Climate Change and the Political Impasse

leave a comment »

Bradford Plumer over at The New Republic has an excellent review up on a leading climate scientist’s latest book. Things are looking mighty grim:

I’m not trying to start a nerdy parlor game, but if we were to list the most important climate scientists of the past fifty years, James Hansen would have to be in the mix. Three decades ago, he helped create one of the world’s first climate models to predict how the Earth would heat up in response to rising greenhouse gases. (Many of his early forecasts held up well.) He stepped into the spotlight again in 1988, issuing one of the first climate warnings to Congress. And, in the 2000s, when Bush appointees tried to downplay the severity of global warming, Hansen was the one blowing the whistle. The director of NASA’s Goddard Institute for Space Studies is hardly infallible, but as would-be Cassandras go, his record has proven awfully solid.

Like many global-warming skeptics, Hansen has sharp disagreements with the mainstream scientific consensus on climate change. Unlike the deniers, however, he believes that the consensus view actually downplays the problem. The computer models used to project future warming, for example, seem to be too conservative: they failed to predict, among other things, the rapid collapse of summertime Arctic sea ice since 2007.
