For a body to have a constant temperature the energy input must equal the energy output.
The statement that an energy input over time will result in a given temperature increase ASSUMES that the energy output is constant. This assumption is NOT valid where ocean temperature is concerned.
The oceans are cooled by evaporation which is known to be variable and in itself creates a balance in controlling the energy input at the surface.

A huge problem for the scientists when assessing the geothermal input in terms of temperature measurement.

It is interesting that generally ocean temperatures rarely go above 35 C and this seems to be an overall equilibrium value about which nature hunts by a small percentage. I have no idea whether this is true in climate terms. Do we have figures on this?
For me this 35C figure may be explained by reference to the evaporation rate of water plotted against temperature where the trace rises sharply at around 25 C in an exponential manner. This results in the evaporation rate (cooling) eventually rising to balance any energy input (heating) at or around this 35 C value.

Where geothermal input is concerned we have little knowledge so it is understandable that a constant value is assigned; but is probably not true. First as there is movement of magma in climatic terms and secondly as the inputs vary considerably randomly both in location and time.
A third factor is that the tectonic movements involved in themselves can have a marked influence on eventual climate conditions and here we have very large energy values involved, quite apart from the mean rising flux of some 0.5 mW/sq.m.
