Layzej writes: Arctic sea ice was at a record low maximum extent for the second straight year, according to scientists at the National Snow and Ice Data Center (NSIDC) and NASA. This year's maximum extent is 1.12 million square kilometers below the 1981 to 2010 average of 15.64 million square kilometers. Ice extent increases through autumn and winter, and the maximum typically occurs in mid-March. Sea ice then retreats through spring and summer and shrinks to its smallest or minimum extent typically by mid-September. Ice melt in the region is reducing the transport of warm southern waters brought north by the Atlantic Meridional Overturning Circulation (AMOC). "Some studies suggest that decreased heat flux of warm Atlantic waters could lead to a recovery of all Arctic sea ice in the near future," said NSIDC senior research scientist Julienne Stroeve. "I think it will have more of a winter impact and could lead to a temporary recovery of winter ice extent in the Barents and Kara seas."
