Researchers rethink fate of celebrity plankton

A widespread plankton has startled marine biologists by thriving in seawater doctored in the lab to simulate conditions predicted for the year 2100. The plankton, a coccolithophore called Emiliania huxleyi, had become an iconic species for the perils of greenhouse gas buildup. Since the beginning of the industrial era, humans have added enough carbon dioxide to the atmosphere to nudge seawater closer to acidity.
