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.
The Arctic Ocean's ability to absorb carbon dioxide from the atmosphere appears to be waning due to melting permafrost and worsening coastal erosion.
Nearly all of the Arctic’s sea ice could melt by the summer of 2027, a group of international scientists has warned. “The climate models show that unless we can stay below 1.5 degrees Celsius ...
This coast has an arctic climate warm enough to allow plant growth in late-June, July and August only, and even then frosts may occur. On the whole this is a damper, wetter area than the Low Arctic tundra ecoregion that continues along the coast west of here to Quebec .
Above average temperatures are favored across much of the country next week, according to the latest forecast from NOAA's Climate Prediction Center. Arctic blast to blanket much of US with below ...
Most of northern Alaska has an Arctic climate with long, extremely cold winters and short, cool summers. The average temperatures during the summer months are only several degrees above freezing and the average temperatures during winter are as low as −20 to −30 °F (−29 to −34 °C), and can dip to −50 to −60 °F (−46 to −51 °C).
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 ...
