I live in a temperate climate and used my Air Conditioner only ten days in the past year. Five of those days were hot enough to kill. Even in down-right cold areas, Air Conditioners (ACs) still greatly improve quality of life.
Over the past few years, there have been several pop-sci articles in high-profile magazines using the same IEA projections that I use here but focused on the irony that space cooling contributes to climate warming. They usually imply a feedback loop where global temperatures are driving ACs use while AC use increases climate change in a death spiral.
This, thankfully, is not accurate. Climate change is not the primary driver of increased AC use — improved equipment affordability is. Here’s a graph from IEA showing the percentage of homes with AC ownership by country as of 2016:
