The Earth’s atmosphere will lose all free oxygen in the future. This is the conclusion reached by Kazumi Ozaki, a Japanese scientist at Toho University, and his American colleague Christopher Reinhard from the Georgia Institute of Technology. The study is published in the journal Nature Geoscience.
Experts have modeled the evolution of the atmosphere of our planet, taking into account geological, biological, and climatic factors. As a result, they found that the Earth’s atmosphere will remain relatively stable for about a billion years, and after that, it will turn almost oxygen-free in a few thousand years.
According to scientists, the cause of the disaster will be the increased activity of the Sun, due to which the content of carbon dioxide in the atmosphere will decrease. When this indicator reaches a critical point, the process of photosynthesis will be disrupted on the planet, and oxygen will no longer enter the atmosphere.
“The biosphere will not have time to adapt to such significant changes in the environment. The world of primitive anaerobic microbes, which is now hiding in the shadows, will take up again,” the scientists concluded.
