One day the calculation is going to be "do nothing and cook ourselves to death" vs. "Put SO2 in the atmosphere and see what happens next".

If the SO2 brings about destruction sooner, I'm of the camp that "well, we were destined for death anyway...".

I can understand a no answer from people who think climate change is no big deal, but it's kind of weird that people who think climate change will kill hundreds of millions -- possibly everyone -- say no on the grounds that it has risks.

Possible unintended side effects is better than "everyone dies".

Ten years ago, I was saying we should experiment with it on a small scale so that if it does become necessary, we're not shooting blind, but even then the doomers were opposed because of "risks". You know what else has risks? Unmitigated climate change!
