Oxygen will disappear on Earth, making it impossible for life, including humans, to survive,Prediction that will happen

 

 

Tokyo: A supercomputer simulation conducted by researchers at Toho University in Japan using NASA's planetary modeling (a method of analyzing complex issues using supercomputers) predicts that oxygen will disappear on Earth within 1 billion years. It is predicted that oxygen on Earth will disappear in about a billion years, making it impossible for life, including humans, to survive. The evolution of the Earth's atmosphere was studied using 400,000 simulations. It is said that the Earth's biological atmosphere will disappear in exactly 1,000,002,021 years.

As the Sun ages, it will become hotter and brighter. This will affect the Earth's climate. Water will evaporate, surface temperatures will rise, the carbon cycle will weaken, and plants will disappear. The oxygen will gradually disappear. The researchers say this change will lead to a high methane state reminiscent of Earth before the Great Oxidation Event. The study, titled 'The lifespan of Earth's oxygenated atmosphere,' is published in Nature Geoscience. The lifespan of Earth's biosphere has been debated for years, based on scientific knowledge of the sun's constant luminosity and the global carbonate-silicate geochemical cycle, said Kasumi Ozaki, an assistant professor at Toho University in Tokyo, Japan, in a news release.
It is generally believed that Earth's biosphere will end within 2 billion years due to a combination of extreme warming and a shortage of carbon dioxide, which is needed for photosynthesis. We can expect the amount of oxygen in the atmosphere to gradually decrease in the distant future. However, it is not clear exactly when and how this will happen. The researchers say that if oxygen disappears, Earth's biosphere will disappear within 1 billion years.
