Biogenic Methane Hydrogen Escape and the Irreversible

The low O2 content of the Archean atmosphere implies that methane should have been present at levels ∼102 to 103 parts per million volume (ppmv) (compared with 1 7 ppmv today) given a plausible biogenic source CH4 is favored as the greenhouse gas that countered the lower luminosity of the early Sun But abundant CH4 implies that hydrogen escapes to space (↑space) orders of magnitude
