Excerpt: Marine fish around the world are already feeling the effects of climate change—and some are reeling, according to the first large analysis of recent trends. Rising sea temperatures have reduced the productivity of some fisheries by 15% to 35% over 8 decades, although in other places fish are thriving because warming waters are becoming more suitable. The net effect is that the world’s oceans can’t yield as much sustainable seafood as before, a situation that is likely to worsen as global warming accelerates in the oceans. A silver lining is that the research suggests well-managed fisheries are more resilient in the face of rising temperature, says Rainer Froese, a marine ecologist with the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, who was not involved in the work. “We have to stop overfishing to let the gene pool survive, so that [the fish] can adapt to climate change,” he says. “We have to give them a break.”...
