CO2 reduction not enough to reverse ocean damage

News in Science CO2 reduction not enough to reverse ocean damage No plan B Technology to drain heat-trapping CO2 from the atmosphere may slow global warming, but will not reverse climate damage to the ocean on any meaningful timescale, according to new research. "We show that in a business-as-usual scenario, even massive deployment of CO2 removal schemes cannot reverse the substantial impacts on the marine environment -- at least not within many centuries," says Mathesius. "Immediate and ambitious action to reduce CO2 emissions is the most reliable strategy for avoiding dangerous climate change, ocean acidification, and large-scale threats to marine ecosystems," the researchers conclude. "The threat of ocean acidification alone justifies dramatic and rapid reduction of CO2 emissions," says Nick Riley, a research associate at the British Geological Survey.
