Fig. 4: The global adaptation cooling deficit.
From: Inequalities in global residential cooling energy use to 2050
a Cumulative share of the population (pop.) without air-conditioning (AC) in 2050 as a function of Cooling Degree Days yr−1 (CDDs/yr) exposure, by global region and scenario. Vertical dashed lines highlight the population-weighted average CDDs yr−1 in each region under historical climate (1995–2014). b Count of people exposed to more CDDs yr−1 than the regional historical average value and living without AC, by global region and scenario. The numbers refer to projections calculated with the Coupled Model Intercomparison Project Phase 6 (CMIP6) Global Climate Models (GCMs) enemble median (excluding 'hot models'62).
