Date of New Global Mass Extinction on Earth

The scientists are convinced that Earth will face the new wave of the extinction event. Already now, many species populations are declining.

The experts analyzed and compared how this situation changed during last century. Thus, in 1950 there were circa 400 thousand lions, nowadays there are no more than 25 thousand these predators. The lions live on the territory of Central Africa and India. On other areas, these animals died or were killed by people.

During the period of 1950-2015, circa 80 % of the mammals died including billions of birds, reptiles and amphibians. Based on this information, two years ago the scientists stated about the sixth global mass extinction event. According to their calculations, until the Anthropocene, at least two species of mammals died each century. In XX and XXI centuries this number increased by 114 times.

In the history of Earth, five periods of extinction event was recorded. The last extinction took place between the Permian and Triassic geologic periods. The scientists believe that up to 75% of species died because of the volcanic activity and impingement of Earth with asteroids circa 65 million years ago.

The next global mass extinction event will start in 2100 on Earth. During that time, the concentration of the carbon dioxide in the oceans will exceed the critical level and the temperature will start to increase on the planet.

Daniel H. Rothman, a Professor of Geophysics in the Department of Earth, Atmospheric, and Planetary Sciences at MIT says: “This is not saying that disaster occurs the next day. It’s saying that, if left unchecked, the carbon cycle would move into a realm which would be no longer stable, and would behave in a way that would be difficult to predict. In the geologic past, this type of behaviour is associated with mass extinction.”

In XXI century, the experts recorded new global climate change. As a result, most of the biological species will disappear. The mass extinction event takes place on the African continent, Asia and the British Isles.
