A 3-D View of the Greenland Ice Sheet Opens Window on Ice History

AUSTIN, Texas —  Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate conditions and the … Continue reading

Understanding the Ocean’s Role in Greenland Glacier Melt

The Greenland Ice Sheet is a 1.7 million-square-kilometer, 2-mile thick layer of ice that covers Greenland. Its fate is inextricably linked to our global climate system. In the last 40 years, ice loss from the Greenland Ice Sheet increased four-fold … Continue reading

West Antarctic Glacier Loss Appears Unstoppable

A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in … Continue reading

A Look Back and Ahead at Greenland’s Changing Climate

Over the past two decades, ice loss from the Greenland Ice Sheet increased four-fold contributing to one-quarter of global sea level rise. However, the chain of events and physical processes that contributed to it has remained elusive. One likely trigger … Continue reading

Greenland Ice Stores Liquid Water Year-Round

Potential for Storing Meltwater Important for Calculating Sea-Level Rise Researchers at the University of Utah have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. The … Continue reading

Northern hemisphere losing last dry snow region, says CU study

Last July, something unprecedented in the 34-year satellite record happened: 98 percent of the Greenland Ice Sheet’s surface melted, compared to roughly 50 percent during an average summer. Snow that usually stays frozen and dry turned wet with melt water. … Continue reading

Glaciers Contribute Significant Iron to North Atlantic Ocean

All living organisms rely on iron as an essential nutrient. In the ocean, iron’s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean’s food web. A new study by biogeochemists … Continue reading

Analysis of Greenland Ice Cores Adds to Historical Record and May Provide Glimpse into Climate’s Future

The International North Greenland Eemian Ice Drilling (NEEM) project results indicate that melting of Antarctic ice sheet may have contributed more to sea level rise than melting of the Greeland ice sheet some 100,000 years ago A new study that … Continue reading
