Glaciers Are Warming More Slowly Than Expected, but Not for Long - Eos An unprecedented dataset offers insight into the counterintuitive cooling effect of glaciers on a global scale.

As glaciers shrink in size, they will no longer be able to generate katabatic winds, and their rate of warming will begin to reflect ambient temperatures.

Hybrid Glacio‐Hydrological Modeling Reveals Contrasting Runoff Changes in Western Patagonia Over the 21st Century Hybrid glacio-hydrological models outperformed traditional approaches in predicting streamflow in ungauged basins and areas The regional freshwater flux was 19,815 m3 s−1 (2000–2019), with glacie...

🚨 New study alert! Our research reveals contrasting water futures for Western Patagonia under climate change. Some areas could face severe shortages, while others may see increased flows. 🏔️💧 #ClimateChange #Patagonia #Glaciers

Many congratulations to the amazing @frediotto.bsky.social for receiving the Hans Oeschger Medal! This career award from the @egu.eu Climate Division underlines the ground-breaking research Fredi did on many fronts, most notably on near-realtime extreme event attribution @wwattribution.bsky.social

Damage development on Antarctic ice shelves sensitive to climate warming - Nature Climate Change Damages such as crevasses or cracks can be early indicators of ice shelf weakening. Here, the authors quantify changes in damage structures in Antarctic ice sheets, which show sensitivity to warming

🚨 New paper alert!

Research by postdoc Maaike Izeboud from the bglacier group in Nature Climate Change 🎉

Using 20 years of satellite data, she mapped Antarctic ice shelf fractures and showed how damage rises under high emissions but stabilises in low-emission futures

Damage development on Antarctic ice shelves sensitive to climate warming - Nature Climate Change Damages such as crevasses or cracks can be early indicators of ice shelf weakening. Here, the authors quantify changes in damage structures in Antarctic ice sheets, which show sensitivity to warming

24 years of satellite data reveal a dynamic, cyclic pattern of ice shelf damage across Antarctica.

Damage, linked to flow acceleration, strain, and thinning, shows strong sensitivity to climate warming, suggesting current models may underestimate future retreat.

Op deze dag waarop belgische universiteiten protesteren tegen de kille besparingen op hoger onderwijs en wetenschappelijk onderzoek, komt deze boodschap van het Nobelprijscommité duidelijk binnen.

Please join USAA-IPCC and @agu.org next week for a webinar on how to engage with @ipcc.bsky.social reports as an Expert Reviewer! The Special Report on Cities and Climate Change opens for first review on Oct 17 - we'll discuss in our webinar how to register and what makes for good review comments.

IJsgrotten: de plek om gletsjers van binnenuit te bestuderen, maar ook een teken van een stervende gletsjer. ❄️

Tijdens veldwerk op de #Morteratsch en #Pers gletsjer ontdekten we meerdere ijsgrotten: natuurlijke tunnels gevormd door smeltwater dat het ijs van binnenuit uitholt.

Very happy to start my FWO-funded postdoctoral fellowship today, working with @harryzeko.bsky.social , Jordi Bolibar, and @marit-vantiel.bsky.social. Our project will explore how glaciers buffer streamflow droughts worldwide 🌊🌍 and how this role may change under what-if scenarios🔥🧊.

Excited to be back on the #Morteratsch #glacier complex for our annual fieldwork. Together with colleagues from the Geography department, the coming week we will measure how the glacier is changing. Stay tuned for some updates!

Over the last decade, glaciers in the European Alps have lost more than 15% of their area.

New study by Codruț-Andrei Diaconu, introducing automated tool to map and quantify glacier area changes (+uncertainties)!

Update on this thread: Thanks to the feedback on this thread, I realized the methodological problems with the Voortman and De Vos (2025) paper (which the New York Post heralded as "Rising-sea hysteria debunked") went deeper than I originally realized, and clearly necessitate retraction. 1/

🚨 Update from #Kyrgyzstan. Our mass balance model shows record glacier mass loss this year (and the melt season isn’t over yet). Causes: little snow 🌨️, high temperatures 🌡️, hardly any summer snowfall ❄️. Our fieldwork confirmed: even at the summit of some glaciers (#Grigoriev), no snow remained.

La fonte des glaciers impactera jusqu’à la Belgique Bonne nouvelle : on peut encore sauver une grande partie des glaciers. Si le réchauffement climatique est limité à 1,5 °C par rapport aux valeurs préindustrielles, comme le prévoit l’accord de Paris, il est possible de préserver plus de la moitié de la masse des glaciers dans le monde. En revanche, si l’on reste sur la trajectoire empruntée par les politiques climatiques actuelles et menant à environ 2,7 °C de réchauffement, seul un peu plus d’un quart subsistera. C’est l’une des conclusions d’une très vaste étude, menée par une équipe internationale de 25 chercheurs s’appuyant sur l’utilisation de pas moins de huit modèles différents. Ce qui rend cette étude particulièrement remarquable, c’est qu’elle s’intéresse à l’évolution des glaciers sur le long terme.
