Volcanism drove rapid ocean deoxygenation during the time of the dinosaurs

Continental volcanic arcs such as this one in Kamchatka, Russia, are rapidly weathered, driving CO2 removal from the atmosphere over geological time. Credit: Tom Gernon, University of Southampton

Volcanoes acted as a safety valve for Earth’s long-term climate

A view of Kīlauea’s summit lava lake. The lava lake is contained within a crater, which is set within the larger Halema‘uma‘u Crater. New research aims to understand the activity that led to the eruption in 2018 in Kīlauea’s lower East Rift Zone. Credit: USGS
