Climate Change and the Integrity of Science

blau tips news of an open letter from 255 members of the US National Academy of Sciences, including 11 Nobel laureates, decrying the "recent escalation of political assaults on scientists in general and on climate scientists in particular." The letter lays out the basics of the scientific method, and explains how certainly highly-regarded theories — such as the big bang, evolution, and Earth's origin — are commonly accepted due to the strength of the evidence supporting them, though "fame still awaits anyone who could show these theories to be wrong." It goes on to "call for an end to McCarthy-like threats of criminal prosecution against our colleagues based on innuendo and guilt by association, the harassment of scientists by politicians seeking distractions to avoid taking action, and the outright lies being spread about them." According to the Guardian, the letter "originated with a number of NAS members who were frustrated at the misinformation being spread by climate deniers and the assaults on scientists by some policy-makers who hope to delay or avoid making policy decisions and are hiding behind the recent controversy around emails and minor errors in the IPCC."

      "and thus nobody's mind is ever changed."

      Fortunately that is not true over the long run, having argued the case for AGW on slashdot for the last decade I can say that the slashdot consensus on AGW has done a complete 180 degree turn around in that time. Ten years ago I was definitely in the minority and was constantly modded down for debunking basic stuff such as the "volcanos release more CO2 than mankind" myth. Sure there's still a minority who for political or religious reasons will never accept that mankind can warm the globe but the rest of us (including me) are now much better informed for having had the amature scientific debate.

      The public argument about the science of AGW is very similar to the public argument over smoking causing cancer. The strength of the FF lobby and their pet politicians is orders of magnitude greater than the strength of the tabacoo lobby in it's hayday. Scientists have not failed to communicate the science of AGW but they have not yet been successfull in battling the anti-science forces who know full well they are engaging in propoganda and witch hunts in an effort to keep the public in confused darkness. However you are right, it does not reflect well on society that there is still a vast army of usefull idiots who accept and parrot the anti-science position without question.

      But all is not lost, unlike propoganda and politics, science is objective and always wins in the long run. Evolution, plate techtonics, and AGW, are "scientific facts" where people can see the evidence for themselves. Gun laws, abortion rights, and what to do about AGW, are subjective and those are the wedge arguments that, fueled by the blind faith of politics and religion, will rage forever.

      The problem with "AGW" is that it is bad science and mostly public relations, not necessarily actual science. I can name numerous sorts of problems with those who are pro-AGW just as those who are blatant deniers are equally out to lunch.

      A great part of the problem is that head smacking obvious issues like what caused the medieval global warming (hint, it had almost nothing to do with human impact on the environment) and the subsequent cold period that sort of peaked some time around the period of the American Revolution in the late 18th Century are certainly not satisfactorily explained with the current climatological models, and how anybody can measure the temperature of the whole of the Earth down to a fraction of a degree is something that I think is equally bogus.

      I'm not one to suggest that we need to completely ignore the effects of human civilization upon the global climate or even on a regional basis, but some balance does need to get back into the debate.

      Where the real problem comes in is not just the deniers who want to pop off a bunch of oil wells similar to what Saddam Hussein did in Kuwait at the end of the Gulf War and deliberately try to pollute the Earth and cause as much CO2 production as possible to prove that the AGW hypothesis is incorrect, but those who are of the opposite extreme and essentially wish to kill off the whole of human civilization and go even so far as advocating mass genocide as obviously mankind is a virus that needs to be exterminated.

      It is precisely the politics that has invaded science, as evidenced by this letter too, that is causing many of the problems. Those sitting on committees who are funding this kind of science are seemingly systematically killing off even modest questioning of basic concepts, and worse still is the suggestion that one and only one form of activity is solely responsible for any warming that the Earth may have had over the past couple of decades.

      These who would be honest scientists ought to decry and distance themselves from activists who do really bizarre things like claiming extreme blizzards and heat waves are "evidence" of global warming, as are floods and droughts. Heck, any time there is any sort of weather of any kind and there is some story that says "Oh.... that was caused by global warming". Even ordinary temperate and fair weather is attributed to global warming.... thus making a farce of the whole notion in the first place.

      Can reasonable steps be done to reduce pollution in the environment in all its varied forms, and ought we be reasonable stewards over those things we are responsible for? Absolutely! At the same time, massive economic overhaul that causes mayham to almost everything we hold dear and turns folks like Al Gore into billionaires is not necessarily something I wish to advocate either, and certainly would be willing to call those who support crazy ideas like carbon tax credits without following the money and realizing what harm such a policy and concept causes is also just as silly.

