> The radiation to earth varies already, sometimes we're farther away from the sun and the output of the sun isn't constant either. The earth seems to handle that just fine. That sounds remarkably similar to "how can there be global warming if we still have a cold season and a hot season". I don't say space-based solar arrays are necessarily a problem, but arguing that earth handles variations, as if the net total doesn't matter, is a little blinkered.
