The trade offs get really funny.

If we think it's really the case that most wild animals will perish in the climate upheaval, then doesn't that change the math a bit on how much risk we should be willing to accept when it comes to climate engineering? If the wealthiest humans could probably adapt to +5c, but a billion poorer ones would die, how much does that change the math?

Personally I'd be willing to accept quite a lot of risk to avoid these awful outcomes.

AFAIK the plans to put sulfur into the stratosphere are modeled on exactly what a volcano does, i.e. a natural process. Of course it could turn out bad, but it doesn't sound to me like a totally out-of-bounds idea.

Maybe someone with a better background could tell me otherwise? I only know about computers.
