The oceans could look much emptier by 2100, according to a new study that found that most fish species would not be able to survive in their current habitat if average global temperatures rise 4.5 degrees Celsius by the end of the century, as The Guardian reported.

The researchers of the new paper said that 60 percent of fish species face a grave threat from global heating if temperatures approach that worst-case scenario level. The species under threat include many common fish found in grocery stores, including staples like Atlantic cod, Alaska pollock and sockeye salmon, and sport fishing favorites like swordfish, barracuda and brown trout, as CNN reported.

The new study, published in the journal Science, looked at how nearly 700 fresh and saltwater fish species respond to warming ocean temperatures. The problem for most fish is that as ocean temperatures rise, the oxygen […]
