To be clear, I'm absolutely not promoting increased sulphur emissions as a solution to our climate problems. Moreso pointing out that all those emissions are potentially masking the true severity of our current predicament.
I recall there was a major push against Acid Rain in the 70s-90s. If SO2 emissions were effectively regulated in that period (easy to do because “acid” is scary) then what magnitude of impact did that have on our post-90s warming?
