Climate change feedbacks

thumb|Albedo change in Greenland: The map shows the difference between the amount of sunlight [[Greenland reflected in the summer of 2011 versus the amount it reflected between 2000 and 2006. Some areas reflect close to 20 percent less light than a decade ago.]] Albedo ( ; ) is the fraction of sunlight that is diffusely reflected by a body. It is measured on a scale from 0 (corresponding to a black body that absorbs all incident radiation) to 1 (corresponding to a body that reflects all incident radiation). Surface albedo is defined as the ratio of radiosity Je to the irradiance Ee (flux per u
