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

warming area in the tropics vs. the cooling
areas in the higher latitudes)...
Even if there is equal
warming in the tropics, but the heat is not dissipated to the poles fast enough by the
ocean currents, the
