IM Sea grass beds, like these off the coast of British Columbia, Canada, might buffer the impacts of ocean acidification (Christopher Harley, University of British Columbia).

Acidification of the world’s oceans could drive a cascading loss of biodiversity in some marine habitats, according to research published today in Nature Climate Change.

The work by biodiversity researchers from the University of British Columbia (UBC) and colleagues in Europe, Australia, the U.S., Japan and China, combines dozens of existing studies to paint a more nuanced picture of the impact of ocean acidification.
