The use of AC in France is also quite foreign. None person in my family use one, despite them living all over the country. But go to the states or to India, and there is AC everywhere.
When I grew up in India AC was actually almost nonexistent (except for very rich people and some offices). Instead there were lots of trees, high-velocity ceiling fans, and ventilation (which is important when there's no electricity). Heatstroke/sunstroke outdoors was known, but deaths from hot conditions indoors were rare.
Today, there's fewer trees and a lot more AC. It's ironic because AC (especially inefficient window units) contributes to global warming in a big way.
There will probably be a period of adjustment here in San Francisco, CA, too. My apartment does not have an air conditioner, and neither do many (most?) other SF apartments. If people start dropping dead because of the heat here, I have no idea what the city could/would do to address that situation.
