I'm reminded of a passage from a book I read as a teenager:

Almost all of Earth had grown unbearably hot, from climate changes, and chemicals, and power plants, and fallout. Cool areas had become hot and dry, and hot areas like India had become furnaces, all but unlivable except for special "ice box" cold shelters. There were no trees and no birds, only insects that crawled the baking streets. Death shadowed the Earth, through every turn, through every orbit, all under an impassive sun.
