August 13, 2019 — Climate change will cause fish biomass to decline 5 percent for every one degree Celsius of warming, according to the most comprehensive analysis of marine ecosystem models to date.
The study, which was authored by 35 researchers from 12 countries, combines multiple climate and ecosystem models to create an ensemble model that estimates future global marine biomass — the total weight of all the fish, invertebrates, and marine mammals in the ocean.
