Earth albedo
WebThe difference in albedo between snow-covered and bare forests is at least 0.5. The product of these values indicates a difference in average albedo for the whole earth of 0.017. If the average albedo increases from 0.31 to 0.327 then, other things being equal, the earth’s temperature would increase by 3.8 ºC. WebApr 9, 2024 · Publication Abstracts Jin et al. 2024, submitted.
