Out today in Nature, our paper on the drivers of the record 2023 summer heating of the North Atlantic. Temperatures warmed to record levels in just a few months. The impacts on climate & ecosystems were severe. A thread on how this work came about and what we found.πŸ‘‡πŸ‘‡πŸ§΅ www.nature.com/articles/s41...
This is not the actual cover of Nature, just shown here for illustrative purposes. We did submit this figure for consideration for their cover. Print run in two weeks, we'll know by then if it gets used.

Antarctica and the Southern Ocean hold critical clues about our changing climate – understanding this change is essential for communities worldwide.

New research published today in @nature.com shows the Southern Annular Mode (SAM) – the Southern Hemisphere’s most influential climate driver – has reached its most positive state in more than a millennium.

Want a state-of-the-art explainer on the big changes occurring in the Antarctic?

Check out this recent briefing, delivered to COP30 @iccinet.bsky.social

Very much designed for the non-expert, so don't be afraid to dip in!

The weakening of the atlantic meridional overturning circulation (AMOC - potentially causing cooler winters in Europe as often explained by @rahmstorf.bsky.social) is only part of the even faster weakening of global ocean circulation that could harm nutrients transport to the sea surface #Antarcic πŸ§ͺ

Thanks Henri! Agreed that the big problem is the commitment to future MW input, which is set to be long-lived, nonlinear, and bad for SLR and also overturning stability. And I agree the overturning will eventually re-establish once the MW input stabilises, but that could be 1000+ years away.

β€œThis is a wake-up call,” said author and ACEAS Deputy Director, @profmattengland.bsky.social (UNSW). β€œThe evidence shows us clearly that the MOC has slowed down, and if this trend continues the impacts on human societies, climate and ecosystems will be profound.”

Thank you! Yes the Antarctic MOC doesn’t drive as much poleward heat transport as the AMOC. But it is critical for recycling nutrients back to the sea surface. And there are concerns it can lead to more shelf water warming β€” an amplifying feedback.

Not downplaying the seriousness of an AMOC collapse β€” and not aiming to mislead! :-) Was just pointing out the Antarctic overturning is likely closer to being forced to a collapsed state. Did you watch the talk?

Yeah true that a Stonmel type irreversibility is not necessarily a thing hereβ€” but switching off Antarctic melt could take 1000s of years on our current trajectory. I meant a tipping point where a collapse is inevitable, and a stable off state would persist for a long long time.

"The pace of change is already at about a 30% decline. This just tells you how critically urgent carbon emissions reductions are, because we need to give this overturning circulation every chance of not tipping over what seems to be a very perilous & near tipping point"

If you’re interested in why the #Antarctic overturning circulation is very likely closer to a tipping point than the #AMOC, I touch on the topic in this 10 minute talk presented virtually today at #COP30. Starts at approx. 20 min mark.

🧊 New research reveals an overlooked Antarctic process that may skew sea level rise projections.

β˜€οΈ A team led by Dr @fabiobdias.bsky.social (ACEAS/UNSW) found East Antarctica ice shelves melt in summer bursts as sea ice retreats and warm water flows underneath.

Unfortunately not. We still have a situation where policymakers think Antarctica is too far away to matter. Nothing could be further from the truth.
