> If the first world population used air conditioning less, it would allow poor people, the third world, who tend to live in environments that are hotter and more subject to costs of climate change, to use air conditioning more without adding more to humanity's carbon footprint. This is not the only way. We could also produce cleaner energy in the first world by e.g. building nuclear, solar and (probably off-shore) wind. Then those of us in the first world and the poor of the third world could have the life-saving AC technology, and maybe make the third world a bit richer in the process.
