An interesting new study has examined 20,736 scientific publications about climate tipping points. Several of those are estimated to be crossed around 1.5 degrees warming, i.e. any time soon: permafrost thaw, Greenland Ice Sheet, North Atlantic Subpolar Gyre.

Kennt die Politik eigentlich gar keine Regeln für Interessenkonflikte? Aus einer Gasfirma ins Amt kommen, und dann das:
“Die Gaslobby wird von dieser Ministerin mit Steuern subventioniert und gefördert, während sie die Förderung der Erneuerbaren kappen will.”
Lesenswert!

@rahmstorf.bsky.social

Die Erderwärmung beschleunigt sich, der vergangene Hitzesommer hat uns in 🇩🇪 16.000 Tote (RKI) und 40 Milliarden € (DIW) gekostet.
Und Ministerin Reiche will den dringend notwendigen und erfolgreichen Ausbau der Erneuerbaren sabotieren! 🤯
Unverantwortlich. 😠

taz.deDas große RollbackEigentlich sollte Katherina Reiche (CDU) die Wirtschaft ankurbeln. Doch ihre Gesetze für den Strommarkt sind dazu nicht geeignet. Was genau will die Bundeswirtschaftsministerin?

Establishing an Amoc Observatory! "A highly respected, impartial reference body, regularly updating concerned nations, could do for Amoc what disease-surveillance networks already do for pandemics." Ja, Sverige måste delta!

A new preprint from the UK Met Office, Hadley Centre and others has analysed Atlantic Ocean heat loss and finds it has declined over the last 30 years. That points to an #AMOC that has already started to weaken, as climate models have predicted. 🌊

researchsquare.comEvidence the ocean is losing less heat in the northern Atlantic and the AMOC has started to slowly weakenThe Atlantic Meridional Overturning Circulation (AMOC) is widely expected to weaken this century, with potentially large impacts on Europe, but the strength and timing of weakening is still uncertain....

A well-researched article from Politico on one of the major climate risks: the linked tipping points of the subpolar gyre #SPG and #AMOC in the Atlantic.
"There’s a substantial risk that it can happen within the coming 20 years,” says @swinda.bsky.social from Utrecht Uni about SPG collapse. 🌊 1/4

Great piece on the AMOC, with attention for the subpolar gyre. While AMOC collapse would take multiple decades, potential changes in the subpolar gyre could occur over 10-15 years and start as early as 2040. The impact won't be as severe as for AMOC, but this near-future risk warrants attention.

“Es gibt gar keine globale Erwärmung, das ist alles nur Illusion von Messungen in Städten durch den städtischen Wärme-Insel Effekt!” Lese ich seit 30 Jahren von “Klimaskeptikern” - teils bis heute 🙄.
