That might work, except that there would either have to be hundreds of millions of air conditioners or a few thousand VERY LARGE, VERY POWERFUL air conditioners. And who's going to pay for this? I think we'd be better off creating a giant "asteroid" satellite, sending it off into space to collect useful information for a few years, then bringing it back to Earth at maximum speed to impact and knock the planet into a slightly cooler orbit. It would be like a self-induced "Armegeddeon" or "Deep Impact," only it would make people happy. Of course, the angle of the satellite trajectory would have to be finely calculated so that it wouldn't do any of the following:

1. Knock the Earth out of orbit with life-sustaining temperatures.
2. Knock the Earth out of orbit altogether.
3. Split the Earth in half, or some other fraction with multiple pieces.
4. Kill many people.

Of course, some people would *have* to die, but it's a worthy sacrifice in the name of personal comfort. Just aim that sucker at a mildly unpopulated tribal area in Africa, and those savages will never know what hit 'em. And this solution is mostly permanent, or will at least suffice for OUR lifetimes, and we can let later generations deal with their own problems. As a nice bonus, the space program that launched the asteroid could open up a classy resort in the crater afterward. I bet there's a big tourist demand for checking out massive holes in the ground.
