I get the impression that a lot of people in the west just assumed that the climate crisis would largely affect the global south, and they'd be fine. What they didn't consider is that some of the worst effects are going to be happening precisely where temperatures diverge significantly from the peak global temperature creating high energy gradients. In countries where temperature is already close to the global peak, the weather will stay relatively stable. Excess energy is going to flow where the temperatures are lower, and that's going to create a lot of rapid heating and unstable weather which these biosystems aren't prepared for.
