The issue with climate change is that we have invested a lot of time and money farming our crops where they are, not in the sahel. So as places such as farming regions in western India fall further into desertification this leads to food insecurity rather than a shifting of labor around what is most suitable to farm given climate change. Some life will in fact “win” given climate change increasing temperatures and metabolism but this won’t be human life. It will be microbial or insect life that will probably go on to plague us with a greater abundance.
