The Albedo of the Earth

The albedo of the earth

A) Decreases with a warming climate because of clouds that result from increased evaporation of sea water.
B) Is part of a positive feedback cycle, where the increased albedo due to clouds causes a reduction in solar energy that reaches the earth, thus resulting in cooling.
C) Is part of a negative feedback cycle, where the increased albedo due to increased snow and ice coverage increases the effectiveness of solar energy in warming land areas.
D) None of the choices are correct.
