Coccolithophores ...our very small, beneficial friends

I have made a few previous posts about Coccolithophores and why they gave me hope for their potential Earth saving contributions. In Carbon Eaters of the Black Sea they re-emerge as a source of hope for our planet, but also a question is raised as to whether ocean acidification will significantly interfere with their beneficial role.
