... but not in the desired direction. Sulfur dioxide emissions from shipping appear to have actually been slowing (!!) global warming by seeding clouds which reflected sunlight.
Sure, but a single bus would emit way less than the 60-150 cars (yes, large buses here have a total capacity of about 150 people [1]) it replaces. And if you have a bikable city like about every city in the Netherlands is, there's zero emissions.

We do, but even there there is progress! In fact, the regulations on sulphur content going into effect showed that this actually had climate impacts on the scale of an ultra-large geoengineering project [2]. On top of that, bunker fuel is banned in many countries' 12-mile-zone or at the very least near ports, ships have to burn diesel there.
