Fisheries output to plunge unless global warming reeled in

This article points out the dire impact that global warming will have on the world’s fisheries, if we don’t change direction. Global fisheries output will slump by 20 percent by 2300 and by 60 percent in the worst-hit North Atlantic region if governments fail to slow long-term global warming, a U.S. team of scientists said.

Most studies of climate risks extend to 2100 and overlook extra “catastrophic effects” such as the projected slump in ocean life that would only emerge in coming centuries, they said.

Unchecked long-term warming would thaw sea ice around Antarctica and disrupt ocean currents, winds and the growth of tiny plankton, the report found. Worldwide, ever more nutrients would sink to the ocean depths, away from fish near the surface.

“Marine ecosystems worldwide will be increasingly starved for nutrients,” lead author J. Keith Moore of the University of California, Irvine, told Reuters of the findings published in the journal Science.
