Abstract

It has been hypothesized that predecessors of today’s bryophytes significantly increased global chemical weathering in the Late Ordovician, thus reducing atmospheric CO 2 concentration and contributing to climate cooling and an interval of glaciations. Studies that try to quantify the enhancement of weathering by non-vascular vegetation, however, are usually limited to small areas and low numbers of species, which hampers extrapolating to the global scale and to past climatic conditions. Here we present a spatially explicit modelling approach to simulate global weathering by non-vascular vegetation in the Late Ordovician. We estimate a potential global weathering flux of 2.8 (km 3 rock) yr−1, defined here as volume of primary minerals affected by chemical transformation. This is around three times larger than today’s global chemical weathering flux. Moreover, we find that simulated weathering is highly sensitive to atmospheric CO 2 concentration. This implies a strong negative feedback between weathering by non-vascular vegetation and Ordovician climate.

  • The radiation of land plants must have had an impact on weathering processes and global chemical fluxes and subsequently on pCO2 and pO2 values in the early Palaeozoic.

    “it appears evident that the radiation of land plants must have had an impact on weathering processes and global chemical fluxes (e.g., Algeo et al., 2001; Porada et al., 2016) and sub­ sequently on the p CO2 and p O2 values in the early Palaeozoic (e.g., Lenton et al., 2012, 2018; Edwards et al., 2017).”

    The Discussion (page not provided) suggests that the evolutionary radiation of primitive land plants could have increased the Ordovician weathering flux, supporting the link to weathering and global chemical fluxes. It presents that increase as a possibility, however, rather than the necessary impact asserted by “must have.” The subsequent pCO2 and pO2 clause carries different citations and is not attributed to this source here.

  • We estimate much higher global NPP and weathering potential than previous arguments.

    “However, we estimate much higher global NPP (Fig. 2) and weathering potential (32).”

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.
