Figure 1: Percentage yield change as a function of temperature for the three main crops and for temperate and tropical regions for local mean temperature changes up to 5 °C (n = 1,048 from 66 studies).
From: A meta-analysis of crop yield under climate change and adaptation
Shaded bands indicate the 95% confidence interval of regressions consistent with the data based on 500 bootstrap samples, which are separated according to the presence (blue) or absence (orange) of adaptation. Note that four data points across all six panels are outside the yield change range shown. These were omitted for clarity. Supplementary Fig. 4 shows data from across all temperatures and yield ranges.
