13C/12C records in northern hemispheric trees during the past 500 years—Anthropogenic impact and climatic superpositions

Freyer, H. D., Belacy, N.·1983·Journal of Geophysical Research: Oceans

Abstract

13 C/12 C data for the past 500 years are reported on two sets of European oak forest trees from the German Spessart and on free‐standing Scots pine trees from Muddus National Park, Sweden. While the forest trees show large nonsystematic variations in the 13 C/12 C ratio over the 500 years, the free‐standing trees show smaller fluctuations, which can be correlated to climatic changes. Since industrialization of these areas in 1850 A.D., the 13 C/12 C record for the free‐standing trees has been dominated by a systematic decrease of about 2‰, which is comparable with other mean 13 C/12 C tree ring data. The calculated Northern Hemisphere 13 C/12 C record derived from a total of about 50 trees reflects the recent 13 C/12 C change in atmospheric CO 2 observed from 1956 to 1980 A.D.

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.
