Large ocean vessels like cargo and cruise ships are some of the biggest greenhouse gas producers on the planet, so I really hope this is a good way forward.
At the very least they should have all long-since been converted to diesel instead of bunker fuel, which emits more carbon and a shit ton of sulfur, one of the worst greenhouse gasses. But these people give less than a fuck. Countries need to be willing to stop trade with vessels like this before even the simplest technical solutions will be adopted.
Sulfur polution actually has cooling effect, so it is kind of opposite of greenhouse gases. It sucks in different ways, though.
If in the upper atmosphere yes, but I doubt any of the sulfer from these gets anywhere near that height, and actually just falls back down to pollute down here.
It's actually been theorized that ships using cleaner fuel (read: less sulfur output) contributed to the peak temperatures of the atlantik ocean
Thankfully we already have non-sulfur cloud seeding technology so now that we know the oceanic clouds made it cooler we can make more clouds without sulfur, netting us the heat shield without the pollution.
No, the link seems to be real. Very recent studies based on satellite data have detected a reduction in cloud reflectivity caused by the reduction in sulfur emissions. This will accelerate global warming; by exactly how much is currently not known.
