1 To be in radiation balance Earth would have to be warmer by about 12C. Clouds cool the planet by reflecting sunlight back into space, much as they chill a summer's day at the beach.  Clouds warm the Earth by absorbing infrared radiation emitted from the surface and reradiating it back down. The process traps heat like a blanket and slows the rate at which the surface can cool. The blanketing effect warms Earth's surface by some 7C.
