measured using modern isotope ratio mass spectrometry, which has the capability of measuring 13C/12C in atmospheric CO2 to better than 1 part in 105 (Ferretti et al., 2000). Data presented in Figure 2.3 for the 13C/12C ratio of atmospheric CO2 at Mauna Loa show a decreasing ratio, consistent with trends in both fossil fuel CO2 emissions and atmospheric CO2 mixing ratios (Andres et al.,2000; Keeling et al., 2005). 2. ↑ chapitre 7 ([pdf] lire en ligne [archive]), Frequently Asked Question 7.1, p
