I thought tropospheric S02 caused acid rain. The stratospheric SO2 is bound to migrate down to the troposphere (Sulphur compounds are heavier than air: there's nowhere for them to go but down).

The "most efficient" implementation of this idea is to burn coal, capture the exhaust, separate the SO2, release the CO2, and inject the SO2 into the stratosphere. The dirtier the coal the more sulphur it has so the better it compensates for its CO2. Toxic, I'd say.

But I have to agree that these things need to be discussed candidly and that the ideologically driven dynamics in the scientific literature that you mention are indeed toxic.
