Köhler, Peter (2016): Using the Suess effect on the stable carbon isotope to distinguish the future from the past in radiocarbon. In: Environ. Res. Lett. 11 (12), S. 124016. DOI: 10.1088/1748-9326/11/12/124016.

„The depletion of ¹⁴C due to the emission of radiocarbon-free fossil fuels (¹⁴C Suess effect) might lead to similar values in future and past radiocarbon signatures potentially introducing ambiguity in dating. I here test if a similar impact on the stable carbon isotope via the ¹³C Suess effect might help to distinguish between ancient and future carbon sources. To analyze a wide range of possibilities, I add to future emission scenarios carbon dioxide reduction (CDR) mechanisms, which partly enhance the depletion of atmospheric ${{rm{Delta }}}^{14}{rm{C}}$ already caused by the ¹⁴C Suess effect.“
