IMHO you left out one very important sentence just before the part you've quoted: "A full AMOC collapse would be a massive, planetary-scale disaster. We really want to prevent this from happening." And uncertainty here is not if it will ever happen - we know it will eventually, if the temperature continues to rise - part we're unsure of is only whether it will happen before 2100, or later. Which makes the following part of the text a real conclusion for me: "For the AMOC and other climate tipping points, the only action we can take to minimize the risk is to phase out fossil fuel use and stop deforestation as fast as possible. If we can reach zero emissions, further global warming will stop within years, and the sooner this happens the smaller the risk of passing devastating tipping points. It would also minimize many other losses, damages, and human suffering from “regular” global warming impacts (e.g., heatwaves, floods, droughts, harvest failures, wildfires, sea level rise), which are already happening all around us even without the passing of major climate tipping points."
