Intense melting on the Antarctic Peninsula | National Snow and Ice …
2024年1月23日 · Satellite data through January 15 show strong above average melting in the Larsen C and remnant Larsen B Ice Shelves, with notable melt events in the Brunt and Roi Baudouin Ice Shelves. Melting is on track for near-average to above-average total daily melt for the 2023 to 2024 melt season.
Ice Sheets Today - National Snow and Ice Data Center
2025年1月8日 · Ice Sheets Today offers the latest satellite data and scientific analyses on surface melting of the Greenland Ice Sheet in the Northern Hemisphere and Antarctic Ice Sheet in the Southern Hemisphere. Surface melt on each ice sheet results from a combination of daily weather conditions and the amount of solar energy absorbed by its snow and ice.
Surge in Antarctica's melting as new year arrives
2025年1月8日 · Surface melt extent over the Antarctic Ice Sheet rose sharply again in late December, after a record melt event in mid-December, culminating in all-time record melt extent in the passive microwave satellite record on December 25 and 26, surpassing 3 percent of the ice sheet area. Surface melt remained high into the first few days of the new ...
Antarctic ice sheet: Scientists identify new ‘tipping point ... - CNN
2024年6月25日 · Scientists from the British Antarctic Survey found that warm ocean water is seeping beneath the ice sheet at its “grounding line” — the point at which the ice rises from the seabed and...
Greenland and Antarctic ice sheets are melting rapidly and ... - CNN
2023年4月20日 · The Greenland and Antarctic ice sheets, which hold almost all of the world’s freshwater ice, are shrinking at a frighteningly rapid pace, according to a report on Thursday from a team of ...
Ice Sheets - Climate Change: Vital Signs of the Planet
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. Data from NASA's GRACE and GRACE Follow-On satellites show that the land ice sheets in both Antarctica (upper chart) and Greenland (lower chart) have been losing mass ...
Scientists drilled an ice core from Antarctica and were alarmed ... - CNN
2024年2月8日 · Evidence from a 2,000-foot-long ice core reveals that the West Antarctic Ice Sheet shrank suddenly and dramatically around 8,000 years ago, according to new research — providing an alarming...
Sea-level rise: West Antarctic ice shelf melt 'unavoidable' - BBC
2023年10月23日 · Increased melting of West Antarctica's ice shelves is "unavoidable" in the coming decades, a new study has warned. These floating tongues of ice extend from the main ice sheet into the...
Higher Antarctic ice sheet accumulation and surface melt rates …
2023年12月1日 · Antarctic ice sheet (AIS) mass loss is predominantly driven by increased solid ice discharge, but its variability is governed by surface processes. Snowfall fluctuations control the surface...
Unavoidable future increase in West Antarctic ice-shelf melting …
2023年10月23日 · Ocean-driven melting of floating ice-shelves in the Amundsen Sea is currently the main process controlling Antarctica’s contribution to sea-level rise. Using a regional ocean model, we present...
