This mass extinction event is known as the Permian-Triassic ... However, if during the late Permian period the lack of dissolved oxygen is believed to be a consequence of a global warming (Zhang et al., 2018a), and during the late Ordovician period – a consequence of a climate cooling (Bartlett et al., 2018), what could cause it during other periods of mass extinctions is not yet clear.

Scientists call it the Permian-Triassic extinction or "the Great Dying" -- not to be confused with the better-known Cretaceous-Tertiary extinction that signaled the end of the dinosaurs 65 million years ago. Whatever happened during the Permian-Triassic period was much worse: No class of life was spared from the devastation.Warming of the Earth’s climate and associated changes to oceans were the most likely causes of the extinctions. At the end of the Permian Period volcanic activity on a massive scale in what is now Siberia led to a huge outpouring of lava. The eruptions also produced carbon dioxide, a greenhouse gas that helps warm the planet. ….
