Study says warming may reduce sea life by 17%
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 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 computerbased 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 Tuesday's 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 percnet, the study said.
