With 2), there's still something I don't get... and this applies just as much to your answer as to any answers you would get from climate science, since clouds are clouds (i.e droplets of water), and water vapour is a gas, so their back - radiation explanation doesn't even apply in the case of clouds (not saying it physically could apply anywhere but hopefully you get what I mean)... what I don't get is, you liken them to a blanket, but a blanket is next to you, clouds are separated from the surface by quite a bit of atmosphere — so why is it warmer the next morning at the surface when the clouds are there?
