Greenland’s Snow and Ice started melting in early April this year, weeks earlier than normal. Unprecedented early surface melting is well underway on the southeastern coastline now. | Greenland’s Snow and Ice started melting in early April this year, weeks earlier than normal.

=====Arctic Sea Ice Minimum 2019===== | |||
[https://svs.gsfc.nasa.gov/4757 NASA 3/19/19] | |||
The extent of Arctic sea ice at the end of this summer was effectively tied with 2007 and 2016 for second lowest since satellite monitoring began. An analysis of satellite data by NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder shows that the 2019 minimum extent, which was likely reached on Sept. 18, measured 1.60 million square miles (4.15 million square kilometers). | |||
In this animation, the daily Arctic sea ice and seasonal land cover change progress through time, from the yearly maximum ice extent on March 13, 2019, through its minimum on September 18, 2019. Over the water, Arctic sea ice changes from day to day showing a running 3-day minimum sea ice concentration in the region where the concentration is greater than 15%. The blueish white color of the sea ice is derived from a 3-day running minimum of the AMSR2 89 GHz brightness temperature. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. | |||
