A study published in the magazine Nature Geoscience It reveals that the day will come when oxygen ends on earth. The researchers, headed by the environmental scientist Kazumi Ozaki, projected the evolution of the gases of our atmosphere by modeling the climatic, biological and geological systems, with almost 400,000 simulations.
This reflects la web Meteoredwhere they point out that the study considers the changes in the sun’s brightness, variations in carbon dioxide and changes in the earth’s biosphere, to conclude that methane will abound on our planet and, finally, oxygen will be exhausted.
“We use a combined model of biogeochemistry and climate to examine the probable time scale of oxygen -rich atmospheric conditions on Earth,” explains the study.
The portal himself has responded to the moment this will happen and, luckily, “it will be in a few million years.” The main reason for the end of oxygen, according to the study, is in the process of aging of the sun, which over the years will heat more and release more energy.
This will lead to a reduction in carbon dioxide in the atmosphere, since CO2, by absorbing heat, decomposes. “We are talking about about a million times less oxygen than there is today,” he says.
Currently, oxygen constitutes about 21% of the Earth’s atmosphere, which enables life for large and complex organisms, such as humans. But it will not be eternal. “We discover that the oxygenated atmosphere of the Earth will not be a permanent characteristic,” says Ozaki.
