Old saying: It is one thing to keep an open mind, quite another to let your brains fly out altogether...
When you start questioning the laws of physics and chemistry, just because YOU do not understand them, then this becomes a farce.
Most of the oceans consist of deep water, with turnover times of hundreds of years. Comparing the surface temperature and CO2 saturation levels, with the great bulk of the ocean is not a valid comparison.
I can't begin to go into detail (and I am not an oceanographer), but I suggest reading some basic articles in Wikipedia:
https://en.wikipedia.org/wiki/Oceanic_carbon_cycle
I am not challenging the laws of physics and the oceanic carbon cycle at all. or questioning them. I am questioning whether the CC scientists ARE using the theory and the data correctly. I know pretty much enough about it.
No, my statements are about writing off the paper in OPs post without first seeing exactly WHAT the authors were referring to. The paper presumably (we don't know because ref 6 is yet to be published) deals ONLY with the 92/90 transfer between the atmosphere and the oceans.
The above is the diagram used in AR 1 to explain the Oceanic carbon cycle in 1990 in the AR 1. Notice then the numbers used to show the flows between the atmosphere and the oceans, 92 unit Into the oceans and 90 units OUT of the oceans. Two rather very close numbers would you agree? and, at that stage of the CC debate. See the units that were used for fossil fuels at the time just for perspective.
5 units into the atmosphere from fossil fuels versus a net 2 units out of the atmosphere into the oceans. In real terms a flow of 92 units out of the atmosphere into the oceans.
Give me a chance and I will show what AR 2, 3, 4 also say about this cycle.
It goes as far back as AR 1 where the very first statements were made on this carbon cycle in the form of a rather superficial description of the cycle accompanied by a picture (see above). As you quite rightly point out, almost 20 years later a lot more is known about the complexities of that cycle.
I will have a look at your link.
edit:/wow! Wikipedia uses the IPC as its reference! Amazing. A fancy version of the same diagram first published by the IPCC in AR 1 dolled up and in colour!

Makes you think does it not.
Edit 2:/ Imagine that. The Wikipedia article talks about Henry's Law! Now there's a thing. I must be a genius. Because I actually understand the basis of the process without ever reading the wiki link until you posted it.

(Aside, we were taught the Gas laws INCLUDING Henry's Law in Matric Physics in standard 9 and 10 in 1966/67).
Come on Gordon, there is no need to make this personal and attack other's the way you are doing. We are MyBB friends after all.
