There's been some talk about ship emissions changing and created more global warming because some of the chemicals they pumped actually had a cooling effect. I can't remember the specifics, but was there ever a reason why we couldn't just pump out cooling agents into the atmosphere?
Given the choice - and I'm sincerely asking this, because I don't know enough about the subject - what'd be worse here, the disease or the cure? Could we live with acid rain if it staved off cataclysmic global warming?
If the goal is to conduct intentional geoengineering to reduce global warming, there are better things to inject into the atmosphere than sulfur dioxide. Basically just reflective dust.
