The Earth sheds its own heat into outer space via black body radiation, and we can help this process by shedding heat in specific infrared bands that pass right through the atmosphere. We already have radiative cooling paints that do this, and they can achieve sub-ambient air temps in full sunlight:

Yes, and those are really cool and I want some.

We might be able to somehow collect heat (with superconductors? I don't know) and beam it into space, but that still doesn't solve the problem.

Please watch the Bartlett lecture, please?
