This will happen in the coming years.
At the University of Southampton scientists found that mankind “will return” the earth in the distant past.
During the study experts found that the climate of our planet will return to the ancient figures. By 2025 the Earth will “return” to 3.3 million years ago.
In this period the amount of carbon dioxide in the atmosphere will exceed his record during the Pliocene epoch from 5.3 to 2.8 million years ago. Then the concentration of CO2 in the atmosphere reached 380-420 ppm. Now the figure is 415 particles.
These data experts have analyzed the chemical composition of fossils from the depths of the Caribbean sea. They showed that in the Pliocene the Earth was three degrees warmer and sea levels were higher.
