Paul Krugman + Al Gore = The Way Forward

Your entitled to your own opinions, your not entitled to your own realities. Carbon dioxide and other gases is not right wing or left wing. Gore is listening to the majority of scientists, not political ideology. Bush and most major oil companies have realized that global warming is real.
Some of the "solutions" are not conventional green politics (ie nuclear, clean coal). Shooting a hole in your part of the row boat is not defensible. Melting icecaps don't care about the economy. Not working towards a global warming solution is not sane.
