Over millions of years in the UAE stony desert almost nothing has changed, which creates unique conditions for scientists and paleontologists. At this time, as reported by the newspaper "National", United Arab Emirates (UAE) discovered the secret of a mass extinction of sea creatures in permo- the Triassic period 252 million years ago.

The study of the Emirates rocks, the newspaper writes, revealed that the cause of the ecological catastrophe became carbon dioxide emissions into the atmosphere by volcanic eruptions. Then hot lava had an impact on sedimentary carbonate rocks, which led to an increase in acidity in the oceans.

According to the newspaper, it was possible to learn in the course of analysis of the various layers of rocky deposits in the UAE, which at the end of the Permian period is the seabed. It turned out that the "Permo-Triassic" extinction took place in two stages. First, the saturation of the atmosphere with carbon dioxide is fairly slow, which caused the disappearance of a significant number of sensitive organisms to the environment. Gradually, the level of emissions reached dangerous levels, which had a direct impact on the marine environment. As a result, about 90 percent of sea creatures became extinct.

The study of this process as the scientist said in an interview with reporters "National" to better understand the phenomena that take place in our time. "More than 250 million years ago, the volcanic activity of the released energy is much greater than all the power of modern humanity - seen at the University of Edinburgh. - However, the key point in this regard is precisely the rate of saturation of the atmosphere with carbon dioxide. In this respect, the situation today repeats the model permo- Triassic extinction. "

The disaster at the turn of the Permian and Triassic period is considered the largest in the history of our planet. Total science knows of five such events, including small-Paleogene extinction 66 million years ago, when the dinosaurs disappeared all land.
