New research uncovers troubling ‘triple threat’ facing the world’s oceans: ‘The impacts of this have already been seen and felt’

Andrea Dutton, a climate scientist at the University of Wisconsin–Madison, compares the situation to the end of the Permian period 252 million years ago, when similar environmental changes led to Earth’s largest known extinction event. “Oceans aren’t just a nice backdrop for your selfies in summer; we rely upon them for our lives. It’s very important to recognize this,” Dutton said.
