Fig. 3: Extreme value analysis.
From: Analysis of the 2024 Hajj heat event and future temperature extremes in Mecca

Based on the Generalized Extreme Value distribution (GEV) and Maximum Likelihood (ML) statistical approaches (see Methods) for the GSOD observations (a) and CESM-WRF-CYI (RCM4) historical simulation (b) and projections for pathways RCP4.5 (c, e) and RCP8.5 (d, f). The 95% confidence intervals (CI) are also indicated. The orange star symbols denote the expected return periods of events with temperatures similar to the June 2024 extreme record (51.8 °C).
