Geographers create ‘easy button’ to calculate river flows from space
The frustrated attempts of a UCLA graduate student to quantify the amount of water draining from Greenland's melting ice sheet led him to devise...
Greenland’s fastest glacier reaches record speeds
Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest...
Greenland ice sheet stores liquid water year-round
National Science Foundation-funded researchers at the University of Utah have discovered a previously unknown aquifer in the Greenland ice sheet that holds liquid water...
Arctic a source of atmospheric carbon
For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007,...
Greenland’s shrunken ice sheet: We’ve been here before
Think Greenland’s ice sheet is small today? It was smaller — as small as it has ever been in recent history — from 3-5,000 years...
The tundra — a dark horse in planet Earth’s greenhouse gas...
Vast areas on the Northern Hemisphere are covered by tundra. Here, dwarf shrubs, sedges, mosses etc. thrive on top of permafrost in areas where...
NASA Data Reveals Mega-Canyon under Greenland Ice Sheet
Data from a NASA airborne science mission reveals evidence of a large and previously unknown canyon hidden under a mile of Greenland ice. The canyon...
New drilling technique helps reveal the ‘plumbing’ beneath the Greenland Ice...
Scientists' understanding of how Greenland Ice Sheet melt water travels in passages along the bedrock below fails to account for some key processes. This,...
Ancient ice melt unearthed in Antarctic mud
Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately...
Greenland ice sheet to continue push of sea-level
New research has shown surface ice melt will be the dominant process controlling ice-loss from Greenland. As outlet glaciers retreat inland the other process,...
