BEFORE/AFTER #Dharali disaster! 😱
June 13 / August 7

Incredible extent of destruction and sediment deposition on the fan.
Precise cause of flood is still unknown.
Some sources mentioned possible GLOF.

Look at how glaciers in Heard Island (a sub-antarctic island) is retreating over time

Proud of you 🙌

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!!

Continent-wide mapping shows increasing sensitivity of East Antarctica to meltwater ponding - Nature Climate Change This study provides a continent-wide assessment of surface meltwater area in Antarctica between 2006 and 2021, highlighting recent increases in magnitude and variability in East Antarctica, with indic...

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.

My views on climate warming and glaciers. What the future gonna look like?

A busy couple of weeks for the Losing their Cool team - we've drilled, cored, installed thermistors & erected an AWS, all at 6500m beneath the Lhotse Face. Next challenge is to get a flight out of Lukla 😄 @matt-peacey.bsky.social @climatom.bsky.social @unileedsnews.bsky.social @envleeds.bsky.social

I recently got an opportunity to speak on glaciers and how would the world look like if the climate is continuously warming up, and glaciers are losing mass.

Tried my best to communicate from my experiences and domain knowledge in this podcast!

BC - a big threat to glaciers!

Best wishes! 🙌

Sharing some of my interaction with penguins on #WorldPenguinDay in #Antarctica and Cape Town

What does the glacial geomorphology tell us about the past? Imagine standing in a wide, U-shaped valley, high up in the mountains. The air is crisp, the wind whistles through rocky outcrops, and all around you is silence.

Properly mind-blowing event yesterday east of Annapurna II (NE face visible here, 7,937 m, Nepal)! 😱

Probably triggered by ice (+rock?) avalanche at high elev., given the reach and the absence of snow at the moment 🧊

The extent of the aerosol is... HUGE! ❄️🌪️

How hidden lakes threaten Antarctic Ice Sheet stability For decades, satellites have played a crucial role in our understanding of the remote polar regions. The ongoing loss of Antarctic ice, owing to the climate crisis, is, sadly, no longer surprising. Ho...

Tschierva Glacier

One of my fav glacier in the Alps, because of its (past) aesthetics and the huge amount of subfossil wood there (www.sciencedirect.com/science/arti...)
...now sealed under 5 million m3 of rock fallen in 2024 (before last pic)!

I never expected, 130 people to turn up and listen to me (just an enthusiastic guy, wanting to talk about glaciers). Watching all engage, ask questions, and reflect on what I spoke, reminded me why I do what I do. Science is also about stories, emotions, and the impact we can create together.

It was a great opportunity to talk about Antarctica, the Himalayas, and climate science on the 1st UNESCO World Day for Glaciers in my loving hometown- Chandannagar, among people who have been admiring my journey and my adventures since I was a small kid.

Different shot, this time in natural color.

More than half a billion years ago on a frigid, ice-covered Earth, glaciers stirred up ingredients for complex life by bulldozing land minerals and then depositing them in the ocean, according to a new study. cnn.it/4hTgeql
