Abstract: Elevated CO₂ concentrations increase photosynthesis and, potentially, net ecosystem production (NEP), meaning a greater CO₂ uptake. Climate, nutrients and ecosystem structure, however, influence the effect of increasing CO₂. Here we analysed global NEP from MACC-II and Jena CarboScope atmospheric inversions and ten dynamic global vegetation models (TRENDY), using statistical models to attribute the trends in NEP to its potential drivers: CO2, climatic variables and land-use change. We found that an increased CO2 was consistently associated with an increased NEP (1995–2014). Conversely, increased temperatures were negatively associated with NEP. Using the two atmospheric inversions and TRENDY, the estimated global sensitivities for CO₂ were 6. 0 ± 0. 1, 8. 1 ± 0. 3 and 3. 1 ± 0. 1 PgC per 100 ppm (~1 °C increase), and −0. 5 ± 0. 2, −0. 9 ± 0. 4 and −1. 1 ± 0. 1 PgC °C⁻¹ for temperature. These results indicate a positive CO₂ effect on terrestrial C sinks that is constrained by climate warming.
