I think geo-engineering will open Pandora's box. On one hand, we need to invest in geo-engineering as a last resort, on the other hand, if people see this as the last resort the problem of CO2 will seem less urgent. Very dangerous stuff.
People already don’t care about carbon emissions. Those on the right think it’s a hoax or humans aren’t causing climate change, those on the left largely pay lip service, but still do very little.
