We ought to stop surface-level sulfur emissions, for human health and also because ship engines that produce sulfur also produce lots of other nasty shit. Stratospheric sulfur is much more efficient, per kg, at reflecting sunlight, so we could replace the cooling effect of surface-level sulfur with stratospheric sulfur, and if we choose to, go even further to cool the planet more.
