From my understanding - the more significant factor in global warming is GHG emissions Sure, moving the heat outside makes the environment slightly warmer, but that's nothing compared to the significant amounts of solar energy getting trapped because you made the energy to run your a/c by burning coal or any other fossil fuel (Also - the volume of every place where you could reasonably want A/C is negligible compared to the volume of the earth's atmosphere, so that isn't as much of an issue)
