Incredible ice loss measured again at #Konkordiaplatz on the #Aletsch #Glacier, home to the thickest ice in the #Alps (still about 800 m!). Yesterday’s survey revealed another –4.6 m of ice gone in just one year. :( Measurements by @matthias-huss.bsky.social for GLAMOS

#IMC2025 is in full swing in #Innsbruck! You can meet us at several sessions throughout the week, looking forward to many inspiring science discussions!

Thanks to Gonzalo Gonzales de Diego for this week’s Glaciological Seminar on viscous contact problems, time-dependent flows where ice detaches/reattaches to bedrock. Key insights into subglacial cavities, grounding lines & numerical methods for modelling sliding and cavitation. 🧊💦

🎉 Congrats to our #VAW colleague & postdoc @landervt.bsky.social, on making HUMO’s 30 under 30 list alongside Remco Evenepoel & Jade Mintjens! 🌍❄️ A well-deserved honor for his scientific achievements. #30under30 #ScienceCommunication #glaciology #HUMO

Ever wondered what glaciologists actually do behind the scenes? 🧊⛏️ We’re launching The Glaciologist’s Logbook, short reels showing our day-to-day work. First up: ice thickness drilling on #Titlis glacier. 🎥 by Dominika Teluchova #VAW #Glaciology #Engelberg #Titlis #ScienceCommunication

#GLAMOS measurements have started last week with measurements on Rhone, Allalin, Corvatsch & Murtèl. Stay posted for the press release via @scnat.ch on 1st of October on the 2025 situation of #Swiss #glaciers.

Greetings from Marijn van der Meer at the #Ellis Summer School in Jena 🇩🇪! She presented her work on the #MassBalanceMachine. The school brings together AI & climate science & is co-organised by top institutes & supported by @climatechangeai.bsky.social, @esa.int Academy & more.

🌍 Even the most resilient glaciers aren’t safe. New research from our Austrian colleagues & contributions from #VAW member @marinkneib.bsky.social shows Central Asia’s glaciers may have hit a tipping point in 2018 after decades without data.

⛏️ How does mining-driven ice removal affect glacier evolution? In a new study led by #VAW colleague @landervt.bsky.social, we model 🇰🇬 Davydov Glacier (1850–2100), which lost huge ice volumes through a combination of mining & climate change. 👉 lnkd.in/eru5Xgur

That’s a wrap! This year's #Fieldcourse in Glaciology on #RhoneGlacier was a great success. Despite some tricky weather in the beginning, it turned out great. Huge thanks to all students and #VAW team members for their dedication and enthusiasm!

Congrats to #VAW member Aaron Cremona on successfully defending his PhD yesterday! 🎉 An excellent presentation, followed by an even tougher “exam” of yoga poses & Kovacs mounting, both passed with style. Well deserved, Aaron! 👏

On 28 Aug 2025, our new exhibition Deglaciation – Measuring the Ice opens at extract (ETH Zurich Collections & Archives). Join the vernissage at ETH Zurich, HG E7, 17:30 with remarks by Prof. Farinotti & team + apéro. 📍 ETH Zurich, HG E7 (Main Building) 🗓 28 Aug 2025, 17:30

Recent @glamos.bsky.social fieldwork on the #PlaineMorte glacier by @matthias-huss.bsky.social confirms what our models had already indicated: massive ice loss caused by the August heatwave in Switzerland. Even when expected, it is still striking, and sobering, to witness a glacier in its final days

1/3 🚨 Published today in @nature.com! We’re thrilled to celebrate the latest work by our colleague Dominik Gräff, with contributions from D. Farinotti & R. Moser 🎉 Using seafloor fiber-optic sensing, his team watched Greenland’s glaciers calve in real time & found something surprising 🌊🧊 📸: D. Gräff

Drone shots from last week’s fieldwork on Glacier de Tortin by #VAW's @beerjanosch.bsky.social. This low-elevation glacier is in bad shape, with >2 m surface melt last year. Englacial data indicates temperate conditions. #KeepSwissGlaciersCool #1400ReasonsToAct (Data: GLAMOS)

💧 Impressive meltwater flows at Pers Glacier! Postdoc @marit-vantiel.bsky.social and Leo Hösli recently carried out fieldwork at the #Pers #glacier, where they collected sensor data and performed tracer measurements to quantify discharge in the proglacial stream.

