Professor Masayuki Ikeda of the Department of Planetary and Earth Studies at the University of Tokyo predicts the beginning of a new ice age on the planet after 100,000 years.
Professor Ikeda and his colleagues conducted a scientific study on the influence of monsoons and the development of dinosaurs ten million years ago, using the theory of Serbian engineer Milutin Milankovic in which he linked the fluctuations in the amount of sunlight and radiation to the change of the angle of inclination of the Earth’s axis to the level of Earth’s orbit.
“According to Milankovitch’s theory, after 100,000 years a new ice age will begin, but this depends on the human factor and the emissions of carbon dioxide,” the professor said in an interview with the Russian news agency RIA Novosti.
The new study indicates that the decrease in the concentration of carbon dioxide and the climate on the earth, along with the monsoons, led to an increase in the size of the dinosaurs. The area of their settlement on the planet also expanded, as a result of the expansion of food and water sources in the Triassic period from the middle life era, about 212 million years ago.
According to the professor, the Earth is now at the height of a ten-million-year cycle with a very cold seasonal climate and a low concentration of carbon dioxide in the atmosphere. And this time may be appropriate for living creatures, who are used to cold and high humidity.
The next study will focus on the issue of the impact of a ten-million-year cycle on the evolution of not only dinosaurs, but also mammals and plants.
