Wow! There is a detailed and well referenced section (3.2.3.4) that largely dismisses solar geoengineering. There's a lot in here that needs careful reading before reaching an informed conclusion. It may be that a carefully researched rebuttal is called for rather than knee jerk reactions. Their conclusion is:
We strongly caution against reliance on solar geoengineering as a major tool for preventing tipping points, or the expectation that this kind of approach will be available and politically acceptable in the future to contribute to prevention efforts. Nor should SRM ever be considered a possible replacement for mitigation.
What I have yet to see in the report (it's
494 pages!) is how reduced emissions and GGR will do the trick.
Hopefully that's a surprise lurking somewhere yet to be found.
