Climate change could kill 50-80% of Pacific fish species: study

From , 6:04 am on 22 November 2017

Pacific island nations could lose between 50 and 80 percent of their fish species by the end of the century if climate change continues unabated.

The figure is published in a new study, published in the journal Marine Policy, which examined more than a thousand species across the region to see how they are reacting to changes in the ocean.

Its lead researcher, associate professor Rebecca Asch from the University of East Carolina, says the Pacific's temperature has little variability, with the temperature being more or less the same all year.

She told Jamie Tahana this means species are unlikely to be able to adapt to dramatic changes in ocean temperatures, and could die out.
