When Earth Turned to Ice: Scientists Unravel 700-Million-Year-Old Climate Puzzle
Volcanic carbon emissions reached an all-time low, triggering a global ice age that lasted for 57 million years. Australian geologists employed plate tectonic modeling to…
Antarctica’s Ice Deception: New Study Reveals Surprising Thinness of Ice Shelves
A new effort aims to more accurately measure the loss of ice shelves in Antarctica. Global ice dams are weakening due to rising temperatures, leading…
Melting Point: Rapid Retreat at Petermann Glacier
Decades of retreat are visible from above, but harder-to-see changes below the waterline could also affect this iconic glacier’s future. Petermann Glacier is one of…
The Himalayas’ Vanishing Act: Underestimated Glacier Loss Unveiled
New research reveals that ice being lost from glaciers that flow into lakes in the Himalayas has been significantly underestimated. This discovery has critical implications…
Retreat of Glacier Edges in Alaska’s Kenai Fjords National Park
As glaciers around the world retreat due to climate change, managers of national parks need to know what’s on the horizon to prepare for the…
New Discovery Signals Rapid Decay in Antarctic Glacier
A gigantic cavity — two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall — growing at the bottom of Thwaites Glacier in…
Machine Learning Helps Predict the Geothermal Heat Flux in Greenland
A paper appearing in Geophysical Research Letters uses machine learning to craft an improved model for understanding geothermal heat flux — heat emanating from the…
New Research Shows Greenland Ice Sheet Movement is Decreasing Despite Warming
A newly published study from the University of Edinburgh shows that the movement of the southwest portion of the Greenland Ice Sheet that terminates on…
Jakobshavn Glacier Sheds a Massive Chunk of Ice
New ESA satellite images show that the fastest-moving glacier in the world (the Jakobshavn glacier) shed a massive chunk of ice measuring around 12.5 square…
New Image Shows the Advance of Hubbard Glacier
New data from the Operational Land Imager on Landsat 8 shows the advance of Hubbard Glacier. Since measurements began in 1895, Alaska’s Hubbard Glacier has…
New Threat to East Antarctic Ice
New research reveals two seafloor gateways that could allow warm ocean water to reach the base of Totten Glacier, raising concerns about how it will…
NASA Data Reveal Subglacial Lakes Refilling in Greenland
New research found evidence of a drained and refilled subglacial lake in Greenland, revealing that surface meltwater can be trapped and stored at the bed…
NASA Study Reveals West Antarctic Glaciers in Irreversible State of Decline
A new study led by NASA researchers presents multiple lines of evidence – incorporating 40 years of observations – that rapidly melting section of the…
British Team Fails to Reach Lake Ellsworth
The British Antarctic Survey (BAS) arrived in western Antarctica earlier in December, preparing for their anticipated mission to drill into Lake Ellsworth, a subglacial lake….
British and American Teams Hunt for Life Under Antarctic Ice
Next week, UK glaciologists are heading to Lake Ellsworth to prepare for a new drilling stage that will start on December 5. They hope to…
NASA ICESat Shows Himalayan Glaciers Have Lost Less Ice Than Worst Estimates
A 2010 study using measurements taken by the Gravity Recovery and Climate Experiment (GRACE) satellite reported that glaciers in the Himalayas and the Tibetan plateau…
Satellites Confirm Extensive Ice Sheet Melt in Greenland
Using data from three independent satellites to analyze the extent of surface melt over Greenland’s ice sheet, NASA and university scientists found that ice melting…
