That's the only idea that was actually tested successfuly. Accidentally of course. There was a brief pause in global warming right before we banned sulfur from our fuels.
It's not that there was a brief pause prior, it's that after the ban temps started rising way more than expected. The fuels were "hiding" the extent if global warming.
Between the 40s and the 80s global temperatures pretty much oscillated around the same value when our sulfur emissions roughly balanced our carbon emissions. But due to local damage from acid rains we reduced sulfur emissions (or at least reduced their growth) and carbon emissions rose happily unrestricted.
