New projections highlight potential climate risks to exploitable fish biomass for nearly all regions of the world’s ocean, including top producer countries and those with high reliance on aquatic foods, according to a report released by the Food and Agriculture Organization of the United Nations (FAO).
Global projections of exploitable fish biomass show declines of more than 10 percent, particularly under the high-emissions scenario, by mid-century for many regions of the world, said the report Climate change risks to marine ecosystems and fisheries: Projections to 2100 from the Fisheries and Marine Ecosystem Model Inter-comparison Project.
By the end of the century, under the high-emissions scenario, which projects global warming of 3–4.0 °C, declines worsen to 30% or greater in 48 countries and territories.
In contrast, under the low-emissions scenario, which projects global warming of 1.5–2 °C, changes stabilize between no change and a decrease of 10% or less across 178 countries and territories by the end of the century.
