"Met de kennis van nu is het meest waarschijnlijke scenario nog steeds dat het warmer gaat worden. Alleen is dit een nieuw inzicht dat we niet kunnen negeren", zegt Deltacommissaris Co Verdaas die de werkgroep leidt. Een inzicht met verstrekkende gevolgen. Omdat de veiligheid van waterland Nederland mogelijk in het geding is, leidt de Deltacommissaris de werkgroep.

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.

#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.

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.

Ich habe mich, weil in der April-Ausgabe der @blaetter für deutsche und internationale Politik ein Text von mir über #AMOC, Klima- und Energiepolitik erscheint, mit @KarinGothe darüber unterhalten, warum auch Schwarz-Rot zu sinnvoller Energiepolitik verdammt ist. Links:

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!

Die Abschwächung der Nordatlantischen Umwälzströmung (#AMOC) könnte bis 2100 wirtschaftliche Schäden in Billionenhöhe verursachen.

Eine schwächere Strömung bindet naturgemäß weniger #CO2 im Ozean, was die #Erderwärmung weiter verstärkt. Dadurch steigen die gesellschaftlichen Kosten durch #Extremwetter wie #Hitze, #Dürre und #Überschwemmungen. Die Folgen wurden bisher wohl unterschätzt.

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.

Niu et al investigate the growth of the Eurasian Ice Sheets from the MIS 3 minimum (38,000 years ago) using a coupled ice sheet, atmosphere and ocean model. They find the rapid growth of the ice sheets happened only when there was a weak AMOC.

Jet streams are fast flowing, narrow air currents. The main jet streams flow west to east around the globe.

Because of #climate collapse, the northern polar jet stream becomes more variable. A stratospheric polar vortex disruption is linked with extreme cold winter weather across parts of Asia and North America, including the Feb. 2021 North American cold wave.

Anyway, #AMOC (the main ocean current system in the Atlantic Ocean) currently offers 12°C to Ireland:
