>You cannot cool down a building without making the exterior even warmer -- this is the second law of thermodynamics. The Problem is not "solved" by producing even more energy and thus generating entropy (unusable heat).
I don't understand why this particular total misunderstanding of physics comes up in so many contexts (a lot of anti-evolution types claimed it too in the past). The 2nd Law states that total entropy cannot decrease in a closed system. Yet a bit of reflection should reveal that somehow we manage to decrease local entropy all the time. In turn one may, once or twice, notice an enormous sphere of thermonuclear fusion in the sky that provides most of Earth's primary energy input. And at other times you may have noticed an enormous inky void into which energy can radiate away from Earth. Which should reveal that we in fact live in a locally open system, not a closed one. What controls the local general temperature is the equilibrium between energy input and what is radiated away. That's what greenhouse gasses change.
So no, you're completely and utterly off, AC does not in any way cause any trouble when it comes to the problem of global warming. The energy after all would have been transformed to entropy regardless. What matters is the greenhouse gasses that exist in the atmosphere.
