An interesting development, to say the least.
I still think Monbiot is more loon than not, and Anthropogenic Global Warming more scam than threat (I think it possible that the earth has warmed slightly, but regard the case for this possible warming trend being man-made as far from proven). But at least some hardcore greens are beginning to realize that if you really want to reduce carbon emissions without wrecking the world economy, nuclear is the way to go.
On a related note, for my latest Japan update (including news on the Fukushima Daiichi reactors) go here.
