Former U.S. Vice President Al Gore warned hundreds of U.N. diplomats and staff on Thursday evening about the perils of climate change, claiming: Cigarette smoking is a “significant contributor to global warming!”

Gore, who was introduced by Secretary-General Kofi Annan, said the world faces a “full-scale climate emergency that threatens the future of civilization on earth.”

Then he opened a case of the book he wrote that he’s trying to pawn off on people.

I believe this smoking thing is as reliable as anything else the global warming crowd has put out.
