How does sea ice help cool the Arctic and Antarctic?
ClimatePolar regions
Quick Answer
Sea ice reflects much of the Sun’s energy back to space, keeping polar regions colder. It also insulates the ocean from the air above.
The Full Story
Sea ice has a high albedo, meaning it reflects far more sunlight than dark open water. This reflection helps keep the polar climate cooler and slows further warming. Sea ice also acts as an insulating lid, reducing heat loss from the ocean to the atmosphere in winter. Because of this, shrinking sea ice can amplify warming through the ice-albedo feedback.
Key Facts
1.Sea ice reflects much more sunlight than open ocean
2.Sea ice insulates the ocean from the atmosphere
3.Loss of ice can accelerate warming through feedback
