Abstract

To the editor: The recent study by Smith et al.1 (hereafter S15) concludes that Earth system models (ESMs) overestimate the effect of CO2 fertilization on net primary productivity (NPP). Whilst this finding is possible2, here we highlight that the satellite derived NPP estimates used are likely to underestimate the CO2 fertilization effect because they do not account for the primary effect of CO2 on photosynthesis. Additionally the calculation of NPP sensitivity to atmospheric CO2 is misleading, invalidating the comparison with free air CO2 enrichment (FACE) data.
