Ice and snow albedo-temperature feedback

From Glossary of Meteorology

ice and snow albedo–temperature feedback

A positive feedback mechanism involving ice and snow cover, surface albedo, and temperature.

For example, given an initial warming, a decrease in snow and ice cover occurs, lowering the surface albedo. This causes an increase in the absorption of solar radiation, which amplifies the initial increase in temperature.
