I remain unconvinced. That precise argument could have been made in, say, 1930, or 1940, or 1950, and so on. Yet we experienced global cooling between the 1940's and mid 70's.

The Pascal's Wager applies equally well for the wizard example as it does for Kyoto and its variants. It's hardly a sound basis on which to make decisions of enormous import and impact. A better basis would be "first, do no harm"...
