I'll admit, I'm also skeptical about our ability to manage climate by pumping even more into the atmosphere. The CO2 models have been very accurate, but doubling the number of variables more-than-doubles the complexity. SO2, for example, is even more acidic than CO2, so we'd risk helping the temperature while making the oceans worse.
SO2's instability is somewhat reassuring, and I'm willing to consider a plan, especially if atmospheric scientists can come to a similar overwhelming consensus as they have on CO2. But until such a plan exists, I believe we need to focus heavily on decarbonization because that's a plan we are absolutely certain to be effective. To the extent that geoengineering reduces the urgency of that, it risks making things worse.
