Many studies have confirmed the finding and explored potential triggers and likely implications. Until recently, AMOC collapse caused by human activity fell into the category of a “high impact, low probability” event, devastating if it happens, but unlikely to occur. Research over the past few years prompted a reassessment: to look more like a “high impact, high probability” event.A billionaire death cult has its fingers around humanity’s throat. It both causes and downplays our existential crisis. The oligarchs are not just a class enemy but, as they have always been, a societal enemy: a few thousand people can destroy civilisations. It’s the billions v the billionaires, and the stakes could not possibly be higher.https://www.theguardian.com/commentisfree/2026/apr/23/catastrophic-climate-event-scientists-atlantic-system-collapse-billionaire-existential-crisis#Climate #Science #Ocean #Nature #AMOC #ClimateDiary #Environment #ClimateCrisis #Billionaires #FossilFuels #USPol

@gimulnautti Yes! “Oh fuck” indeed! Very scary

@touaregtweet @maartenkoning Utrecht University researchers R.M. van Westen et al. published similar in August last year, “Physics-Based Indicators for the Onset of an AMOC Collapse Under Climate Change“, J. Geophys. Research, https://doi.org/10.1029/2025JC022651

@rahmstorf is this a self accelerating effect or is there something that stabilizes it?

We have a new preprint out for open review at Ocean Science, which discusses the evidence for the #AMOC already slowing. If you have any comments, counter-arguments, or things we may have missed - please post them there! (Or here.)Thanks!https://egusphere.copernicus.org/preprints/2026/egusphere-2026-2110/

Bedeutet ein stabiler oder zunehmender Ein- und Ausstrom vom Atlantik ins Nordmeer, dass die #AMOC stabil ist, wie manche argumentieren? Nein. Das Gegenteil ist richtig:https://www.pik-potsdam.de/de/aktuelles/nachrichten/neue-studie-nordische-meeresstroemung-wird-staerker-waehrend-sich-amoc-abschwaecht

@angeldruckt @rahmstorf ja, wenn man die Vorzeichen ignoriert kommt die Apokalypse völlig überraschend, trotz der Prophezeiung.

New study: most climate models underestimate the decline of the Atlantic overturning circulation #AMOC. The AMOC is on course to slow by more than 50% by the end of the century. Very likely the AMOC will then be past the tipping point for full shutdown. https://us.cnn.com/2026/04/16/climate/atlantic-ocean-circulation-collapse-update

@markhburton Thanks. But the Guardian article does provide a direct link to the paper too. Somewhere in the middle where it says "The new research, published in the journal Science Advances, explored four different ways .." , the link is highlighted.

@StefanMuenz wobei (wenn wir nur von Klimaanpassung sprechen) +40° im Sommer mit Photovoltaik auf angenehme ~20° runterkühlen deutlich einfacher fällt, als -40° im Winter mit Erneuerbaren auf +20° zu heizen.

Climate models show considerable discrepancies in their future projections around the Atlantic, mainly due to uncertainties in the fate of the Atlantic Meridional Overturning Circulation (#AMOC).#Climate models have previously suggested a reduction in AMOC strength of 32±37% by 2100.But a closer examination, however, gives an estimate of the AMOC slowdown of 51±8%.This refinement mainly results from correcting a bias in South Atlantic surface #salinity, consistent with recent studies emphasizing its role in the proximity to an AMOC tipping point.This more substantial AMOC weakening has key implications for future #adaptation strategies.https://www.science.org/doi/10.1126/sciadv.adx4298

@rahmstorf isn't unexpected...
