A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [1] The climate of the Arctic is characterized by long, cold winters
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.
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 the rate of the global average. [1]
Every year, sea ice cover in the Arctic Ocean shrinks to a low point in mid-September. As the Intergovernmental Panel on Climate Change has shown, carbon dioxide levels in the atmosphere are ...
The Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September.
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 Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The Arctic ice pack undergoes a regular seasonal cycle in which ice melts in spring and summer, reaches a minimum around mid-September, then increases during fall and winter. Summer ice cover in the Arctic is about 50% of winter cover. [1]
The Arctic Last Interglacial climate was highly unstable, with pronounced temperature swings revealed by δ 18 O fluctuations in Greenlandic ice cores, [13] though some of the instability inferred from Greenland ice core project records may be a result of mixing of Last Interglacial ice with ice from the preceding or succeeding glacial ...
