The geoengineering scheme, known as stratospheric aerosol injection, would not be cheap, but scientists say it could buy us some time until we reach net-zero carbon.
Not quite minuscule, for every ton of jet fuel burned, 2 tons of oxygen is needed, to take that in, about 3-4 ton of atmospheric air goes through the combustion, the volume of that air is quite a lot, and is only sustained because oxygen is constantly renewed. The diamonds will not have self sustained renewal and will be burned up pretty quickly.
Also being an aerosol increases surface and potential chemical reactions by a magnitude of maybe a billion per unit, so although we consider diamonds to be very stable in their normal form, a diamond aerosol is obviously much less so, and UV light refracted could accelerate break down of the diamond aerosol, into free carbon, which will create carbon gasses. I bet researchers have considered this, but I see no numbers for it?
