This paper investigates the changes in country-level energy demand for cooling over the past two decades (2000-2021). Using a new database jointly generated by CMCC and IEA, the study analyzes cooling degree days (CDDs), considering population weighting and humidity. Results show a general increase in CDDs worldwide, leading to higher energy consumption for cooling. The study also examines the temporal clustering of CDDs, revealing that intense CDD periods tend to cluster, particularly in emerging countries like India, Cambodia, Thailand, and Vietnam, where the impact of humidity is more pronounced.
