Why Global Warming Deniers are a Liability
Jonathan Kay has written a piece which explains why Global Warming deniers do harm to the conservative movement:
Have you heard about the “growing number” of eminent scientists who reject the theory that man-made greenhouse gases are increasing the earth’s temperature? It’s one of those factoids that, for years, has been casually dropped into the opening paragraphs of conservative manifestos against climate-change treaties and legislation. A web site maintained by the office of a U.S. Senator has for years instructed us that a “growing number of scientists” are becoming climate-change “skeptics.” This year, the chairman of the Australian Broadcasting Corporation gave a speech praising the “growing number of distinguished scientists [who are] challenging the conventional wisdom with alternative theories and peer reviewed research.” In this newspaper, a columnist recently described the “growing skepticism about the theory of man-made climate change.” Surely, the conventional wisdom is on the cusp of being overthrown entirely: Another colleague proclaimed that we are approaching “the church of global warming’s Galileo moment.”
Fine-sounding rhetoric — but all of it nonsense. In a new article published in the Proceedings of the Natural Academy of Sciences, a group of scholars from Stanford University, the University of Toronto and elsewhere provide a statistical breakdown of the opinions of the world’s most prominent climate experts. Their conclusion: The group that is skeptical of the evidence of man-made global warming “comprises only 2% of the top 50 climate researchers as ranked by expertise (number of climate publications), 3% of researchers in the top 100, and 2.5% of the top 200, excluding researchers present in both groups … This result closely agrees with expert surveys, indicating that [about] 97% of self-identified actively publishing climate scientists agree with the tenets of [man-made global warming].”
How has this tiny 2-3% sliver of fringe opinion been reinvented as a perpetually “growing” share of the scientific community? Most climate-change deniers (or “skeptics,” or whatever term one prefers) tend to inhabit militantly right-wing blogs and other Internet echo chambers populated entirely by other deniers. In these electronic enclaves — where a smattering of citations to legitimate scientific authorities typically is larded up with heaps of add-on commentary from pundits, economists and YouTube jesters who haven’t any formal training in climate sciences — it becomes easy to swallow the fallacy that the whole world, including the respected scientific community, is jumping on the denier bandwagon.
This is a phenomenon that should worry not only environmentalists, but also conservatives themselves: The conviction that global warming is some sort of giant intellectual fraud now has become a leading bullet point within mainstream North American conservatism; and so has come to bathe the whole movement in its increasingly crankish, conspiratorial glow.
Conservatives often pride themselves on their hard-headed approach to public-policy — in contradistinction to liberals, who generally are typecast as fuzzy-headed utopians. Yet when it comes to climate change, many conservatives I know will assign credibility to any stray piece of junk science that lands in their inbox … so long as it happens to support their own desired conclusion. (One conservative columnist I know formed her skeptical views on global warming based on testimonials she heard from novelist Michael Crichton.) The result is farcical: Impressionable conservatives who lack the numeracy skills to perform long division or balance their checkbooks feel entitled to spew elaborate proofs purporting to demonstrate how global warming is in fact caused by sunspots or flatulent farm animals. Or they will go on at great length about how “climategate” has exposed the whole global-warming phenomenon as a charade — despite the fact that a subsequent investigation exculpated research investigators from the charge that they had suppressed temperature data. (In fact, “climategate” was overhyped from the beginning, since the scientific community always had other historical temperature data sets at its disposal — that maintained by the Goddard Institute for Space Studies, most notably — entirely independent of the Climactic Research Unit at the University of East Anglia, where the controversy emerged.)
Let me be clear: Climate-change denialism does not comprise a conspiracy theory, per se: Those aforementioned 2% of eminent scientists prove as much. I personally know several denialists whom I generally consider to be intelligent and thoughtful. But the most militant denialists do share with conspiracists many of the same habits of mind. Oxford University scholar Steve Clarke and Brian Keeley of Washington University have defined conspiracy theories as those worldviews that trace important events to a secretive, nefarious cabal; and whose proponents consistently respond to contrary facts not by modifying their hypothesis, but instead by insisting on the existence of ever-wider circles of high-level conspirators controlling most or all parts of society. This describes, more or less, how radicalized warming deniers treat the subject of their obsession: They see global warming as a Luddite plot hatched by Greenpeace, the Sierra Club and Al Gore to destroy industrial society. And whenever some politician, celebrity or international organization expresses support for the all-but-unanimous view of the world’s scientific community, they inevitably will respond with a variation of “Ah, so they’ve gotten to them, too.”
