Bloggers and commentators have been talking a lot lately about a recent study, by Dan Kahan and colleagues in Nature Climate Change, capturing what I call the “smart idiot” effect: Conservatives who are more educated, or have a higher degree of scientific literacy, are more strongly in denial (or less worried) about global warming.
In this post, I want to underscore the robustness of this finding, by showing that it has also turned up in a study just out in the journal Polar Geography.
The paper (citation below; abstract here; author’s draft here) is by Lawrence Hamilton and his colleagues at the University of New Hampshire. In it, the researchers examine a wealth of survey data about people’s knowledge of (and concern about) global warming in the polar regions—data collected by the General Social Survey in 2006 and 2010. Then, they cross-reference these results with measurements of general scientific literacy and political ideology…and, well, that’s when the smart idiots show up to be counted. As we’ll see.
First, though, some background.
Polar warming is, as Laurel Whitney recently explained here, an extremely big deal. This isn’t just about what happens to the polar bears. The growing potential for exploitation of oil and gas in the Arctic, made accessible by ongoing sea ice and permafrost melting, adds a new variable to the global energy economy and also further amps up our potential carbon dioxide contributions to the atmosphere.
Perhaps even more important, however, is the risk–if global warming advances far enough—of destabilizing the Greenland and West Antarctic ice sheets.
