced , relgiionist simply pull out a straw with out any rational analysis and state such science is only a ruse to move us away from Jesus Christ message. However many signs of the times such as are indeed partially caused by social sins of humanity. Mistreating the planet and not replenishing it induces wars, famine, pestilence . LDS Church turning off the temple lights is an admonishment to humankind that we should righteous stewards over the earth. Take heed what our latter day Prophets are telling us |
Al Gore, what a douchebag. |
Water vapor is the overwhelming contributing atmospheric gas to the greenhouse effect. Carbon dioxide content of the atmosphere is a very small contributor and is not a significant factor in the greenhouse effect that keeps the atmosphere warm. All gases including CO2 that are put into the atmosphere by human activities are so miniscule that they do not warrant being mentioned when considering what gases and other factors contribute to the greenhouse effect. The Sun is the primary factor in determining how warm or cold the climate of the planet is now and will be. These are irrefutable facts that no qualified scientist can deny or will even try to deny. The people behind the movement to scare ignorant inhabitants of the planet into giving away their agency and ceding control to them are the same people that have been using fear to control people since mass communication has enabled them to do so. I am a qualified scientist. I have credentials that will impress most people. If I want to become a millionaire all I need to do is pretend to do a bunch of legitimate research and publish finding that support the people who have evil designs on controlling others for their own gain. Today the trend is to scare people about the weather (though it is becoming more difficult as the facts become more difficult to conceal and distort). But I could just as easily start worrying you about diet soda. I could tell show you –with real research data– that diet soda is causing an epidemic of pancreatic cancer and other serious illnesses and cite Steve Jobs. I actually suspect a correlation exists. But I am not going to say such a thing through a published study because it would be irresponsible to do so until such a correlation is definitively proven. And no, just because their might be a correlation there is no justification for taking preventative steps in a misguided attempt to misapply to adage, “better safe than sorry”. Life is nothing but an exercise in risk management no matter what you do. Life is not safe and never will be. Life for everyone will eventually result in death. The cause of all deaths is irrefutably proven to be the result of people chosing to do things that are unsafe. Unsafe being defined as anything that leads to death. Well, life leads to death. Therefore life is unsafe. I don’t drink diet sodas because I think the artificial sweeteners are an unnecessary risk. But for some people, the risk is worth it for whatever reason. And who knows how many people live longer lives because they worry less? Clearly people are not dropping dead after they drink a diet soda, or ten or thousand or ten thousand — at least not in easily verified and identified numbers. So me not going around sounding the alarm bells prematurely is exactly the right thing to do. If every person on the planet drove a gas guzzling car all day long burning very smoky and polluting fuel the entirety of the human race could not raise or lower the temperature of the planet a single degree in 100 years. Sorry, that’s the truth. On the contrary, one volcano at the bottom of the ocean can spew enough CO2 in a year to affect the planets temperature. Of course the reason the 13,000 or so active oceanic volcanoes do not radically alter the climate one way or the other even though they belch more CO2 in a year than all of humanity has emitted in its entire history is that plants LOVE the stuff and gobble it up. How do you think we got such juicy concentrations of oil, coal and gas in the layers of the earth’s crust? Because long ago when time was passing way more quickly (because magnetic fields, solar and cosmic radiation were fantastically higher and very different than they are today. What? You did not know that? I’m surprised! You mean no one has told you that we have irrefutable evidence that the atmosphere had 100 times the CO2 and twice the oxygen it does today when the dinosaurs were stomping around? Plants and animals were not only gigantic, they also grew WAY more quickly and died way more quickly. They got doused with sunlight, water, oxygen and CO2. They matured quickly, bred quickly, grew quickly, lived quickly and died quickly. It’s almost as if a God had designed a time period that would load up the crust of the earth with hugely useful organic stuff like oil, coal and gas. (Yeah, oil is as natural as it gets! It’s more of Mother Earth than a handful of earth.) Carbon dating is faulty because radiation