The Barents–Kara Ice Sheet was an ice sheet which existed during the Weichselian Glaciation.It is named after the seas it was centred upon: Barents Sea and Kara Sea.The ice sheet covered the Pechora Sea, the southeastern part of the Barents Sea, Novaya Zemlya and the Kara Sea, likely reaching up to Svalbard and Franz Joseph Land in the north.
Barents Sea is the fastest-warming part of the Arctic, and some assessments now treat Barents sea ice as a separate tipping point from the rest of the Arctic sea ice, suggesting that it could permanently disappear once the global warming exceeds 1.5 degrees. [10]
The Barents Sea (/ ˈ b ær ə n t s / BARR-ənts, also US: / ˈ b ɑːr ə n t s / BAR-ənts; [1] Norwegian: Barentshavet, Urban East Norwegian: [ˈbɑ̀ːrəntsˌhɑːvə]; [2] Russian: Баренцево море, romanized: Barentsevo More) is a marginal sea of the Arctic Ocean, [3] located off the northern coasts of Norway and Russia and divided between Norwegian and Russian territorial ...
The first study proposing a connection between floating ice decline in the Barents Sea and the neighbouring Kara Sea and more intense winters in Europe was published in 2010, [63] and there has been extensive research into this subject since then.
During deglaciation between about 19– 8 ka, sea level rose at extremely high rates as the result of the rapid melting of the British-Irish Sea, Fennoscandian, Laurentide, Barents-Kara, Patagonian, Innuitian ice sheets and parts of the Antarctic ice sheet. At the onset of deglaciation about 19,000 years ago, a brief, at most 500-year long ...
To the west of the Kara Gate is the southeastern part of the Pechora Sea, which freezes in winter when the influence of Atlantic cyclones and warm currents in the Barents Sea weakens. The presence or absence of ice cover in the strait usually coincides with its presence in the Pechora Sea to the west-southwest of it.
This is because the Barents Sea is already the fastest-warming part of the Arctic: in 2021-2022 it was found that while the warming within the Arctic Circle has already been nearly four times faster than the global average since 1979, [44] [45] Barents Sea warmed up to seven times faster than the global average.
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]
