If the amount of snow and ice in the polar regions of Earth were to decline due to global warming, how would you expect this to affect the radiation budget of Earth?
The percent of radiation reflected from a given surface is the albedo. Snow has one of the highest albedo percentages, in that up to 95% of sunlight may be reflected from the snow surface. If total snow cover on Earth is reduced, the energy that would have been reflected becomes absorbed instead. Increased polar snow and ice melt will result in higher sea levels, which coupled with rising ocean temperatures will cause an increase in evaporation rates that will add more water vapor (a greenhouse gas) to the atmosphere and, subsequently, increase the amount of radiation returned to Earth.
