Climate change: hell freezes over?

According to the Guardian, the Bush Administration is about to reverse its position on climate change, and push for a domestic emissions cap. I'll believe it when I see it, and then I'll believe it when a robust policy is implemented rather than seeing the different branches of the US governmental system using one another as a convenient excuse for inaction. OTOH, is this really surprising? The major oil companies have already changed their position, and this week Exxon-Mobil, the last major holdout, decided that the path of outright Denial was simply embarassing and decided to push for a more serious policy (they also stopped funding their shills in the Competitive Enterprise Institute, which ought to raise the tone of the debate somewhat). When the people who jerk Bush's strings change their position, it will hardly be surprising if he does too.
