Second heat wave in as many weeks grips Mediterranean while fires hit Spain, Switzerland and Greece

Officials are warning residents and tourists packing Mediterranean destinations to stay indoors as a second heat wave in as many weeks hits the region and Greece, Spain and Switzerland battle wildfires. In Italy, Red Cross teams checked on the elderly by phone. In Portugal, they took to social media to warn people not to leave pets or children in parked cars. In Greece, volunteers handed out drinking water, while in Spain they reminded people to protect themselves from breathing in smoke from fires. Several countries in southern Europe are sweating through a new heat wave, amplified by climate change, that is expected to persist for days. The U.N. weather agency said that temperatures in Europe could break even the 48.8-degree Celsius record set in Sicily two years ago.
