Appendix F1. Yield and growth variables of rice in response to elevated [CO2] at different years. Symbols refer to the weighted percent change at elevated [CO2] with an interval of 95% confidence. The number of studies for each variable is shown next to tick lines. Categorical groups showing statistically significant are illustrated.

Appendix F2. Dependence of rice yield response to warming under elevated [CO2] on ambient temperature. The values of temperature increase for all studies are calculated as the difference in mean daily temperature between warm and ambient treatments. Ambient temperature was categorized into three groups, namely, T20 (17–22 ºC), T25 (24–26 ºC) and T30 (27–32 ºC).
