The climate of the Arctic is characterized by long, cold winters and short, cool summers. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. Some parts of the Arctic are covered by ice (sea ice, glacial ice, or snow) year-round, and nearly all ...
The Arctic region is especially vulnerable to the effects of any climate change, as has become apparent with the reduction of sea ice in recent years. Climate models predict much greater climate change in the Arctic than the global average, [46] resulting in significant international attention to the region. In particular, there are concerns ...
The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month a polar climate has an average temperature of less than 10 °C (50 °F). Regions with a polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles, and in this case, winter ...
Climate and vegetation interactions in the Arctic. Papaver radicatum (arctic poppy), a flowering plant of the Arctic tundra follows the sun around the sky during the 24-hour daylight of summer north of the Arctic Circle. Changing climate conditions are amplified in polar regions and northern high-latitude areas are projected to warm at twice ...
Annual precipitation can exceed 5,000 mm (196.9 in) in mountain areas near the coast. Lurøy Municipality at the Arctic Circle gets 3,066 mm (120.7 in) annually, a remarkable amount for a polar location. Precipitation is heaviest in late autumn and winter along the coast, while April to June is the driest.
The climate in the extreme north of Alaska is what would be expected for an area north of the Arctic Circle. It is an Arctic climate (Köppen EF) with long, very cold winters and short, cool summers. The sun does not rise at all during some weeks in the winter, and is out for 24 hours during some weeks in the summer.
The Arctic Archipelago, also known as the Canadian Arctic Archipelago, is an archipelago lying to the north of the Canadian continental mainland, excluding Greenland (an autonomous territory of Denmark) and Iceland (an independent country). Situated in the northern extremity of North America and covering about 1,424,500 km 2 (550,000 sq mi ...
Due to climate change in the Arctic, this polar region is expected to become "profoundly different" by 2050. [1]: 2321 The speed of change is "among the highest in the world", [1]: 2321 with the rate of warming being 3-4 times faster than the global average. [2][3][4][5] This warming has already resulted in the profound Arctic sea ice decline ...
