Carbon dioxide emissions from Deccan Volcanism and a K/T boundary Greenhouse Effect
Abstract
A greenhouse warming caused by increased emissions of carbon dioxide from the Deccan Traps volcanism has been suggested as the cause of the terminal Cretaceous extinctions on land and in the sea. We estimate total eruptive and noneruptive CO 2 output by the Deccan eruptions (from 6 to 20 × 10 16 moles) over a period of several hundred thousand years based on best estimates of the CO 2 weight fraction of the original basalts and basaltic melts, the fraction of CO 2 degassed, and the volume of the Deccan Traps eruptions. Results of a model designed to estimate the effects of increased CO 2 on climate and ocean chemistry suggest that increases in atmospheric pCO 2 due to Deccan Traps CO 2 emissions would have been less than 75 ppm, leading to a predicted global warming of less than 1°C over several hundred thousand years. We conclude that the direct climate effects of CO 2 emissions from the Deccan eruptions would have been too weak to be an important factor in the end‐Cretaceous mass extinctions.

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.
