Abstract
Wang <i>et al</i>. (Research Articles, 11 December 2020, p. 1295) reported a large decline in the CO<sub>2</sub> fertilization effect (CFE) on global photosynthesis, on the basis of changing regression coefficients of CO<sub>2</sub> (β) for satellite proxies/products of photosynthesis. We show that their methods cannot robustly estimate CFE, leading to incorrect attribution, and largely neglect CO<sub>2</sub> effects on the photosynthetic enzyme ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO).
