Earthâs Albedo and Global Warming This interactive activity adapted from NASA and the U.S. Geological Survey illustrates the concept of albedoâthe measure of how much solar radiation is reflected from Earth's surface. The balance between the amount of solar radiation reflected and absorbed by Earth's surface plays an important role in regulating global temperature.
For this study it seemed appropriate to simply vary the earth's average global surface albedo from today's average. Surface albedo was varied from 0% (absorption of all solar radiation) to 25%. Surface temperatures would be expected to increase for low albedo and decrease for high albedo.
