The world's oceans will likely lose about one-sixth of their fish and other marine life by the end of the century if climate change continues on its current path, a new study says. Every degree Celsius (1.8 degrees Fahrenheit) that the world’s oceans warm, the total mass of sea animals is projected to drop by 5 percent, according to a comprehensive computer-based study by an international team of marine biologists. And that does not include effects of fishing. If the world’s greenhouse gas emissions stay at the present rate, that means a 17-percent loss of biomass – the total weight of all the marine animal life – by the year 2100, according to a study in the Proceedings of the National Academy of Sciences. But if the world reduces carbon pollution, losses can be limited to only about 5 percent, the study said.
