End permian extinction cause
The end-Permian mass extinction is widely regarded as the largest mass extinction in the past 542 million years with loss of about 95% of marine species and 75% of terrestrial species. There has been much focus and speculation on what could have caused such a catastrophe. Despite decades of study, the cause or causes remain mysterious.The scientific consensus is that the main cause of the End-Permian extinction event was the large amount of carbon dioxide emitted by the volcanic eruptions that created the Siberian Traps, which elevated global temperatures. The formation of large igneous provinces by flood basalt events could have:
