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.👇👇🧵 www.nature.com/articles/s41...

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 🧪

“This is a wake-up call,” said author and ACEAS Deputy Director, @profmattengland.bsky.social (UNSW). “The 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.”

"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"

Why have the sea surface temperature suddenly risen in 2023/24? 🌊
Is it true that climate models cannot simulate such SST jumps? What is common to such jumps? How will SSTs evolve over the next months and years? Are we in uncharted territory? More from our recent study in Nature is here👇
