Or go underground like some in Australia do (homes built in old opal mines or the like). Earlier this year, I moved to a boat. No A/C, but deck is painted white (as with most boats, for good reason) & if temps get too uncomfortable, water for cooling / swimming is always nearby. :-) I suspect significant % of world population might be forced to seek creative solutions like this in years ahead...
