WebThe albedo of Earth’s surface varies from about 0.1 for the oceans to 0.6–0.9 for ice and clouds—meaning that clouds, snow, and ice are good radiation reflectors while liquid water is not. This is because clouds, snow, and ice have multiple layers that reflect radiation, whereas a body of water reflects only from its surface. Ice–albedo feedback is a positive feedback climate process where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Ice is very reflective, therefore it reflects far more solar energy back to space than the other types of land area or open water. Ice–albedo feedback plays an important role in global climate change. For inst…
