New insights into the mass extinction of the end of the Permian period 252 million years ago. The mass extinction of the end of the Permian period was a major problem. It was the largest mass extinction event, which occurred 252 million years ago. Nearly 90% of all marine species and about 70% of their land relatives are extinct.

Over the years, many efforts have been made to investigate this great and developing global event. The end-Permian mass extinction coincided with massive eruptions in Siberian fisheries, some potential scenarios including volcanoes producing acid rain, volcanoes burning coal (which transports greenhouse gases to the atmosphere), and reduced availability. The presence of oxygen in the ocean, among other things, a new paper looks at previously unused data and models. Overall, the study found that 36,000 gigatons of carbon -- more than volcanic sources -- were partly released into the atmosphere. The shortening of the 15,000-year period of this period also led to a significant increase in the average global temperature, from 25°C to 40°C. While researchers have previously looked at volcanoes and carbon as potential causes of large-scale extinctions, this provides further insight into the event, said Wolfram Korschner, a geologist at the University of Oslo and co-author of the research paper. Korschner told Ars. "Until now, it has been very difficult to quantify the amount of carbon dioxide released into the atmosphere." These samples are taken from sediments extracted from the Norwegian Finmark platform, located in the eastern part of the Barents Sea, which, according to Tsoi, was completely protected and allowed to flow during this period. Carefully note the combinations of vital signs in the ocean and on land.

After observing the data, the team published a series of models that allowed them to generate and emit carbon. Pier says to Ars, “When you combine [data and modeling], it becomes very powerful and can reveal new insights that we can look at. We can't identify them separately. Along with global warming, rising carbon dioxide and changes in the carbon cycle can lead to Lowering the pH of the world's oceans. This acidification may be partly responsible for the extinction of marine life. In fact, even current levels of ocean acidification with human carbon release (which is relatively mild compared to volcanic eruptions) is melting the crust of some marine organisms.
