Dear Charlotte and other colleagues,
Physical simulations are needed but do almost nothing to address the anxiety around solar geoengineering on environmental, geopolitical, and ethical grounds. Physical variables seem to be the only authoritative ones in the debate. At the same time, the justification for advocating solar geoengineering is often based on the idea that it should be used to prevent more human suffering. However, little is empirical about human suffering in how the discussion is conducted. Within that context, I would like to point out what Kyriacos Koupparis and Jesse Mason are doing at the UN World Food Programme on Anticipatory Action and Early Warning Systems. If I understand it properly (which is not granted), it seems it could offer a way to predict how climate interventions could affect not only agriculture but, most importantly, hunger. Perhaps the modeling that climate scientists are doing could be connected to those guys' modeling. I know that coupling the modeling of different systems is nothing new and it is very complicated. But looking at what Reflective is doing, in addition to showing what we already see in academic papers in a (bit) more user-friendly format, perhaps something more related to impacts other than the usual physical ones would be a real contribution.

This appears to be an efffort to develop a popular SAI simulator for “risk-risk” scenarios. I haven’t looked at it but it appears an excellent contribution to the effort to legitimize and urgently deploy other “Direct Climate Cooling” (DCC) (or “Geoengineering”) approaches (https://academic.oup.com/oocc/article/4/1/kgae014/7731760 ) And: <https://academic.oup.com/oocc/article/4/1/kgae008/7706251> https://academic.oup.com/oocc/article/4/1/kgae008/7706251 Ideally down the road such a simulator would also include other (possibly complementary) DCC and Short-Term Climate-Driver (STCD) (like methane and black carbon emissions reductions) approaches. But good start (and also happy to collaborate) Reflective!

In the name of one of Reflective's principles (Global engagement), I strongly suggest that you also create a mobile optimized site for the simulator, since more people have a computer in their pocket, and can't afford a large screen to play with the sliders. Happy to collaborate (another Reflective principle). <Screenshot 2024-11-22 at 9.52.58 AM.png> On Tue, Nov 19, 2024 at 12:58 PM Charlotte DeWald <[email protected] <mailto:[email protected]> > wrote: Dear geoengineering community, Excited to introduce Reflective <https://reflective.org> , a philanthropy-funded initiative focused on SAI research and tech. We are now launching an SAI simulator <https://reflective-fe.vercel.app/?ssp_scenario=SSP2-4.5&temp_target=1.5&spatial_agg=WGI+Reference&decade_visualization=2091-2100&start_year=2035&ramp_up=10&var=tas> to enable policymakers, the media and public to explore regional effects of various SAI deployment scenarios as compared to the impacts of continued warming. We welcome your feedback as we plan for future iterations.
