Climate change is going to shift habitable zones northward. There are vast swaths of currently uninhabitable Canadian & Russian permafrost that are about to become pleasant grasslands. Check out a Koppen climate classification map: https://en.wikipedia.org/wiki/K%C3%B6ppen_climate_classification#/media/File:K%C3%B6ppen-Geiger_Climate_Classification_Map.png https://en.wikipedia.org/wiki/K%C3%B6ppen_climate_classifica... The largest areas on earth are Dfc (subarctic), Dwf (hot desert), and EF (ice cap). The pleasant areas - C?? and D?[ab] - are relatively small parts of the earth surface. If climate change lifts the cool-summer zones of earth (those ending in c or d) into warm-summer, it has a lot more headroom to increase human-habitable areas than the heating of already-hot areas. Climate change will likely be good for humanity and fatal for a significant portion of humans. These are not mutually-incompatible statements.
