BEFORE/AFTER Ghizer GLOF! 🌊. The lake that drained last night and triggered the flood and cascade event (and a new lake in trunk valley) is the highest of a series of three lakes, the only 'ice-contact' lake, but not the largest! 😲. Via Sher Muhammad 🙏

The magnitude of glacial collapse in the Alps is hard to grasp! 😲. Remember Sept 2022 when Tsanfleuron Pass was first ice-freed?.Now it looks like this. 😱. And for context, there was at this location in 2008 at least 35m ice thickness connecting the 2 parts! 🧊. 🎥Harsh Beria

This is what the Yakhar Glacier, located on the eastern face of Damavand (5,610 m asl), Iran's highest mountain, looks like this summer! 🔥💧🌊. There are today less than 27 km² of glaciers in Iran (RGI 2017). 🎥saeid salehi nandal

2022 summer was the worst on record for glacier loss! 🔥😱. It foreshadows what summers will be like from now on, as 2025 looks almost similar. 😭. Here is a 9-months timelapse of Mer de Glace (Dec. 2021-Sept. 2022) ending with those terrible melt rates. 🎥laplaceduvillagetv

Extractivism is such a wonderful (addiction) thing! 🤪. It can move mountains (there are plenty of examples), but now also churches! 🤮. If only we used our intelligence in the right way. .
An iconic 113-year-old church was carefully driven through the streets of Sweden's northernmost city, marking a poignant moment in a decades-long effort to relocate the city of Kiruna due to mining activity

I JUST CAN'T BELIEVE MY EYES! 😱. On 15 Aug. at Lac de la Muzelle (2105 m) in the heart of the Écrins NP, 215 tents were pitched for bivi! . Surveys conducted by the NP reveal high proportion of mountain novices, attracted here by Instagram, TikTok or even AI recommendations!.1/

Endless debris flows. 😱. These images of the debris flow that hit Bionaz (1600m, Valpelline) last night show why you should avoid rivers and streams during heavy thunderstorms in the mountains! 🌊. 🎥Meteo Valle d'Aosta.Via @Alpenweerman
