albedo

[albē′dō] pl. albedos
Etymology: L, albus, white
a whiteness, as a surface reflection.

albedo

the reflectivity of a surface usually expressed as the percentage of radiation reflected e.g. solar radiation reflected from the atmosphere, clouds and the earth's surface. The albedo of an object gives an indication of its composition.

Forests affect climate in three different ways: absorbing the greenhouse gas carbon dioxide from the atmosphere to help keep the planet cool; evaporating water to the atmosphere and increasing cloudiness, which also helps keep the planet cool; and absorbing sunlight (the albedo effect), thus warming the Earth.
