There's a good chance that the sudden bump in sea surface temperature is a consequence of us cleaning up marine diesel. Which is at least interesting, because it suggests we were doing geoengineering without even knowing it.
(Random thought: what's the sulphur content of automotive diesel? I know it's cleaner, but there are so many more cars than boats. Could we see another sea surface temperature bump as we phase out diesel cars?)
