Out today in Nature, our new paper on the drivers of the extreme summertime heating of the North Atlantic during 2023. Temperatures across much of the basin warmed to record high levels in the space of just a few months. The impacts on climate and ecosystems were severe. A thread on how this work came about and what we found. ππππ§΅ nature.com/articles/s4158β¦
The project got started back in July 2023 when we met as a team - me, @rahmstorf and @ZhiLi_Ocean - to analyse the North Atlantic βcold blobβ β how deep it reaches and how robust it is as a measure of the strength of the Atlantic Meridional Overturning Circulation.

ππ Out today in @Nature our new paper showing how meltwater increases around Antarctica are set to dramatically slowdown the Antarctic overturning circulation, with a potential collapse this century. nature.com/articles/s4158β¦ Aπ§΅on how this work came about and what we found...
When I first looked at the Antarctic overturning circulation back in the 1990s, it was clear that models could not resolve dense shelf water formation around the Antarctic margin. journals.ametsoc.org/view/journals/β¦

Just published! Our new paper exploring the global climate response to a shutdown in the Atlantic Meridional Overturning Circulation. With @BryamOP and @AndreaTaschetto@ccrc_unsw@AntarcticSciAusnature.com/articles/s4155β¦ (... my first everπ§΅)
In this study, we demonstrate the potential for far-reaching effects, including AMOC teleconnections to adjacent basins and into the Southern Hemisphere. It all starts with a build-up heat just south of the Equator in the Atlantic....
