  1. Median, mean, minimum, and maximum for each scenario group are shown for each variable. In the final two rows, the F-statistic from a one-way ANOVA test is shown for the “all scenarios” group, indicating the magnitude of variation between warming group means for each variable across all 177 scenarios. Statistical significance of the F-statistic is indicated by p-values (bottom row;p-values <0.05 indicate that the variation between warming groups is statistically significant).
