I¹d like to suggest that one reason that working through both the governance and the science of SRM will be so challenging is the very large jump being proposed, namely from doing no intentional climate engineering to taking control of the global climate. That is a huge leap, necessary as it may be to contemplate for some time in the decades ahead if negotiations prove as fruitless as they have so far.
It seems to me that discussions might prove more practical and possible if the discussion was about some interim types of efforts that might be explored. For example, there have been suggestions about how to potentially moderate the increased intensification of hurricanes/tropical cyclones, which are suggested to be one of the adverse consequences of climate change. One approach suggested was to position barges in the track of storms and vertically mix ocean waters to cool the surface waters and reduce the ability of the storm to draw heat from the ocean; another approach proposed has been to use cloud brightening over an extended time to cool the waters that such storms typically pass over, so reducing the statistical likelihood of very severe storms rather than trying to limit the intensification of a particular storm. For those living, for example, in the southeastern US and Caribbean basin, or in the Philippines, Indonesia, Japan and East Asia, research to figure out if such a moderation could be be done (and there was once an indication that the Department of Homeland Security might be supporting such research) and to consider the many social science and governance issues might make for a much more focused and hopefully productive discussion. Similar discussions might focus on a number of additional specific interventions that might or might not be technically feasible and might or might not be conceivable in terms of governance and societal implications. Examples that might be considered might include seeking to cool the Arctic/slow permafrost thawing/slow loss of mass from ice sheets, seeking to modify storm tracks in order to moderate areas of intense drought, seeking to offset the loss of sulfate cooling that will come from closing down coal-fired power plants, and there are surely other ideas. Each of these proposals has a quite specific goal in mind as opposed to reversing the increase in global average temperature. Some would mainly affect (in terms of beneficial and/or harmful influences) far fewer numbers than the full global population. It just seems to me that exploring the potential issues (in terms of the physical and socio-political-ethical aspects) would make for a much more focused and manageable discussion that would help to provide insights for moving on to the possible need for a full global intervention (and it is for this reason my recent papers have focused on such possibilities). I don¹t really know if any could actually be made to work in a scientific sense (yes, doing something in one spot affects everywhere, but is the effect noticeable everywhere and how would such an effect compare to the ongoing changes that are occurring‹so there are issues of relative importance of an effect, etc.), and I don¹t know if regional governance (e.g., as might be most relevant in the case of offsetting Arctic warming or moderating tropical cyclone intensification) would make the discussion of societal and ethical aspects any easier, but it does seem to me that there is the potential for more insightful, productive, and even relevant discussion if the jump from doing no climate engineering were to potential quite focused interventions than to taking full global control.
