Abstract

Surface temperature is a fundamental parameter of Earth’s climate. Its evolution through time is commonly reconstructed using the oxygen isotope and the clumped isotope compositions of carbonate archives. However, reaction kinetics involved in the precipitation of carbonates can introduce inaccuracies in the derived temperatures. Here, we show that dual clumped isotope analyses, i.e., simultaneous ∆47 and ∆48 measurements on the single carbonate phase, can identify the origin and quantify the extent of these kinetic biases. Our results verify theoretical predictions and evidence that the isotopic disequilibrium commonly observed in speleothems and scleractinian coral skeletons is inherited from the dissolved inorganic carbon pool of their parent solutions. Further, we show that dual clumped isotope thermometry can achieve reliable palaeotemperature reconstructions, devoid of kinetic bias. Analysis of a belemnite rostrum implies that it precipitated near isotopic equilibrium and confirms the warmer-than-present temperatures during the Early Cretaceous at southern high latitudes.

    “If the magnitude of the offset is small enough, accurate formation temperatures can potentially be reconstructed based on modeled disequilibrium slopes (Bajnai et al. 2020, Guo 2020, Fiebig et al. 2021).”

  • A similar positive offset of Δ47 compared to the values reported in Bernasconi et al. (2018) has also been reported in Fiebig et al. (2019), Bajnai et al. (2020), and Thaler et al. (2020).

    “A similar positive offset of Δ47 compared to the values reported in Bernasconi et al. (2018) has also been reported in Fiebig et al. (2019), Bajnai et al. (2020), and Thaler et al. (2020).”

    The Results (Table 1; page unavailable) report Bajnai et al.’s Δ47 values for ETH reference materials, but do not compare them with Bernasconi et al. (2018). A search for Bernasconi found a reference-list entry, not a passage establishing the claimed positive offset. (LLM, conf=0.72)

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.
