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. :(

🤩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...

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

#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.

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

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

🌡️ 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

[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

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.

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

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

Webcam image of the deforming slope at Blatten in Switzerland.
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.

🚨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.

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.

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

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.
