When I'm reading about climate change in public forums like the internet, or newspapers, I expect to see denial argments all over. Usually, they're the same old shit, that's been roundly debunked by numerous people. So it's a pleasant suprise to find new arguments - it gives you something to think about.
This one really was suprising though: Richard Lindzen is well known for being a good debater, and well-read. He's one of the last deniers that mainstream seems to accept.
