What are the most important things we know about solar geo-engineering?
* It can be done, it is comparatively cheap, but probably not as cheap as people think * It will cool the planet, but it will not simply cancel out greenhouse gas additions * There is more than one way of doing it, some are more reversible than others * It is no substitute for balancing the carbon budget * It acts fast, but needs constant maintenance What are the most important things we don’t know about solar geo-engineering * Who decides * Who pays for the unintended side effects * What are the unintended side effects for different methods under consideration * Benefit – risk analysis over time From: <kcalde...@gmail.com> on behalf of Ken Caldeira <kcalde...@carnegiescience.edu> Reply-To: "kcalde...@gmail.com" <kcalde...@gmail.com> Date: Wednesday, July 19, 2017 at 07:48 To: Geoengineering <Geoengineering@googlegroups.com> Subject: [geo] Help: What do we know and what don't we know about solar geoengineering? Folks, This Sunday evening, I am supposed to help kick off a discussion about what we know and what we don't know about solar geoengineering. https://www.grc.org/programs.aspx?id=17348<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.grc.org_programs.aspx-3Fid-3D17348&d=DwMFaQ&c=l45AxH-kUV29SRQusp9vYR0n1GycN4_2jInuKy6zbqQ&r=hFjA8A8KwwhQx5qilpfIleTL0XYVr_fckT8DnwIEWlQ&m=fgPmqux2N1LODT1cufk_CJiAKTZhRHIqK_n9LouQzTo&s=kUPAtZyNn31QnhDsOVyKJMJGsHpEG9CEKV8lyxPkMS8&e=> It would be helpful if some people on this group could attempt to answer these questions: 1. What are the most important things we know about solar geoengineering? 2. What are the most important things we don't know about solar geoengineering? I would appreciate it if you could put your answers in the form of bullet points and not write essays. It would also help if you could cite a key relevant paper or two.
