OK, NASA's James Hansen is the most famous of climatologists. Whether you think he's right or wrong on climate change, though, his government position is giving him the platform to spew rants that democracy is the problem and the Chinese style of dictatorship is the answer (never mind millions of people murdered, eh? And you didn't visit Tibet, I'll bet) for the world's future.
Nobody cares what I think, but, Hey, Doc? You're an ass. Climate change needs to find a spokesman who is at least rational.
