Abstract

Wang et al. (Science 370, 1295–1300, 2020) report a significant decline in CO$_2$ fertilization effects using photosynthesis proxies from long-term satellite records. We find that small systematic biases in AVHRR data impact their analysis to the degree that the key finding is not robust.
