New research from the University of North Carolina at Chapel Hill and collaborators found that most marine life in Marine Protected Areas will not be able to tolerate warming ocean temperatures caused by greenhouse gas emissions. Marine Protected Areas have been established as a haven to protect threatened marine life, like polar bears, penguins and coral reefs, from the effects of fishing and other activities like mineral and oil extraction. The study found that with continued “business-as-usual” emissions, the protections currently in place won’t matter, because by 2100, warming and reduced oxygen concentration will make Marine Protected Areas uninhabitable by most species currently residing in those areas.
