Granted, I don't spend much time in the pool, but isn't water good at stopping UV rays? I wouldn't think that anything more than a cm underwater...
edit: ah, I screwed up the first time. Now I get 2.5 x 10^66. From 400!/(300!*100!*30!) I used Gosper's approximations to get 400! = 1.3...
Do you really mean "400 choose 100"? If so, it's about 10^425. Edit: Wrong, see below.
My best idea so far is that ice might be a good absorber/emitter of infrared light. Perhaps ice reflects most of the visible light coming in from...
But if the poles absorb more than they emit, they would have to give heat to the temperate zones through convection/conduction, which would mean that...
A black car is hotter than a white one because they absorb more radiant energy than they emitt. I'm arguing that the poles emitt more than they...
The standard line is that ice reflects light well, so losing the ice caps means the Earth will absorb more sunlight, and global temperatures will...
