Wharfie, as the oceans warm, they'll hold less CO2, it's true. But there isn't much sign of them warming so far. Nor is there a significant change expected any time soon. Maybe 3 degrees here and there, maybe, in a decade or three.
2GT/year into the ocean is a fast rate considering we are only achieving something like 7GT/year into the atmosphere.
There is a LOT of calcium being washed into the oceans and a LOT of shells being made and a lot of neutralizing of carbonic acid to be done. Imagine how yummy diatoms and other beasties with flimsy shells will be to the food chain.

That's where it goes. Onto the ocean floor. Kilometres deep. Trundling along to subduction zones, back into the oil-production cooker and volcano propellor.
Oceans can take all we can provide. The oceans were starved of CO2 until we came along. Plants on land were grabbing nearly all of it, leaving a famine for the fish.
Now, ironically, that there is lots going into the ocean, the fish have been depleted by sophisticated hunting and huge drag nets.
Aquaculture is a good thing. But it's hard work to get past government [in New Zealand anyway].
Governments STOP people doing good things and support bad things [such as government officials flying around the world to study CO2 emissions as a problem - including from aircraft that they fly on. There are a LOT of "Green Miles" contributing to CO2 production, including the hot air they spout from their mouths].
2GT per year is quite a lot to be taken out of the atmosphere. After Peak Oil kicks in, how do you propose we keep the supply up? I suppose we could go back to coal. Or heavy crudes from Venezuela, but that'll cost more than easy to distill sweet crude oil. But there would be increased CO2 produced per kilometre travelled, so I suppose CO2 production wouldn't reduce.
But with higher costs, people will be inclined to travel less and more efficiently and use more insulation etc.