🧊 Deglaciation – surveying the ice New #exhibition @ethz.ch showcases 150 years of #glacier research: from ancient myths and early measurements to today’s #ClimateScience. 📅 29.08.2025 – 12.07.2026 👉 library.ethz.ch/en/news-and-... #glaciology #glaciers #zurich @vaw-glaciology.bsky.social

Two weeks ago, part of our team set up a network of 17 ablation stakes (plus 3 existing ones from GLAMOS) on Gries Glacier to measure surface melt. With such a dense network, we’re expecting to see strong spatial differences in mass balance across the glacier. ❄️📍📊

What an honor for our group head Daniel Farinotti to represent @swisspolar.bsky.social during a high-level visit to Australia & New Zealand! A key milestone: signing a Memorandum of Agreement with #AntarcticaNZ to strengthen polar science collaboration. 🇨🇭🤝🇳🇿

[1/4] New paper 📣 this study, led by PhD student @jane-walden.bsky.social, was recently published in NHESS: doi.org/10.5194/nhes....

An ice lamella collapsing at #Morteratsch #glacier over the weekend. ❄️ The footage serves as a reminder that while ice caves are breathtaking natural wonders, they are temporary by nature, and eventually destined to collapse. 🧊🫧 Entering them is always a risk.

The Swiss Cryosphere Report 2024 is out: Despite heavy snow, Swiss glaciers lost >2% of their volume. Permafrost hit record levels as heatwaves & Saharan dust take a toll on snow & ice. 🧊📉 #Kryosphärenbericht2024 #GLAMOS @slfdavos.bsky.social #PERMOS @scnat.ch 🖇️ cryosphere.scnat.ch/de/publicati...

A steep, overhanging ice cliff now marks the terminus of the #Morteratsch glacier. During yesterday’s field campaign, our #VAW team installed a new monitoring camera and measured stream temperatures. Striking to witness the glacier’s dramatic transformation firsthand.

What drives seasonal glacier mass balance in the Swiss Alps? A new preprint by #VAW PhD student Aaron Cremona (et al.) explores 2010–2024 trends using remote sensing, modeling & ML. 🇨🇭 Swiss glaciers lost an astonishing 25% of their 2010 ice volume! 🧊 📄 doi.org/10.5194/egus...

A VAW team was out on #Griesgletscher yesterday, a chance to raise awareness for the #1400ReasonsToAct challenge by @powswitzerland.bsky.social. Glaciers are in bad shape this year. Cooler conditions can’t come soon enough. Take action here: www.1400-reasons-to-act.ch #KeepSwissGlaciersCool

🚨 New paper alert! Glaciers in Western Canada, Switzerland & the conterminous US lost twice as much ice from 2021–2024 compared to the previous decade. Heatwaves + dust & wildfire impurities drove extreme melt. Co-authored by #VAW member @matthias-huss.bsky.social ❄️🌍

That’s a wrap! #WSL Research Day & our Mountain Hydrology & Mass Movements RU day in beautiful #Davos were inspiring. We are grateful to be part of such a vibrant research community. Big thanks to the organizers, esp. our RU head Dr. Manfred Stähli! @wslresearch.bsky.social @slfdavos.bsky.social

🧊 Welcome to Antoine Sévenier, our new MSc student! He will be working on englacial & subglacial melt quantification using repeat LiDAR, in collaboration with UNIL & EPFL. Yesterday, Antoine joined Marin to survey the #Morteratsch glacier cave, diving right into glaciology! 🏔️🛰️

From the Alps to Tien Shan, same story for the glaciers this year, on track for record losses! 🔥🥵 Little winter snow and already crazy heat! 32°C at 1100 m in Chamonix 16°C at 3600 m in Tien Shan Real time mass balance 👇 Swiss Alps @vaw-glaciology.bsky.social Bordu Gl. @landervt.bsky.social

The limited snow cover on Alpine glaciers is melting rapidly due to high temperatures. ❄️🔥 Bad news for the ice: without this protective layer, it loses both shielding and growth potential higher up. The difference with last year is striking. #climatechange #glaciers #Alps

What a unique honour: during yesterday’s visit of former #Federal #Councillor Adolf Ogi to the Lötschental, we shared our current understanding of the #Blatten ❤️‍🩹 event-cascade. We hope the importance of learning from this disaster to reduce future risks will be as clear to others as it was to him. 🙏

We’ve updated the #Birchgletscher factsheet – the 🇨🇭#glacier that collapsed on 28 May. It took just ~40s for the ice-rock avalanche to hit the valley equalling an average speed of ~200 km/h. New data on volumes & timing now included: polybox.ethz.ch/index.php/s/... #Blatten ❤️

[1/2] We’ve released a new version of the factsheet on #Birchgletscher -- the Swiss glacier that catastrophically collapsed on 28 May 2025 following heavy debris loading from Kleines Nesthorn -- and some first field impressions that we were able to collect yesterday 🗂 polybox.ethz.ch/index.php/s/...

