The article mentions that:
> Stratospheric SO2 rains out of the atmosphere after a year or so, so unlike CO2 emissions it is relatively easy to control the dosing and the magnitude of the desired effect
Is this not true? I'm curious about where I can read more about research about the lifetime of atmospheric SO2.
Edit: The best source I could find about stratospheric SO2 was based on measurements after Pinatubo at

I see that the concentration declined to roughly 1% after 180 days (Figure 7). Volcanic aerosols seem to last a bit longer but seem to go back to background around 4 years (Figure 10).

- rtpg 3y agoOne sort of point was a recent article going around showing that sulfur output from cargo ships was lowered recently, and this seems to have lead to a noticable increase in ocean temperatures along shipping routes. So the cut in sulfur lead to measurable changes less than a year into this change (and the change has seemed to be consistent). In peer review but if that holds this would probably have similar qualities.
