What is Pnas 202420505 about?
This research article investigates the occurrences of marine anoxia during the Late Paleozoic Ice Age, a period characterized by high atmospheric oxygen levels and low CO2 concentrations. The study utilizes high-resolution carbonate uranium isotopes to reconstruct marine redox evolution and finds that despite elevated oxygen, short-term marine anoxia events were prevalent, likely driven by CO2 emissions. The findings highlight the potential for ocean deoxygenation under similar future climate conditions, em
