Anthropogenic CO2 emissions

To the Editor —

Francey et al.1 use atmospheric CO2 measurements to infer an underestimation in 1994–2007 emissions. Here we show that this inference depends on an unrealistic assumption of CO2 sinks and that atmospheric CO2 measurements are not inconsistent with global CO2 emission inventory data2 over the past two decades, given the observational uncertainties.
