Cossy
One of my friends lives in Spain, Costa del Sol. It’s going to be 40c this week, and very hot for at least 6 weeks.
She only goes out very early in the morning and much later in the evening and stays inside days with air con on.
Ditto my friend who lives in Vence, near Nice.
The biggest differences are all their homes, and most of their shops and restaurants have air con, both these ladies have access to big outdoor swimming pools, workers shut down in the middle of the day, all have a siesta for a couple of hours in the hottest part of the day.
Cannot see how that would work here.
It is hard to imagine.
Also in hotter countries families go out late in the evenings and all the shops/cafes/restaurants are open. Because is too hot to go out earlier.
Is a whole different culture.
But in time we may no choice than to develop a different culture in order to survive rising temps.
