Earth s surface environments are highly oxygenated - from the atmosphere to the deepest reaches of the oceans, representing a hallmark of active photosynthetic biosphere. 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.
