Record-Setting Heat Waves Sweep Europe Lisa Schlein GENEVA - Much of Europe is getting hit with a record-setting heat wave. The World Meteorological Organization is concerned not just because of the temperatures, but because the summer heat is a month earlier than usual and more intense. It is likely another sign of climate change. Europe is wilting from the warm air masses coming from Africa, bringing with them Saharan heat and, in some cases, Saharan dust. The World Meteorological Organization said temperature records have been broken this week in France, Spain, Germany, Austria and Switzerland. On Friday, France issued red alerts for four areas in the south as temperatures reached an all time high of 45.1 Celsius (113 Fahrenheit). While this spate of new maximum daytime records is of concern, WMO spokeswoman Claire Nullis said the increasing number of minimum overnight temperature records is particularly worrisome. "I stress the overnight records are important because night time is when our bodies recover," Nullis said. "It is when plants and animals recover. So, if we are seeing minimum overnight temperatures of 25 degrees C (77 Fahrenheit) as we have done in some places, it is not good news." Heat events kill thousands of people every year. They often trigger secondary events such as wildfires and electrical grid failures. .
