The #IPCC #SR15 report says very little about solar #geoengineering, which is the main, but not only subject, of my book #ThePlanetRemade beyond saying that there is high agreement that a particular form of it could keep temperatures below 1.5C (Cross chapter box 10 in Chapter 4)
If the IPCC not going into this more seems an odd omission, given the topic, I think it is because a) the scientific understanding on solar #geoengineering, which obviously will never be complete, is still pretty sketchy in many respects (though not as sketchy as some may think)
b) the structure that the IPCC chose for the report (which was forced on it in part by the UNFCCC's mandate to it) did not allow it o assess solar #geoengineering's potential contribution in any of its scenarios
