In recent years, scientists have preferred to limit the existential threat of our planet to the impact of asteroids that approach us, but the rocks of space have been repositioned by carbon in the atmosphere .
Scientists in the 1990s thought that asteroid collisions were responsible for five massive extinctions, including dinosaurs, 65 million years ago.
Today, scientists have realized that the other four disasters were caused by massive carbon emissions into the atmosphere and oceans.
What he called the name is among the worst of these events. "The end of the barrel", A geological age that began with a volcanic eruption that ignited carbon-rich deposits and flooded the atmosphere with carbon dioxide in a few thousand years, resulting in the loss of 90% of living organisms .
Thus, the principle that the increase in carbon dioxide not only makes the universe warmer, but rapidly changes the chemistry of the oceans and the atmosphere, causes a rearrangement of the living world.
All in all, this also causes chemical changes affecting the biosphere: fish and plankton failures occurred at the end of the Permian, while the explosion of bacteria also contributed to the release of sulfated compounds and methane, " Bloomberg ".
Transfer "Bloomberg" About Seth Burgess, geologist at the US Geological Survey, specializing in the study of the late Permian, claiming it "A mystery", Although it is agreed that the Volcanic activity has led to the formation of blocks called "Siberian traps" But these revolutions have not released enough greenhouse gases to cause a rise in temperature from 10 to 15 degrees Celsius.
Bergis suggested that the molten material formed carbon – rich sediments, which were massively released into the atmosphere, while oxygen was considerably reduced in the oceans, causing the death of many organisms.
He described the world of fossils Peter Ward in his book "Under the Green Sky", which occurred after the end of the Permian era, where decaying organic elements have spread and where bacteria have proliferated under the hot sun.
Daniel Rothman, professor of geophysics, said At the Massachusetts Institute of Technology, That the universe is unable to adapt to the rapid increase of carbon, which may not cause the current emissions of human beings from carbon to the destruction of the universe, unless the volume of saying in the oceans reaches 310 Gt.
The United Nations Intergovernmental Panel on Climate Change (IPCC) estimates that human activity will add 300 to 500 gigatons of carbon dioxide to the oceans by the end of the 21st century.

"There is a mystery," he said. "Although it was agreed that volcanic activity was at the origin of the formation of so-called Siberian traps," said Seth Burgess, geologist at the US Geological Survey , specialist in the study of the end of the Permian. But these revolutions have failed to release enough greenhouse gases to cause a temperature rise of 10 to 15 degrees Celsius.

In his book Under the Green Sky, paleontologist Peter Ward described what happened after the end of the Permian, where decaying organic elements spread and where the bacteria proliferated under the hot sun.
Daniel Rothman, a professor of geophysics at the Massachusetts Institute of Technology, said the universe was unable to cope with the rapid rise in carbon, suggesting that current human emissions would only result in a "high" carbon footprint. carbon destruction of carbon only if the volume of the ocean increased to 310 Gt.
