As a scientist you will be aware that the devil is the in the detail. SO2 contributes to aerosol formation which can either warm (through absorption of solar radiation on dark particles) or cool (from forming cloud droplets and reflecting radiation) the atmosphere. SO2 emissions at ground level are usually classified as indirect contributors of warming The article you posted talked about SO2 in the stratosphere - where cloud formation occurs. Cruise ships typically operate at sea level.
