Ocean Acidification
Brittlestars can survive acid oceans.
As carbon dioxide levels rise, increasingly acidic oceans compromise the calcification processes of ocean organisms. New results show that one species bumps up shell production - but at a steep cost.

As oceans grow more acidic, a tiny plant thrives.
As more carbon dioxide gets pumped into the air, oceans are becoming more acidic. Scientists say that is damaging coral and other marine life that make shell or other skeletal material. But researchers have discovered a hugely abundant plankton that actually likes the ocean more acidic.
