  1. The Permian Triassic Extinction Event The role of Global Warming in the PTEE EvelinCollado and Matthew Moline

  2. Introduction • 251 million years ago • Up to 92% of species became extinct. • What role did Global Warming play in this crisis?

  3. PTEE Mechanisms • CO2 Increase • Ocean Circulation • Storm Activity • Anoxia • Volcanism • Hypercapnia • Methane Release • Bolide Impact

  4. Comparison • Early Permian and Modern Era are similar • Late Permian: Siberian Traps erupt • Early Triassic: Additional Kill Mechanisms

  5. Conclusion • Global Warming was a critical component of the most profound extinction event of the last 600 million years. HOWEVER • Atmospheric CO2 is currently increasing 100x faster than during the PTEE • Temperature is currently increasing 660x fasterthan during the PTEE
