OK: how will their respond? Imagine you live in a valley where elderly people die of heat stroke every summer: 100 three years ago, 500 the summer after, 2,000 last summer. Your parents are 70 and 71 and barely made it. You immigrate, with your children, right? To where? The big city with worse heat management? Repeat with peasants who can’t grow crops without expensive feedstock, or pig farmers whose water supply is dry. Where will they go? People will want to flock to places that are currently openly considering tall walls and machine guns to prevent immigration — and that’s when thousands are coming at a time. You think that having several millions every year will not make that situation a lot more tense?
