Main factors affecting climate
Main factors affecting climate This animation shows the global advance and retreat of daily snow cover along with daily sea ice surface temperature over North America from September 2002 through May 2003. The ice-covered areas modify the radiation budget by means of their high reflectivity. Research shows that the global radiation budget at 18,000 B.P was about 7- -10% less than that of today.
