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

2001 is the only (isolated and weak) positive mass balance year of the 21st century! The negative trend lasts since the mid 1980s...

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...

Switzerland's glacier report 2026 is out. Swiss glaciers have lost 5% of their ice volume this year. Only the last 5 years accounted for nearly 20% of the total ice loss across Switzerland. The numbers are devastating. Full report → doi.glamos.ch/pubs/annualr...

Nope. Apparently, the poles were not used for that. 'The care taken in the finish of the lanceolate-tipped wooden elements of the Forcle could suggest that it was used for ritual purposes'

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
