Latest Ice sheets Stories
WASHINGTON, March 15, 2011 /PRNewswire-USNewswire/ -- Researchers and flight crew arrived in Thule, Greenland, on Monday, March 14, for the start of NASA's 2011 Operation IceBridge, an airborne mission to study changes in Arctic polar ice.
The contribution of Greenland to global sea level change and the mapping of previously unknown basins and mountains beneath the Antarctic Ice Sheet are highlighted in a new film released by Cambridge University this morning.
Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers, according to new research.
Sudden changes in the volume of meltwater contribute more to the acceleration â€“ and eventual loss â€“ of the Greenland ice sheet than the gradual increase of temperature.
Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to climate change.
New climate records recovered from Antarctica during the recent Integrated Ocean Drilling Program (IODP) "Wilkes Land Glacial History" Expedition show that approximately 53 million years ago, Antarctica was a warm, sub-tropical environment.
Ice loss from the Greenland ice sheet, which has been increasing during the past decade over its southern region, is now moving up its northwest coast, according to a new international study.
Ice shelves are retreating in the southern section of the Antarctic Peninsula due to climate change.
The East Antarctic ice sheet, once unaltered by global warming, has swiftly melted since 2006 and could increase sea levels, says a new study.
Satellite observations and a state-of-the art regional atmospheric model have independently confirmed that the Greenland ice sheet is loosing mass at an accelerating rate, reports a new study in Science.
