I've just spent the last three weeks in Poland and the temperature was regularly 30c plus. Everyone just got on with their lives, no freezers broke down in supermarkets, trains ran regularly, the occasional massive thunderstorms caused a few downpours, but nothing catastrophic, and despite having drought conditions, everything worked and was business as usual.
Plus I could wash my car with a hosepipe
It was also interesting that when we drove back over the Rhine the other day, there were barges merrily delivering their goods up and down
Not bad in a country everyone thinks is cold
