I had in mind David Keith's excellent vector diagram work, which I believe is unpublished at present. There he showed that geoengineering corrects all of the temperature rise, and slightly over corrects the hydro. If you correct the hydro instead of the temperature, the resulting climate is perfec

The bit that jarred with me was the IPCC comment about the hydro cycle under SRM. I don't think it expresses the science well. SRM doesn't disrupt the hydro cycle, it just doesn't fix hydro and temperature by exactly the same amount. Running SRM actually RESTORES the hydro cycle, rather than disrup
