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. ⬇️

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! Map of this region: zacklabe.files.wordpress.com/2022/08/b203...

A 3D animation from our last paper. We compared GPR ice thickness data with modelling approaches in two polythermal glaciers in W-Greenland. Check it out: www.cambridge.org/core/journal... 3D Data: Pléiades © CNES 2019, Distribution Airbus D&S

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. Data from NOAA OISSTv2.1. For more info arctic.noaa.gov/report-card/...

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. Read it here: www.cambridge.org/core/journal...

What remains of the former Fradusta Glacier (Pale di San Martino), in the Italian Dolomites. Photos from Sept. 5, 2025

A few snapshots of Travignolo #Glacier on Sept. 4, 2025. A small glacier nested in the Italian #Dolomites (Pale di San Martino).

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! ... Otherworldly! 🪐 www.pnas.org/doi/10.1073/...

Canin East Ice Patch in the Italian Julian Alps and the AWS nearby, managed by the Alpine-Adriatic Meteorological Society. Photo from last friday (Aug 8)

Epic views from last Wednesday fieldwork in the Dolomites, close to Cima D'Uomo.

Possibly the most unreachable webcam of the Julian Alps, monitoring the Canin East ice patch #enlapse #julianalps #timelapse #cryosphere

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! 🌊 📷 D. Farinotti - @vaw-glaciology.bsky.social

Already + 100,000 m3 fallen from the Klein Nesthorn N face at ~3200 m asl, and something between 1 to 5 Millions m3 more are 'forecasted'... 😱 That's quite a thing! Blatten village evacuated 😭 The 'Crumblocene' is definitely a nice time to live! 🏔️🌊 www.20min.ch/fr/story/can...

This is horrible. I don't even know what to say. Some of our most key polar data. "As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported." nsidc.org/data/user-re...

The Warming Stripes have now been extended downwards into the ocean and upwards into the stratosphere! Collaborative paper which tells the story of how the stripes were developed, and discusses their extension across the Earth system, is now available in BAMS: journals.ametsoc.org/view/journal...

It's so sad to see that this incredible dataset, which has redefined how we approach many Arctic-related studies, may not be updated in the future 😞

I finally tried Gaussian Splatting using some handheld photos taken inside an ice cave. In just 10 minutes of training-rendering, the results were stunning, impressive! 😁 For now only for visual purposes... #gaussiansplatting #icecave #digitaltwin

Sad news (but great work) from the Austrian Alps tc.copernicus.org/articles/19/...

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. Paper: tc.copernicus.org/articles/19/...

Pisgana West (Adamello, IT) 1990 | 2021 Remember the 1990s? ⌚️❄️ Seems so far away from a glaciological point of view! 😱 And the most recent pic here was taken before the recent record-breaking heatwaves which wiped out 10% of Alpine ice in just 2 years! 🔥 📷 Servizio Glaciologico Lombardo

The Glacier Mass Balance Intercomparison Exercise is out! Herculean effort bringing together >200 estimates of glacier loss outside the ice sheets. Bottom line is 273 gigatonnes per year of ice loss since the year 2000! 😲 Open-access article: doi.org/10.1038/s415... 🥼❄️ @natureportfolio.nature.com

So nice to see such high resolution data from @legertancrede.bsky.social LGM modelling. Including the smaller local glaciers (red square) of the Venetian Prealps in Lessinia, Carega, Pasubio, Asiago Plateau and Monte Grappa 😍 Paper: www.nature.com/articles/s41... Videos: doi.org/10.5281/zeno...
