[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 ...
More of the Sun's energy is now absorbed in these regions, contributing to amplification of Arctic temperature changes. [90] Arctic amplification is also thawing permafrost, which releases methane and CO 2 into the atmosphere. [91] Climate change can also cause methane releases from wetlands, marine systems, and freshwater systems. [92]
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
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. [16]
[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 ...

Sea surface temperature difference between the decades 1960-1970 and 2010-2020 in degrees C. [1] Location of the Barents Sea in the Arctic Ocean. Atlantification is the increasing influence of Atlantic water in the Arctic. Warmer and saltier Atlantic water is extending its reach northward into the Arctic Ocean. [2]
