Hi Pete, In "solar geoengineering" and "deployment", do you include all SRM technolohgies and methods, or only SAI? Bw Renaud

These include not only the choice of > whether to deploy solar engineering, but decisions regarding how to deploy, > and ongoing decision-making throughout deployment. Research on the > governance of solar geoengineering to date has primarily engaged only with > the question of whether to deploy. We examine the science of solar > geoengineering in order to clarify the technical dimensions of decisions > about deployment – both strategic and operational – and how these might > influence governance considerations, while consciously refraining from > making specific recommendations. The focus here is on a hypothetical > deployment rather than governance of the research itself. We first consider > the complexity surrounding the design of a deployment scheme, in particular > the complicated and difficult decision of what its objective(s) would be, > given that different choices for how to deploy will lead to different > climate outcomes. Next, we discuss the on-going decisions across multiple > timescales, from the sub-annual to the multi-decadal. For example, feedback > approaches might effectively manage some uncertainties, but would require > frequent adjustments to the solar geoengineering deployment in response to > observations. Other decisions would be tied to the inherently slow process > of detection and attribution of climate effects in the presence of natural > variability. Both of these present challenges to decision-making. These > considerations point toward particular governance requirements, including > an important role for technical experts – with all the challenges that > entails. > > *Key policy insights* > > - > > Decisions about solar geoengineering deployment will be informed not > only by political choices, but also by climate science and engineering. > - > > Design decisions will pertain to the spatial and temporal goals of a > climate intervention and strategies for achieving those goals. > - > > Some uncertainty can be managed through feedback, but this would > require frequent operational decisions. > - > > Some strategic decisions will depend on the detection and attribution > of climatic effects from solar geoengineering, which may take decades. > - > > Governance for solar geoengineering deployment will likely need to > incorporate technical expertise for making short-term adjustments to the > deployment and conducting attribution analysis, while also slowing down > decisions made in response to attribution analysis to avoid hasty choices. > > > https://www.tandfonline.com/doi/full/10.1080/14693062.2019.1668347 > > Ping me and I can send a copy if you don't have access. > > Cheers, > > Pete > > -- > You received this message because you are subscribed to the Google Groups > "geoengineering" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/geoengineering/90cf14fd-59c6-4baf-9263-bd4a2fd38457%40googlegroups.com > <https://groups.google.com/d/msgid/geoengineering/90cf14fd-59c6-4baf-9263-bd4a2fd38457%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
