Interestingly, that used to be true, but in the past few years some regulations have gone into effect regarding sulfur emissions in cargo ships.
I think that was probably a good thing in the long run, but there's some evidence that the sulfur particulate matter was "hiding" some of the warming we "should" have been seeing based on our CO2 emissions, because global warming has spiked a bit as sulfur has decreased.
