Unterwegs in Blatten. Ein Portrait über mich, die Liebe zu den Bergen, den Umgang mit Risiken, und die Überzeugung, dass positive Narrative, Lösungen und ein politischer Rahmen zwingend sind.

Mehr Strom im Sommer – aus Photovoltaik, nicht Wasserkraft.

Remember the catastrophic rock-ice avalanche of Blatten 🇨🇭 this May?
This incredible image comparison shows like nothing else the darkening of mountain peaks.
And along with the disappearance of snow, ice and permafrost, new hazards come along

Like pulling the plug of a bathtub: an incredible mass of #glacier ice disappearing at Griesgletscher (🇨🇭/🇮🇹) in one century.
It felt emotional to visit the exact same spot @swisstopo cartographers chose in 1919. The view was so different.
Simply unbelievable!!

🏔️ Switzerland is losing its glaciers - fast. 2025 alone saw a dramatic 3% loss, making it the fourth-worst year on record, according to @matthias-huss.bsky.social (GLAMOS & @vaw-glaciology.bsky.social) and @scnat.ch. Learn more here 👉 scnat.ch/en/id/wLLYv

🏔️ Die Schweizer Gletscher schmelzen weiter. 2025 haben sie rund 3% ihres Eisvolumens verloren – der viertgrösste Schwund seit Messbeginn. Das berichten @matthias-huss.bsky.social (GLAMOS & @vaw-glaciology.bsky.social) und @scnat.ch. Mehr dazu 👉 scnat.ch/de/id/wLLYv

110 years ago, glaciologists climbed up to Claridenfirn 🇨🇭 to start the longest measurements of #glacier mass balance worldwide.
Yesterday morning, the scene looked so different! Still beautiful, but the ice got slim... Almost sentimental to see another crazy year up there

One more year: Ice loss at Konkordiaplatz on Aletsch #Glacier is just... wow 😲 Minus 4.6 metres of ice.
Will there ever be a call:
"Make Aletsch Great Again"?
It would be about time

The #Glacier Loss Day is reached in Switzerland!
From now on all melt that occurs on glaciers until October is unsustainable. This tipping point has only been reached so early in the record-shattering year 2022.
Expect big ice loss due to the prolonged melt season and feedback effects

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

The tongue of Rhone #Glacier ten days after my last visit. Can you guess how much ice melted away? 1️⃣ meter in terms of thickness! 1️⃣0️⃣ days... And that's just the beginning of the summer season.
We know the times are bad for the ice, but still it is hard to accept these numbers!

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 👇

The first Swiss Glacier Bulletin summarising our monitoring activities on #glaciers throughout 🇨🇭 in 2024 has just been released!
(GLAMOS)
The documents provides an overview about all observed variables and points out exceptional events. Read more here:

Winter #snow measurements on #glaciers for 2025 in the frame of GLAMOS are completed. Read our report on the results 👇
There's a 13% glacier snow deficit Swiss-wide, with strong spatial variability though. Another difficult year for glaciers ahead...

The snout of Findel #Glacier, Zermatt, on 4 April 2025. 2600masl, snow depth: zero.
It is incredible, we're seeing the third winter #drought in four years...
The delicate crevasse situation is an additional challenge to our GLAMOS measurements...

What a beautiful morning captured by our webcam on Silvretta #Glacier today. Shiny fresh snow, but it is very little compared to the average for this time of the year...
