Earth's Oxygen Depletion: A Sooner Reality
Scientists confirm that Earth's oxygen will disappear much sooner than anticipated.
A study published in Nature Geoscience by Kazumi Ozaki and Christopher T. Reinhard reveals that oxygen levels will persist above 1% of the current level for approximately 1.080 ± 0.140 billion years.
To reach this conclusion, simulations were conducted using models that integrate biochemical processes, carbon cycles, and climate mechanisms, considering factors such as increasing solar exposure, rock weathering, and CO2 depletion.
As the sun becomes brighter, the chemical balance of the Earth's atmosphere will change, affecting processes like photosynthesis, ultimately leading to an atmosphere similar to that of the early Earth, before the Great Oxidation Event.
Earth's oxygen could run out, according to the study.
Author's summary: Earth's oxygen will disappear sooner than thought.
