December 11, 2019 — 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.
“The changes going on have the potential to influence the kinds of fish products you have available to you, whether that’s fish sticks in the grocery store or shellfish at a restaurant,” said Rick Thoman, a meteorologist in Alaska and one of the report’s authors.
