U.S. Sen. Ted Stevens says he disagrees with a new scientific study's conclusion that the burning of fossil fuels is a major factor in climate change. Stevens, who is to chair the U.S. Senate Commerce Committee soon, later says he looks forward to reading the report. Does anyone else see the disconnect here? Who are you going to trust to address climate change - a Senator in the back-pocket of the extractive resource industries, or three hundred leading climate scientists?
