WebThere are a number of feedback processes important to Earth’s climate system and, in particular, its response to external radiative forcing. The most fundamental of these feedback mechanisms involves the loss of longwave radiation to space from the surface. Since this radiative loss increases with increasing surface temperatures according to … WebAlbedo is a very important factor in both weather and climate. The amount of sunlight that is absorbed or reflected is a driving force of our weather. As different surface types absorb …
