Tomkins et al. [A. G. Tomkins et al., Nature 533, 235–238 (2016)] suggested that iron oxides contained in 2.7-Ga iron micrometeorites can be used to determine the concentration of O2 in the Archean upper atmosphere. Specifically, they argued that t

Explaining the evidence for surface liquid water on early Mars has been a challenge for climate modelers, as the sun was ∼ 30% less luminous during the late-Noachian. We propose that the additional greenhouse forcing of C O 2 - H 2 collision-induce

Recently, Poulsen et al. [2015] suggested that O2 has played a major role in climate forcing during the Phanerozoic. Specifically, they argued that decreased O2 levels during the Cenomanian stage of the mid-Cretaceous (94-100 Ma) could help explain t
