Doomsday Is Approaching! Life On Earth Will be Gone As Scientists Fear Atmospheric Oxygen Will Only Last For Another Billion Years

Representational Image (Photo Credits: Wikimedia Commons) The world is closing to annihilation as Earth will not be able to support and sustain life forever. Not a mere doomsday prediction, but real concern has been shown by researchers in their recent findings. As the ageing sun grows hotter, oceans on Earth will evaporate, and the atmosphere will escape into space. Scientists have found evidence that Earth will lose its oxygen-rich atmosphere in approximately one billion years. Yes, you read that, right! The Earth, formed approximately about 4.6 billion years ago, will lose its plant life, and without plant life, oxygen levels will also drop, causing a mass extinction event among animals.

Enjoy It While It Lasts: Dropping Oxygen Will Eventually Suffocate Most Life on Earth

3 MARCH 2021 For now life is flourishing on our oxygen-rich planet, but Earth wasn t always that way – and scientists have predicted that, in the future, the atmosphere will revert back to one that s rich in methane and low in oxygen. This probably won t happen for another billion years or so. But when the change comes, it s going to happen fairly rapidly, the study suggests. This shift will take the planet back to something like the state it was in before what s known as the Great Oxidation Event (GOE) around 2.4 billion years ago. What s more, the researchers behind the new study say that atmospheric oxygen is unlikely to be a permanent feature of habitable worlds in general, which has implications for our efforts to detect signs of life further out in the Universe.

How much longer will the oxygen-rich atmosphere be sustained on Earth?

However, the fundamental timescale of the oxygen-rich atmosphere on Earth remains uncertain, particularly for the distant future. Solving this question has great ramifications not only for the future of Earth s biosphere but for the search for life on Earth-like planets beyond the solar system. A new study published in Nature Geoscience this week tackles this problem using a numerical model of biogeochemistry and climate and reveals that the future lifespan of Earth s oxygen-rich atmosphere is approximately one billion years.
