A model for atmospheric CO 2 over Phanerozoic time
Open accessAbstract
A new model has been constructed for calculating the level of atmospheric CO{sub 2} over Phanerozoic time which is much simpler mathematically than the BLAG model, but more complex geologically and biologically. Results suggest that there has been a notable pattern of varying atmospheric CO{sub 2} level over the past 570 my with high levels during the Mesozoic and early Paleozoic and low levels during the Permo-Carboniferous and late Cenozoic. Sensitivity analysis shows that, within reasonable limits of the principal governing parameters, this qualitative trend of varying CO{sub 2} is relatively insensitive to the actual values chosen for these parameters. Causes of the CO{sub 2} variation are multiple, and no single geological or biological process can be called upon to explain all CO{sub 2} variation for all time. The calculated trend of CO{sub 2} over time agrees well with independent estimations of paleoclimates. Thus, the greenhouse theory of paleoclimate on a long geological time scale is supported by the results of the present study.

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.
