Ocean acidification will likely almost triple by the end of the century—a drastic environmental change that could impact important marine species like fleshy seaweeds, algae that grow vertically and promote biodiversity in more than a third of the world's coastline. To get a better idea of how seaweeds might fare in a rapidly acidifying ocean, a team of Swedish marine scientists subjected a common fleshy seaweed species to the acidification levels expected by the end of the century.
