Volcanic activity, declining ocean oxygen triggered mass extinction of ancient organisms

Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today’s oceans at an alarming pace—so fast that scientists aren’t entirely sure how the planet will respond. Their only hint? Look to the past. In a study to be published this week in the journal Proceedings of the National Academy of Sciences, researchers from Florida State University did just that—and what they found brings into stark relief the disastrous effects a deoxygenated ocean could have on marine life. While researchers have long surmised a link between volcanism, loss of oxygen and mass extinction, this study provides the first conclusive data.
