Greenland Ice Sheet meltwater can flow in winter, too
New findings published in Geophysical Research Letters underscore need for year-round investigations of Arctic hydrology.

Scientists discover new mode of ice loss in Greenland
A new study finds that during Greenland’s hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island’s west coast didn’t just melt faster than usual, it slid through the glacier’s interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing. The wave persisted for four months, with ice from upstream continuing to move down to replace the missing mass for at least four more months.

Greenland Ice Sheet melting can cool subtropics and alter climate
A new study finds evidence that the last time Earth was as warm as it is today, cold freshwater from a melting Greenland Ice Sheet circulated in the Atlantic Ocean as far south as Bermuda, elevating sea levels and altering the ocean’s climate and ecosystems.

Researchers make first map of thawed areas under Greenland Ice Sheet
NASA researchers have helped produce the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed – key information in better predicting how the ice sheet will react to a warming climate. Knowing whether Greenland’s ice lies on wet, slippery ground or is anchored to dry, frozen bedrock is essential for predicting how this ice will flow in the future, but scientists have very few direct observations of the thermal conditions beneath the ice sheet.
