Europe, the world's fastest-warming continent, has been ravaged by record-breaking heat and destructive wildfires this summer, with France and Spain particularly hard hit.
The focus of the heatwave has shifted, with Italy placing most of its major cities under a red heat alert as temperatures climbed to about 40C in some areas.
The heat prompted the Vatican to move Pope Leo's first weekly general audience after the July break indoors rather than hold it in St Peter's Square.
Visitors to Rome welcomed the decision as they sought relief from the sweltering conditions.
"I suppose it's better to hold it indoors because of the heat," a tourist from Mexico, Diego Amaya, said.
Hungarian companies and households cut power consumption this week after a government appeal to ease pressure on the grid amid the severe drought.
The capital Budapest is braced for the peak of the heatwave on Wednesday and Thursday, with temperatures of 40C to 42C expected.
Record-low water levels on the Danube have forced Hungary to largely shut down its sole nuclear plant, which uses the river's waters for cooling, creating an energy crisis that has stretched power supply capacity to its limits.
In southern Albania's Mallakaster, wildfires forced the evacuation of about 15 families along with their livestock and pets, while ground and aerial crews fought to stop the flames reaching homes near a village.
Efforts continued to tame another wildfire, likely caused by lightning, in rocky mountainous terrain south of the Albanian city of Gjirokaster.
In neighbouring Greece, a wildfire possibly caused by vibrating electricity conductors and fanned by gale-force winds has burned thousands of hectares of farmland near a popular holiday destination northwest of Athens.
The blaze appeared largely contained on Wednesday, but hundreds of firefighters remained in the area to prevent flare-ups as six helicopters doused scattered smoking spots.
The hot, dry summer is taking a heavy toll on agriculture.
Britain's cereal harvest is on track to be the worst since comparable records began in 1984, according to an analysis published on Wednesday, as crops wither after one of the driest and hottest spring-summer periods on record.
