How a heat wave in 2003 has changed the North Atlantic until today

A major North Atlantic #MarineHeatwave in 2003 reshaped marine life from plankton to whales, driving long-term shifts towards warmer-water species.

The study shows these shifts had lasting ecological and social consequences, from altering food webs to fisheries productivity.
