The polar regions as components of the global climate system
> The Arctic and Antarctic are the cooling chambers of our planet. Having a very limited supply of solar radiation, they attract warm air and ocean currents from the tropics, cool them down and send them back towards the equator as floating ice. In this way, the polar regions regulate the distribution of heat on the Earth. This mechanism will only continue to function smoothly, however, if the interactions between sea ice, glaciers, ocean and atmosphere do not change.
