Short summary
Soil organic carbon can be used for climate reconstruction and carbon cycle study. This work assessed the effect of temperature on surface soil δ13C by an investigation from 27 sites across a temperature gradient along an isohyet. This study shows that soil type and vegetation type had influences on soil δ13C, while temperature was not related to soil δ13C. This suggests that organic carbon isotopes in sediments cannot be used for the paleotemperature reconstruction.
