Mar 25, 2025 · Melting on the Antarctic Ice Sheet for the 2024 to 2025 season began with above average melt extents in all regions, but melt extent dropped to nearly zero or below average from February 1 to March 15. Net accumulation of snow, part of the ice sheet’s surface mass balance, was far above average for the year, helping reduce the ice sheet’s net contribution to sea level rise for this period.

Jan 30, 2025 · In this plot, climate model results show a variety of determinations of melt extent as percent melting of the ice sheet of Antarctica. Hourly melt extent, shown in red, is mapped with a threshold of at least 1/24 of a millimeter generated per hour.

1 day ago · Rapidly melting Antarctic ice would also further contribute to global sea-level rise. No ACC slowdown has actually been observed yet in the real world, but the study shows a concerning trend.

Mar 25, 2025 · Melting on the Antarctic Ice Sheet for the 2024 to 2025 season began with above average melt extents in all regions, but melt extent dropped to nearly zero or below average from February 1 to March 15.

Antarctica is losing ice mass (melting) at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise.

Jan 16, 2025 · Crucial details are beginning to come into focus. The Antarctic ice sheet is nearly twice the area of Australia and holds enough freshwater to raise global sea levels by 58 metres.

2 days ago · A new study found parts of Antartica could pass a tipping point for mass ice sheet losses as soon as 2050 – pushing sea levels 2 metres higher by 2300 than currently predicted.

Jan 22, 2025 · Satellite data from early 2025 revealed extensive melting at Antarctica’s Amery Ice Shelf, highlighting its vulnerability. As a natural barrier against ice flow, its weakening could accelerate sea level rise.

Jan 26, 2025 · At the margins of the Antarctic ice sheet, glaciers flow into the Southern Ocean, forming floating ice shelves. These ice shelves act as keystones, stabilising the ice sheet. They're also...
