The recent increase in Antarctic Ice Sheet is driven by enhanced precipitation from frequent atmospheric rivers, stronger westerlies, and reduced sea ice, which together offset ice loss from outlet glacier discharge. @marlenkolbe.bsky.social @ruthmottram.bsky.social www.nature.com/articles/s43...

If you're interested in how ice sheets respond to climate, particularly over very long timescales, you might be interested in our new (open access) paper: www.nature.com/articles/s43...

Ethan Pierce, Irina Overeem, and Bent Hasholt have unlocked an important clue in a long-standing scientific mystery. Their new paper describes how icebergs export nutrients from Greenland into the Atlantic Ocean, a process that is being amplified by a warming climate.

Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/... And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10.... Paleoclimate evidence generally provides the strongest constraint on high ECS.

🌏 Better models = better climate predictions. A new paper led by ACEAS PhD researcher Claire Yung (ANU) shows how a refined equation used in ocean models can significantly improve the accuracy of Antarctic ice shelf melt predictions. ➡️ antarctic.org.au/new-model-co...

Come join us! 3 year postdoc available to work with @profmattengland.bsky.social, @mad-ros.bsky.social and myself at ANU on modelling ocean - ice shelf interactions. Closes 4th March. If you're going to Ocean Sciences and want to chat about it, let me know! jobs.anu.edu.au/jobs/postdoc...

To go under Thwaites Glacier, the only way is through ⬇️ This intrepid UK-Korean science team are tunnelling 1000m through one of the world's most unstable ice shelves. They'll get daily data showing how warm ocean water is melting Thwaites from below - crucial for predicting sea level rise.

Aux pôles, le climat s’emballe de façon vertigineuse, influant sur le niveau de la mer, les courants océaniques et atmosphériques. Malgré l’urgence de la situation, seul le temps long permet de saisir les changements en cours sous les hautes latitudes polaires, affirme le glaciologue Gaël Durand.

A four-year record from the heart of the Ross Ice Shelf shows how subtle changes could shape future sea level rise, ocean ecosystems – and even our weather.

Pleased to have been involved in this study. I'm always keen to see how tides affect ice, and it still surprises me that moving kilometer-thick ice up and down by just a meter or so can affect grounded ice flow tens of kilometers inland.

NEW: 2024 has just been confirmed as the warmest year on record, and the first to breach the 1.5C threshold. We used a ridgeline (Joy Division inspired) chart to visualise daily temperature anomalies since 1940. 2024 clearly stands out with 100% of its days above 1.3C and 75% above 1.5C.

Hey again ice-sheet modellers! 👋 Reminder that registration for the ISMIP7-Copenhagen workshop closes next week (Jan 15). 👇

The US Academic Alliance for the IPCC (USAA-IPCC) was formed in March 2025 in part to prepare for this possibility and to ensure that US scientists remain able to engage in IPCC work regardless of the status and role of the US government.

New research shows how climate change can push #glaciers from stable to unstable flow Using long-term observations and glacier seismology, scientists tracked how surface meltwater penetrates crevasses, reaches the glacier bed, and accelerates its flow ➡️ www.ige-grenoble.fr/Listening-to...

New paper alert! tl;dr: the seafloor of Europa is probably tectonically inert, meaning little to no active fracturing that could expose fresh rock to seawater. Without such water–rock reactions the prospect for there being life within Europa just took a big hit. A thread:

New year, new paper out in JGR:Oceans! Led by PhD Candidate Madeline Mamer - she updates a 40-year old theory for the rate of iceberg erosion by waves, to include the effect of local ocean stratification by meltwater ❄️🥼🧊🌊 doi.org/10.1029/2025...

Parker et al provide a revised model of the ice sheet margin retreat of the Ross Sea sector of Antarctica. They show there was a rapid retreat of ice shelf between about 6900 and 5400 years ago. doi.org/10.1038/s414...

Ice sheets are a major source of long-term sea-level rise. ESM2025 improved how Earth System Models represent them by enabling dynamical ice-sheet components in UKESM and IPSL-ESM. These models can now simulate ice-sheet evolution in response to climate forcing & its influence on global sea level.

Drilling a 200m sediment core from the bedrock beneath 500m of Antarctic ice is a complex process, so we've broken it down step-by-step in this explainer. From melting snow in our flubbers through to filling our core barrels, what we're attempting 700km from the nearest base is no mean feat!

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.

Over the moon that this paper is now out! A lot of work and submitted during maternity leave, but really proud of the final version. Thanks goes to all the co-authors on this. www.nature.com/articles/s41...

Our paper on a new ice shelf basal melt parameterisation is out! tc.copernicus.org/articles/19/... Small-scale processes in the ocean drive ice shelf basal melt, and large-scale ocean models can’t resolve these processes. Therefore, models use melt parameterisations, but these can still be improved.
