@Sustainable2050 Any idea how long developments around the #AMOC area already seriously looked at in research? 10-15 years at least?

Finally, the Netherlands is seriously looking into the effects of a possible weakening/collapse of the Atlantic Ocean heat circulation. This could mean significantly colder winters for the Netherlands.

- What the AMOC is and why it is being ignored
- The impacts of a changing AMOC for both the environment and humanity
- What can be done to prevent this change
- Who needs to take action"
In 1989 James Burke produced a documentary named "After the Warming" which highlighted the effect of slowing the global thermohaline circulation current.
"That was the key to everything. Change the saltiness of the Atlantic and you change the world's weather."

#AMOC: The Atlantic’s Hidden Tipping Point - that is the topic of a short explainer video which I did for the Climate Crisis Advisory Group, with Tori Tsui.

(My two cents: As long as we keep igniting carbon bombs in exponential manner, no amount of geoengineering will be able to mitigate the effects.)
New summary by @rahmstorf
Is the Atlantic Overturning Circulation Approaching a #TippingPoint?
"But the fact that all these studies, using different methods, point in the same direction, toward a risk that is much larger and earlier than we had thought until a few years ago, is a major concern. My assessment of these ... studies is that by the time they can provide a reasonably reliable warning of an impending #AMOC tipping, it will be too late to prevent it."

Between the last glacial maximum & today, humans were exposed to severely rising sea levels
& recurrent phases of strong abrupt cooling events.
#MPIM researchers have uncovered the origin of these strong temperature fluctuations over the past 20,000 years using a novel coupled climate-ice sheet model. They found that #iceberg armadas
& changed river courses were responsible for #AMOC weakening & abrupt cooling.

Im aktuellen CEN Newsletter geht es darum, wie KI für bessere Sturmflut-Prognosen sorgt, welchen Preis eine Abschwächung der AMOC hätte und wie Tiden die CO2-Speicherung in den Meeren beeinflussen. Jetzt abonnieren und nie wieder etwas verpassen: https://www.cen.uni-hamburg.de/press/newsletter.html
Good AFP fact check on false claims by notorious climate misinformer Anthony Watts about the risk of a major weakening of the Atlantic Meridional Overturning Circulation, known as #AMOC.
It is laudible that AFP makes the effort to sort science from lobbyist distortions!

Schwächere Meeresströmung = Billionenkosten? Eine #AMOC-Abschwächung senkt die #CO₂-Aufnahme des Ozeans, verstärkt die #Erderwärmung & treibt Kosten in die Höhe - das fanden die Forscher @felixschaumann & @Edu_Alastrue in ihrer neuen Studie heraus. In diesem short Wissen-Was-Video fasst Carolin Riethmüller das Wichtigste für Euch zusammen (2:45 min)

"- wind driven flow of water in the Southern Hemisphere would keep the AMOC flow slightly above zero
- havoc would still be wreaked on the Earth
- this new paper is not in disagreement with previous work, but adds to our understanding of the AMOC"
"A total #AMOC collapse is unlikely this century. But even weakened currents would cause profound harm to humanity. 'In the short term, it doesn’t really matter if we have a strong weakening, say 80%, or a collapse.'"
But at least the headline is unrealistically encouraging :)

AMOC slowing, tipping point, collapse and the effects explained
@metoffice @nature it doesn't 'reveal' that. It may suggest it, but short of a time machine or a very perfect model, you can't 'reveal' things that haven't happened yet.
Obviously, every successive year in which #AMOC hasn't yet collapsed is good news for north western Europe. I'm not knocking that. But the future is as yet unknowable.
A major motor for the global #climate is beginning to falter: a massive system of #ocean currents called the Atlantic Meridional Overturning Circulation (#AMOC).
A weaker AMOC could produce long-term costs amounting to several trillion euros by the year 2100.
Weakening AMOC would further accelerate climate change because less CO₂ is transported from the surface ocean to the deep ocean. More CO₂ remains in the #atmosphere, which accelerates global warming.

Atlantin termohaliinikierron (AMOC) pysähtymisriski ennustettiin jo 30 vuotta sitten Saksassa. "Mielenkiintoista mikä oli tutkimuksen taso tuolloin! Vaatimani #AMOC-havaintojärjestelmä on ollut olemassa vuodesta 2004: RAPID-projekti. AMOC-trendi on laskeva", kirjoittaa professori
Das ist heute vor 30 Jahren erschienen!
Interessante, wie damals der Forschungsstand war! Das von mir geforderte Beobachtungssystem der #AMOC gibt es seit 2004: das RAPID Projekt. Der Trend der AMOC zeigt bergabwärts.
