My son just came back from China and said that in Beijing you can never see the sun. I think the physics is all wacky on this co2-warming thing, but there are good reasons not to burn fossil fuel. The solar and wind people can't do math, so sooner or later it's always back to nuclear.
But I think that option is closed to us right now because of gross stupidity. There is something about running a nuclear plant that turns brains to mush. I've seen it first hand. We will only get somewhere when we are in great crisis, and the pudding-heads are swept aside. I give that 10 years.
