Carbon-14 in Methane Sources and in Atmospheric Methane: The Contribution from Fossil Carbon
Abstract
Measurements of carbon-14 in small samples of methane from major biogenic sources, from biomass burning, and in "clean air" samples from both the Northern and Southern hemispheres reveal that methane from ruminants contains contemporary carbon, whereas that from wetlands, peat bogs, rice fields, and tundra is somewhat, depleted in carbon-14. Atmospheric 14 CH 4 seems to have increased from 1986 to 1987, and levels at the end of 1987 were 123.3 ± 0.8 percent modern carbon (pMC) in the Northern Hemisphere and 120.0 ± 0.7 pMC in the Southern Hemisphere. Model calculations of source partitioning based on the carbon-14 data, CH 4 concentrations, and δ 13 C in CH 4 indicate that 21 ± 3% of atmospheric CH 4 was derived from fossil carbon at the end of 1987. The data also indicate that pressurized water reactors are an increasingly important source of 14 CH 4 .

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.
