Palaeoclimatology: Archaean atmosphere and climate
Nature.

Abstract
Ohmoto et al. argue that carbon dioxide was abundant in the late Archaean and early Proterozoic atmosphere and that methane was probably scarce, based on a reanalysis of the occurrence of siderite, FeCO3, in ancient rocks. Here I consider several factors that may undermine their conclusions.
