[15] [16] Since 2013, Arctic annual mean surface air temperature (SAT) has been at least 1 °C (1.8 °F) warmer than the 1981-2010 mean. In 2016, there were extreme anomalies from January to February with the temperature in the Arctic being estimated to be between 4–5.8 °C (7.2–10.4 °F) more than it was between 1981 and 2010. [17]
Climate models predict that the temperature increase in the Arctic over the next century will continue to be about twice the global average temperature increase. By the end of the 21st century, the annual average temperature in the Arctic is predicted to increase by 2.8 to 7.8 °C (5.0 to 14.0 °F), with more warming in winter (4.3 to 11.4 °C ...
A modeling study of the 52-year period from 1947 to 1999 found a statistically significant trend in Arctic ice volume of −3% per decade; splitting this into wind-forced and temperature forced components shows it to be essentially all caused by the temperature forcing. A computer-based, time-resolved calculation of sea ice volume, fitted to ...
Feedbacks associated with sea ice and snow cover are widely cited as one of the principal causes of terrestrial polar amplification. [12] [13] [14] These feedbacks are particularly noted in local polar amplification, [15] although recent work has shown that the lapse rate feedback is likely equally important to the ice-albedo feedback for Arctic amplification.

The Arctic dipole anomaly is a pressure pattern characterized by high pressure on the arctic regions of North America and low pressure on those of Eurasia. [1] This pattern sometimes replaces the Arctic oscillation and the North Atlantic oscillation . [ 2 ]
"The Arctic air coming through Jan. 15th can be the coldest of the winter so far," Anderson said. "This batch of Arctic air will have a vast zone for fresh snow cover to work with and a direct ...
[8] [9] The sudden release of large amounts of natural gas from methane clathrate deposits in runaway climate change could be a cause of past, future, and present climate changes. In the Arctic Ocean, clathrates can exist in shallower water stabilized by lower temperatures rather than higher pressures; these may potentially be marginally stable ...
The last time the city saw these kinds of wind chills was due to an arctic air mass was just after Christmas 2022, the forecaster noted. Wichita is also expected to see another round of snowfall ...
