Scientists Study How Non-Scientists Deny Climate Change (theguardian.com)

A new research paper suggest climate change opponents are "simulating coherence by conspiracism". Slashdot reader Layzej says the paper "examines this behavior at the aggregate level, but gives many examples where contradictory ideas are held by the same individual, and sometimes are presented within a single publication." From the paper: Claims that the globe "is cooling" can coexist with claims that the "observed warming is natural" and that "the human influence does not matter because warming is good for us". Coherence between these mutually contradictory opinions can only be achieved at a highly abstract level, namely that "something must be wrong" with the scientific evidence in order to justify a political position against climate change mitigation...

In a nutshell, the opposition to greenhouse gas emission cuts is the unifying and coherent position underlying all manifestations of climate science denial... Climate science denial is therefore perhaps best understood as a rational activity that replaces a coherent body of science with an incoherent and conspiracist body of pseudo-science for political reasons and with considerable political coherence and effectiveness.

"I think that people who deny basic science will continue to do so, no matter how contradictory their arguments may be," says one of the paper's authors, who suggests that the media should be wary of self-contradicting positions.

      Whilie the tactics of the pseudo-skeptics certainly have borrowed heavily from the Creationists (and the tobacco company-funded pseudoscientists), the intent isn't really to tap into belief that AGW is some sort of religious heresy. Rather, it taps into two streams; the tendencies of certain groups, particularly in conservative circles, to adopt a sort of kneejerk contrarianism to anything that requires a significant shift in the way society thinks, and in part of pure selfishness (i.e. I don't want to have to pay more for gas).

      Note that not just conservatives are guilty of contrarianism. You see similar views among antivaxxers, who are often liberal or left-leaning.

      For the pseudo-skeptics, having identified the audience they need to convince, it's simply a matter of tapping into the contrarianism via the classic path; associating the science with a "Liberal agenda". It probably hasn't helped that some of the chief advocates of AGW on the public stage have been liberals like Al Gore. This gives the pseudo-skeptics the target they need. When you couple that with a general Libertarian-style of anti-regulation, in which any attempt to price carbon will immediately lead to cries of government interference, well, you have a perfect mix; AGW is a Liberal lie whose sole purpose is to increase the power of the State. Finally throw in the pseudo-science itself; find a few like-minded scientists in related fields, get them to write articles in friendly papers, go on speaking tours and the like, and when they are inevitably critiqued, declare those critiques as attacks by the evil liberal scientific cabal.

      Again, this was all worked out a very long time ago when the Creationists began their own attacks on science. Tap into inherent contrariarnism in certain groups, attach nefarious motives (those evolutionists are trying to get rid of God), and throw in a few friendly scientists (Michael Behe, for instance, the intellectual forebearer of Frank Spencer), concoct some scientific sounding word salads, and voila, you have your Creationist attack on science.

      The AGW pseudo-skeptic community is also progressing towards the Creationists final tactic; accepting just enough of the science not to look utterly absurd. For Creationists, this was the creation of Intelligent Design, for AGW pseudo-skeptics it involves memes like "climate is always changing", or the newer "well yes, it is warming up, maybe we have something to do with it, maybe we don't, but we shouldn't do anything about it and instead should deal with the effects:.

      Creationism was probably the first really sophisticated propaganda war on science, but it has inspired several later pseudo-scientific propaganda wars. Creationism's intentions were more to protect Christianity from the perceived threat that if science could provide answers to the life we see today, it was going to chip away at the edifice of Theism until Atheism reigned supreme. I'd also argue that for at least some branches of Protestant Evangelism, there was the more real threat that the vast amount of social control those churches wielded being undermined if they were forced to accept that vast swathes of the Bible became understood as being metaphorical, and not literal.

      The story is a bit different for the tobacco, sugar, and fossil fuel industries. For them, a general acceptance of science has material costs. People reducing sugar consumption would lead to significant drops in profits. Of course, we know just how much damage the defeat of the tobacco companies has cost their investors. As for the fossil fuel industry, well it's the biggest beast of all. The entire global economy, and some of the greatest accretions of wealth ever known to humanity, are tied up in the continued exploration, extraction and use of hydrocarbons.

      That's not entirely true... the religious issue is that mankind is not supposed to have the power to destroy something that God told us to use as we please.

        So God created man in his image,
              in the image of God he created them;
              male and female he created them.

      God blessed them, and God said to them, “Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth.” God said, “See, I have given you every plant yielding seed that is upon the face of all the earth, and every tree with seed in its fruit; you shall have them for food. And to every beast of the earth, and to every bird of the air, and to everything that creeps on the earth, everything that has the breath of life, I have given every green plant for food.” And it was so." - Genesis 1:26-30.

      So, if we do as we were told, and in the process destroy the Earth, then that means we're powerful enough to undo what God created in a way that he did not expect, or something along those lines.

  28. Hiding the decline by BCGlorfindel · · Score: 3, Informative

    XKCD produced this graph http://xkcd.com/1732/ to shows how temperature has changed over the last 22,000 years

    xkcd is great, but the data he referenced follows the infamous "hide the decline" trick. The 'trick' is nothing more than using the instrumental temperature record to fill in gaps or quality in data. For the proxy records cited going back 20k years, the accuracy and precision over the last 100 is poor and the authors themselves state as much. Thus, to complete the data set through to today the instrumental record is included from 1900 onwards.

    Nothing really wrong with that. The only caveat is in how you interpret the graph. If you look at the graph and observe that there is an unprecedented trend set off at 1900, the beginning of the industrial era you have to be careful. The unprecedented trend ALSO coincides with a change in methodology and data source in the graph. Ruling out how sensitive the proxy data is to short term spikes like today is vitally important to interpreting that part of the graph well, and we're still working that.
