School closures, frozen bananas and faith: Europeans struggle with heatwave

French authorities announced school closures and traffic restrictions as swathes of Europe continued to wither under a powerful heatwave.

Residents and tourists alike cooled off in fountains, rivers and lakes from Paris to Munich as the mercury remained stubbornly in the upper 30˚C. Parts of southern France and Spain recorded temperatures above 40˚C.

French and German authorities warned of water shortages, volunteers handed out bottled water to homeless people in Belgium and in Poland - which recorded its highest ever June temperature on Wednesday of 38.2˚C — the use of fans helped drive power demand to a record high.

"Killer heat events of this kind will become even more widespread by the middle of the century in Europe, but this outlook could get worse unless action is taken to curb future greenhouse gas emissions."

In Paris and Lyon, French authorities imposed traffic restrictions to limit the environmental impact of the heatwave.

Even in Britain, which has so far evaded the heatwave and where music lovers heading to the Glastonbury festival in wellington boots in anticipation of the traditional downpours and muddy fields, meteorologists were predicting a blast of hotter weather at the weekend.
