First of all, the SO2 goes into the stratosphere, not the atmosphere.

We know a lot about it because volcanoes do this occasionally. Temperatures cool down for about 2 years, which is how long it takes for the S02 to break down.

Considering that the stratosphere is part of the atmosphere, that's both pedantic and incorrect.

Volcano's don't pump pure SO2. Yes, the science may be entirely valid, and it's not for me decide, but I think it warrants heavy consideration before we try to solve problems we're creating due to adding excess by adding additional excess.

The distinction is important because at lower altitudes SO2 produces acid rain. But the stratosphere is far above the rain clouds.

Clarifying what part of the atmosphere is important, sure, to say it's not in the atmosphere and instead in the stratosphere is absolutely wrong.

Doesn't SO2 sink in air? Because we'll need to be constantly adding it to the atmosphere aren't we going to end up with acid rain as it falls to the ground?

>>Sketch+UU2
My impression is that there is some leakage, but very small compared to the acid rain problems of the past.

Either way, if acid rain is the price for controlling global warming, I think that is a very desirable trade-off!
