Global warming is something that could be catastrophic. You could argue that it’s in the same category because you can’t prove that my life today is worse because of global warming, but it’s something where it could be exponential. The odds are against it, but we don’t even know how to calculate the odds. It’s not like we’re playing blackjack or something like that. There’s more carbon in the Arctic tundra than in the entire atmosphere plus all the rain forests put together. And that carbon, unlike the rain forest where you have to burn the rain forest to release it, goes into the atmosphere as soon as you get melting. It’s already many gigatons per year going up. That’s something that could spiral out of control.
