Ocean temperature is now the primary climate-induced threat to North Atlantic calcifying plankton

Ocean temperature is now the primary climate-induced threat to North Atlantic calcifying plankton according to research published in the paper “Long-term responses of North Atlantic calcifying plankton to climate change” in the journal Nature Climate Change.

This study suggests that although ocean acidification may become a serious threat in the future, from 1960–2009 the primary driver of change was ocean temperature.

Gregory Beaugrand and co-workers investigated the effects of ocean acidification and temperature change on marine-calcifier diversity in the North Atlantic Ocean.

By analysing biological data and physical parameters, they show an abrupt shift in plankton communities around 1996, corresponding to a substantial temperature increase.

They also note that some species showed poleward movement, in agreement with expected biogeographical changes under ocean warming.
