Scientists believe that volcanic explosions in Siberia are the main reason, since in the atmosphere they were released a huge amount of greenhouse gases, which led to a sharp warming, and the planet turned into a “glass house in hell”, which lasted millions of years.
The authors of the new study suggested that the Earth very quickly increased its temperature, which led to the extraction of vegetation from low to medium -widths, especially tropical tropical forests.
After the disaster, tropical tropical forests and peats, which were almost absorbed in carbon, disappeared and were replaced by primitive plants. This slowed down a carbon cycle, and greenhouse gases remained longer in the atmosphere, maintaining the maximum temperature. The climate gradually began to return to normal life after about five million years, when the plants began to recover.
Scientists agreed that this event led to serious emissions from greenhouse gases, which led to intensive and extensive warming of the Earth. However, the puzzle remains around the continuation of these hot conditions for millions of years. This comes from a new study published in Nature Communications.
A flash of huge amounts of magma from Siberian traps was a spark that lit a collective extinction in the piercing era. And this magma rose in the sedimentary pool rich in organic materials. It was hot enough to dissolve the surrounding rocks and launch a huge amount of carbon dioxide in the atmosphere of the atmosphere for some time, which is considered short in geological standards, which could vary from 50,000 to 500,000 years.
It is believed that the temperature on Earth rose very quickly, which prevented the ability of many forms of life to develop and adapt. The restoration of the climatic system requires such disasters that vary from 100,000 to a million years. However, these climatic conditions with the average temperature at the equator exceeding 34 ° C (that is, it is about 8 degrees Celsius than the current level) lasted almost five million years.
