Nanoparticles in the atmosphere affect the energy balance of the earth. In general, it is known that they have a cooling effect on the atmosphere near the surface of the earth. Therefore, we are now focusing on the cooling effect by considering artificially formed nanoparticle layer which are dispersed in the atmosphere so that we can control global warming. In this study, the feasibility of global warming control by dispersing nanoparticles in the atmosphere is examined. The equivalent temperature decrease by nanoparticle layers is converted to a reduction of CO_2, and this CO_2 reduction is compared with the CO_2 output required to form the nanoparticle layers in the atmosphere. The reduction of CO_2 equivalent to temperature decrease due to nanoparticle dispersion is very large compared with the CO_2 output due to the object launch. Therefore, it is inferred that this method presents a feasible solution to the global warming problem.
