Quick Take:
...Various lines of evidence outline that ocean warming reached the highest observed levels in 2023, continuing the ongoing & accelerating trend that models suggest will continue into the future in the absence of drastic emissions reductions....

I have a commentary in Nature on our disquieting inability to work out why 2023 was so warm. www.nature.com/articles/d41...
Climate models can’t explain 2023’s huge heat anomaly — we could be in uncharted territory
Taking into account all known factors, the planet warmed 0.2 °C more last year than climate scientists expected. More and better data are urgently needed. Taking into account all known factors, the pl...

It was a lot easier to learn about AMOC from Wally Broecker, 33+ years back, then it is to read about it in real time, BTW.

New study suggests the Atlantic overturning circulation AMOC “is on tipping course”
A new paper was published in Science Advances today. Its title says what it is about: Physics-based early warning signal shows that AMOC is on tipping course. The study follows one by Danish colleague...

Why this is one of the planetary shifts scientists are most worried about
Research shows that the Atlantic Ocean’s sensitive circulation system is in danger, but scientists still don’t know how close it is to collapse.
