That's not correct. The oceans are not nearly saturated, and they're
gaining CO2, not losing it.

Roman farmers had three type of tools:

- Tools without a voice (like ploughs)
- Tools with a voice they did not understand (like oxen)
- Tools with a voice without the right to speak (like slaves)

Now translate this to the real world where a right wing politician is
discussing global warming. There are three types of information:

- Information without a voice (newspapers, articles and reports)
- Information with a voice he doesn't understand (scientists)
- Information with a voice without a right to speak (voters)

You see, the world has not changed in 2000 years.

Do you mean that the variation with temperature of the partial pressure
of CO2 changed over the last 6 years ?

What is sure is that increasing ocean temperature cause a release of CO2
in atmosphere. As ocean have a great thermal inertia. The lag between
temperature increases and CO2 increases seems to be of the order of 800
years.
As we can not cool the oceans, there is nothing that can be done to curb
this increase in CO2 concentration.
And much more, as you could calculate by yourself with the IR absorbtion
spectrum, the Beeer-Lambert law and the Stefan-Boltzman law, even in the
worst case, CO2 cannot cause more than a less than 1K temperature
increase.

Trying to curb the increase of the atmospherical concentration of CO2 is
costly, useless and will divert humanity from more important goals.

During a period of warming oceans, the partial pressure of CO2 is
increasing.
That does not prevent oceans from absorbing CO2 because it precipitates.

Quote :
"Furthermore, this carbonate buffer is not the only buffer active in the
atmosphere / hydrosphere / lithosphere system. The Earth has a set of
other buffering mineral reactions. The geochemical equilibrium system
anorthite CaAl2Si2O8 - kaolinite Al2Si2O5(OH)4 has by the pH of ocean
water a buffer capacity which is thousand times larger than a 0.001 M
carbonate solution (Stumm & Morgan, 1970). In addition we have clay
mineral buffers, and a calcium silicate + CO2 <-> calcium carbonate +
SiO2 buffer (MacIntyre, 1970; Krauskopf, 1979). These buffers all act as
a "security net" under the most important buffer: CO2 (g) <-> HCO3- (aq)
<-> CaCO3 (s). All together these buffers give in principle an infinite
buffer capacity (Stumm & Morgan, 1970)."

I know 1970 is 39 years ago. But that part of mineral chemistry is still
valid nowadays.
