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.

Jan 18, 2024 · Greenland's ice sheet loses about 193 square kilometers of ice per year, researchers found. Study co-author Chad Greene and his colleagues said they qualified the extent of calving, which...

Feb 13, 2024 · An estimated 11,000 sq miles or 28,707 sq kilometers of Greenland's ice sheet and glaciers have melted over the last three decades, according to a major analysis of historic satellite records.

1 day ago · Melting causes the Greenland Ice Sheet's glaciers to flow faster down slopes and valleys; this, in turn, stretches the ice sheet so much that it cracks open, Chudley explained.

Dec 21, 2024 · A disturbing new video shows 13 years of melt at the Greenland Ice Sheet. The video was stitched together based on NASA and European Space Agency (ESA) satellite data.

Aug 14, 2024 · While snowfall in June and July covered dark bare ice areas on the ice sheet's margins, a heat wave in early July exposed this ice in western Greenland, increasing melt in that region. Temperatures so far this summer have been near the 1991 to 2021 average.

4 days ago · The Greenland Ice Sheet is cracking open at an accelerating pace, with crevasses growing larger and deeper due to the effects of climate change. A new study using high-resolution 3D mapping has revealed that fractures at the ice sheet’s fast-moving edges have expanded significantly in just five y ... So if ice melts at the surface and runs ...

The Greenland Ice Sheet lost 55 ± 35 Gt of mass in 2024, the lowest annual ice loss since 2013. This occurred due to above-average snowfall and below-average melting and despite higher glacier flow rates than the 1991-2020 average.

On 26 June 2023, Summit Station reached a temperature of 0.4°C and experienced melt for only the fifth time in its 34-year observational history. The Greenland Ice Sheet (GrIS) is the second-largest contributor of sea-level rise (SLR), after thermal expansion (Zemp et al. 2019).

Jan 17, 2024 · Icebergs have tumbled from Greenland’s glaciers for thousands of years as part of a natural cycle that typically balanced glacier growth in the winter with melting and retreat in the summer. The new study finds that ice retreat has far outpaced growth throughout the …
