In early July 2023, a series of rapid mass movements were triggered by extreme precipitation (and snowmelt) carried by an atmospheric river in Qeqertarsuaq (Disko Island), West Greenland.

In our last work, published today, we briefly analyzed the event, read the paper here: lnkd.in/gA_T4d2H

#CopernicusClimate has released its first data from the Copernicus pan-Arctic Regional Reanalysis (CARRA2): 2.5 km pan‑Arctic coverage, 24 years of data in the Climate Data Store, more realistic physics & improved details for local extremes, lots of added details with respect to ERA5.

Line graph time series of 2025's daily Arctic sea ice extent compared to each year from 1979 to 2024 as shown with thin lines in colors from purple to white. There is large daily variability, but a long-term decreasing trend during all months of the year. A seasonal cycle is also visible in this region.

Ice-free conditions continue in the Barents Sea region of the #Arctic Ocean. This is one area that has observed some of the largest losses of ice over the last few decades... compare the older years (dark/purple lines) to today!

Polar stereographic map of sea surface temperature trends for Septembers from 1979 to 2024. Red shading is shown for warming trends, and blue shading is shown for cooling trends. All areas of the ocean are observing warming.

Sea surface temperatures are warming across the entire periphery of the #Arctic Ocean in September.

This is especially observed in areas with long-term declines in sea ice concentration, such around the Chukchi and Kara Seas.

Our new paper compares GPR ice thickness data with models and looks at glacier thermal structures in Greenland, showing that thermal complexity (warm-cold ice) inside these glaciers is higher than expected.

2024 glacier loss in Svalbard was beyond imagination! 😱

- Anomaly of up to 4 SD!
- Amounts to ~61.7 Gt => 1% of the total ice volume
- Comparable to that of the Greenland ice sheet (55 Gt), which is 50 x larger!

Close up heli view of the former Klein Nesthorn ridge yesterday! 🚁😲

The summit ridge has lost more than 100 m in elevation and its north face ~130 m! 😱

All this mass ended up on the glacier, causing it to break up! 🌊

Effective May 5, 2025, NOAA’s National Centers for Environmental Information (NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (COGS). As a result, the level of services for affected products below will be reduced to Basicβ€”meaning they will remain accessible but may not be actively maintained, updated, or fully supported. This includes Sea Ice Index, Snow Data Assimilation System (SNODAS) Data Products, Glacier Photograph Collection, U.S. National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format Gridded Monthly Sea Ice Extent and Concentration, 1850 Onward World Glacier Inventory. If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.

Check out our latest work from the Dolomites. We tried to estimate the mass balance of the remaining Dolomites glaciers since the 1980s using LiDAR, SfM and historical imagery. No surprise: huge mass loss, shrinking area, and increasing debris cover.
