Scientists have long suspected that the cause of the cooling was the fall of atmospheric carbon dioxide concentration, which supported the warm climate of the planet through the greenhouse effect, but direct evidence of this until recently it was not. The researchers were able to prove that during the climatic transition content of carbon dioxide in the atmosphere has decreased from fifteen hundred to seven hundred ppm, then it concentration rose again to its former level and then began to fall steadily. When the concentration of carbon dioxide in the atmosphere has reached approximately 760 millionth shares began the birth of Antarctica.
