Form a socially legitimate coordination point for geoengineering safety that is very EA and nuanced and aware of cost-benefit and x-risk, and help reduce the risk of termination shock or Snowpiercer scenarios, focusing secondarily on such risks as acid rain and climatic shifts reducing agricultural throughput. This domain should stay out of the hands of reflexive Luddites and handwringing do-nothingists. It should help high-integrity geoengineering projects rather than just hurt them like anti-nuclear people ended up doing by over-regulating nuclear power, with an eye to being calibrated on how to steer geoengineering effectively.
