Albedo is the proportion of incident light that is reflected away from a surface.. Diffuse reflection is the reflection of light in many directions, rather than in just one direction like a mirror (specular reflection).. It is an important consideration in climatology since recent Albedo decreases in the Arctic have increased heat absorption at the surface. In the case of ideal diffuse reflection (Lambertian reflectance), incident light is reflected in all directions independently of the angle at which it arrived. Albedo is defined as the ratio of reflected radiation from a surface to the amount of radiation that hits it. One of the reasons why snow and ice can hang around for a long time after they have fallen in winter is … Snow is the highest because it reflects about 95% of radiation. Scientists make hypotheses based on their observations of natural phenomena. Laws are accepted as fact because they are always observed to be true. The Earth's albedo is about 0.37.

She has over 10 years of experience developing STEM curriculum and teaching physics, engineering, and biology. For example, if significant amounts of ice in glaciers and at the North and South pole melt, the average albedo of the Earth could decrease as white, icy areas turn into dark areas of ocean and rock. The amount of cloud cover also affects albedo because clouds reflect heat and light, and they also have a low albedo. The reflecting power of a surface, expressed as a ratio of reflected radiation to incident or incoming radiation; it is sometimes expressed as a percentage. All rights reserved. As they address the root cause of climate change, rising CO2 concentrations, they have relatively low uncertainties and risks. However, these techniques work slowly to reduce global temperatures. 2.
