Similarities in trend between atmospheric CO2 concentration changes (orange), the net terrestrial sink from the Global Carbon Project (black), and the modeled CO2 effect on net biome production from TRENDY (red) suggest that ecosystem responses to CO2 have played a role in increasing land carbon uptake over the last 150 y. The TRENDY and GCP data were averaged to 10-y intervals. Sign convention as in Fig. 1.
