Figure 4. Projections of temperature distribution and excess acute heat illnesses under 4 adaptation scenarios (A) SSP1-2.6, (B) SSP 2-4.5, (C) SSP3-7.0, and (D) SSP5-8.5. The top of each panel shows the temperature distribution, and the bottom of each panel shows the distribution of excess acute heat illnesses expressed as the fraction of additional cases (%) attributed to nonoptimal temperature compared with the minimal morbidity temperature (15.5 °C). The gray area is the period of 2010‐2019, and the green area is 2090‐2099. The vertical dashed line on the right is the threshold of nonoptimal temperature (27 °C). SSP: shared socioeconomic pathway.
