The Northern Pacific Ocean is currently smashing temperature records. And it is reaching these levels far earlier than the current generation of climate models had expected. A short thread 🧵

🚨New paper on Southern Ocean CO2🚨 Using a suite of Earth system models, Maddie Shankle et al show that better ventilation of intermediate waters in the North Pacific ends up reducing outgassing of CO2 in the Southern Ocean 🌊🧪⚒️🧵 @earthscista.bsky.social www.nature.com/articles/s41...

Crab-like creatures are famed for having evolved five times in evolutionary history. But anteaters have evolved at least 12 times--in half the evolutionary span. Cool story by @jakebuehler.bsky.social for @science.org

Palaeo-validation strengthens future rainfall projections: During HS1, AMOC slowdown drove tropical rainfall shifts via Atlantic cooling & wind-driven teleconnections. Climate models show the same under warming; boosting confidence in future hydroclimate risks. www.nature.com/articles/s41...

We figured out a cheap-ish way to make ocean models create Dense Shelf Waters (DSW) on the surface of the Antarctic continental shelf! How? Fast answer: Ocean surface cells thinner than 1 m! Long answer on the paper: dx.doi.org/10.1029/2024... ---- More info in the thread

another (very unintuitive) finding is that the filling time of the ocean is about 2x its maximum ideal age - it takes over 3000 years to fill the mid-depths of the Pacific!

A new paper in The Lancet, one of the world’s foremost peer reviewed medical journals, estimates that USAID prevented 91 million deaths across 133 countries over 20 years. The paper estimates that Elon Musk’s DOGE funding cuts to USAID will lead to 14 million deaths by 2030 (4.5 million children).

1️⃣ Like a heartbeat driving one of the largest seasonal cycles on Earth, Antarctic sea ice is central to the global climate system and vital for unique ecosystems.

“We’re using simulation tools built on 30 to 50-year-old concepts to understand the most complex and rapidly changing ecosystems on Earth. And that’s a real problem – not just for science, but for policy and for wider society." #modelling #climatemodels

Ocean Alkalinity Enhancement (OAE) is a marine CO2 removal method that uses alkaline material to increase the storage capacity for anthropogenic CO2 in seawater. Kiyas investigated how hydroxide (NaOH) induces taxonomic shifts in plankton. She found: 👇 🌊 onlinelibrary.wiley.com/doi/10.1111/...

Check out our results on abrupt shifts in climate models: dx.doi.org/10.1029/2025... We scan the CMIP6 database for abrupt shifts and analyse the results for the subpolar gyre, sea ice, and other subsystems. Already at low levels of global warming there is a risk of large-scale abrupt shifts.

Now published in @agu.org Geophysical Research Letters! What happens to marine archaea when they’re hungry? And what does that mean for the TEX₈₆ paleothermometer? Full paper here: doi.org/10.1029/2025... Thanks to my coauthors and mentors for their support — and stay tuned, more is coming!

Woah! Such an important study published in Nature today! Quick thread with some of their key figures! 🧵

What's fun about this idea is that the oldest chimpanzee (genus Pan) fossils are ~500,000 years old, while the oldest 'human' (genus Homo) fossils are ~2.8 million years old. *We* might be the ancient ones. 🙊

Our paper on "Mid-Pliocene Climate Forcing, Sea Surface Temperature Patterns, and Implications for Modern-Day Climate Sensitivity" is now published in Journal of Climate. tl;dr: Non-CO2 boundary conditions in the mPWP contribute significant effective radiative forcing, and alter feedbacks and ECS.

What is common knowledge in your field, but shocks outsiders? By age 60, you'll have >100 billion cells containing mutations in genes related to cancer ('driver genes'). That's 2-3% of all your nucleated cells. You're accumulating ~20 mutations PER CELL PER YEAR ... but still no super-powers.

Conditions in the Antarctic winter can be pretty hostile, but science continues... this is deployment of an instrument that is lowered to just above the seabed, and gives us data on ocean temperature, salinity, oxygen content, and other important variables. 🧪🌊🥼🌊
