Sulfur aerosols: Would the acid rain significantly threaten mass extinctions via acid oceans?

[palmer]

The atmospheric sulfur would be high enough to mostly not precipitate. It's just an example anyway, once the models are adequate there will be plenty of ways to cool (or warm) the earth if that becomes necessary.

Sulfur aerosols: Would the acid rain significantly threaten mass extinctions via acid oceans?

Try calculating, on an order of magnitude basis, the mass of pure sulfuric acid that would be reqired to change the PH of the worlds oceans by even .001%.
