I think it depends on how much you think climate change’s temperature increase will negatively affect the world. Since it’s impossible to reverse the predicted temperature change through behavior, if you want to limit or reverse the temperature change then stuff like geoengineering is the only way to limit temperature change while the world takes a century or two to go from industrial to renewable. If the idea is to make everyone suffer for their sins, or fantasize about Armageddon, then we can prohibit all geoengineering. There are difficult trade offs and stuff like changing the atmosphere to cool down has negative effects as well. But it may be better than 3 degrees warmer in 2100. I think these ideas have been explored, pretty realistically, in recent sci-fi books by Neal Stephenson and Kim Stanley Robinson.
