Funny. Al Gore received a Nobel Peace prize, not a science based Nobel prize, for his work in Global warming. Meanwhile, a Nobel prize winning physicist, Ivar Giaever, has resigned over the farce that is Global Warming.
He is upset over the use of the word "incontrovertible" to describe the facts for the case of Global Warming. The article is worth reading as he describe how nothing is "incontrovertible" in science.
If you agree with Al Gore, you do know he can't even graph correctly? Right?
And for some good videos on Global Warming and CO2, try this four part video collection.
