That seems like the current conclusion. But as people start dying, the population should decrease and that will limit global warming. Life as humans knew it has already ended, and civilization as we know it might end, but shouldn't mankind and civilization still survive pretty well? (Legitimate question)
I'm not sure what to make of that question. I think part of what makes civilization "civil" is that we don't accept huge swaths of the human population dying horrible deaths so that a lucky and rich portion of the human population can survive.
