Middle to Late Paleozoic Atmospheric CO 2 Levels from Soil Carbonate and Organic Matter

Mora, Claudia I., Driese, Steven G., Colarusso, Lee Ann·1996·Science

Abstract

The stable carbon isotope compositions of ancient soil carbonate and coexisting soil organic matter indicate that atmospheric CO 2 levels decreased by a factor of 10 during the middle to late Paleozoic era. Proxy measurements of CO 2 were made by application of a soil carbonate CO 2 paleobarometer to a suite of paleosols that share key physical and chemical characteristics. The estimates agree with theoretical models that imply that a decrease in Paleozoic atmospheric CO 2 levels was associated with afforestation of the land surface by terrestrial plants and with global climate change leading to the extensive Permo-Carboniferous glaciation.

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

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • The substantial decreases in atmospheric CO2 over geological time, especially during the Devonian and more gradually since the Cretaceous, have largely been effected via the production of deep-rooted trees and the rise of angiosperms, respectively.

    “Certainly it is recognized that the substantial ( possibly 10-or even 20-fold) decreases in atmospheric CO 2 over geological time, especially during the Devonian (416 .0 -359 . 2 Ma) and more gradually since the Cretaceous (145 .5-65 .5 Ma), have largely been effected via the production of deep-rooted trees and the rise of angiosperms, respectively (Mora et al., 1996;Berner, 1997;Berner and Kothav”

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.
