"The level and extensiveness of the frigid air may be tough to match the rest of the winter," forecasters warned. Heavy snow, dangerously low temperatures put more than 70M under winter storm warnings
Some of the ice survives from one year to the next. Currently, 28% of Arctic basin sea ice is multi-year ice, [2] thicker than seasonal ice: up to 3–4 m (9.8–13.1 ft) thick over large areas, with ridges up to 20 m (65.6 ft) thick. Besides the regular seasonal cycle there has been an underlying trend of declining sea ice in the Arctic in ...
The first sea ice-free September could occur as early as the 2030s, the study found. Arctic sea ice has been declining for decades but has shrunk at an even faster rate in the past 20 years.
The decline of sea ice in the Arctic has been accelerating during the early twenty-first century, with a decline rate of 4.7% per decade (it has declined over 50% since the first satellite records). [ 48 ] [ 49 ] [ 50 ] Summertime sea ice will likely cease to exist sometime during the 21st century.
For now, at least, the north pole is covered in sea ice 365 days per year. If C02 emissions are reduced considerably moving forward, ice will remain in the Arctic over most summer months.
The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research.NSIDC archives and distributes digital and analog snow and ice data and also maintains information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores.
Ice sheets have been observed to form later, separate earlier, and rapidly decline in age, thickness distribution and regional coverage. [7] The ice in the southern Beaufort Sea separates 7 weeks earlier than it used to during 1964 to 1974. [7] An instance of climate change contributing to ice loss was the 13th most extreme Arctic storm ...
The icy landscape of the Arctic as we imagine it will no longer exist in just a few decades, researchers returning from a major expedition to the frozen north have warned. Researchers involved in ...
