"1) Trenberth MISLABELED it because ENERGY is not in W/m2.. Which is important in this discussion --- because being in a unit of power is INCAPABLE of relating to Heat ENERGY stored in the ocean or elsewhere."
The surface area of the Earth is constant. The surface area of the oceans and land masses is constant, for all practical purposes. W/m^2 is irradiance.
Because the surface area is constant, it doesn't matter if the calculations are done in units of irradiance first then multiplied by the surface area or multiplied by surface area before doing the calculations.
Addition is distributed. It is that simple
You missed the subtlety.. Power is in W/m2 (or just Watts for a point source).. If you're gonna store it and call it ENERGY, then it's not AREA that's the issue --- Its TIME.. Like in the difference between Watts and KWatt-Hrs ?? Got it?? That heat at ocean depth is in Joules -- Joules has a TIME component. 100 x 10^22 Joules could have gotten there from ANY amount of power depending on the RATE of storage.. Trenberth's heart was in the right place.. For something as big and complex as the Earth's Climate --- it's ENERGY that needs balancing.. But that's not what was in his diagram..
