FIGURE 3 | Historical and projected evolution of global mean MHW days, by category. Annual time series of the global mean count of moderate (yellow), strong (orange), severe (red), and extreme (dark brown) MHW days are shown for (A) historical and RCP4.5 experiments and (B) historical and RCP8.5 experiments. Note that the total stacked amount is equivalent to the total MHW days, i.e., the lines shown in Figure 1F . The dashed line indicates a full year (365
