Fig. 6: Contributions of climate change and population change to the changes in non-optimal temperature-related (heat and cold combined) mortality at different levels of global warming.

Country/area-level changes by climate change and population aging are shown at 1.5 °C, 2 °C, and 3 °C of global warming using 20-year window compared with the historical period 1995-2014 under SSP5-8.5. The future periods in which the 20-year running mean of global mean temperature first reaches the 1.5 °C, 2 °C, and 3 °C of warming above pre-industrial level (1850–1900) are 2018–2037, 2032–2051, and 2055–2074, respectively under SSP5-8.5. The impact of population aging was estimated by subtracting the future changes in temperature-related impacts in the constant population scenario (climate-only) from the changes in temperature-related impacts under SSP5 mortality projection in the climate-population scenario.
