Asked by reporters yesterday if he accepts the scientific consensus that greenhouse gas emissions contribute to global warming, John Boehner demurred on the curious but increasingly familiar grounds that he is not a scientist. “Listen, I’m not qualified to debate the science over climate change,” the House Speaker said. Boehner immediately turned the question to the killing of jobs that would result from any proposal to reduce greenhouse gas emissions, which he asserts with unwavering certainty. (On this question, Boehner is not held back by the fact that he is also not an economist.)
It’s a strange form of reasoning. Very few of us are scientists, which is exactly why we tend to defer to scientific judgment. It might make sense to question expert consensus in a field where you are an expert, but if you know very little about it, you probably want to just go along with what the experts think. Scientists do, in fact, have a nearly unanimous view of anthropogenic global warming. Scientists likewise believe that chugging Liquid Drano is bad for your health, which is why, precisely because of my lack of scientific training, I hold off on the Drano Cocktails.
