Top fish predators could suffer wide loss of suitable habitat by 2100 due to climate change

A study of 12 species of highly migratory fish predators — including sharks, tuna, and billfish such as marlin and swordfish — finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in the Northwest Atlantic Ocean (NWA) and the Gulf of Mexico (GOM) by 2100. These areas are among the fastest warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems. …read more