levels were off the charts. How do we know know all this? Very simple deduction that you are neve taught to make. For instance, what conditions would explain plants and animals getting covered by sediment before they were eaten or ecomposed? I mean has it ever occurred to you to ask yourself “Why do plants and animals either get eaten by something else or decompose so thoroughly that they will leave no fossils and they go back into the soil as organic molecules instead of congealing in gooey oil slicks?” Oh, I could go on introducing important and relevent facts about the earth, it’s climate and how the moon has more to do with the seasons and why you should not be afraid of radioactivity than GM, Toyota and Energy Solutions all put together. But what’s the point? You have been dutifully playing the role of the frightened serf. And the reason for this thread was not to wonder why the Church does not attempt to educate its members directly about scientific facts; choosing rather to do it indirectly through admonition and support of institutions of higher education. No, this thread in this forum is about asking why the Church does not join the anti-human race people who want to subjugate and eliminate humanity from the planet because “animals are people too” and although termites passing gas is a significant contributor to the amount of CO2 of such a larger magnitude than all of humanity’s contribution that anyone who was actually and truthfully concerned about (the non-issue of) reducing CO2 would only be concerned about how to give Gas-Ex to terminites, we have to have a silly discussion about why the Church isn’t telling its members to help those who would enslave them by jumping on the fear-mongering Express on a ride to the oblivion of ignorance. Whatever. Hope I did not detract from your thoughts on how you are going to press the Church into installing waterless urinals in every Church building. Now there’s a good use of tithing! Heaven knows I want to smell that stink of concentrated urine outside every Church building like you do when you walk out of the IKEA in Draper, Utah. If you are ever wanting to experience the negative side of the idiocy of “saving” water stand outside IKEA in Draper near the loading area and suck in a nice breath of fumes coming out of the manhole covers from the concentrated uric acid that flows below. “Saving” water can only be done by BANNING the production of fuel cells which break down water. I do not advocate banning anything but if I did it would be stupid things like insufficient-flow toilets (which don’t “save” water even if such an idiocy were possible), waterless urinals, destroying water by converting it into hydrogen and oxygen and turning corn that could feed animals and people into expensive, dirty fuel to burn in place of inexpensive, abundant clean gasoline that won’t cause food shortages. That’s right, you cannot “save” water because it does not go away when you “use” it. Unless you do something stupid like use electricity to rip appart H2O into its elemental gases which is what fuel cells do. Sorry, I’m keeping you from pushing the Brethren to waste more of my tithing. Go ahead, get back to your “It’s immoral not to save Mother Earth” lecture to God’s annointed. Because of course, they need you to tell them how to save their fragile planet. Shoot. They’re just in direct communication with the creator of the planet. What do they know!? |
A lot of Mormons, like Americans in general, just have not yet realized how bad climate change is predicted to be, especially when/if the expected feedback loops start to kick in. There is a lot of mis-information out there (water vapor, natural cycles, etc.), which many people say is actively encouraged by the likes of Exxon. For reliable info, check out what real scientists say at realclimate.org. Several months ago I decided to “go to school” on this issue. What I found is that 97% of climate scientists believe humans are causing serious climate change. I looked for credible opposing views, for balance; but what I found on the “doubter” side was mostly a few scientists who lack credibility due to financial ties to oil companies. The book that best explained the seriousness of the problem to me was Six Degrees, published by National Geographic. It is a lengthy but very readable summary of what the scientific literature has been saying. Scientists are still learning, but what they have found so far indicates it’s going to get very bad. The prophecies in the scriptures about war, droughts, plagues, famines, tempests, and seas heaving beyond their bounds are pretty much the same as what is now expected from climate change. Ironically, it appears we have literally brought the calamities of the last days upon ourselves. |
hello!,I like your writing very so much! proportion we be in contact extra about your post on AOL? I require an expert on this area to resolve my problem. May be that is you! Having a look forward to see you. |
