Comment on "Modelling the seasonal contribution of a CO2 fertilization effect of the terrestrial vegetation to the amplitude increase in atmospheric CO2 at Mauna Loa Observatory" by G. H. Kohlmaier et al.*

Abstract

Kohlmaier et al. (1989) present a detailed analysis of the increasing amplitude of the atmosphere's seasonal CO₂ cycle at Mauna Lao, Hawaii, finding that the aerial fertilization effect of atmospheric CO₂ enrichment on the terrestrial biota accounts for only about a quarter of the observed amplitude increase between 1958 and 1987.
