Climate in the Arctic

In the Arctic, the climate is cold. This is mainly due to the earth being tilted on its axis relative to the sun, which means that less solar radiation reaches the polar regions. In addition, the Arctic is covered by snow and ice much of the year. Snow and ice reflect incoming radiation: they have high albedo. Because of this, most of the sun’s warmth that reaches the bright surface is reflected back to the atmosphere. This helps keep the Arctic cool.
