It is not enough still. But processing such huge volumes with current technology is out of reach. Might be easier to devise a biotech solution, but messing with ecosystems is quite risky nonetheless. An example would be putting carbon fixing bacteria or algae in the water, additionally replacing the plankton that died due to change in pH. We have similar technology for cleaning up oil spills and some chemicals, so why not dilute carbonic acid as well.
