Fig. 3: Heat and moist-heat extremes and impacts of different forcings on them.

a–c Multi-model mean absolute values of the 99.9th percentile values of 2-m air temperature (T2m: a), HUMIDEX (HU: b), and wet-bulb temperature (Tw: c) of the first 30 years (1901–1930) in the simulations without irrigation expansion (1901irr). d–l Multi-model mean impacts of all forcings (ALL: greenhouse gas emissions, land use and land management change, irrigation expansion, etc.) (d–f), all forcings except irrigation expansion (ALL-IE: g–i), and irrigation expansion (IE: j–l) on the 99.9th percentile values of T2m (d, g, j), HU (e, h, k), and Tw (f, i, l). Impacts are calculated by subtracting the values in the new exp_period by those in the reference exp_period (see Table 1). Hatches indicate that signals (>0.1 or <−0.1) are agreed by ≥5 of 6 models (results for the individual models are presented in Supplementary Fig. S16–21). Results for other extreme event percentiles (the 99th and 99.5th) are shown in in Supplementary Figs. S28–36.
