In Wednesday's Republican Presidential candidate debate, Rick Perry said global warming was one big Ponzi scheme. And that Galileo was burned at the stake for being the climate skeptic of his day. Or something like that. UPDATE: Many readers seem thrown by my attempt at sarcasm. Next time I'll be less subtle. But a direct translation of what I was trying to say is provided by Matthew Yeglesias here:

He [Perry] gave a rambling, incoherent answer to a pretty straightforward question about climate change, insisted on making inflammatory statements about Social Security divorced from any policy point, etc.
