Climate change - ice and snow and the albedo effect

Year: 2008 Author: Hugo Ahlenius, UNEP/GRID-Arendal
Changes in the polar regions can cause more warming in the entire planet earth system through feedback effects. One such effect is the reduction of ice and snow due to warmer temperatures. When the white and gray snow and ice disappears, less sun rays are reflected out and instead the heat is absorbed by land and sea - which causes further increase in the warming.
