An intense heat wave that has roasted Italy, has now pushed northward toward the popular tourist destination of Florence on Friday as wildfires continued to rage in the south of the country. Meanwhile, Spain seemed set to break an all-time record as temperatures shot to hellish points with another heat wave baking southern Europe.

Italy saw temperatures in places upwards of 40 degrees Celcius (104 degrees Fahrenheit), and Rome broiled. By late afternoon Friday, the heat in Florence reached 39 degrees Celcius. That city and Bologna also were issued alerts for Saturday by the health ministry.

Giancarlo Penza, of the Rome-based Catholic charity Sant'Egidio Community, reminded viewers of state TV that the most vulnerable in such weather are elderly people living alone and the homeless.

"(The latter) are the persons who are invisible, who live on the street," Penza said. "Knock on the door of an older person" who lives alone, next door, or "stop someone on the street" without a home and ask if they need help, he urged Italians.

Many southern European countries have suffered days of intense heat, accompanied by deadly wildfires in Algeria, Turkey, Italy and Greece.

While the area is known for its sunny, hot summers, scientists voice little doubt that climate change from the burning of coal, oil and natural gas is driving extreme events such as heat waves, droughts and wildfires. Such hardships are likely to happen more frequently as Earth continues to warm, they say.

Wildfire problems will only worsen because of the abandonment of rural areas and climate change, the environment minister of Cyprus said. The eastern Mediterranean, where the island nation is located, is a "global climate change hot spot," where biodiversity and forest ecosystems are "intensely negatively impacted," Minister Costas Kadis told The Associated Press (AP) Friday.

Unworked agricultural land is being overrun by wild growth, making it easy terrain for fires, which are ever "more intense, destructive and frequently occurring" as a result of more frequent and longer heat waves and droughts, the minister said.

Italian Premier Mario Draghi sent his emergency chief to Calabria in the south, where blazes burning for days in the rugged Aspromonte forest have claimed four lives.

Draghi pledged government aid for those losing property or businesses and an "extraordinary plan of reforestation."

Wildfires on the Italian island of Sardinia were reported largely contained, but a blaze early Friday near Tivoli in the countryside east of Rome forced the evacuation of 25 families. Tivoli's 16th-centruy Villa d'Este and the ancient ruins of Hadrian's Villa are tourist attractions.

Italian firefighters were also battling blazes near Mount Etna, the volcano in Sicily which for months has been belching flames and lava. Authorities said fires erupted in separate locations in the woods, raising suspicions they were caused by people, either deliberately or by accident.

On Greece's second-largest island of Evia, where devastating blazes in the wake of an exceptional heat wave this summer have been described as the nation's worst ecological disaster in decades, a fresh fire broke out on Friday.

Spain's state meteorological agency registered 45 degrees Celsius at Granada airport at 3 p.m.

Elsewhere in Spain's sizzling south, in the city of Malaga, Juan Villodres was doing a brisk trade selling cold drinks from a kiosk. "The heat wave this year is getting more intense, and the last one this strong was in 2019,'' Villodres said.

Spain was bracing for even hotter weather. Temperatures as high as 47 degrees Celsius are forecast in the south on Saturday. That would break a national record of 46.9 degrees Celsius, set in Cordoba in July 2017.

On Wednesday, the Italian town of Floridia near the city of Syracuse in Sicily reported a temperature reading of 48.8 degrees Celsius.

On Friday, a World Meteorological Organization official said at a briefing in Geneva that it could take a month or two to verify the reading and determine if it's indeed a record for continental Europe, topping the previous 48 degrees Celsius set in Athens in 1977.

France's national weather agency warned of temperatures as high as 40 degrees Celsius on Friday and Saturday in the Provence region, near the border with Italy.

Temperatures in Portugal on Saturday and Sunday were forecast to climb into the 40s. In much of the country, with a significantly increased risk for wildfires, the public has been barred from entering forested areas and is banned from using fireworks or farm machinery that could cause sparks.

In Serbia, the army has deployed water tanks and authorities have appealed to residents to avoid watering gardens. A weeks-long drought is worrying cattle owners, particularly in remote villages in hilly areas.
