Washington: Arctic sea ice appears to have reached a record low winter-time maximum extent for the second year in a row, according to NASA scientists. The new record low follows record high temperatures in December, January and February around the globe and in the Arctic.
Every year, the cap of frozen seawater floating on top of the Arctic Ocean and its neighbouring 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 14.52 million square kms - 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 14.54 million square kms that occurred last year. The 13 smallest maximum extents on the satellite record have happened in the last 13 years.
