Nearly all marine species face extinction if greenhouse emissions don’t drop: study

Maintaining the status quo for greenhouse gas emissions could risk the extinction of up to 90 percent of marine species, according to a study published Monday in the journal Nature Climate Change. 

Researchers, led by ecologist Daniel Boyce of the Bedford Institute of Oceanography in Nova Scotia, looked at some 25,000 species, including animals, plants, protozoans and bacteria. Under a high-emission scenario, they determined that nearly 90 percent of those species will be at high-to-critical risk across 85 percent of their distribution. This scenario involves an increase of 3 to 5 degrees Celsius in global ocean temperatures by the end of the century.
