I am not sold CO2 is causing the warming anymore. CO2 is heavy and so falls to the ground if cool. Adding more trees and vegetation on the ground near cool areas should do the trick.
Methane is probably more of a contributor. And blocking the sun is not a real solution. It has the potential for catastrophic changes like less vegetation.
Plus there are studies on global dimming. More pollution leads to global dimming which leads to less evaporation which leads to less clouds cover.
As a matter of fact, global dimming is better studied and should be a topic before conducting this research
