The Cato Gang really went off the edge recently with their ad (pdf) in the New York Times, claiming that:
temperature changes over the past century have been episodic and modest and there has been no net global warming for over a decade now.1,2 … The computer models forecasting rapid temperature change abjectly fail to explain recent climate behavior.4
My (two) thousand words’ worth:
The folks at RealClimate have eviscerated their footnotes, pointing out that the studies and scientists they cite don’t support their statements. (Think: cherry-pick, quote out of context, ignore direct contradictions.)
These guys are more than welcome to ask whether limiting greenhouse gases–at great expense–is the best solution to the problem we’re facing. But instead they’re squeezing their eyes closed, holding their hands over their ears, and humming loudly. LALALALALALALALALALA!
