A few months ago I heard from a friend that Karl Rove had met privately with a small group of global warming luminaries that included Bob Corell, and that Rove was listening intently and sympathetically to what they were saying. The article at this link predicts that something big is about to happen, perhaps at Rove's direction. Bizarre as it sounds, I'm inclined to believe it.I blogged on this recently here. I don't normally put too much faith in hearsay, but I also believe there's a grain of truth here. My current theory is that this is a "trial balloon" put out by the administration to see how much screaming and howling there is.
Overall, however, this is not necessarily inconsistent with an evolution in Bush's rhetoric over the past few years. In 2001, he emphasized the uncertainties in our science. As that position moved from shaky to downright untenable, however, his rhetoric shifted to fairness (China hasn't signed on, etc.) and economic (we'll put people out of work). He really doesn't argue the science anymore.
Stay tuned for more!
