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
c) there are a great many issues surrounding solar #geoengineering, ranging from those of biogeophysics to those of justice, which are worrying and problematic (the report does discuss some of these, since it can look at potential downsides more easily than upsides)
and d) the climate science community is broadly sceptical both of the wisdom of pursuing solar #geoengineering research more whole-heartedly and of the wisdom of talking about it as a possible part of the overall response to global warming, lest people get the wrong idea.
If you want to know more about the physical side of the solar #geoengineering, I'd recommend starting with whichever of these papers by @peteirvine tickles your fancy

And there is some excellent discussion of broader issues raised here

That said, I also believe, unsurprisingly, that my book is pretty good, too, and not that out of date.
