WASHINGTON/ANCHORAGE (Reuters) - Climate change is causing chaos in the Bering Sea, home to one of America's largest fisheries, an example of how rising temperatures can rapidly change ecosystems important to the
economy, U.S. federal government scientists said in a report on Tuesday.
Rising temperatures in the Arctic have led to decreases in sea ice, record warm temperatures at the bottom of the Bering Sea and the northward migration of fish species such as Pacific cod, the U.S. National Oceanic and Atmospheric Administration, or NOAA, said in its 2019 Arctic Report Card.
While the changes are widespread in the Arctic, the effect on wildlife is acute in the eastern shelf of the Bering Sea, which yields more than 40% of the annual U.S. fish and shellfish catch.
