Tré-la-Tête Glacier 1990s | 2025 Demise of the most 'secret' (fact already emphasised by Whymper in 1909!) large glacier of the Mont Blanc massif! 🏔️ 🧊 The icefall no longer exists and most of the left tributaries have broken off! 🔥 📷 Cesare Balbis and Lauriane Miara

Imagine Tré-la-Tête Gacier in the 'Swinging Thirties' when first glaciological work began there! 🧊⏳⛏️ So moving to see these beautifully dressed early glaciologists! 🎩 No Gore-Tex, but gender balance! 🤍⚖️ 📷 Claudius Bernard

Want to acquire such a priceless piece of our natural heritage? 🥰 This is a subfossil spruce from late Roman period that comes from Bossons Glacier in Chamonix! 🌲⌛ What makes it special? 💚 - Spruce is pretty rare in moraines - Precisely dated to early summer 253 CE! wemakeit.com/projects/gla...

4°C at Observatoire Vallot (4365 m asl) on Mont Blanc on the 19th Sept. ! 🔥😱 This was unbelievable in full summer few decades ago, now this occurred regularly outside summer! 📈🥵 Data: IGE meteo station via X. Cailhol

Tour Glacier this morning! 🥰🧊 The contrasts of autumn are the best! 😍 Chardonnet and Aiguille Verte overlook snow-free ice bodies 🔥 📷 @lomdumtblanc.bsky.social

Glacier subfossil wood cookie of the day! 🥰🌲💍 Argentière Glacier lateral moraine Oct. 2024! 🧊 Don't miss a unique opportunity to acquire one of those exceptional samples, by helping science to find the last ones before it is too late...! ⌛🔥 wemakeit.com/projects/gla...

📣📣 Call For Donations! 💰💰 I am raising funds to finance the 2025 'glacier subfossil wood' field campaign! Do you want to continue hearing tales about glaciers and trees? 🧊🌲💍 I need your help! 🤍 To learn more: wemakeit.com/projects/gla... 🙏🙏 Please share it widely! 🙏🙏

Bossons Glacier 2022 | 2025 These 3 years show the most impressive glacier collapse ever! 🧊😱 The Mont Blanc massif and Chamonix icescape will never be the same... 🔥😭 Glaciers are now completely out of context with the climate zone in which they are located! 🌡️📈 📷 MeteoValledAosta

Argentière Glacier 2014 | 2025 Worst decade ever for Alpine glaciers! 🔥 2014 was the last year in which some positive mass balances were recorded in the Alps, as you can see from nice snowpack at the end of July! (Dates: 24th July vs 9th August) 🙏 @lomdumtblanc.bsky.social for 2025 pic

Glacier du Mont Ruan.

The striking spectacle of the ice revealing itself when the mist finally lifts, unexpectedly! 🌥️ Those thousands of sparkling crevasses 🧊 That vivid sensation of flow! 🌊 Marks your entire life. ~ Saleinaz, 16 years ago, exactly ~

Mont Blanc (4806 m) and Dôme du Goûter (4304 m) from La Jonction (2589 m) this morning! 🥰 This place which used to be an immersion in the 'glacier realm' accessible from a hiking path is less and less 'icy'... 🧊🔥 📷 @ABettmeralp

Mont Blanc from Col de Balme Last night | c. 1810 Surely one of the best Mont Blanc profile! ⛰️ Which will soon be missing its long icy tongue stretching towards the valley... 🧊👅 📷🖌️ @chesnel.bsky.social and Jean-Antoine Linck 🙏

2022 was the most detrimental summer for glacier loss ever! 🔥😱 It foreshadows what our 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 Via laplaceduvillagetv

51th heatwave in France since 1945, and second one this summer...! 🥵 Likely one of the most detrimental summer ever for glaciers! 🧊🔥 Mer de Glace is losing more than 10 cm/day during this Aug. heatwave! That's...just...INSANE!😱 www.franceinfo.fr/environnemen... 📷 Webcam Mer de Glace today

Ice thickness loss at this place on Mer de Glace exceeds 10 cm per day since the August heatwave began! 🔥 📈 Since May, the cumulative loss is around 8 meters!

Constant rockfalls on north face of Col du Plan today! 😱 🎥 Philippe Batoux

Large rockfalls at the moment in the north face of Aiguille du Goûter (3863 m)! 😰 Iso 0°C at 5100 m today! 🥵 📷 @lomdumtblanc.bsky.social

Mer de Glace has lost 4.5 m in thickness at the level of the ice cave (1750 m) since the 1st May 2025! 😲😱 On 5th July, it has been recorded 5 cm of ablation in 5 hours... 🔥 Ablation rates are truly absurd now in the Alps! 🥵 Source/pics: Pierre Jeanneret & Luc Moreau

Tré-la-Tête Glacier 2009 | 2025 Glacier collapse in the Alps is so rapid that it is leaving behind glacier tongues that have been cut into several pieces 🧊🔥 See what the former front of one of the largest glaciers of the Mont Blanc Massif now looks like! 😰 2025: www.instagram.com/p/DMdMF5Es9b...

Mont Blanc from Chamonix this morning! 😍 Almost 4 km vertical distance! 🏔️ This seemingly unchanging glacial landscape has recently undergone huge changes due to record-breaking ice melt of recent summers (2022/23/25) 🔥 Never thought I'd witness such a rapid collapse! 📷 @lomdumtblanc.bsky.social
