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

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • Mass-balance calculations give 10 to 50 PAL of CO2 at 2.7 Ga ago and 23÷3×3 PAL of CO2 at 2.2 Ga ago.

    “Mass-balance calculations give 10 to 50 PAL of CO2 at 2.7 Ga ago and 23÷3×3 PAL of CO2 at 2.2 Ga ago (42, 168).”

    From The Archean atmosphere (2020) · cites this paper as [42]

  • These analyses assume that all the CO2 that entered the soils caused dissolution.

    “However, these analyses assume that all the CO2 that entered the soils caused dissolution, so pCO2 could have been higher if only a fraction of CO2 had been used.”

    From The Archean atmosphere (2020) · cites this paper as [42]

  • Geochemical measurements from the late Archean suggest that pCO2 was likely significantly higher than in the modern atmosphere, though significant uncertainty exists and no measurements for the early Archean or Hadean are available.

    “Geochemical measurements extend back to the late Archean and suggest that the CO 2 partial pressure (pCO 2 ) was likely significantly higher than in the modern atmosphere (Rye et al. 1995; Hessler et al. 2004; Sheldon 2006; Driese et al. 2011; Kanzaki and Murakami 2015) though significant uncertainty exists and no measurements for the early Archean or the Hadean are available”

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.
