Europe has more heat deaths per year than the United States loses to gun deaths

A/C, fans, shade, public misting stations, and maybe a special phone line for people (elderly mostly?) who are suffering. There's a lot society could do to prevent these deaths.

Unfortunately they won't as it appears to be a mindset thing of especially central Europe to be anti-AC (with the exception of cars).

I would also take the number of heat-related deaths with a grain of salt...
