If the world was just warming, it wouldn't be nearly so much of an issue, I don't think. We could just put a big mylar sheet and block part of the sun. We could do that, I think, in about 20 years, if we really wanted to just get rid of this 1.5degC rise. But we can't, we have the ocean acidification, the desertification, the pollution, the acid rain, the plastic pollution. My point is that it's not really the temperature I'm worried about, it's the everything else.
