@subfossilguy Amazing here:)

When the dust will clear up...💨 Preparation of Morteratsch Glacier samples (Little Ice age, 1st two), Fee Glacier (Roman Period) and Mer de Glace (Bronze Age) today! 🤩🌲💍

From early next week, however, a marked cooling is expected, with snowfall from around 3,800 m. This could (largely) bring the melt season to a halt.

This is driven by persistently high temperatures and a lack of snowfall in the Central Tien Shan. Satellite imagery confirms it: on many glaciers, there is no accumulation area left at all.

Unprecedented mass loss on the Tien Shan glaciers this year – will the Bordu Glacier drop below -2.5 m w.e.? Our mass balance model is still showing an exceptionally high rate of loss for this time of year.

The 𝗗𝗮𝘃𝘆𝗱𝗼𝘃 𝗚𝗹𝗮𝗰𝗶𝗲𝗿 is more than ice, it’s a case study of how human activity + climate shape our future. Curious? Dive into our full study agupubs.onlinelibrary.wiley.com/doi/10.1029/20… Or reach out, happy to discuss!

What we studied: With our 3D glacier model, we tested: 🔹 Past & present impact of mining 🔹 Future retreat if mining stops 🔹 How long until mine shafts flood without pumping 🔹 Hypothetical regrowth if we returned to 1850 climate

📢 𝗡𝗲𝘄 𝗣𝗮𝗽𝗲𝗿! ❄️🇰🇬 We modeled the #𝗗𝗮𝘃𝘆𝗱𝗼𝘃 𝗚𝗹𝗮𝗰𝗶𝗲𝗿 (1850–2100) in #Kyrgyzstan. Not just another glacier (>200,000 exist worldwide) — this one is special. 👉 Why? Stay tuned. 👉 Full paper: agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

@david_belay @LanderVanTricht These ones are taken by a DJI Phantom 4 RTK :)

@LanderVanTricht May I ask how those pictures were shot? if they are drone pictures, what equipment was used? I am myself trying to photograph glaciers in the Alps but I am frustrated by the quality difference between a consumer drone like the Mavic and a regular non-flying camera.

🚨 Update uit #Kirgizië. Ons model toont dit jaar record gletsjermassa-verlies (en het smeltseizoen is nog niet voorbij). Oorzaken: weinig sneeuw🌨️, hoge temperaturen🌡️, amper zomersneeuw❄️. Ons veldwerk bevestigde dat er zelfs op de top van sommige gletsjers géén sneeuw meer lag

🚨 Abstract submission deadline for #EGU25 is approaching! 🚨 🌍❄️Our session welcomes research on glacier changes, past, present & future, using field data, remote sensing & modelling 🏔️ Join us & share your latest insights! 🔗 Submit here: meetingorganizer.copernicus.org/EGU25/session/…

Very little snow at the moment in the Central #TienShan (Kyrgyzstan). Mass balance is very low for the time of the year at #Bordu glacier. However, mass balance is mainly dependent on what happens between April and August.

📢 Excited to share our #EGU25 session CR1.1: "Glaciers & Ice Caps under Climate Change" 🌍❄️! Join us in Vienna (27 Apr–2 May 2025) to explore glacier changes via fieldwork, remote sensing, & modelling. 📝 Abstracts due: 15 Jan 2025 🔗 Submit here: meetingorganizer.copernicus.org/EGU25/session/…

The front of the #Morteratsch #glacier has changed dramatically over the past 2 years. On the left, a glacier cave (glacial portal) has formed where a subglacial river emerges. Notice also the massive cliff in the central part, where the front is aligned with a former #moulin.

Final temperature and precipitation data are in. The mass balance season of 2023/24 ended for #Bordu #glacier in #Kyrgyzstan with a record negative value of -1.66 m w.e. The glacier is representative for the Central #TienShan mountains.

First day on Pers glacier today. The ice is falling apart, right in front of our eyes. Again strong melt this year.

Warm days late in September have caused some additional melt for glaciers in #Kyrgyzstan. This means we are still not at the minimum for the 2023/24 balance year (that ends 30 September). Strong cooling is expected from 28th September onwards according to weather forecasts.

Glacier mass balance measurements on #Claridenfirn today. Beautifull arctic conditions with 30 cm of (fresh) snow. But (again) a large ice loss unfortunately last year.

Konkordia ice loss (Aletsch Glacier) 2022 | 2023 | 2024 Thickness loss at the thickest ice in the Alps! 🔥 Last two years were record breaking... 🌡️ What do you think of the protective effect of the thickest snowpack in 25 years? 😅 Data/pic @matthias_huss @glamos_ch

Projection based on last 6 years however shows some more loss (but in general without snow cover). On-site measurements will soon confirm if 2023/24 is indeed a record negative year for the glaciers.

Central Tien Shan experienced a major snowfall event yesterday, with 11 cm of snow recorded at the Kumtor Gold Mine. This likely brought the glacier melt season to an early end, with our real-time model showing a record low mean specific mass balance of -1.62 m w.e.
