Global Warming And The End-Permian Extinction Event: Proxy And Modeling Perspectives, Ying Cui, Lee R. Kump
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
The mass extinction event that occurred at the close of the Permian Period (~252million years ago) represents the most severe biodiversity loss in the ocean of the Phanerozoic. The links between the global carbon cycle, climate change and mass extinction are complex and involve a whole range of often inter-related geochemical, biological, ecologic and climatic factors. It has become widely accepted that the end-Permian mass extinction was associated with a global warming event, because the age of the Siberian Trap eruption, a potentially massive source of carbon dioxide, coincides within error with the extinction event. However, geologic data that are …
