No climate paradox under the faint early Sun

Abstract

Environmental niches in which life first emerged and later evolved on the Earth have undergone dramatic changes in response to evolving tectonic/geochemical cycles and to biologic interventions, as well as increases in the Sun's luminosity of about 25 to 30 per cent over the Earth's history. It has been inferred that the greenhouse effect of atmospheric CO(2) and/or CH(4) compensated for the lower solar luminosity and dictated an Archaean climate in which liquid water was stable in the hydrosphere. Here we demonstrate, however, that the mineralogy of Archaean sediments, particularly the ubiquitous presence of mixed-valence Fe(II-III) oxides (magnetite) in banded iron formations is inconsistent with such high concentrations of greenhouse gases and the metabolic constraints of extant methanogens. Prompted by this, and the absence of geologic evidence for very high greenhouse-gas concentrations, we hypothesize that a lower albedo on the Earth, owing to considerably less continental area and to the lack of biologically induced cloud condensation nuclei, made an important contribution to moderating surface temperature in the Archaean eon. Our model calculations suggest that the lower albedo of the early Earth provided environmental conditions above the freezing point of water, thus alleviating the need for extreme greenhouse-gas concentrations to satisfy the faint early Sun paradox.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Siderite in Archean IFs has been proposed as a pCO2 proxy if it precipitated in equilibrium with the atmosphere.

    “Siderite (FeCO3) in Archean IFs has been proposed as a pCO2 proxy if it precipitated in equilibrium with the atmosphere (170, 171).”

    From The Archean atmosphere (2020) · cites this paper as [170]

  • Some FYS hypotheses invoke clouds: that the Archean Bond albedo was low because of substantially different cloud cover or that abundant high-altitude cirrus clouds warmed early Earth.

    From The Archean atmosphere (2020) · cites this paper as [170]

  • The results are inconsistent with a late Archean pCO2 significantly higher than today as argued by Rosing et al. (2010), since rapid atmospheric escape would be unavoidable in that scenario.

    “Our results are inconsistent with such a low pCO 2 since rapid atmospheric escape would be unavoidable in this scenario.”

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.
