Fig. 5: Positive correlation between change in HW metrics and temperature.

Relationship between changes in a compound, b daytime, and c nighttime HW frequency (HWs season−1), duration (days HW−1), and intensity (°C HW−1); and changes in daily mean, maximum, and minimum near-surface temperatures (°C), respectively. Changes are computed as “recent period (1985–2014)” minus “historical period (1950–1979)”. The solid line indicates the trend, with shaded areas representing the 95% confidence interval. For each HW metric, the correlation coefficient (denoted as "r") and p value (denoted as "p") are provided in the corresponding label. d–f displays the spatial patterns of the change in corresponding temperature, and hatching indicates grid points where at least 70% of the ensemble members agree on the sign of the trend in the ensemble mean.
