While the Antarctic sea ice has expanded beyond levels that researchers have seen in the past, experts point to overall atmospheric changes, including shifts in pressures and winds, which can drive ice formations. TheNational Snow and Ice Data Centerreported that as of Sept. 19, for the first ...

The Antarctic ice sheet has the potential to raise global sea levels by tens of meters. "What we know for certain," said Levermann, "is that not stopping the burning of coal, oil and gas will drive up the risks for coastal metropolises from New York to Mumbai, Hamburg or Shanghai."...

During the Last Interglacial, polar ocean temperatures were likely less than 2°C warmer than today, making it a useful period to study how future global warming might affect ice dynamics and sea levels. "This study shows that we would lose most of the West Antarctic Ice Sheet in awarmer ...
The importance of ice shelves The Antarctic ice sheet contains enough ice to raise global sea-levels byabout 58m(190ft) if it melted entirely. Most is held in East Antarctica, which has been relatively stable in recent years and is not expected to collapse in the near future. ...
CANBERRA, June 14 (Xinhua) -- Ice melt has caused sea levels to rise by 8 mm since 1992, according to leading scientists on Thursday. Australian scientists from the Commonwealth Scientific and Industrial Research Organization (CSIRO) teamed up with international researchers to study the Antarctic ...

Sea-level rise projections rely on accurate predictions of ice mass loss from Antarctica. Climate change promotes greater mass loss by destabilizing ice shelves and accelerating the discharge of upstream grounded ice. Mass loss is further exacerbated by
