My stated point was acid raid in the context of climate engineering, there was nothing said about quantity. Small quantities will cause acid rain in undetectable amounts, and have the same nil effect on climate, but presumably the end goal is to have a measurable effect on climate.

Since we already have SO2-induced acid rain on a warming planet, and there is no real motive to believe such intentional releases will be confined to the upper layers of the atmosphere, it follows that such climate engineering attempts will have a measurable effect on acid rain.

So the point is perfectly valid even if you won't follow it through to the logical conclusion. Just like these clowns here.
