May 8, 2018 (Source: UNC/ScienceDaily) - New research found that most marine life in Marine Protected Areas will not be able to tolerate warming ocean temperatures caused by greenhouse gas emissions. 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. "There has been a lot of talk about establishing marine reserves to buy time while we figure out how to confront climate change," said Rich Aronson, ocean scientist at Florida Institute of Technology and a researcher on the study. "We're out of time, and the fact is we already know what to do: We have to control greenhouse gas emissions."
