„Näher am Kipppunkt“: Atlantikströmung AMOC schwächt sich stärker ab als gedacht – mit verheerenden Folgen
Die atlantische Umwälzzirkulation AMOC verliert deutlich mehr an Kraft als bisher angenommen. Wissenschaftler warnen vor dramatischen Folgen.

Risiko AMOC-Kipppunkt: Statt Wärme Frost für den Norden?
Kippt die atlantische Umwälzströmung (AMOC), die Heizung des Nordens? Die nordischen Länder würden dann um mehrere Grad kälter.

AMOC news can be confusing—is it slowing? Collapsing? Remaining stable? There’s studies that claim each!

Under clear skies, temperatures will tumble into single figures across many areas
The coldest rural spots in central Scotland could see lows near 3°C, with a small chance of a local grass frost by dawn 🥶

A striking climate-model result suggests AMOC may have a rate-induced tipping point.
👉 Slow CO₂ increase: AMOC stable to +5.5°C
👉 Faster increase: collapse around +2°C
Same climate system. Very different outcome. The rate of warming matters.

We find an AMOC collapse would exacerbate drought conditions across Europe, linked to reduced precipitation. In combination with climate change droughts are expected to become more frequent and severe.
