You're view of the impact of climate change is surprisingly and disappointingly American centric. The result of doing nothing will be far worse for the world's poor in Africa and Asia than for the American working class if carbon emissions are restricted. Also, if we're waiting for "proof" of the existence of global warming, I image we'll be waiting quite a while. Correct me if I'm wrong, but I don't believe it's possible to prove anything in the physical sciences. Newton's theory of gravity was believed to be correct for over two hundred years before scientists began to suspect that it was inaccurate in certain cases.
