Global warming is and has been an undisputed scientific fact for years. It's only self serving politicians backed by oil companies that have been obfuscating the truth.
From
http://www.nyu.edu/classes/siva/archives/001419.html is the following,
"... within the peer reviewed scientific literature, the fact of human induced climate change is taken as beyond dispute. A recent study in the journal Science makes this point pretty strongly. If you look in the Science Citation Index (a relatively authoritative index of the peer reviewed literature) between 1993 and 2003 using the keywords 'climate change' you get 928 results. Of these results there is not a single paper (right, that's 0/928) which argues that changes in climate over the last ~150 years are not influenced by human activity."
I also highly recommend "The Weather Makers" by Tim Flannery
http://www.theweathermakers.com/weathermakers/RFK, Jr. says about "The Weather Makers" that it is "The finest account of the overwhelming science behind global warming. Flannery gives us a terrifying glimpse of the future."
And if nothing else just look up what is happening to the polar bears.

Why? Global warming is destroying their Arctic habitat.
It is time for America to wake up and become reality based and have some respect for science. As for the neocons who say "it's only a theory"? I say step off a 30 story building and see if gravity is only a theory.
