The oceans are already absorbed enormous amounts of atmospheric CO2, and it's messing up marine ecosystems by changing pH levels, among other things. It's a major cause of coral loss and possibly of jellyfish population growth. The reason IMO, for fighting things tooth and nail is that the systems we are dealing with are complex and interconnected, sort of like the world economy - which has billions of dollars of modeling yet still can't predict effects of simple changes. Major changes in any ocean system will have unpredictable effects in others.

And coral is a great CO2 absorber...

Coral is a great CO3 absorber. CO2 can acidify the ocean water, which lowers calcification rates affecting the ability to grow carbonate skeletons. Combined with an increase of CO2 in the atmosphere contributing to a global increase in temperature, which coral is extremely sensitive to, and an increase of CO2 anywhere is bad news.
