German scientists predict that in the future our planet will face a catastrophic event of hypoxia comparable to what happened on Earth 2.4 billion years ago.
The German newspaper Frankfurter Rundschau reports that the Earth is depleted of oxygen and that if it does not deplete due to climate change, the sun will inevitably burn up its reserves.
To calculate when the Earth’s air will run out, scientists are modeling our planet’s climate, biology, and geography. During that study, they explained that the Earth’s oxygen-rich atmosphere would not last long. Scientists estimate that after a billion years, our planet will not be suitable for complex aerobic life because the ratio of oxygen in the atmosphere will be very low, less than 1%. Today, this indicator is over 21%.
The reason for this, according to the study, is in the sun, which becomes hotter and therefore more active. As a result, the carbon dioxide content in the atmosphere begins to decrease drastically, as this gas absorbs heat and then decomposes.
In the future, the amount of carbon dioxide in the atmosphere will be so low that photosynthetic organisms, including plants, will not be able to produce oxygen and survive. According to scientists, this percentage will increase 10 thousand times, which will further increase the greenhouse effect.
Scientists first assume that the oxygen content of the Earth will be high, then it will decrease sharply, followed by the “oxygen catastrophe” that occurred about 2.4 billion years ago.
One of the researchers said: Lack of oxygen is very important. Its size is a million times smaller than it is today. At the same time there will be rapid changes in the atmosphere of our planet. In another 10,000 years, oxygen will be gone. “
Scientists had earlier warned humanity that a lack of oxygen could occur. They said, “If that happened then all the living things on the planet would be extinct because they depended on oxygen.”
