The Ordovician extinction occurred in two phases, destroying 60 to 70 percent of all species.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.

The Permian-Triassic mass extinction was therefore a cascading collapse of vital global cycles sustaining the environment driven by an immense multi-millennial carbon injection to the atmosphere.
