Tiny fossils hold answers to big questions on climate change
(Phys.org)—The western Antarctic Peninsula is one of the fastest warming regions on the planet, and the fastest warming part of the Southern Hemisphere.
A new approach to assessing future sea level rise from ice sheets
Future sea level rise due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than estimated in Climate Change 2007, the Fourth Assessment Report of the IPCC, according to new research from ...
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 ...
Research shows rapid warming on the West Antarctic Ice Sheet
In a discovery that raises further concerns about the future contribution of Antarctica to sea level rise, a new study finds that the western part of the ice sheet is experiencing nearly twice as much warming ...
More ice loss through snowfall on Antarctica
Stronger snowfall increases future ice discharge from Antarctica. Global warming leads to more precipitation as warmer air holds more moisture – hence earlier research suggested the Antarctic ice sheet ...
Massive crevasses and bendable ice affect stability of Antarctic ice shelf, research team finds
Gaping crevasses that penetrate upward from the bottom of the largest remaining ice shelf on the Antarctic Peninsula make it more susceptible to collapse, according to University of Colorado Boulder researchers ...
Why Antarctic sea ice cover has increased under the effects of climate change
The first direct evidence that marked changes to Antarctic sea ice drift have occurred over the last 20 years, in response to changing winds, is published this week in the journal Nature Geoscience. Scient ...
Australia's Antarctic runway melting
Australia said Wednesday it was searching for a new aircraft landing site for planes supplying its three bases in Antarctica because the current runway is melting.
New understanding of Antarctic's weight-loss
(Phys.org)—New data which more accurately measures the rate of ice-melt could help us better understand how Antarctica is changing in the light of global warming.
Ice sheet retreat controlled by the landscape
Ice-sheet retreat can halt temporarily during long phases of climate warming, according to scientists.
Sea-level study shows signs of things to come
Our greenhouse gas emissions up to now have triggered an irreversible warming of the Earth that will cause sea-levels to rise for thousands of years to come, new research has shown.
Warming ocean could start big shift of Antarctic ice
(Phys.org)—Fast-flowing and narrow glaciers have the potential to trigger massive changes in the Antarctic ice sheet and contribute to rapid ice-sheet decay and sea-level rise, a new study has found.
Hidden rift valley discovered beneath West Antarctica reveals new insight into ice loss
Scientists have discovered a one mile deep rift valley hidden beneath the ice in West Antarctica, which they believe is contributing to ice loss from this part of the continent.
Study sheds light on vulnerability of polar ice sheets to modestly warmer climate
(Phys.org) -- A new study by a University of Florida researcher finds that sea level peaked between 18 and 30 feet above current sea level during the last interglacial period approximately 125,000 years ago.
