This is a solicited blogpost written by Lawrence Percival, who will also present his work on the Oceanic Anoxic Event 2 as part of session SSP2.1 of the upcoming EGU GA. The increasing concern regarding 21st climate change and environmental disturbance has led to a renewed focus on similar episodes of global crisis through Earth’s history. During the Late Devonian Period, 380–360 million ye ...[Read More]
