I agree with this research proposal but I'd be lying if I didn't say using this as a strategy moving forward to mitigate climate change didn't absolutely terrify me.
The best and only way I agree with this is some sort of maneuverable lagrange-point satellite mirror. That way if we find we are totally fucking the environment we can reverse it immediately.
Yeah, Lagrange point satellite definitely feels like the only removable option that would be safe... And even that seems like it would be contentious. (How do you decide when to reduce sunlight for what countries)
Also agree with all of the comments, that this is really just a way for us to continue our current trajectory.
Anything short of this in the "upper atmosphere" feels like an absolute non-starter, and this even feels like a non-starter as it is...
