Global Warming

With record summer heat and drought threatening wild salmon in California, the Pacific Northwest, British Columbia and Atlantic Canada this summer, experts say many commonly eaten fish could face extinction as global heating makes waters too hot for them to survive.

A report in the journal Nature Climate Change warns many species will struggle to keep pace with the deepening climate emergency. “Warming waters are a double whammy for fish, as they not only cause them to evolve to a smaller size, but also reduce their ability to move to more suitable environments, said co-author Chris Venditti of Britain’s University of Reading. He warns this could threaten global food security.
