Although the polar regions radiate away more heat energy than they receive by insulation in the course of a year, what prevents them from becoming progressively colder each year?

Question

Quizplus · Accepted Answer

The circulation of heat by the atmosphere and oceans prevents the polar regions from becoming progressively colder each year. Despite the fact that they radiate away more heat energy than they receive by insulation, the transfer of heat from the tropics towards the poles helps to keep the polar regions from getting too cold. Circulation of heat is driven by winds and ocean currents, which transport heat from warmer regions towards the colder regions. This helps to maintain a balance in the Earth's temperature.
