As the area / volume ratio for the NH parts of the oceans is practically the same as for the SH, the surface heating (W / m2) must be larger in the NH parts, within the constraints of heat exchange via ocean and air currents (and partly by the difference in warming area in the tropics vs. the cooling areas in the higher latitudes)...
You can even go one better — if you ignore the fact that there are negative forcings in the system as well (cheifly aerosols and land use changes), the forcing from all the warming effects is larger still (~ 2.6 W / m2), and so the implied sensitivity even smaller!
That is the largest human induced cooling factor, some 1 W / m2 against the 2.4 W / m2 warming by GHGs since the start of the industrial revolution.
The size of the imbalance varies with the time span you consider, because it is larger in periods of weak surface warming such as the last decade, when 0.9 W / m2 pertains, but smaller over longer periods that have more warming at the surface such as the last 20 - 30 years.
Look on the bright side — it could be much larger excess than 0.5 W / m2 and it had better be because 0.5 W / m2 is only enough to warm the basin by 0.2 C in the next 100 years.
It is my position that the imbalance was larger before Y2K and what we are seeing > 700m is simply a pulse of warming well above 0.5 W / m2 during the 1990's propogating into deep water.
