yeah .. but the point is that we need the cooling effect of particulates asap over the next 2 decades of peak heat, not in 50 years “later this century”.
It could well be that AMOC has already tipped .. do we also want to do nothing and risk further tipping points, such as the Antarctic ice sheet melting and subsequent meters of sea level rise ?
Misleading title by the Author of the summary article, imo :

> Pflüger and his colleagues simulated two aerosol injection scenarios, both with high carbon emissions. In one scenario, people started slowly adding particles into the atmosphere in 2020. In the other, beginning in 2080, people inject a large initial quantity of aerosols to bring the amount of warming back to 1.5 degrees Celsius and then continue to add enough aerosols to maintain that level of cooling.
> **The team found that in the 2020 scenario, gradual stratospheric aerosol injections maintain ocean temperatures, structure, and circulation patterns roughly similar to today.**
That sounds a lot like atmospheric geoengineering actually **COULD** save the ocean currents / amoc, if we take urgent action.
