The graphic above is associated with an article by John Burn Murdoch in the Financial Times (12th July 2025).
With climate change, there are more hot days. When temperatures rise above 30C mortality rises significantly. This can be mitigated, and as the graph shows, is in some countries by air conditioning. Notably the graph compares mortality against rising temperatures in locations (in the US) that have a high incidence of air conditioning against those in Europe that do not. The difference is significant.
The article notes that while the impact of some air conditioning systems can add to climate change, the impact of hot temperatures is now such that finding ways to implement air conditioning that does not promote climate change (this does now exist) is becoming urgent.
File under really useful knowledge, something the FT is quite good at
