Yeah, but I think the parent posters' concern is that the outcome is "unclear", and I was just pointing out that no matter what happens, the planet will be fine, humans will survive, and our infrastructure is what'll be impacted (and consequently, our lifestyle). None of that is "unclear", I think. It all follows from "temperatures rise" (which the parent concedes as a given). Ice melts. Waters rise. Life changes.
