This article discusses 2 studies that show how climate change is impacting fish production across the oceans.
The study of past changes to ocean fisheries, published Thursday in the journal Science, looked at the impact of rising ocean temperatures on 124 marine species representing about one-third of the global catch from 1930 to 2010. It found that the “maximum sustainable yield,” or the amount of fish that could be caught each year without jeopardizing future harvests, dropped by 4.1 percent over this period as a result of climate change.
A second study, published in the journal Science Advances, considered the extent to which global fisheries would benefit if global warming is limited to the Paris Agreement goal of 1.5 degrees Celsius above pre-industrial levels, as compared to a “business-as-usual” pathway based on current greenhouse gas mitigation policies that would bring 3.5 degrees of warming.
