Global warming is a beautiful phenomenom. It will regulate the growth of the users - mainly us, the Chinese and the Indians. Humans will adapt to a new world just as they have for about four million years. Oh, there were a few setbacks - Attila, Hannibal, The Plague, Idi Amin, and Hitler to name a few.
Just move inland a coupla miles, maybe a little north of where you are now. (Our Australian, Kiwi, and South African friends should make that shift to the south.) Everyone will be fine, except those who won't adapt.
Enjoy your life. Reject anxiety caused by worrying about things you can't change. You certainly can't change the way people think (or don't think) judging by the evidence that people here used to form their conclusions.
Have a warm, sunny nice day.
