Albedo -

The next time you see a satellite image of Earth, remember that the brightness of the poles isn't just beautiful scenery; it is the planet's cooling bill. As those whites turn to blues, the bill comes due.

The Earth as a whole has an average albedo of approximately 0.30 , meaning about 30% of the sun's energy is reflected back into space. The Ice-Albedo Feedback Loop Albedo

Several factors influence the albedo of a surface, including: The next time you see a satellite image

In science, is a measure of how much light or radiation a surface reflects. It is expressed on a scale from 0 to 1 , where 0 is a perfectly black surface that absorbs all light and 1 is a perfectly white surface that reflects everything.

Albedo is the measure of reflectivity, a score given to surfaces based on how much sunlight they reject. It is a concept usually reserved for climatologists and astronomers, a decimal point determining the fate of glaciers. But on a winter morning, it is a sensory experience. It is the blinding whiteness that makes you squint, the brilliance that hurts the eyes because it refuses to absorb.
