RealClimate hitting repeated home runs

I know I link to RealClimate a lot, but the site has been running a lot of excellent articles lately. David Archer gently, and without a priori dismissal, critiques James Lovelock's despairing end-of-civilization book; Gavin Schmidt explains the problems with Richard Lindzen's climate-skeptic testimony (and in the comments, Tom Fiddaman makes a fascinating point about use of the Seventies Limits to Growth report as a strawman); Ray Pierrehumbert uses Darwin's birthday and recent discussions of evolution as a jumping-off point for a meta-discussion of global warming's status as a scientific theory.

(Meanwhile, President Bush, like Senator Inhofe, seems to prefer the authority of Michael Crichton on the subject, at least if you can believe Fred Barnes.)