      I, for one, am very concerned about carbon sequestration and the potential long-term pollution problems that sort of technical solution might cause, and even go so far as to argue that some of the methods of sequestration might end up causing more problems than simply letting it pipe out into the atmosphere. It is one thing to run the exhaust of a coal plant through a greenhouse to promote biomass production. It is another to shove the CO2 into the ground and pretend that it has no long-term impact if that is done for a century or two. I really worry about CO2 dumping into oceans and what sorts of long-term impacts that may have on the aquatic ecosystems.... yet those are schemes that are going to be given a carbon tax credit as it won't be going into the air.

For one AGW questions the literal truth of the Bible, because if AGW is true, then maybe God didn't really give the world to Christians to do with as they wish. The other big reason is that anti-evolutionists have a tendency to be anti-science, thus it is natural for them to take up any side which questions the credibility of scientists and scientific consensus.

If the medieval warm period was indeed global, it would argue that there is some additional mechanism that could add to or amplify the modern CO2 induced warming so as to cause global temperatures to shoot up even higher than projected.

The positive trend is quite close to the significance level. Achieving statistical significance in scientific terms is much more likely for longer periods, and much less likely for shorter periods.

      The problem that the parent post was highlighting is that in the tropics warm mosit air rises, as it does so the moisture falls out. However the air is now moving in a convection current that dumps huge amounts of dry air onto the subtropics (thus creating the current deserts in those areas). As the temprature increases the tropical convection currents become stronger and dump more dry air thus extending the reach of the desert zone further toward the poles. If this was to occur over geologic time scales, (as it has done in the distant past), our agriculture could easily adapt. However since it's expected to happen over human time scales, (wich has not been seen in the geologic record), all bets on the required rapid adaptation of agriculture are at best wishfull thinking.

      Like any other Aussie will tell you from first hand experience, modern agriculture is ill equiped to adapt to the sudden onset of a "permenant drought".

Even though I have a background in physics, I still don't have the math expertise to prove it. Yet I "believe" in it. Why? Because all the scientists claim that it's true. They say they've proved it and over the last 100 years, no scientist has challenged it. So I take their word for it. I have to. I accept the general theory of relativity even though I haven't personally proved it for myself. The same holds true for the overwhelming majority of fields in science, maths, geology etc etc.

      So can you say I'm blindly accepting the general theory of relativity? If by "blindly" you mean have it proved it for myself? Then yes. I'm blindly accepting it. But if you mean do I have reasons to believe it's true, then no it's not blind acceptance. I have very good reasons to "believe" it's true. Those reasons are that scientists believe in it. I can do no better and I challenge you to find another way (Hint: You can't go around studying for years to be able to prove something for every single field. I'll need a couple of thousand years for that).

      The same is even more true with an interdisciplinary science like climate change. It's very easy for amateurs like me to pick up some jargon here and there and using it to prove either side of a debate. But unless we're pros, we don't know the half of it. Every theory has ifs, buts, and exceptions. And since there's no way in hell I'm ever going to reach a stage where I can prove or disprove it for myself, I'll have to take the second best option and listen to those who are in a position to do it. And when the overwhelming majority of such people say that human caused climate change is real, I believe them - savvy? Just like I believe those scientists who say that the general theory of relativity is true.

      The only thing that's different about climate change is that scientist's positions can inconvenience vested interests. The government, big businesses and others who suddenly find they may have to change the way they live. So this has suddenly come up. Take all that out, and we would never have had this "denialist" charade.

It was a paper that should not have been published without major revisions. Among the criticisms of the paper they used precipitation proxies where they should have used temperature proxies and they took regional temperature changes as global changes. Half of the editorial staff resigned when the publisher wouldn't allow the chief editor to print a rebuttal of the paper. Even the publisher eventually admitted it should not have been published without revision. Like the editorial staff Phil Jones questioned why anyone would want to have their name associated with a journal that would publish such junk. Maybe that's why the journal went downhill.

      The majority of sources cited in AR4 were peer reviewed (12900/18500 according to one {skeptic} source). The IPCC AR4 report has 3 sections.

      Working Group I is about the physical science basis of climate change. I believe you'll find that nearly everything cited in the WG1 section is peer reviewed and anything that wasn't probably could have been.

      WG II is about the impacts and our vulnerability to climate change. There are more non-peer reviewed references in this section but I'd be surprised if the peer reviewed cites didn't outnumber them still.

      WG III is about mitigation, what we can do about it. By its very nature it has some political aspects to it and cited many government, NGO, and business sources as well as peer reviewed papers. This is where you will find most of the non-peer reviewed cites in the AR4 report.

These models depend on many variables, some of which are measured, some of which are estimated, and some of which are guessed. In addition the whole algorithmic process by which the "model" works is at best an approximation. Certain methods of modeling future climate result in lots of warming, some less. Right now there are large margins of error and much disagreement about exactly how "much" climate change we will experience.

