As temperatures rise today, most of the heat is being taken up by the surface layers of the oceans.
As a result of this, more of the CO2 bound in organic matter remains in the surface layer, which reduces the ocean's potential to take up atmospheric CO2.»
Stuck to their calcium carbonate platelets, organic matter sinks to the ocean floor — allowing surface layers to take up a new carbon dioxide from the atmosphere and process it.
Balance time for those surface layers is short, but for the deep ocean, CO2 doesn't diffuse but is gradually carried there by slow moving ocean currents, these may take on the order of a thousand years to complete.
I'd like to ask a general question: since the oceans are taking up about 1/3 of the anthropogenic carbon emissions, what is the opinion now of the scientific community about when the ocean surface layers will get saturated and this carbon sink (on relatively short timescales) will start to diminish?
Whether the ocean surface warms more than that is totally dependent on how long it takes excess surface layer energy to be diluted into the entire basin.
It takes about 1.5 years to bring the oceans surface layer in equilibrium with the atmosphere.
When the ocean surface is cooler, warmth is taken from the surface into deeper ocean layers that «do not emit heat out of the planet».
Either this is a truism (the sun must be heating the ocean surface first) or it is meant to take into account the complex circulations that occur in the ocean, like the Gulf Stream's involvement in a vertical rise of waters from deep ocean layers in one region and sinking of the cooled surface waters as the stream reaches its northern limit.
Of course, if the air were to be warmer than the ocean surface then evaporation would take the extra energy required from the air rather than the water and that 1 mm deep layer (0.3 C cooler than the ocean bulk) would rise to the surface and dissipate but that doesn't happen often or for long.
