   Some of it is re-radiated back into space.

   The sort of computer simulation that models the planet as a whole isn't   
   cheap, and not in the least cooperative.   
      
   IEEE Spectrum ran an article "cloud computing" a few years ago on the   
   difficult to making climate simulations fine-grained enough to model   
   cloud cover. Apparently the then current state of the art worked with   
   tiles about 100 miles by 100 miles, and cloud cover was averaged over   
   the entire tile. The ambition was to get down to cloud sized tiles, but   
   that was someway off.
