Vegetation and water also have low albedos. Most of Sun’s radiation is in the shortwave (visible) spectrum. The Earth as a whole reflects about 30% of this radiation back into space (and absorbs the rest, which helps warm the planet). Much of the Earth’s albedo is due to clouds, but land surfaces with high albedos, like ice sheets and snow fields, also contribute. Albedo is important in According to the United Nations Framework Convention on Climate Change, climate change is change in the climate of the whole Earth or a region of the Earth that is believed...
