Solar shading with airborne particles is not a good solution to global warming because it does not have a large enough impact to influence global warming. In order to be considered as a good solution to global warming the solution needs to be effective. In my opinion this would not be effective at all.
No, solar shading with airborne particles is not a good solution to global warming, because humans are small and insignificant compared to the atmosphere. It is futile for humans, small as they are, to think they can control the atmosphere or the universe. Humans will never be able to control the earth and the weather on a large scale. Any attempt to manipulate the atmosphere will cause more harm than good.
