— another potential catastrophe has come into view: depleted oxygen levels in the world's oceans and lakes that threaten marine life. As ocean and atmospheric scientists focus on climate, we believe that oceanic oxygen levels are the next big casualty of global warming
In part due to the effects of rising global temperatures, growing portions of the oceans have lost "10-40 percent of their oxygen," and that figure is forecast to continue growing due to climate change. this year in states like Florida, California, Oregon, Montana, Louisiana, Virginia, Pennsylvania, Missouri, Washington, Idaho, Delaware and Minnesota.
