As this post makes clear, higher temperatures lead to more CO2 because warmer water
outgasses more.
So how, with those uncertainties in the movement rates, are you still 100 % certain that — for example — the deep sea clathrates are not
outgassing more CO2 because of a current warmed 800 years ago during the MWP?

«We've got a spacecraft on the way to Ceres, so we don't have to wait long before getting
more context on this intriguing result, right from the source itself,» said Carol Raymond, the deputy principal investigator for Dawn at NASA's Jet Propulsion Laboratory in Pasadena, Calif. «Dawn will map the geology and chemistry of the surface in high resolution, revealing the processes that drive the
outgassing activity.»
Faster sea floor spreading, presumably associated with
more volcanic activity at subduction zones, and / or other increases in volcanic activity or geologic
outgassing, or faster oxidation of exposed fossil organic C (as in shales)-- greater geologic CO2 emissions (I think another way of looking at the inorganic part is that any given region of sea floor has less time to accumulate carbonate minerals from chemical weathering, so that C reservoir could shrink while others, including the atmosphere, can grow).
More important, my analysis earlier strongly suggests that the
outgassing is caused by ocean temparature only, and not by land temperature.
On longer term, this effect is countered by the increase of CO2 in the atmosphere:
more CO2 in the atmosphere means a higher pCO2, thus a smaller difference in pCO2 over the warm oceans, thus reducing the
outgassing of CO2.
The likely candidates are
outgassing from warming ocean waters...» Actually,
more CO2 is being desolved into the ocean due the the sharply raised levels.
Assuming that about 98 % has absorbed by the oceans (153ppmv) and assuming that the oceans have released about 120ppmv since 1850 due to warming, then PCO2 (aq) would have still increased, because proportionately
more CO2 has been absorbed by the oceans than has been
outgassed.
It is also
more like a rate - law associated with an
outgassing effect, where the CO2 concentration should be the convolution of the Temperature with an
outgassing CO2 impulse response.
Cooler seas, less
outgassing,
more co2 absorbed, soon it'll be global cooling causes ocean acidification; — RRB - Can't wait for that one.....
It DOES N'T take any net CO2
outgassing from the oceans in the case that the atmospheric CO2 growth is caused to a significant degree by warming climatic factors — there's
MORE than enough human input to achieve the equilibrium between ocean and atmosphere.
I calculate Delta GT carbon = 6.5 * Delta T + 0.48 * emitted carbon, which I make to convert to 2.8 ppmv per degree C. That's much less than your figure, but given the timescales one would expect much
more outgassing over a longer period because a greater quantity of water will warm.
And if warming oceans are supposed to be nett
outgassing carbon dioxide, how do they absorb
more and become less alkaline?
I don't need to explain it for my Model to remain valid.The concept of ocean
outgassing in response to
more sunlight is a useful add on but not an integral component because I do not ascribe significant climate forcing to that CO2.
Winds quickly drive CO2 away from the sunny regions where it is being released so it is easy to envisage Henry's Law applying in a particular location but if the CO2 rich air is being constantly removed then
more outgassing can then occur in the same region and it is not hard to envisage an accumulation of CO2 downwind or over land masses where the wind flow slows down.
MORE c02
outgassed from the ocean.
Over geologic time, volcanoes and mantle
outgassing have emitted
more CO2 than humanity ever will, but that's over the course of 4.5 billion years.
The total temperature increase 1959 - 2004 was 0.6 °C, thus only 1.8 ppmv is caused by
more ocean
outgassing, the rest is from anthro emissions...
However, the synthetic fibre industry has made strides both in producing the product
more responsibly at the factory level, and reducing
outgassing.
