Climate change in the Arctic
The Arctic is warming about twice as fast and the global average. This is mainly because melting of snow and ice exposes a darker surface and increases the amount of solar energy absorbed in these areas (albedo effect). This significant regional warming leads to continued loss of sea ice, melting of glaciers and of the Greenland ice cap.
Climate in the Arctic
The Arctic has a cold climate. This is mainly because the earth’s axis is tilted relative to the sun and less solar energy reaches the polar regions. In addition, the Arctic is covered with snow and ice much of the year. Snow and ice have high reflectivity, albedo, which helps keep the Arctic cool.
