I'm sure by now I have established myself as no genius, but I'm having a hard time wrapping my arms around the idea of this "polar ice-cap mirror" theory. I'm pretty sure, if I remember right, that the most direct sunlight strikes a fairly large protion of the Earth called "the equator." The latest theory on global warming that I have heard is that if the polar icecaps melt, it won't be the "waterworld" scenario, but the Earth will overheat because the polar icecaps cannot reflect the sun's rays back into space. It seems to me that the poles, north and south, are both pretty dark places. I was just wondering if anybody could really explain that theory in laymen's terms
