ONE YEAR of melting at Morteratsch Gl.! 😱 10 meters of ice thickness loss has been measured here at 2200 m asl! 🧊🔥 The massive cliff and the huge ice cave I was contemplating last October are gone... 😢 Webcam @vaw-glaciology.bsky.social

The last 5 years we entered an Era of extreme ice loss in the Alps! 🧊🔥 Over this period, 20% of initial ice volume has gone! 📈 This is evidenced here on Aletsch Gl. (2,900 m asl), a place where the ice shouldn’t melt to maintain glacier in balance! ⚖️ 📷 @matthias-huss.bsky.social

Perito Moreno (Patagonia, ARG) The front of this iconic glacier is now 910 m away from Península Magallanes, thus exceeding the ~750 m measured by German geologist Rudolf Hauthal in 1899! 🧊🔥 Area loss since 2018 amounts to 3.67 km²! 📈 Source: Glaciarium El Calafate

Devastating! 😱 The figures have just been published by glamos.ch Swiss glacier have lost 5.5% of their volume this year! (2nd worst year just after 2022)! Since 2022, 20% of total ice volume has gone! 📈 20%...in just FIVE years! 🧊🔥 Full report: doi.glamos.ch/pubs/annualr...

On 25th Sept., took place the biennial survey of Arcouzan Glacier (Mont Valier, Ariège) the most ‘special’ of the Pyrenean glaciers! 🧊💪 Despite all the heatwaves, it was still covered in firn, but amount of remaining ice and flow are limited 🌊🔥 📷 F. Laurens / H. Lucas hanslucas.com/flaurens/pho...

Fascinating glacial archaeology! 🏺🧊🧐 Around 158 CE, ~50 carefully crafted lanceolate stakes (of unknown use) were placed or left on or near the Forcle pass (2,543 m asl)! ⛏️ Use of the pass was not linked to variations in ice extent (LIA wood also found there) journals.openedition.org/gallia/9888

Joint fieldwork with the French 'Glacial Archaeology' team led by Eric Thirault allow us to sample subfossil trunks in Beaufortain massif! 🏔️🌲💍 Irony is that one of the trunk stood right in the middle of the path and had been trampled by generations of hikers, who had no idea how old it was! 😲⏳
