Scientists from China, the Netherlands and Norway discovered that the cause of the mass extinction in the Permian period was the result of a sharp rise in temperatures caused by the volcanoes of Siberia.
The Proceedings of the National Academy of Sciences notes that the Burmese mass extinction, considered the largest catastrophe in Earth's history, was caused by volcanoes in Siberia that released huge amounts of carbon dioxide.
It became clear to the researchers, after they added the ratios of carbon isotopes, which they took from the fat of fossils of algae and plants, to a model to describe the Earth, that the results of the calculations carried out with the help of astronomy, that the carbon emission is large-scale (more than 36 thousand gigatons) and rapid (at a rate of 5 gigatonnes per year over 109,000 years), can be explained by volcanic terraced rocks in the Siberian region.
Professor Wolfram Korschner from the University of Oslo says, "Our calculations showed that two volcanoes were the main source of carbon dioxide emissions and an increase in its proportion in the Earth's atmosphere. This raised the gas concentration from 400 parts per million by volume, to ten thousand, which led led to a sharp rise in temperatures at the end of the Permian mass extinction."
