This is kind of a big deal — the long atmospheric lifetime of CO2 means that once started, people need to maintain the technical infrastructure for geoengineering for longer than civilizations last.

I have never seen a geoengineering that does not seem to have big possilbe side effects and cause a fair amount of its own co2 emmisions (constant flights or whatnot to renew). the only thing to me that seems maybe is the idea of a space shade which could be easily scrapped if side effects came up.
