A New study by Léon Russel et al. (with #VAW member Marin Kneib) shows Saharan dust boosted melt on Argentière Glacier 🇫🇷 by ~10%, and up to 13% in 2022. Desert dust darkens the ice, lowers albedo, and can thereby accelerate glacier loss. ❄️

[1/2] 📢 GLAMOS @scnat.ch press release out today: Swiss glaciers lost another 3% of their volume in 2025, the 4th-largest decline ever measured. In just 10 years, they’ve lost a quarter of their ice mass. Over 1k small glaciers have already vanished.

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.

⛏️ 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

Landslide activation during deglaciation in a fjord-dominated landscape: observations from southern Alaska (1984–2022)
Abstract. A consequence of the current global glacier mass loss is the destabilization of valley walls as the support provided by the glacier evolves and eventually vanishes. In this work, we examined...

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 ❤️

Mixed feelings on this #bluebird #day below Weissmies on #Hohlaubgletscher. Measured snow depths as low as 1m on a high alpine glacier at the very end of the winter. Tough times ahead for Swiss Glaciers. 💦🧊

That’s a wrap ❗️Had some really great three days in Oslo attending the Global Glacier Modelling Workshop. ❄️🇳🇴 Hope this format will be kept alive in the future.
Greetings from sunny, winter-cold Oslo and the Global Glacier Modelling Workshop 2025! ❄️ Several #VAW members joined to present exciting new developments on the Global Glacier Evolution Model as well as the Mass Balance Machine. Three productive days of great discussions! 💻🇳🇴

Spend a productive Hackathon week at #EPFL Sion. Looking forward to future developments on the Global Glacier Evolution Model #GloGEM. 👨💻❄️🤖
Part of our team spend the last week at a #GloGEM hackathon in Sion! 🎉 Goal: create a public version of the Global Glacier Evolution Model, prepare docs/manuals, and discuss future plans. Of course, there’s also time for Swiss cuisine! 🇨🇭🫕 Excited to see their results soon! ❄️

One of the most thrilling climbs Domča and I have done! The limestone cliffs here in Railey, Thailand are packed with insane overhangs and stalactites, a pure paradise for rock climbing.
Also, the sweatiest spot ever! Climb early or late to beat the heat. 🥵☀️

Ever seen a robot nosedive into a glacier moulin? 🧊🤖 Last week, VAW’s @MarinKneib & Max Polzin ( @EPFL robotics) deployed a LiDAR-equipped robot on Zmutt Glacier to map englacial conduits in 3D. A possible game-changer for exploring inaccessible glacier interiors!

Final Stop of this summer's field campaign: Alphubel South Face. 🏔 This tiny, high-altitude glacier, tucked into the south face of #alphubel, caught our eye on the map. Its steep incline and south-facing exposure make it vulnerable to summer melt despite the high elevation.
