Study predicts the oceans will start emitting ozone-depleting CFCs

MIT News  March 15, 2021 The levels of CFC-11 in the atmosphere have been steadily declining since 2010 under the Montreal Protocol, ocean absorbing about 5 to 10 percent of all manufactured CFC-11 emissions. A team of researchers in the US (MIT, Colorado State University, UC Santa Barbara, NASA Goddard Space Flight Center) looked to pinpoint when the ocean would become a source of the chemical, and to what extent the ocean would contribute to CFC-11 concentrations in the atmosphere. Through a hierarchy of models to simulate the mixing within and between the ocean and atmosphere, and adding anthropogenic emissions […]
