I saw an article about this last week. It identified the cause as a new rule last year switching the fuel for cargo ships and tankers that reduced the allowed sulfur content by about 80%. This is very good to slow ocean acidification, save algae and coral. But the sulfur in the air reflects or scatters sunlight away from the earth and the surface of the sea. Go figure.

Almost at the bottom it gets around to this: Which says: "Here’s where things get esoteric. As of January 1, 2020, the International Maritime Organization (IMO) put a limit on the sulfur content in shipping fuels, reducing the global upper limit on sulfur content from 3.50% to 0.50%. This policy is referred to as IMO 2020. Here is a link to an article describing this change. This reduced limit was mandatory and led to over a 75% drop in the emission of sulfur oxides. While great for the environment in many respects (e.g. less acid rain and ocean acidification), there was also a not-so-unexpected consequence." A little more explanation and discussion of some other possibly contributing factors follow what I quote above. BTW, bostonwalker, you owe me, but I'll try to return the favoe at my earliest convenience. It took me at least a half hour of digging through my history to find TFA. If I had a link, I would have included it. And, BTW, it would have been OK to list me as a source on your doctoral dissertation. Although I am getting old and have a hard time remembering, I am widely known to be very reliable, particularly when I'm right.
