Diets reliant on marine fisheries and fish also face complex climate- driven challenges . Rapidly warming oceans  limit the size of many fish and hamper their ability to relocate or adapt; many commonly consumed fish, like sardines, pilchards and herring, could face extinction due to these pressures . Other fisheries models project end- of-century pollock and Pacific cod fisheries decreasing by > 70% and > 35% under RCP8.5 . Climate-driven increases
