Some heat is being transferred to the deeper
ocean by wind changes, reducing the rate of increase in the
upper layer, which reduces the warming rate on land.
Their argument goes like this: It is not possible that warming of the deep
ocean accelerates at the same time as warming of the
upper ocean slows down, because the heat must pass through the
upper layer to reach the depths.
Second, physically there is absolutely no problem for wind changes to cool the
upper ocean at the same time as they warm the deeper
layers.
That the heat absorption of the
ocean as a whole (at least to 2000 m) has not significantly slowed makes it clear that the reduced warming of the
upper layer is not (at least not much) due to decreasing heating from above, but rather mostly due to greater heat loss to lower down: through the 700 m level, from the
upper to the lower
layer.
(1) The «fast response» component of the climate system, consisting of the atmosphere coupled to a mixed
layer upper ocean, has very little natural variability on the decadal and longer time scale.
Thus, some heat gets converted to kinetic energy, but that gets converted back to heat, either by viscosity or by thermally - indirect circulations that produce APE while pulling heat downward in the process (LHSO: Ferrel cell (driven by extratropical storm track activity), Planetary - scale overturning in the stratosphere and mesosphere (includes Brewer - Dobson circulation (I'm not sure if the whole thing is the Brewer - Dobson circulation or if only part of it is)-RRB-, some motions in the
ocean; LVO: wind driven mixing of the boundary
layer and of the
upper ocean (though mixing itself tends to destroy the APE that the kinetic energy would create by forcing heat downward)-RRB-.
Given that the other important variables (sea surface temps, depth of the warm
layer, and atmospheric moisture) are all predicted to increase, it seems hard to make the claim that tropical cyclones will be unchanged, just as it seemed unwise to claim that Lyman et al's «Recent cooling of the

In colder

upper and deeper
layers (as well as nutrients, when phytoplankton decomposes).
Relative to the entire depth,

Thus, if the absorption of the infrared emission from atmospheric greenhouse gases reduces the gradient through the skin

upper oceanic
layer by the absorption of sunlight to remain there to increase water temperature.
