Note that I mentioned nothing of saving it. We are well and fucked. How fucked? Couldn’t tell ya, what I can tell you, is that the river outside my house hasn’t frozen in nearly 20 years, and it had frozen every year before that in all of recorded history, some 900 or so years. There used to be annual ice skating races that now happen indoors. I’m not worried about science boundaries and all that. I’m worried about civilization going tits-up once some places get too affected. For example, we are probably less than a decade or so away from certain places with lots and lots of people living there becoming inhospitable. Either they will die, or run into some other country/region that can’t support them, or disperse around the world (most unlikely).
