If CO2 Levels in Atmosphere & in Oceans are assumed to be in Equilibrium; then, the respective fraction of ‘CO2 in Atmosphere’ & ‘CO2 in Oceans’ is a function of ‘Temperature’: Is it Earth’s Temperature or Ocean’s Temperature?
Does Earth’s Temperature drive Ocean’s Temperature?
If so, does Ocean’s Temperature drive CO2?
OR
Does CO2 (emission from Ocean) drive Ocean’s Temperature; and in turn, the Earth’s Temperature?
OR
Does CO2 (emission from T-Earth) drive Earth’s Temperature; and in turn, the Ocean’s Temperature?
What exactly it means, when the concentrations of CO2 both ‘in the atmosphere’ & ‘in the Oceans’ increase simultaneously?
Assumptions so far:
Role of water-vapor as the largest contributor of the Earth's Greenhouse Gas Effect has been ignored from this discussion as water vapor does not directly control Earth's Temperature . It is the addition of CO2 that subsequently increases the Earth's Temperature; and in turn, leads to an increase in water vapor that further increases the Earth's Temperature.
In terse, the answer is, yes the Earth’s Temperature drive Ocean’s Temperature. Besides, there are facts and scientific evidence which reveals that ocean temperature drive CO2 as well.
Most of the world’s carbon resides in the ocean, and the processes that result in exchanges between the surface ocean and the atmosphere, and between the upper ocean and the deep ocean, are critical. Carbonate chemistry regulates much of the transfer between these systems, but biological processes, such as photosynthesis which turns CO2 into organic material, also play an important role. Settling of this organic carbon into the deep ocean is known as the “biological pump.” Note that the upper ocean has lower concentrations of total carbon than the deep ocean as a result of the actions of this pump. With the ocean’s circulation pattern disruption, there can be chances that Ocean could become a source rather than a sink for carbon.

Dear Suresh,
Please note that
- CO2 is more or less continuously released into the atmosphere by a variety of biogeophysical processes such as fossil fuel burning, biomass burning, and respiration (from plants as well as animals), and these processes are highly variable in space and time.
- Similarly, there are geochemical processes that transfer atmospheric CO2 to the oceans or to the biosphere, and both the solubility of that gas in water, as well as the efficiency of photosynthesis in plants are functions of temperature (of the water in the first case, and of the canopy in the second), and those processes take place at different locations and times that those mentioned in the previous bullet.
- Temperature itself varies wildly over many spatial and temporal scales, so all these processes interact continuously. For instance, CO2 may be absorbed in the colder parts of the ocean, and released in warmer waters, and the extent and depth of those oceanic areas keep changing as a result of oceanic currents.
- The role of water vapor in the radiation balance in the atmosphere, and hence in the climate system, has been well known for decades and is included in all modern climate simulations: if you search the Internet for publications on that topic, you will collect relevant references dating back many decades ago.
Hence, an assumption of "equilibrium" is inappropriate when discussing the climate of the Earth. What we observe is the combined result of many interacting factors, which operate on many different spatial and temporal scales. It is not reasonable to assign a single cause to a particular change: the planet is a complex system, and its evolution results from the complex interactions between a wide variety of processes.
Best regards, Michel.
Dear Suresh,
the answer is included in the presentation of prof. Murry Salby for example in Hamburg: https://www.youtube.com/watch?v=2ROw_cDKwc0
or in the short version here: https://www.youtube.com/watch?v=nFPP3RlycB8
Both answers are "yes". The Earth’s Temperature drive Ocean’s Temperature and the ocean temperature drives concentration of CO2 in the atmosphere. But, the primary parameter is TSI, which drives the ocean temperature in the same way as the temperature of atmosphere:
