It is well established that a collapse or strong reduction of the Atlantic meridional overturning circulation (AMOC) would substantially cool the northern high latitudes. Here we show that there is a possibility that such cooling could be amplified under deliberate CO removal and result in a temporary undershoot of a targeted temperature level. We find this behaviour in Earth system models that show a strong AMOC decline in response to anthropogenic forcing.

Reducing such uncertainties is required to effectively guide the development of climate mitigation policies for meeting the ambitious climate targets of the Paris Agreement. Here, we show that the large spread in the projections of future excess heat uptake efficiency and cumulative anthropogenic carbon uptake in this region are strongly linked to the models' contemporary stratification.

- Ocean biogeochemistry and photochemistry significantly impact the exchange of trace gases between the ocean and atmosphere, which are vital for understanding Earth's climate.
- Ocean acidification (OA) influences the production of key trace gases like dimethyl sulfide (DMS), nitrous oxide, ammonia, and halocarbons, especially in sensitive regions like polar oceans and areas with upwelling.
- To enhance knowledge of trace gas production mechanisms and adaptations, the study suggests integrating short-term process measurements with long-term experiments in both lab and natural settings, while advocating for more comprehensive ocean observations that include carbonate chemistry metrics.
