In terms of the Earth's climate, which has the most albedo?

• Clean snow

• Oceans

• Forests

• Dirt

As the Earth's temperature rises, the polar ice caps melt and shrink. This exposes more ocean which has low reflectivity. So more of the Sun's energy is absorbed and the Earth's temperature goes up even more. This is called what?

• Eutrophication

• Global Warming

• Desertification

• El Nino
