Tropospheric so2 is a problem for reasons beyond warming.
Stratospheric so2 might not be a problem, but geoengineering is always risky.
Plus, since so2 is significantly more reactive than co2, it will be removed from the atmosphere more quickly, meaning that it can only act as a temporary mask without constant maintenance. All-in-all, it’s probably best to see how much damage we are doing early on before we find ourselves in the so2 equivalent of credit card debt and slowly poisoning ourselves to death trying to stay cool.
