WASHINGTON/ANCHORAGE - 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.
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 report identified a decrease in recent years in the Bering Sea “cold pool,” which used to be a dependable mass of very salty frigid water down to the sea floor that functioned as a natural fence separating fish species. That has likely caused a shift in distribution of walleye pollock and Pacific cod, the report said.Fish stocks are scrambled, with some species moving north.
It also detailed a shift of Arctic permafrost regions from being a sink for carbon dioxide emissions to a source of them, as warming uncovers soil, triggering microbes to emit the main gas linked to global warming.
but for Trump this not is important.
