Highly reduced gases such as CH4 or NH3 are dissociated by photolysis due to the high XUV flux of the young Sun and by reactions with OH and O radicals produced from the photolysis of H2O and CO2.
“Highly reduced gases such as CH 4 or NH 3 are also dissociated by photolysis due to the high XUV flux of the young Sun and by reactions with OH and O radicals produced from the photolysis of H 2 O and CO 2 molecules (Kuhn and Atreya 1979; Kasting 1982; Kasting 1993; Zahnle et al. 2010; Wordsworth 2016).”

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.
