CryoSat-2 Arctic sea ice thickness from the NSIDC: CryoSat-2 Arctic sea ice thickness from the European Space Agency: Northern Hemisphere Multisensor Snow Extent: Climate Reanalyzer GFS Arctic Snow Depth: Quick look March 2015 snow depth, from optimal interpolation of NASA IceBridge snow radar and MERRA reanalysis data.

Arctic sea ice extent in January 2020 is sitting ABOVE levels observed in the years 2019, 2018, 2017, 2016, 2015, 2012 (record low extent), 2011, AND 2010.. Can you imagine the likes of The Guardian, for example, ever running with this? All rights reserved. The data and models suggest this will occur between 2030 and 2050. The trapped heat takes a long time to dissipate into the atmosphere, even at this time of the year when the sun creeps above the horizon for little more than an hour or two each day. NOAA Climate.gov based on data from NSIDC, 2020 Arctic sea ice minimum second lowest on record, Arctic sea ice: 2012 record low was 18% smaller than previous record, nearly 50 percent below average, Arctic sea ice winter maximum may be smallest on record, 2019 Arctic Report Card: Visual highlights, 2017 Arctic Report Card: Warm summers challenge Bering Sea pollock, Unexceptional Arctic sea ice maximum in 2020, 2019 Arctic sea ice extent ties for second-lowest summer minimum on record, Climate impacts on walruses may be masked by influence of hunting pressure, Surface melting affected more than half of Greenland Ice Sheet in 2015.
But this is not the only reason the Arctic is warming more than twice as fast as the global average. The Arctic Sea Ice Graphs web site. This also makes it difficult for ice to form.

The sea ice cover is one of the key components of the polar climate system.

Climate change is also pushing more balmy Atlantic currents into the Arctic and breaking up the usual stratification between warm deep waters and the cool surface. What's hot in the news around climate and sea ice and what are scientists talking about now? Scientists are concerned the delayed freeze could amplify feedbacks that accelerate the decline of the ice cap.

Each year’s line traces sea ice extent over the calendar year, starting high in January, rising through the time of the winter maximum around late March, declining through mid-September, and rising again through the rest of the year.
