For from its air-contacting surface to its depths thousands of meters below, the World Ocean has captured 93.4% of the total heat forcing humans have already unleashed. The remainder is almost evenly divided between the atmosphere, the continents, and the ice.

We rely on floats and deep-plunging sensors to keep track of total ocean heat content. But on any given day we can see well enough what is happening at the surface.
