Maybe it's a reasonable hypothesis. Another reasonable hypothesis would be a slowdown in ocean convection. Another would be cloud cover changes. These are all surface ocean measurements, yes? Do we even have seafloor temperature monitoring stations? I know there are mobile bouys that circulate underwater, but these aren't the temperatures in these graphs, yes? What do temperature changes look like around known submarine volcanoes?
