Tien Shan glaciers are projected to lose around one-third of their 2020 ice mass before 2040, and 69-93% by 2100, depending on the climate scenario. By the late 21stC, the probability of unmet water demand in summer will increase substantially agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Peak glacier extinction in the mid-twenty-first century Have you ever wondered how many glaciers will still exist in the future? Or how many glaciers we might lose each year in the coming decades? In our new study ( Van Tricht et al., 2025 ), we shift the ...

Exceeding 1.5 °C requires rethinking accountability in climate policy A scientific foundation is required to establish nations’ responsibilities in a hotter ‘overshoot’ world.

How should climate science and policy respond to a potential exceedance of 1.5°C? We provide our perspective on this in a new @Nature comment 🔗 nature.com/articles/d41586-026-00247-y led by Gaurav Ganti with Sabine Fuss, @joerirogelj.bsky.social, @setupelz.bsky.social & Keywan Riahi 1/

Peak glacier extinction in the mid-twenty-first century - Nature Climate Change Many mountain glaciers will disappear with warming. Here the authors assess how many glaciers will disappear per year under different warming scenarios, finding that a peak in glacier loss will happen...

This is find -dot- gif

Towards the middle of the century, ~4000 glaciers worldwide will disappear every year.

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.

NCAR is quite literally our global mothership.

Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.

Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.

Unbelievable.

It's like on the eve of WWII we decided to stop funding R&D into weapons systems to develop advanced aircraft, ships, and tanks. Climate change is going to kick our butts if we lose NCAR (and NOAA) at a time when climate change is increasing extreme weather events capable of crashing the economy.

🚨 New paper ❄️

Our new study led by @landervt.bsky.social tracks the fate of ~200,000 #glaciers worldwide.

Even if warming is limited to +1.5°C, only 50% remain. With higher warming, losses accelerate, with up to ~4,000 glaciers disappearing per year.

#Glacier #extinction rates will peak within decades, with thousands of glaciers disappearing each year by 2040s. Peak extinction rates in #Alps will be reached in the 2030s.

Urgent policy action can still prevent thousands of glaciers from being lost per year.

Research involving Vrije Universiteit Brussel reveals peak glacier extinction will hit mid-century. Up to 4,000 glaciers could vanish annually. That equals the entire European Alps population. Limiting warming to +1.5°C halves this loss. #ClimateChange #Glaciers

Rising temperatures could to lead to the loss of thousands of glaciers per year, with up to ~4,000 vanishing annually under high emissions.

1.5°C could halve this loss 🧵

How many glaciers will exist by 2100 at +1.5 °C vs +4 °C warming? Our new study led by @landervt.bsky.social , projects the extinction year of ~200,000 glaciers worldwide. 🌍🧊

Can you imagine the Alps with only 20 glaciers remaining?

Glaciers Are Warming More Slowly Than Expected, but Not for Long - Eos An unprecedented dataset offers insight into the counterintuitive cooling effect of glaciers on a global scale.

As glaciers shrink in size, they will no longer be able to generate katabatic winds, and their rate of warming will begin to reflect ambient temperatures.

Damage development on Antarctic ice shelves sensitive to climate warming - Nature Climate Change Damages such as crevasses or cracks can be early indicators of ice shelf weakening. Here, the authors quantify changes in damage structures in Antarctic ice sheets, which show sensitivity to warming

🚨 New paper alert!

Research by postdoc Maaike Izeboud from the bglacier group in Nature Climate Change 🎉

Using 20 years of satellite data, she mapped Antarctic ice shelf fractures and showed how damage rises under high emissions but stabilises in low-emission futures

Damage development on Antarctic ice shelves sensitive to climate warming - Nature Climate Change Damages such as crevasses or cracks can be early indicators of ice shelf weakening. Here, the authors quantify changes in damage structures in Antarctic ice sheets, which show sensitivity to warming

24 years of satellite data reveal a dynamic, cyclic pattern of ice shelf damage across Antarctica.

Damage, linked to flow acceleration, strain, and thinning, shows strong sensitivity to climate warming, suggesting current models may underestimate future retreat.
