Cause of History’s Largest Mass Extinction Revealed

A new study published in the scientific journal Science Advances has revealed a new cause of the biggest extinction ever experienced on Earth. ‘The Great Extinction’ so-called Permian-Triassic mass extinction event, approx. 250 million years ago took place. 80-90% of land and sea creatures There was another reason for this event, in which part of it disappeared.

By examining the geological remains, scientists discovered that a large part of the ozone layer was destroyed by the sudden decrease and rise in the oxygen level during this period, and the ocean chemistry was also changed. For this reason, in Siberia volcanic eruptions lasting up to a million years was displayed. Researchers have now found a different reason for this mysterious extinction event.

The world experienced a harsh winter just before it scorched:

The information obtained so far indicates that the carbon dioxide released into the atmosphere by the erupting volcanoes in Siberia has turned the planet into an oven and acidifying the oceans It signified that he had put an end to his life. However, new findings suggest that before this event happened, south of china It shows that the volcanoes in the region erupted and the volcanoes in Siberia had the opposite effect. Michael Rampino, a geologist at New York University, who stated that when they examined this period, they saw that there was more than one reason for the ‘extinction’ event, said that the copper, mercury and other mineral fragments they found in the south of China belonged to the Permian-Triassic mass extinction period. exposed to large amounts of sulfur It says they found it.

If volcanic eruptions release such concentrated sulfur into the atmosphere, will block the sunlight and will lower the temperature Researchers suggest that the Earth’s surface may have cooled considerably. Stating that the order of the atmosphere and ocean chemistry was destroyed by the temperatures experienced with the Siberian volcanic eruptions that followed, the researchers said that the Permian-Triassic mass extinction, which ended almost all of its life, occurred in two different places. states that volcanic eruptions may occur.
