German scientists have predicted that in the future our planet will face a catastrophe of hypoxia comparable to what happened on Earth 2.4 billion years ago.
The German newspaper Frankfurter Rundschau reported that oxygen is depleted on Earth, and if it is not depleted due to climate changes, the sun will inevitably burn its reserves.
In order to calculate when Earth will run out of air, scientists have modeled the climate, biological and geological systems of our planet. In the course of that study, they explained that Earth’s oxygen-rich atmosphere would not last long.
According to scientists’ calculations, after a billion years, our planet will not be suitable for complex aerobic life, because the proportion of oxygen in the atmosphere will be very low, less than 1%. Today, this indicator is more than 21%.
The reason for this, according to the study, lies in the sun, which will become hotter and therefore more active. As a result, the carbon dioxide content in the atmosphere will begin to drop sharply, because this gas absorbs heat and then decomposes.
In the future, the level of carbon dioxide in the atmosphere will become 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 enhance the greenhouse effect.
Scientists assume that at first the oxygen content on Earth will remain high, then it will decrease sharply, after which the “oxygen catastrophe” will occur, as it happened about 2.4 billion years ago. Planet Earth Will Suffocate.
One of the researchers said: “The decrease in oxygen will be very critical. Its quantity will be about a million times less than it is today. At the same time, changes will occur rapidly in the atmosphere of our planet. In only 10,000 years, the oxygen will disappear.”
Scientists had earlier warned humanity of a possible lack of oxygen. And they said, “If that happened, all living things on the planet would perish because they depend on oxygen.” Planet Earth Will Suffocate.
