Another “warm” and slow freeze season in the #Arctic. Sea ice extent is the 2nd lowest on record for the date (2016 – lowest) & 1.9 million km^2 below the 1980s average… https://twitter.com/ZLabe/status/932663163476045825 Arctic Sea Ice Extent/Concentration http://sites.uci.edu/zlabe/arctic-sea-ice-extentconcentration Sound effects by http://TrailerMusicAcademy.com
The Greenland ice sheet is one of the largest contributors to global sea level rise, and if completely melted, could add ~7 meters to sea level. In recent years, the imbalance of the ice sheet has increased with warmer atmospheric conditions. In this talk, Visiting Assistant Professor Samiah Moustafa describes the field’s current knowledge on…

Two of the frozen continent’s fastest-moving glaciers are shedding an increasing amount of ice into the Amundsen Sea each year. https://www.nytimes.com/interactive/2017/10/26/climate/antarctica-glaciers-melt.html
Totten Glacier, the largest glacier in East Antarctica, is being melted from below by warm water that reaches the ice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice…
NASA scientists and ice sheet modelers, Ryan Walker and Christine Dow, traveled to a remote location on the coast of Antarctica to investigate how tides affect the movement and stability of the Nansen Ice Shelf, a 695-mile extension of ice protruding into Antarctica’s Ross Sea. Relatively understudied, Nansen’s manageable size lends itself to becoming a…