Every +0.1°C of global warming leads to ~2% more glacier ice loss. Sticking to the #ParisAgreement (+1.5°C) would preserve over half the ice compared to current policies (+2.7°C). This is the result of a new study based, led by Harry Zekollari, Lilian Schuster & several co-authors from our group.

Here is a factsheet on what is currently known about Birchgletscher, the Swiss glacier that catastrophically collapsed on 28 May 2025, following heavy debris loading from Kleines Nesthorn. Our thoughts are with all those most deeply affected. polybox.ethz.ch/index.php/s/...

📣 We are hiring an Office Manager (80–100%) to support our internationally active research group. If you're highly organized, fluent in English and German, and looking to make a meaningful impact in science and society, we’d love to hear from you! 🔗 jobs.ethz.ch/job/view/JOP...

🚨Not all glacier meltwater makes it to the ocean 🌊 New paper co-authored by VAW Matthias Huss shows ~95% of future glacier runoff will flow to the sea via rivers, while 5% is lost to evaporation or stored on land. High Mountain Asia hold most of what doesn't reach the ocean. doi.org/10.1029/2025...

What a pleasure to be invited by @eth-eaps.bsky.social doctoral students to their annual retreat! The excursion to #Aletsch was a highlight, and seeing so many enthusiastic and engaged young researcher was a true boost in motivation! A format we recommend to every department at ETH and beyond

⚠️ New MSc project at VAW Glaciology! Explore how #glacier retreat under climate change could create future ice avalanche hotspots. Combine glacier models, avalanche inventories & terrain data to assess evolving risks. Apply now on this timely topic! tinyurl.com/ice-avalanch...

🚨Paper Alert! A new paper, co-authored by VAW Matthias Huss, shows glaciers worldwide have lost over 9,000 Gt of ice since 1976, raising sea levels by ~25 mm. 🌍 The paper presents a global dataset of annual glacier mass change from 1976–2024. Explore: 📊🧊 doi.org/10.5194/essd...

⛰️ This Monday, our grouphead Prof. D. Farinotti gave an insightful session on #glaciers in a changing climate, glacier instabilities, and water outbursts, deepened through interactive exercises for participants of the CAS #ETH Naturgefahren Risk Management course 🌍🧊 #Glaciology

Again a tough year ahead for Swiss glaciers? ❄️ Winter 2025 snow data from GLAMOS is in: a 13% snow deficit nationwide, but with big regional differences. A sharp contrast to 2024’s +31% surplus, yet even then, #glaciers still lost mass. Full results in the report 👇 doi.glamos.ch/pubs/winterr...

1/2 What happens when Antarctica’s hidden rivers meet the ocean? 🌊 Subglacial water beneath the ice can melt, reshape & destabilize ice shelves. A new @natgeosci.nature.com study by #VAW’s Huw Horgan & team shows how these flows influence West Antarctica. ❄️🧊 🔗 doi.org/10.1038/s415...

1/2 🚨 Paper Alert! Team member Ivan Utkin, former MSc student Ylu Chen, Ludovic Räss, and Mauro Werder have published a new study on glacier dynamics! 🏔️❄️ They present a #GPU-parallel inversion framework to reconstruct basal sliding coefficients using automatic differentiation.

🆕🇨🇭 For the first time ever, #GLAMOS publishes the Swiss Glacier Bulletin, a comprehensive look at glacier change in 2024. Despite heavy winter snow, 2.3% of ice volume was lost. A landmark report on a critical year for Swiss glaciers: doi.glamos.ch/pubs/glbulle... @matthias-huss.bsky.social

Many thanks to today’s seminar speaker @unibe.ch's Alexander Groos for a fascinating talk on Ethiopia’s glacial past, uncovering the Bale Mountain's icy history and how early settlers braved these high-altitude, periglacial landscapes. ❄️⛰️ #Palaeoglaciology
