  • About the Greenland Ice Sheet - National Snow and Ice Data Center
    Greenland has been covered in ice for more than 18 million years; the current ice can be as old as 100,000 years old Together, the Antarctic and Greenland ice sheets contain more than 99 percent of the freshwater ice on Earth
  • Ice Sheet Quick Facts - National Snow and Ice Data Center
    The Greenland Ice Sheet contains about 2 9 million cubic kilometers (0 7 million cubic miles) of ice The ice sheet extends about 1 7 million square kilometers (656,000 square miles), covering 80 percent of the world’s largest island, and is equivalent to about three times the size of Texas
  • Ice Sheets Today - National Snow and Ice Data Center
    Ice Sheets Today offers the latest satellite data and scientific analyses on surface melting of the Greenland Ice Sheet in the Northern Hemisphere and Antarctic Ice Sheet in the Southern Hemisphere Surface melt on each ice sheet results from a combination of daily weather conditions and the amount of solar energy absorbed by its snow and ice
  • Glacier Quick Facts | National Snow and Ice Data Center
    How much glacial ice is on Earth? Presently, 10 percent of land area on Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica Glacierized areas cover over 15 million square kilometers (5 8 million square miles)
  • An intense Greenland melt season: 2012 in review
    Greenland's surface melting in 2012 was intense, far in excess of any earlier year in the satellite record since 1979 In July 2012, a very unusual weather event occurred For a few days, 97% of the entire ice sheet indicated surface melting
  • Large ice loss on the Greenland Ice Sheet in 2019
    The left maps shows total snowfall and rainfall, if any, minus runoff or evaporation, which is the Surface Mass Balance (SMB) for the Greenland ice sheet SMB spans from September 2018 to August 2019, shown in number of millimeters (0 04 inches) of equivalent water amount on the surface
  • Greenlands 2020 melt season in review - National Snow and Ice Data Center
    The 2020 melt season in Greenland is over, finishing thirteenth for cumulative melt-day extent in the 42-year satellite record Melt extent was greater than any year prior to 2002, with about 70 percent of the ice sheet experiencing some melting
  • Ice Sheets - National Snow and Ice Data Center
    Together, the Antarctic and Greenland Ice Sheets contain more than 99 percent of the land ice and over 68 percent of the fresh water on Earth Due to human-caused climate change warming the Earth’s air and ocean, the Greenland Ice Sheet has lost substantial ice mass during the 21st century, with annual losses occurring every year since 1998
