Sea Ice Growth Slows In Arctic

Arctic sea ice was at a record low wintertime maximum extent for the second straight year.
Every year, the cap of frozen seawater floating on top of the Arctic Ocean and its neighboring seas melts during the spring and summer and grows back in the fall and winter months, reaching its maximum yearly extent between February and April. On March 24, Arctic sea ice extent peaked at 5.607 million square miles, a new record low winter maximum extent in the satellite record that started in 1979. It is slightly smaller than the previous record low maximum extent of 5.612 million square miles that occurred last year. The new record low follows record high temperatures in December, January and February around the globe and in the Arctic. Scientists say as temperatures in the atmosphere and oceans continue to warm, we can expect to keep seeing smaller wintertime maximums in the future. Watch the video for a NASA visualization that shows the growth of Arctic sea ice from its 2015 summertime minimum extent to its 2016 winter maximum.

Wind patterns in the Arctic during January and February 2016 brought warm air from the south and prevented expansion of the ice cover.

This year's Arctic sea ice maximum extent (shown above) covers an area of 5.607 million square miles, and is the lowest in the satellite record.
