Evolution is far slower than the climate has been changing. Many species have, and will suffer these consequences. We’ll probably wait until our food supply is threatened more than just a little unseasonable bird flu to really care.
It is very profitable to be proactive. The climate crisis will cost trillions of dollars to "repair" and deal with. Taking the right steps at the right time is way cheaper. We really are too stupid as a species and it'll be our downfall.
