If we limit warming to the Paris Climate Agreement of 1.5ºC, then we don't have to worry about dangerous levels of sea-level rise, right? Actually, no. Our research suggests that this is too warm. 🧵 1/n phys.org/news/2025-05...

Birch Glacier Landslide - AntarcticGlaciers.org The collapse of Birch Glacier and the devastating landslide that impacted the Swiss village of Blatten occurred as a result of supraglacial landslides.

Some thoughts on the #Blatten landslide, drawing heavily on the vital and excellent updates from @subfossilguy.bsky.social and @davepetley.bsky.social

Shear‐Layer Thickness and Structure Evolves With Effective Stress in Subglacial Environments A non-monotonic relationship between effective stress and deformation emerges from competing properties induced by a till's contact network Effective stresses affect not only shear-layer thicknes...

New paper using DEM and continuum modeling identifies the source of the non-monotonic subglacial sediment flex measured by @subglacial.bsky.social! dx.doi.org/10.1029/2024...

'Glacier Mass Balance Intercomparison Exercise' ❄️🧊

Huge effort to gather mass loss estimate outside ice sheets btw 2000 and 2023 📈

Since 2000, 5% ice volume lost globally (273 gigatonnes/yr) 🌊

Guess who 'won'? 🥇
Alps and Pyrenees lost 39% of their 2000 volume! 😲😱

Antarctic ice shelf kept its cool during the last interglacial period An ice core suggests that the West Antarctic Ice Sheet lost ice 125,000 years ago, but not to the extent proposed by some scenarios.

A data-consistent model of the last glaciation in the Alps achieved with physics-driven AI - Nature Communications This study employs a physics-informed AI model to reconstruct the last glaciation of the European Alps with high accuracy. The approach reduces ice thickness errors by 200–450%, yielding insights into...

We have a paper out today in @naturecomms.bsky.social on modelling the last glaciation of the European Alps, resulting in a substantial decrease in long-standing model-data misfits ! doi.org/10.1038/s414...

These are fantastic small grants for Early Career Researchers working on Antarctic Science projects. Supervisors - please point your students towards them. A huge range of projects and people have been funded over the years.

Linear-viscous flow of temperate ice Accurately modeling the deformation of temperate glacier ice, which is at its pressure-melting temperature and contains liquid water at grain boundaries, is essential for predicting ice sheet discharg...

Check out our paper that came out in @science.org today. It uses some really cool experiments to explore the rheology of temperate ice. We find that contrary to colder ice this warm ice has a value of n=1!!

Fantastic!

Viedma Glacier is one of the largest (900 km²) and thickest (1400 m) glaciers in south America! ❄️
It flows from Cerro Francisco Perito Moreno (3470 m asl) to Lago Viedma (252 m asl) 🌊

Strongly recommend this fantastic opportunity!

Abrupt changes in biomass burning during the last glacial period - Nature An increase in wildfire extent and related greenhouse gas emissions can be linked to abrupt climatic changes during the last glacial period.

I'm thrilled to share our new @nature.com paper! We present ice core methane isotope data revealing that past abrupt climate changes likely triggered surges in wildfires, simultaneously driving rapid methane—and possibly CO2—rises 🌎🔥

Shifting Antarctic Circumpolar Current south of Africa over the past 1.9 million years Shifts in the world’s largest ocean current are closely linked to Southern Ocean upwelling during warm intervals in Earth’s past.

Blwyddyn Newydd Dda / Happy New Year 2025!

Great to see our latest IODP EXP 361 paper out today:

Shifting Antarctic Circumpolar Current south of Africa over the past 1.9 million years www.science.org/doi/10.1126/...

Quite happy that I got the window seat and flew over the LGM moraines. Bonus point: found the coolest plate!

Had a great time sampling for cosmo dating in Los Alerces National Park in Argentina with colleagues from CONICET
