Earth's Oxygen Depletion: A Sooner-Than-Expected Reality
Scientists Kazumi Ozaki and Christopher T. Reinhard have published a study in Nature Geoscience, warning that Earth's oxygen could disappear sooner than anticipated.
The study suggests that oxygen levels will persist above 1% of the current level for approximately 1.080 ± 0.140 billion years. This conclusion was reached through simulations that integrated biochemical processes, carbon cycles, and climate mechanisms.
The simulations took into account factors such as increasing solar exposure, rock weathering, and CO2 depletion. As the sun becomes brighter, the chemical balance of the Earth's atmosphere is expected to change, affecting processes like photosynthesis.
The atmosphere is expected to reach a state similar to that of the early Earth, before the Great Oxidation Event.
The research indicates a significant shift in the Earth's atmosphere, with potentially drastic consequences for the planet's ecosystem.
Author's summary: Earth's oxygen may disappear sooner than expected.
