ice sheets of Antarctica

The ice sheets of Greenland and Antarctica will contribute more to sea-level rise this century than any other source, so stalling the fastest flows of ice into the oceans would buy us a few centuries to deal with ... In Antarctica, by contrast, there is little seasonal melting and much less water below the ice sheet.

Scientists have gathered rock samples from more than four kilometres below Antarctica that could reveal how much - or how little - the oceans will need to warm before the frozen continent's ice sheets melt. The international research team made major new discoveries about the West Antarctic Ice Sheet ...

Kiwi scientists just returned from an ambitious drilling expedition in Antarctica broke more than ice on the frozen continent. The 30-strong research team also broke two records: the highest-ever recovery rate from a deep drill core they sent below the vast West Antarctic Ice Sheet, and the longest-ever piston ...

"Science wasn't mature enough at the time of the IPCC report to really deal with what the Antarctic ice sheet contribution would be, so they largely left it out as a dynamic contribution," said Naish. "If Antarctica does something a bit surprising it could be tens of centimetres more by 2100." Antarctica is trickier ...

The issue is that sea levels keep rising for several hundred years after we stabilize temperatures, largely due to the continued melting of ice sheets in Antarctica and Greenland from the heat already in the climate system. The study considered two scenarios. In the first, human carbon pollution peaks ...

The researchers found that between 2008 and 2015, the East Antarctic Ice Sheet had essentially no change in its rate of ice discharge—ice flow into the ocean. They also confirmed that the flow of West Antarctica's Thwaites and Pine Island glaciers into the ocean continues to accelerate, albeit at a slower ...

The important ice streams in Antarctica are wider, tens of kilometers up to 100 kilometers, but their societal consequences are larger as well, because they could potentially trigger a runaway marine ice sheet collapse. The fast-flowing parts of the ice sheets—the outlet glaciers and ice streams—might be the ...

The first, reported on over at The Guardian, was a proposal for massive engineering projects to slow down the melting of ice sheets in the Antarctic and on Greenland. Published in the latest issue of Nature, and authored by a team led by John C. Moore of the University of Lapland, the research outlines a ...

More of one of Antarctica's largest and most important glaciers is floating on top of the ocean than previously thought, researchers say, which could have a ... "But also there's a contribution of the Antarctic ice sheet — and the Greenland ice sheets actually — so as they melt that ice mass flows into the ...
