Earth albedo
WebMar 23, 2024 · Albedo effect and global warming feedback loop. If the earth's albedo decreases, it will create warmer climates. Warmer climates melt sea ice and lower the average seasonal snowfall, lowering the earth's albedo. This is precisely a positive feedback loop. 👉 It is challenging to stop global warming since it is causing a decrease in … WebMar 3, 2024 · Since earth reflects about one-third of solar radiation, the average albedo of earth is 0.30. Solar radiation that is not reflected, is absorbed. This is why light-colored surfaces stay...