      Now, it certainly seems plausible that there are models out there with variables and assumptions that result in no warming, or a cooling. What is the likelihood these would get published based purely on their results? Not good. Well then what is it about a model that makes it better than others? It's ability to "predict future changes" when plugged in with past data. However, as we go back in time we quickly start losing variables in quantity and precision. 100 years of good solid data (if it's even that much) is not much when it comes to modeling how the Earth's climate changes over it's vast history.

      The question is wrong, because as is it has no answer. The earth has no optimum temperature (unless you count the one that allows for rock to stabilize and not become an ionized plasma). What you want to know is what the optimum temperature range is for human habitation. As you can see by the current population distribution, it is quite wide, which could lead to the assumption that the optimum temperature range for human habitation is just as wide. That's incorrect. If you drop an Inuit into the Brazilian jungle, a Massai into the Midwest, or a Midwestern farmer into the Alps, they will die very quickly. See for example the pilgrims who first arrived in North America: they nearly died from starvation, even though the temperatures weren't that much different from what they were used to.

      As a result, the answer to that question is: exactly the one that you have right now around you. Civilizations have adapted to work in their current environment. Change that only a bit, and the impact on the people can be devastating.

      When has it been at that temperature in the past?

      See above for why this question doesn't give you a useful answer.

      Has it ever been outside that temperature in the past?

      Most decidedly. However, you don't want to go through the change again.

      How, specifically, do we know this?

      Historical records of both temperatures (inferred and directly recorded), and of historical records that chronicle the result of dramatic temperature changes.

      In particular, how does one define the temperature of the Earth, and how does then measure that?

      It's a good question. In general, it is understood to be the yearly average of multiple points across the globe, preferably along all latitudes and longitudes. But yes, temperature measurements are difficult, and it requires a lot of work to make sure that datasets from one source can be used for comparison with other data sets.

    So scientists who challenge the prevailing politically-correct liberal thesis are "climate deniers" - this is the basic problem. Even the term is ridiculous. Compare it to "holocaust denier". The holocaust was undeniably real - because there are still some living eye witnesses, photographs, original videos, documents etc. that clearly prove that it happened. What does it mean to be a "climate denier"? No one denies there is "climate". For too long people who challenged the "science" behind global warming were shouted down and ridiculed by their "peers". Now for a little bit, the shoe is on the other foot, and they don't like it a bit. BTW - CFL bulbs are a perfect example of why this type of "science" really has to be tried before accepted, and not pitch a fit if it is challenged - http://www.energystar.gov/ia/products/lighting/cfls/downloads/CFL_Cleanup_and_Disposal.pdf Just think about that - what about places where there is no window, where the only ventilation is forced air. Give me an incandescent bulb anyday. If it breaks, worst you worry about is a cut. When it burns out, you can safely toss it w/out worry about what its components will do to the environment or your local groundwater. Not to mention that the CFLs do not last anywhere as long as promised if you don't follow their optimal usage pattern (leave on for at least 15 mins, etc.) Certainly there are places where they are appropriate, but "environmentalists" pushing them down everyone's throat, and corporate greed (Walmart) jumping on the green bandwagon and being dishonest with people - you wonder why people with a brain are skeptical?

    I'm a proud skeptic, that is, somebody who wants to see evidence of extraordinary claims.

    George Monbiot has pointed out that "skeptic" is not an appropriate word for somebody who goes far out of their way to ignore evidence presented to them and seizes upon the thinnest contrary statements. That was his defense of the word "denier" and it started me using the word again. I remained skeptical until about five years ago, when the evidence started to look very convincing. Then the 2007 IPCC report won me over.

    What we're seeing the last few months is, to me, a fascinating study of how resistant people are to news they don't want to believe. The climate science has been slowly building up for decades, one peer-reviewed article after another, one dataset after another, the same story emerging from multiple angles. The scientific disputes dwindled away until we now have 97% of climate scientists surveyed last year on board with the same basic conclusions. Some thousands of scientists represented by the IPCC summary.

    Yes, Michael Crichton was correct that science isn't subject to voting and one guy can be right and a thousand wrong. But public policy makers should go with the preponderance of evidence, just like a court; leaning to the views of a small minority is not sound policy-making. If 97% of 1000 nuclear scientists thought a nuclear plant would blow up, would you build it?

    Then along comes "climategate" and everybody is actually told that they are being read a few sentences cherry-picked from thousands of E-mails, stripped of context. Hundreds of voices protest that the word "trick" is widely used for legitimate data manipulations.

    Nonetheless, not only do the denier voices, many of them from organizations shown to be funded by Exxon, immediately proclaim this to outweigh decades of work by a couple of battalions of PhDs, the general public starts polling sharp drops in agreement with climate-change theory that had slowly won them over.

    Conclusion: when people don't want to believe something because of its terrible costs, you have to convince them with a weight of evidence on the order of magnitude of 1000:1.
