There is no surprise that the CO2 in the atmosphere winds up partially in the oceans, nor that the amount of CO2 going into or coming out of the oceans varies in time and space — that's simple equilibrium chemistry between the liquid (that is, dissolved) and gaseous phases, and does explain part of the variability about the long term rising trend.

Measurements of 13C / 12C on corals and sponges — whose carbonate shells reflect the ocean chemistry just as tree rings record the atmospheric chemistry — show that this decline began about the same time as in the atmosphere; that is, when human CO2 production began to accelerate in earnest.

Although the technologies are still nascent, the idea that humans might help remove carbon from the skies as well as put it there is a reasonable Anthropocene expectation; it wouldn't stop climate change any time soon, but it might shorten its lease, and reduce the changes in ocean chemistry that excess carbon brings about.

Therefore about half of mans CO2 goes into the atmosphere, nature has a slight protecting effect by absorbing the other half for us, but this is damaging the chemistry of the oceans.
