These rising atmospheric greenhouse gas concentrations have led to an increase in global average temperatures of ~ 0.2 °C decade — 1, much of which has been absorbed by the oceans, whilst the oceanic uptake of atmospheric CO2 has led to major changes in surface ocean pH (Levitus et al., 2000, 2005; Feely et al., 2008; Hoegh - Guldberg and Bruno, 2010; Mora et al., 2013; Roemmich et al., 2015).

In the case of warming caused by a disproportionate increase in atmospheric CO2 (compared with oceanic CO2), an increase in temperatures only slows down the rate at which CO2 is absorbed by the oceans.
Source: Lyman 2010 The reaction of the oceans to climate change are some of the most profound across the entire environment, including disruption of the ocean food chain through chemical changes caused by CO2, the ability of the sea to absorb CO2 being limited by temperature increases, (and the potential to expel sequestered CO2 back into the atmosphere as the water gets hotter), sea - level rise due to thermal expansion, and the amount of water vapour in the atmosphere.

In 2005, during the hottest average decade on record, 8 low - wind conditions known as «the doldrums» combined with very high ocean temperatures to cause massive coral bleaching in the Virgin Islands.9 This was followed by a particularly severe outbreak of at least five coral diseases in the Virgin Islands, resulting in a decline in coral cover of about 60 percent.9 There is some indication that higher ocean temperatures — between 86 and 95 degrees Fahrenheit (30 to 35 degrees Celsius)-- promote optimal growth of several coral pathogens.9 Other research showed that elkhorn coral post-bleaching had larger disease lesions than unbleached specimens, suggesting that bleaching may increase the corals» susceptibility to disease.9, 10
I agree that longer term processes as well as in the oceans as in the biosphere have their influence, but these too are limited: once the temperature of the full ocean (including the deep oceans) is increased by a certain temperature, the related increase of CO2 in the atmosphere will hinder a further increase of CO2 from the oceans.
So the CO2 we see is clearly anthropogenic, however the rate of increase is greatly affected by the biosphere, and by the temperature, especially the ocean temperature.
Here's a clue — a tendency toward a more frequent La Nina state, driven specifically by increasing GH gas concentrations (and similar to conditions in the mid-Pliocene), may provide some modulation of tropospheric temperature spikes, but that energy will be advected somewhere (the idea of homogenous dispersion throughout the ocean is absurd), and that somewhere is exactly where we are seeing the biggest changes in the climate right now — the Arctic.
Using an ocean circulation model for the shelf, the authors find that surface temperatures may increase by 0.5 to 2.0 °C, seasonal surface salinity may drop by up to 2 PSS in some areas, and that Haida Eddies will strengthen, as will the Vancouver Island Coastal Current and freshwater discharges into coastal waters.
Whether we look at the steady increase in global temperature; the buildup of greenhouse gases in the atmosphere to the highest level in a half - million years; the march of warmest - ever years (9 of the10 hottest on record have occurred since 2000); the dramatic shrinking of mountain glaciers and Arctic sea ice; the accelerating rise in sea level; or the acidification of our oceans; the tale told by the evidence is consistent and it is compelling.
I'm a phsycist - and I remember being highly skeptical about AGW when I first heard about it in the late 80's - reasoning that the ocean was such an enormous heat sink that any impact on atmospheric temperatures would be dwarfed by the impact on increased heat content in the ocean.
If all came from the oceans (which is likely with increased temperatures), this would give an increase of the d13C level by 1.6 per mil in the atmosphere.

Coby, if the earth is warming as a result of increased periodic solar activity (or some other more complex reason) as suggested by the long term cycles mentioned above measured before man was on earth or industrialized, is it posssible that the observed increases in CO2 in the atmosphere are simply coming from warmer oceans, since liquids can not hold as much gas at a higher temperature than they can at lower temperature?
In fact it is a very risky target for all of us: so far, temperatures have increased by just.8 degree Celsius and we are already experiencing many alarming impacts, including the unprecedented melting of the Greenland ice sheet in the summer of 2012 and the acidification of oceans far more rapidly than expected.
