Read a summary of an interesting scientific paper: Seems all the Persian Gulf countries are not going to be habitable in 30 years. Saudi Arabia, Qatar, UEA, and Iran will have high humidity and high enough summer temperatures that most people outside AC will die of heat stroke. You can survive if the humidity is low, because you can cool yourself by sweating. But they are so close to the shallow and very hot Persian Gulf that the humidity will be too hot to cool by sweating. Water in the Gulf is already about 95 F.

People living in air conditioned houses will die en masse when the power fails, so that will be a brief respite. I'll probably live to see it, too. Should have some interesting political consequences.
