End-Permian Marine Mass Extinction Caused by Increased Temperatures, Oxygen Loss: Study

Schematic illustration of temperature-dependent hypoxia as a driver of the end-Permian marine mass extinction. Greenhouse gas forcing in a model of Earth’s climate at the end of the Permian drives ocean warming (contours) and oxygen loss that match geochemical proxy data. Ocean warming raises the organismal oxygen demand amid declining supply. The resulting loss of aerobic habitat for diverse physiologies induces a mass extinction in model animal types (line) whose geographic signature -- increased severity outside of the tropics -- is consistent with reconstructions from the marine fossil record (circles).

Some 252 million years ago, intense volcanic activity belched massive volumes of greenhouse gasses into the atmosphere and triggered rapid changes to the climate, which resulted in the end-Permian mass extinction, the largest mass extinction event in Earth’s history. Nearly 96% of all marine species were wiped out during the extinction even, followed by millions of years when life had to multiply and diversify once more. According to a new study...
