Ice–albedo feedback
Diagram of ice–albedo feedback. Ice reflects more light back into space, whereas land and water absorb more of the sunlight. Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far more solar energy …
