Blowing hot and cold

Since I, in common with most environmentalists, am not a scientist, I won't try to explain the absurdity of attempting to reduce "carbon footprints". Here's a hint, though: carbon dioxide is not a significant greenhouse gas.

I'll believe the predictions of global catastrophe when scientists understand the climate well enough to a) predict what the local weather will be next week; b) explain the enormous fluctuations in climate over past aeons; c) determine just what the optimum temperature is, so that each of us can know whether global warming, or global cooling, or global stasis, is good or bad, with respect to our own location.
