Figure 3. Increase in 20-summer return levels.

(a) Med_warm, and (b) Glob_warm experiment compared to control experiment. Red box denotes study region for area average and further analyses (15–22°E, 46–51°N). Increase of mean threshold excess (beyond 95th percentile of all summer days in the respective experiment) of box average (control: 12.3 mm/day, Med_warm: 13.8 mm/day) is 12.2% and highly significant (p-value < 0.0005).
