Massive Asteroid Impact Crater in Greenland Occurred a Few Million Years After Dinosaurs Went Extinct
Danish and Swedish researchers have dated the enormous Hiawatha impact crater, a 31 km-wide meteorite crater buried under a kilometer of Greenlandic ice. The dating…
Accelerating Melt Rate Makes Greenland Ice Sheet World’s Largest “Dam” – Generating Huge Amounts of Heat From Hydropower
The world’s second-largest ice sheet is melting from the bottom up – and generating huge amounts of heat from hydropower. Researchers have observed extremely high…
NASA “Oceans Melting Greenland” Mission Complete – Six Years of Mapping Unknown Terrain
To learn how ocean water is melting glaciers, NASA’s Oceans Melting Greenland mission extensively surveyed the coastline of the world’s largest island. The most important…
Exploring Earth From Space: The Stunningly Beautiful Kangerlussuaq Glacier
The Kangerlussuaq Glacier, one of Greenland’s largest tidewater outlet glaciers, is pictured in this false-color image captured by the Copernicus Sentinel-1 mission. Meaning ‘large fjord’…
Satellite Monitoring of Greenland Ice Melting Highlights Increasing Global Flood Risk
Global warming has caused extreme ice melting events in Greenland to become more frequent and intense over the past 40 years, raising sea levels and…
Increased Global Flood Risk Due to Intense Frequency of Extreme Ice Melting in Greenland
Global warming has caused extreme ice melting events in Greenland to become more frequent and more intense over the past 40 years according to new…
Unusual Snowfall in Greenland – “A Dramatic End to a Season of Extreme Events”
The remnants of Hurricane Larry dropped abundant snowfall on Greenland just as the summer melt season was coming to an end. Hurricanes are known for…
A Recent Reversal Discovered in the Response of Greenland’s Ice Caps to Climate Change
Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is…
Water Blisters Trapped Beneath Greenland’s Thick Ice Sheet Could Provide Critical Hydrological Insight
Water “blisters” trapped beneath the thick interior of Greenland’s ice sheet could provide critical insight into the hydrological network coursing deep below Earth’s second largest…
Rain and Warmth Trigger Intense Melting in Greenland
The island’s vast ice sheet underwent multiple bouts of widespread melting this summer, exacerbated in August 2021 by rain. The Greenland Ice Sheet underwent two…
Surprisingly High Levels of Toxic Mercury Discovered in Greenland Glacial Meltwaters
New research from Florida State University shows that concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are…
Clear Signs That Part of the Greenland Ice Sheet Is Close to a Tipping Point
An analysis of the melt situation on the Central-Western Greenland ice sheet reveals clear signs of tipping. Data from the Jakobshavn drainage basin of the…
Can Extreme Melt Destabilize Ice Sheets? A Continental-Scale Picture
Nearly a decade ago, global news outlets reported vast ice melt in the Arctic as sapphire lakes glimmered across the previously frozen Greenland Ice Sheet,…
NASA Astrobiology: Probing for Life in the Icy Crusts of Ocean Worlds
A technique for scanning Mars rocks for microscopic fossils of ancient life is also being developed to hunt for microbes in the deep ice of…
What a Glacial River Reveals About the Greenland Ice Sheet and Global Sea Level Rise
With data from a 2016 expedition, scientists supported by NASA are shedding more light into the complex processes under the Greenland Ice Sheet that control…
Thick Sea-Ice Warms Greenland Fjords
A new study shows that thick sea-ice can increase the sensitivity of Greenlandic fjords to climate warming. Understanding the factors that control how fast glaciers…
Satellite Data Shows Lakes on Greenland Ice Sheet Can Drain Huge Amounts of Water, Even in Winter
Using satellite data to ‘see in the dark’, researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter,…
