A U Turn on Climate Change in the U.S.?

The Observer reports that the U.S. is about to make a “historic shift” in its position on global warming. One wonders how this will relate to the Canadian politics of the issue. The issue is growing in importance to Canadians and Dion already has the high ground (particularly after the string of ominous environmental news we’ve had these past few weeks). Meanwhile, Harper has replaced the Ambrose train-wreck with his attack dog Baird, signalling to Canadians that he cares more about the politics of the issue than the policy. I suspect recent events will leave Harper quite isolated on the issue if Bush moves to the center.
