Biogenic Methane, Hydrogen Escape, and the Irreversible Oxidation of Early Earth

Abstract

The low O 2 content of the Archean atmosphere implies that methane should have been present at levels ∼10 2 to 10 3 parts per million volume (ppmv) (compared with 1.7 ppmv today) given a plausible biogenic source. CH 4 is favored as the greenhouse gas that countered the lower luminosity of the early Sun. But abundant CH 4 implies that hydrogen escapes to space (↑space) orders of magnitude faster than today. Such reductant loss oxidizes the Earth. Photosynthesis splits water into O 2 and H, and methanogenesis transfers the H into CH 4 . Hydrogen escape after CH 4 photolysis, therefore, causes a net gain of oxygen [CO 2 + 2H 2 O → CH 4 + 2O 2 → CO 2 + O 2 + 4H(↑space)]. Expected irreversible oxidation (∼10 12 to 10 13 moles oxygen per year) may help explain how Earth's surface environment became irreversibly oxidized.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
