Charles,

I’m not arguing against Climate Change, or against acting on it. I’m only arguing against the effectiveness of this particular argument. It’s a variation of Pascal’s Wager, and nobody is ever convinced by Pascal’s Wager.

Thanos,

I don’t have a “breakpoint” for Pascal’s Wager, because Pascal’s Wager is a stupid argument. We need to move to more efficient technologies because CO2 emissions are screwing up the environment; we need to weigh costs and benefits and make good decisions as to how much to cut emissions and what policies to use to get it done — but you’re never going to convince anybody to do so through Pascal’s Wager.
