When I say, "climate change probably isn't the big damned hairy deal everyone makes it out to be," people often dismiss me as a crackpot. Which I suppose is fine, because I am*. But when Freeman Dyson does it, well, obviously they call him a crackpot too, but he's a crackpot who understands all the math that shores up the climate models everyone's so up in arms about. In other words, cracked pots can hold water too if the crack is nowhere important. I'm damned certain his cracks are nowhere near as important as, well, his water, as it were**.
At any rate, read the whole thing, it's an intriguing counterpoint from someone who knows his stuff and doesn't care what anyone else thinks.
* Well, actually I prefer the term, "bomb thrower," but crackpot'll do in a pinch.
