The summer is over - and for about 16,600 people across 854 European cities that doesn't mean autumn comes, but death. People who would still be alive if it wasn't for our burning of fossil fuels. - New study with @lshtm.bsky.social www.imperial.ac.uk/grantham/pub...

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

Calling for EGU 2026 session proposals! If you have an idea for a geomorphology session, head to meetingorganizer.copernicus.org/EGU26/provis... and enter it in. Sessions on new topics and themes are extremely welcome! Help to build a great programme for EGU26!

🤩New paper from our team member @cchartierrescan.bsky.social entitled 'Snow drought propagation and its impacts on streamflow drought in the Alps' published on Environmental Research Letters! Big congrats! Check out more details here: iopscience.iop.org/article/10.1... #ClimateChange #Hydrology

Getting used to this image: #glaciers almost completely naked - unprotected by the white snow - in August... While July was good for glaciers after record-melt in June, the new heat wave again results in major ice loss @vaw-glaciology.bsky.social

#Satellites reveal early signs of slope instability: #SLF scientist Andrea Manconi shows that #radar monitoring with satellites help to detect slope instabilities like at Blatten years in advance. For details check the #ESA news article: eo4society.esa.int/2025/08/08/s... @esa.int @esaearth.esa.int

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...

Hunting the extreme year 2022... Yes, I'm really worried about the current state of Swiss #glaciers! After a dry winter, the scorching heat of the last weeks pushes glaciers towards another black year. Hoping for some cooling but the summer has only just started @vaw-glaciology.bsky.social

🌡️ Der #Permafrost in den Schweizer #Alpen war 2024 so warm wie noch nie – das zeigen die neuesten Daten des Beobachtungsnetzwerks #PERMOS. Diese Veränderungen werden sich auch in den kommenden Jahren und Jahrzehnten fortsetzen ➡️ scnat.ch/de/id/WbQd9 #Klima #Klimawandel

FAQ "Influence of #permafrost on #rockslopefailure": The permafrost in the Alps is warming rapidly and affecting major rock slope instabilities. Experts from the #SLF provide answers to the most important questions: www.slf.ch/en/permafros... 📷️ D. Hunziker #CERC #naturalhazards

[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/...

Wie genau kam es zum Gletscherabbruch, der zur bedauerlichen Verschüttung des Walliser Dorfes Blatten führte? Dieser Frage sind ETH-Forschende nachgegangen: ethz.ch/de/news-und-... #Blatten #Gletscher #Bergsturz #Birchgletscher

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/...

On 28 May 2025, the Birch Glacier in Switzerland catastrophically failed, generating a massive landslide that has partially buried Blatten. So what happens next? eos.org/thelandslide...

The major glacier collapse or rock-ice avalanche that was feared over the past few day occurred this afternoon in Lötschental, Switzerland. Our thoughts are with the local population and emergency responders as the we gain clarity on the dimensions of this event. #Lötschental #hazards #risk

In Switzerland, a major rock slope failure has developed, threatening the village of #Blatten, following a smaller landslide at the weekend. About 300 people have been evacuated. The mobile mass has a volume of up to 5 million cubic metres. eos.org/thelandslide...

🚨Acute rock avalanche danger above Blatten, Switzerland 🚨 Emergency management has ordered the evacuation of the village of Blatten because of a large destabilized rock mass on Klein Nesthorn 🏔️ The mass could impact Birchglacier, possibly amplifying mass and runout. www.bluewin.ch/en/news/swit...

New study shows: #Spring in mountains is starting earlier and earlier due to #climatechange. This affects #biodiversity, #agriculture and the ecological balance in the #mountains. #SLF biologist @mizeh.bsky.social used data from 25 years to achieve this. More: www.slf.ch/en/news/spri... 📷 M.

How can Switzerland prepare for extreme events and their effects that have never been seen before? This is the topic of the WSL research programme #Extremes and was the topic of the "Forum für Wissen 2025": www.wsl.ch/en/news/inve... @extremeswsl.bsky.social @wsl-dme.bsky.social #extremeevents

Tomorrow is the first International Day of #Glaciers! Let's not forget the suffering of these ambassadors of climate change. Let's preserve them, as far as still possible to limit the negative impacts on our environment. @scnat.ch @wmo-global.bsky.social @unesco.org

Der Schweizer #Wald steht unter #Druck: Hitze, #Trockenheit, #Stürme und Schadorganismen haben ihm stark zugesetzt. Der #Waldbericht von WSL und BAFU informiert alle zehn Jahre über den Zustand des Waldes und analysiert die Entwicklungen. www.wsl.ch/de/news/wald... #Waldbericht2025

Wir freuen uns auf den Anlass und an der Beteiligung am Beitrag des @slfdavos.bsky.social zu #Permafrost

Global warming causes extreme temperatures – this is clear to most, but few realize that both droughts and heavy rains are symptomatic of a climate in crisis. @soniaseneviratne.bsky.social explains the far-reaching impacts of climate extremes. ethz.ch/en/news-and-...

🗓️ 3 April 2025 | Save the date! The @wslresearch.bsky.social #Extremes Program will hold a Forum für Wissen, open to all. Join us in Birmensdorf, Switzerland to explore the state of research on future extreme events & discuss solutions developed with practitioners. ➡️ bit.ly/eXtremesForu...

The reactivation of the #landslide Ahörndler in Wattenwil (CH) began around one year ago. Movements of up to 1 metre/day have destroyed 60 hectares of forest, 4 residential buildings and 2.5 kilometres of roads. The volume of the landslide is estimated at approx. 5.0 million cubic metres.

Floods, debris flows, landslides, and rockfall events caused damage of around 75 million Swiss francs in 2023. This was the result of the annual evaluation of the storm damage database by the WSL. www.wsl.ch/en/news/stor... 📷Reto Thoeny

In Wattenwil hat sich infolge der Starkniederschläge von Ende 2023 eine permanente Rutschung massiv beschleunigt und eine Fläche von rund 50 ha erfasst. An Wald, Waldstrassen, Gewässerverbauungen und einzelnen Gebäuden gab es grosse Schäden.
