That's what they think, based on their CFD models. Before reading this I was thinking that, since warming has increased overall liquid sea-water volume globally, more CO2 was being dissolved in the sea or something, and that's why despite higher emissions more of it was being dissolved into the sea than going into the atmosphere. But then there is only so much you can dissolve, and that's why the last ten years of minimal warming is just a plateau.
