What if the ocean current keeping Britain warm started to slow down? ☔ The AMOC acts like a giant conveyor belt, moving heat from the tropics to our shores. Models predict that the AMOC could slow down or collapse – potentially leading to new extremes in weather. 🧵1/2

Great to speak at the Westminster Energy Forum on the latest science on the AMOC. Thanks to the organisers for the invitation and to everyone for the engaging discussion.

If you are an oceanographer you know how important Argo floats have been for our understanding of ocean hydrography & circulation, more recently, ocean biogeochemistry. Today, like everything else, they are in peril. Commentary led by @solilyquy.bsky.social Read & show your support. bit.ly/4fd2whZ

Great to chat with Justin Rowlatt for this BBC piece on the latest science surrounding the AMOC and the ongoing debate about its future 🌊 www.bbc.co.uk/news/article...

After record heat, could the Atlantic make Britain's weather even more extreme?

As temperatures rise, scientists are investigating whether a changing Atlantic could bring more volatile weather to the UK

A balanced overview of some of the latest AMOC science and debates. There is still substantial uncertainty, and while collapse cannot be ruled out, claims of very high collapse probabilities (>50%) currently go beyond what the combined evidence from observations and models can robustly establish 🌊

Yale Environment 360@yalee360.bsky.social · 3mo ago

Scientists are increasingly worried that a key Atlantic current, which delivers warmth to northern Europe and shapes weather globally, is at risk of collapse. Multiple lines of evidence suggest it may be nearing a tipping point.

New study on blocking the Bering Strait to prevent an AMOC collapse. It highlights how complex the system is. Interventions like this are unlikely to offer a simple solution. Cutting greenhouse gas emissions remains the most reliable way to reduce the risk of AMOC weakening 🌊

Building a massive dam between Alaska and Russia could prevent AMOC collapse, scientists say

Building a dam in the Bering Strait might preserve the Atlantic Meridional Overturning Circulation, but experts warn it could also threaten wildlife, Indigenous people and shipping — and could actuall...

I was quoted in this @newscientist.com article on a study linking AMOC collapse to a large CO₂ release from the Southern Ocean. “To see this play out in a warmer climate, and with such a large increase in CO₂, is quite striking.” Key uncertainties remain in how SO processes respond across models 🌊

Collapse of key ocean current may release billions of tonnes of carbon

If the Atlantic Meridional Overturning Circulation shut down, the knock-on effects could release hundreds of billions of tonnes of CO2, raising global temperatures even further

Happy to see this out! Meltwater can delay future surface warming, and its interannual variations impact ocean stratification & overturning.​​ This effect is usually absent from models. Including it as forcing may lead to more realistic simulation of surface temperature and sea ice trends🧊🌊 (1/7)

Always interesting to see this come up again 😄 Our Nature paper didn’t “redefine” collapse — there’s no single threshold, though ~6 Sv is common. We used 0 Sv only for extreme 4×CO₂ runs (full shutdown). Under real-world forcing, models stay above 6 Sv this century — no collapse. Clarified 🌊👇
