Scientists find evidence for 'great lake' on Jupiter's moon Europa, potential new habitat for life
In a significant finding in the search for life beyond Earth, scientists from The University of Texas at Austin and elsewhere have discovered what appears to be a body of liquid water the volume of the North ...
Sea-level surge at Antarctica linked to icesheet loss
Sea levels around Antarctica have been rising a third faster than the global average, a clear sign of high meltwater runoff from the continent's icesheet, scientists said on Sunday.
Changing Antarctic winds create new sea level threat
New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated.
Achilles' heel of ice shelves is beneath the water, scientists reveal
New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 per cent of ice loss in some areas.
Why glaciers that flow into the ocean are extremely sensitive to climate
In a new paper published in the journal Nature Geoscience researchers present a new view of iceberg calving that explains the sudden collapse of ice shelves and sudden retreat of tidewater glaciers, observ ...
Disappearing snow increases risk of collapsing ice shelves in Antarctica
A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover. Their collapse would enhance the discharge of ice into ...
West Antarctic ice shelves tearing apart at the seams
A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially ...
1000-year Antarctic Peninsula climate reconstruction provides new insight into accelerating ice melt
A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ...
Study finds warm ocean currents cause majority of ice loss from Antarctica
Reporting this week in the journal Nature, an international team of scientists led by British Antarctic Survey (BAS) has established that warm ocean currents are the dominant cause of recent ice loss from A ...
Climate scientists discover new weak point of the Antarctic ice sheet
The Filchner-Ronne Ice Shelf fringing the Weddell Sea, Antarctica, may start to melt rapidly in this century and no longer act as a barrier for ice streams draining the Antarctic Ice Sheet. These predictions ...
Study: Portions of the West Antarctic Ice Sheet are warming twice as fast as previously thought
(Phys.org)—A new study funded by the National Science Foundation (NSF) finds that the western part of the massive West Antarctic Ice Sheet (WAIS) is experiencing nearly twice as much warming as previously ...
Warm ocean drives most Antarctic ice shelf loss, research shows
Ocean waters melting the undersides of Antarctic ice shelves, not icebergs calving into the sea, are responsible for most of the continent's ice loss, a study by UC Irvine and others has found.
Tohoku tsunami created icebergs in Antarctica
A NASA scientist and her colleagues were able to observe for the first time the power of an earthquake and tsunami to break off large icebergs a hemisphere away.
Canadian Arctic nearly loses entire ice shelf
Two ice shelves that existed before Canada was settled by Europeans diminished significantly this summer, one nearly disappearing altogether, Canadian scientists say in new research.
