Response to Comments on "Recent global decline of CO₂ fertilization effects on vegetation photosynthesis"

Our study suggests that the global CO₂ fertilization effect (CFE) on vegetation photosynthesis has declined during the past four decades. The Comments suggest that the temporal inconsistency in AVHRR data and the attribution method undermine the results’ robustness. Here, we provide additional evidence that these arguments did not affect our finding and that the global decline in CFE is robust.
