Putting dust or microspheres or sulphuric aerosols into the stratosphere to cool the planet is already being tested by scientists who claim they can "geoengineer" the planet to counteract global warming.
Coming soon to a sky near you.....
BS. SO2 has to be injected above 30 km in the stratosphere in the tropics in order for the Brewer-Dobson circulation and Rossby wave mixing in the "surf zone" to spread it horizontally towards the poles. Based on the Pinatubo signal, around 10 million tons per year need to be injected. If the SO2 is introduced at lower altitudes it will be flushed too fast into the troposphere and removed by wet scavenging. No jet can fly at 30 km. Only specialized planes such as the U-2 can fly at 22 km but not higher. The rapidly attenuating air density messes up air-foil boundary layer behaviour.
All the talk about planes, towers and cannons to deliver the SO2 is nothing but vapid bunk. The use of giant dirigibles is more plausible. Supposedly some designs would be able to carry 500 tons of payload. Assuming one trip per day we need 10,000,000/(365*500) = 55 of them. But none of the proposed designs would be able to reach 30 km since they are rigid or semi-rigid. Only true balloons can expand with altitude to reach about 35 km:

This geo-engineering crap made a flash in the publications several years ago and is now in the hands of governments and assorted other shysters.
