"WebDec 17, 2024 · While tweaking Earth’s albedo on high can have global ramifications, changes in albedo at Earth’s surface can have significant regional effects. Dust or soot on a snowpack can cause it to melt faster than normal ( 1 ), shifting the times when runoff occurs—which, in turn, could affect farmers and cities downstream that rely on that water.

The oceans hold 1.3 billion km3, and 71 km3 is fresh water, of which more than two thirds is in the form of snow or ice. The Sun plays a key role in the hydrological cycle, constantly evaporating water into the atmosphere. Some of that water is returned as rain, snow ...

WebJan 10, 2024 · Albedo can range from a value of 0 (no reflection) to a value of 1 (100% reflection). Forests, oceans, cities, deserts all have different albedos. Forests have albedos of between 0.08 and 0.15; deserts have an albedo of about 0.30. Bright snow and ice reflect sunlight back into space; the albedo of snow and ice is between 0.6 to 0.9.
