Destabilization of Earth system tipping elements

(Review) suggesting key Earth system tipping points - like the Greenland Ice Sheet, Amazon rainforest, and AMOC - are losing stability and nearing critical thresholds

Interactions may mask warning signs

Destabilization of Earth system tipping elements - Nature Geoscience

A review of observation-based evidence suggests that four interconnected Earth system tipping elements have moved towards their critical thresholds, highlighting the need for better monitoring and increased mitigation efforts.

Do you think climate science needs to be better communicated? We do too! That's why we are looking for a climate science communication specialist to join the Technical Support Unit of the IPCC Working Group I.
All details can be found here: www.ipcc.ch/2025/09/17/c...
Please share!

We find robust stabilizing feedbacks between both Earth system components. Greenland meltwater may weaken the AMOC, but the then induced cooling limits further Greenland melting and hence also further weakening of the AMOC, at least in moderate warming scenarios.

Fresh of the press, a new study where we investigated the response of the Greenland ice-sheet and AMOC to warming scenarios, in a coupled Earth system model:

another (very unintuitive) finding is that the filling time of the ocean is about 2x its maximum ideal age - it takes over 3000 years to fill the mid-depths of the Pacific!
