No climate paradox under the faint early Sun
It has been inferred that, during the Archaean eon, there must have been a high concentration of atmospheric CO2 and/or CH4, causing a greenhouse effect that would have compensated for the lower solar luminosity at the time and allowed liquid water to be stable in the hydrosphere. Here it is shown, however, that the mineralogy of Archaean sediments is inconsistent with such high concentrations of greenhouse gases. Instead it is proposed that a lower albedo on the Earth helped to moderate surface temperature.
