  • For pure clear-sky CO2-H2O atmospheres under early Martian conditions, modern radiative-convective models obtain mean surface temperatures of 225 K or less.

    “Hence for pure clear-sky CO 2 -H 2 O atmospheres under early Martian conditions, modern radiativeconvective models obtain mean surface temperatures of 225 K or less (Wordsworth, Forget & Eymet 2010; Ramirez et al. 2014; Halevy & Head 2014).”

    From The Climate of Early Mars (2016) · cites this paper as Ramirez et al. 2014

    In “Greenhouse warming by models that include H2,” the paper reports that its H2-free model reached up to 230 K, above the claimed ceiling of 225 K; it identifies ~225 K as a previously published result. The supplemental “Climate Model Description” reports that a revised solar calculation raised the baseline 5% N2 case to 246 K. The paper supports the broader point that CO2–H2O alone did not produce warm conditions, but not the stated temperature limit. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

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.
