This could be one of the first documented timelapse photography of a surging glacier ! This movie shows the snout of Variegated Glacier in Alaska. This glacier is about 20 km length. The glacier surged over about 2 yrs, in 1982-1983. It is known to surge every 16-26 years youtu.be/GXbztmkmeSs?...

A massive Alaska landslide in 2025 triggered a tsunami wave that surged 1,580 feet up fjord walls — one of the highest ever recorded.
Alaska’s near-record landslide tsunami sent a wave 1,580 feet up the fjord walls – and left clues for building a warning system
The tsunami struck just 12 hours after a cruise ship had left the fjord, rattling the tourism industry.

Superb aerial footage of Zanskar mountains (Ladakh, India)! 🤩 The accumulation area of the mighty Drang Drung glacier (largest gl. in Zanskar with ~70 km²) is visible at foreground 🧊 Nun-Kun massif (7,135 m) in the distance! 🏔️🏔️ Nanga Parbat (8,126 m) on the horizon! Via @Kyangs_Thang 🙏
We all know how important glaciers are for us. Can we preserve these beautiful landscapes? I hope for a better future and my mission to study, document and preserve them continues. Happy World Glacier Day ❄️ Gaisbergferner Photo credit: Risch-Lau Collection, Vorarlberg #Glaciers #ClimateChange
The new glacier inventory for the Hindu Kush Himalaya maps over 63,700 glaciers, one of the planet’s largest freshwater reserves. It reveals that these glaciers are shrinking under accelerating climate stress.

Cryospheric geomorphology is amazing! 😍 Here is a massive and delicately carved Neoglacial moraine (Réou d'Arsine Gl.), the lower part of which has evolved into a magnificent rock glacier with concentric lobes 🧊🌊 The whole being heavily laden with snow, even on the steepest sections! ❄️

With emissions still rising 📈 and the catastrophic consequences 🔥 becoming ever clearer, geoengineering is getting ever more tempting 🧪 But a review has concluded that the main methods proposed to save polar ice 🧊 are not doable or won't work www.newscientist.com/article/2495...
Geoengineering is not going to save the poles from climate change
A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both

Look at how glaciers in Heard Island (a sub-antarctic island) is retreating over time
Levan Tielidze@levantielidze.bsky.social · last yr.❄️ A landmark new study has revealed that glaciers on Australia’s remote sub-Antarctic Heard Island are shrinking at an accelerating rate due to rising temperatures and climate change. tc.copernicus.org/articles/19/... @andrewmackintosh.bsky.social @heardislandgov.bsky.social @arcsaef.bsky.social
This is the collapsing terminus of Rhone #glacier yesterday - retreating out of its proglacial lake. Impressive changes going on during the heat wave! We measured almost 3 meters of ice melting over the last 4 weeks... This is 10 cm of ice layer removed every single day!!
I’m delighted to share that our new paper is now out in @natclimate.nature.com! Our long-term, monthly Antarctic-wide dataset of surface meltwater shows that the East Antarctic Ice Sheet is becoming increasingly prone to surface meltwater ponding.
