Warming, low oxygen oceans caused Earth's biggest mass extinction 252 million years ago
Around 252 million years ago, approximately 96% of marine species were eradicated in the "Great Dying", a mass extinction event caused by warming waters and oxygen depletion. A new Stanford-led study, published on 6 July, found that animals less able to cope with these conditions suffered the highest extinction rates. Scientists state that these findings provide a cautionary tale regarding the potential reactions of contemporary marine life to ongoing climate change.
