Abstract
Nie and colleagues suggest a key role for interannual climate variation as an explanation for the temporal dynamics of an unexpected 20-year reversal of biomass responses of C<sub>3</sub>-C<sub>4</sub> grasses to elevated CO<sub>2</sub> However, we had already identified some climate-dependent differences in C<sub>3</sub> and C<sub>4</sub> responses to eCO<sub>2</sub> and shown that these could not fully explain the temporal dynamics we observed.
