18-month-old baby dies in a car in France: the fourth such death since Monday. 41.3 degrees in Germany: a record high
45 per cent of the 854 towns analysed in a study covering 30 European countries have broken, or are expected to break, their all-time record for Wbgt (Wet Bulb Globe Temperature) by June.
Key points
- France: 55 people have drowned since the start of the heatwave
- Paris: Pride postponed
- Scorching heat in France: a further 2,000 emergency beds for the homeless
- French Minister of the Interior to prefects: ban the sale of alcohol
- UK: Several hospitals in chaos declare a state of emergency
- Germany in the grip of a heatwave with temperatures exceeding 40 degrees
- Twenty tonnes of ice delivered to the Paris fire brigade to help combat the heatwave
- Swiss Beznau nuclear power station shut down due to heat
45 per cent of cities in 30 European countries have already exceeded – or are expected to exceed – historic peak levels of heat stress. The extreme heatwave in June, which is currently breaking records across Western Europe, would have been impossible just a few decades ago. This is according to research by World Weather Attribution (WWA), an international network of climate scientists from various institutions, including the Centre for Environmental Policy, Imperial College London, the Royal Netherlands Meteorological Institute and the Red Cross Red Crescent Climate Centre (Red Cross).
45 per cent of the 854 towns analysed across 30 European countries have broken, or are expected to break, their all-time record for Wbgt (Wet Bulb Globe Temperature) towards the end of June.
The WBGT is an indicator of heat stress and the body’s ability to cool itself through the evaporation of sweat.
The combination of high temperatures and high humidity is particularly dangerous. Both the daytime highs and the night-time temperatures recorded during this heatwave would have been virtually impossible at this time of year even as recently as 1976 – just 50 years ago. A similar heatwave, had it occurred in that historical climate context, would have recorded temperatures 3.5°C lower.
The stifling night-time temperatures that are keeping many people awake this week are now around 100 times more likely than they were just 23 years ago, during the infamous 2003 European heatwave. The likelihood of daytime peaks of this magnitude occurring is around 10 times greater.
