Southern Ocean Vertical Carbon Stratification Across the Mid‐Pleistocene Transition Breakdowns of Southern Ocean carbon isotope stratification occur at multiple glacial terminations back to at least 1.55 million years ago An increasingly efficient Southern Ocean biological pump ...

Fantastic work by Aidan Starr, @ianhall.bsky.social & colleagues published in Paleo Paleo yesterday: Subsurface-to-deep C isotope gradients in the Southern Ocean across the MPT! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

That's a great study. Although I would not go for Gemini.

The Great Ocean Sync: How Melting Arctic Ice Links the World’s Most Powerful Currents This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Evolving synchronization of the Gulf Stream and Kuroshio-Oyashio Extension in a changing climate” by Joh et al. (202…

Have you noticed synchronized SST anomalies between the Pacific and Atlantic in global maps? It’s not a coincidence. According to a new study in Science Advances by Joh et al. (2026), this "oceanic handshake" is directly linked to the retreat of Arctic sea ice. 🌊🧪 ocean2climate.org/2026/03/01/t...

yes!

I dread the comments time.

Goodmorning. Wow.

yaaay! Congrats Ale. Looking forward to more to come.

A poster being held by my friend because I forgot to ask someone to take my photo while it was actually hung up

I crunched the numbers, and Glasgow was almost 1% oceanographers this week. Happy to have given my first ever poster at #OSM2026! 🌊🏴󠁧󠁢󠁳󠁣󠁴󠁿

Greece to Acquire Nazi Execution Photographs That Were Up for Sale Online

The only photographic evidence of one of the most profoundly important events in modern Greek history, resurfaced last week, in a profoundly mundane Ebay auction. Been reeling over it for days. Awe and reverence. www.nytimes.com/2026/02/20/w...

There are big fascists and there are small fascists. You don’t see the latter. They hide behind the big fascists. But they can inflict as much damage.

This is very promising new from the NASA administrator after Congress, in a bipartisan manner, restored deep cuts proposed by the WH. NOAA and NSF budgets were also mostly restored. Checks and balances still have a faint pulse...

And just like that! The ZOD is done. #IPCC_AR7 Off to greater things!😅🙌🥂

It should not be only of European economies. The impacts will be large I other areas of the world; in systems like the Amazon and the Indian monsoons.

A Nordic Perspective on AMOC Tipping This report is the outcome of the Nordic Council of Minister’s sponsored workshop arranged in October 21-24, 2025 in Helsinki and Rovaniemi, Finland as part of Finland’s council presidency theme resil...

While I am delighted to see this work published after collaborating with some of the field's greatest scientists, I am deeply unsettled by the consequences a potential AMOC collapse would have on communities and ecosystems. Here is to hoping global leaders take note. pub.norden.org/temanord2026...

My village made it to New York Times (and Science and PNAS). www.nytimes.com/2026/01/26/s... Great work @katharv.bsky.social

🥵 2024 El Niño pushed us over 1.5°C, making it the hottest year on record:

heatwaves
floods
hunger for +110 mln people
$3.4 trn in costs

Could such extremes trigger tipping points too?
