Die Meere heizen sich auf, verlieren Sauerstoff und versauern, der Meeresspiegel steigt, die Meeresökosysteme sind immer stärker unter Druck.
Wir leben auf einem Ozeanplaneten, und was mit unseren Meeren geschieht, wirkt sich bereits auf uns an Land aus.

Weltmeere: Hitzewellen in den Ozeanen

Die Meere erwärmen sich immer schneller, Nord- und Ostsee ganz besonders. Das geht aus dem Statusbericht des Copernicus Marine Service hervor.

Mein Interview mit Dunja Hayali beim heute journal vom Extremwetterkongress in Hamburg.
Steuern wir auf 3 Grad globale Erwärmung zu (das wären 5-6 Grad in Deutschland)? Und was würde das bedeuten? Haben die Klimaforscher klar genug kommuniziert?

Did you know tiny algae can "skate" within Arctic sea ice? ⛸️ Our new study in @pnas.org reveals the secret life of ice diatoms: they are actively gliding to navigate the ice! This adds a new dimension to the sea ice ecosystem, revealing an active, dynamic ecological niche. @prakashlab.bsky.social

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100.
Our paper on that is out today.🧵
