The estimated increase of observed global

So the mechanism should cause a decline in skin temperature gradients with increased cloud cover (more downward
heat radiation), and there should also be a decline in the difference
between cool skin layer and
ocean bulk temperatures - as less
heat escapes the
ocean under increased atmospheric warming.
Increased warming of the cool skin layer (via increased greenhouse gases) lowers its temperature gradient (that is the temperature difference
between the top and bottom of the layer), and this reduces the rate at which
heat flows out of the
ocean to the atmosphere.
ENSO events, for example, can warm or cool
ocean surface temperatures through exchange of
heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).
