President Bill Clinton is making a surprise appearance at the world climate conference in Montreal. This is causing some consternation among the Bush crowd, since he will undoubtedly call for more progressive action on the US's part to curb emissions. So far, the Bush administration is refusing to even discuss possible strategies for curbing our carbon output. Despite the overwhelming evidence and scientific consensus, they don't believe there is anything to worry about. I've said it before and I'm repeat myself now: the long-term historical opinion of the Bush presidency is going to be very low.
