At this point it seems like the game plan for the ultra wealthy is to make the earth uninhabitable for everyone but them.

Song says it appears that the world’s oceans are losing their ability to dissipate heat from the surface into the deep ocean.

But isn't it obvious that there's a limit how much heat the oceans can store? Actually it can only get rid of it by emitting it into the atmosphere/space.
Additionally the hotter the water gets the more energy it emits which should slow down the net energy absorption.
As those two effects are opposites of each other there should be an equilibrium temperature where they cancel each other out. Currently it seems the oceans are a bit away from that equilibrium. It should swing the other way in a few decades or so. The oceans are big that's why it takes time for change to manifest.

For me it sounds like the journalist didn't really understood, what Song researched or tried to make a click bait article.
