From WorldChanging:

I don’t want to be a big cynic about this, but really, at this point, who WANTS George W Bush to get all interested in climate change? Sooner or later, that guy poisons everything he touches. He’d probably start a highly secretive and utterly disorganized “Department of Greenhouse Security,” where Bechtel apparatchiks took over abandoned army bases to install leaky nuclear power plants in dead of night with extraordinarily-rendered, off-the-books, union-busting labor. Would that help? If he fought the Greenhouse in utter sincerity and with all his might, would he win?

He forgot to mention that Karl Rove would be running a covert smear campaign against Michael Crichton, but otherwise I think he nailed it.
