I believe I read somewhere that SO2 in low atmosphere leads to acid rainand other unwanted outcomes... But if released high in the atmosphere (ie deliberately using eg high altitude balloons) we can get the global cooling benefit without the negative effects.
Stratospheric aerosol injection using balloons.. A company named Make Sunsets does this and claim it counters CO2 emissions. They compare it to what happens after a volcanic eruption. High atmosphere SO2 different than ship SO2 emissions.
I bought a credit for $15, mitigating one ton of CO2 for a year. I don't have a strong belief in very costly warming, but I do in cost effective policy
IMO2020 - instead of switching to low sulfur fuel ships installed stack scrubbers to remove the sulfur and meet the new standard.. Cleaner air but it caused ocean pollution as the scrubbers discharged to the ocean. And the reduction in sulfur in the atmosphere increased global warming. Sigh! Side note: I once was told that most of the crude oil from Venezuela was high in sulfur.
As I read this post, cleaning the air accelerates global warming that is caused by increased CO2. To me that's not an argument to stop worrying about increased CO2.

Excellent and timely article. I remember reading about it around 1999 in Scientific American from Michael Mann. It's not news to science.
What action do Cox and Marchant, and you--recommend?
I, of course recommend accelerating funding for ocean iron fertilization--the fastest proven way to remove 1000 Gt of CO2 and cool the planet.
