Italy baked in sweltering temperatures that continued to drive deadly wildfires on Wednesday, with Spain and Portugal bracing for the arrival of a dangerous heatwave that has grilled south-eastern Europe and is starting to push west toward the Iberian peninsula.
A heatwave fed by hot air from North Africa has engulfed large parts of the Mediterranean region in recent days, contributing to massive wildfires and killing dozens of people in Italy, Turkey and Algeria.
In Greece, huge wildfires have ravaged forests for a week, destroying homes and forcing evacuations.
Sicily recorded on Wednesday what may be a new European temperature record, though weather experts cautioned that the measurement still must be confirmed.
The Sicily region’s agriculture-meteorological information service, SIAS, reported that a temperature of 48.8C (119.84F) was reached at the island’s Syracuse station.
The agency said on its Facebook page it is the highest temperature registered in the entire network since its installation in 2002.
The highest temperature ever recorded on the European continent is 48C (118.40F) in 1977 in Athens.
The Sicily temperature could not be independently confirmed, however, and Italy’s air force meteorological service said it had not recorded temperatures approaching that high on Wednesday but that its stations are in other locations so variations are to be expected.
The World Meteorological Organisation (WMO) said it would examine the reading but Randy Cerveny, the agency’s rapporteur for weather records, called it “suspicious, so we’re not going to make any immediate determination”.
“It doesn’t sound terribly plausible,” he said. “But we’re not going to dismiss it.”
WMO spokeswoman Sylvie Castonguay counselled caution: “Extreme weather and climate events are often sensationalised and mischaracterised as ‘records’ before they have been thoroughly investigated and properly validated.”
However, the high-pressure system of near-record strength currently centred over the Mediterranean is the type that can produce unprecedented heat somewhere, meteorologist Jeff Masters of Yale Climate Connections said.
North Africa is also flirting with all-time high temperatures, he said.
Spain and Portugal could see what was heading their way, as temperatures on the Iberian peninsula were forecast to start building from Thursday.
Portugal’s prime minister warned that the hot weather increases the threat of wildfires, which in 2017 killed more than 100 people in his country.
Spain’s weather service forecast a heatwave through Monday and said temperatures could surpass 44C (111F) in some areas.
“The maximum and minimum temperatures will reach levels far above the normal for this time of the year,” Spain’s weather service, AEMET, said in a “special weather warning”.
Such peaks of temperature are not unheard of in Spain and Portugal during the summer months. Even so, climate scientists say there is little doubt climate change from the burning of coal, oil and natural gas is driving extreme events, such as heatwaves, droughts, wildfires, floods and storms.
Researchers can directly link a single event to climate change only through intensive data analysis, but they say such calamities are expected to happen more frequently on our warming planet.
Portuguese Prime Minister Antonio Costa urged people to take special care amid the scorching weather and wildfire danger, adding that many wildfires start with careless behaviour.
Mr Costa said “the terrible images” from Greece and Turkey in recent days brought back Portuguese memories of 2017.
“We don’t want to see that scenario here again,” Mr Costa said in a videotaped message at his official residence.
Portuguese authorities say they can deploy more than 12,000 firefighters, some 2,700 vehicles and 60 aircraft during the summer season.
Mr Costa said that over the past three years Portugal has reduced by half the number of wildfires compared with the average of the previous 10 years and cut the charred area by 64%.
Authorities enacted a broad range of measures after 2017. They included better forest management, including woodland clearance projects and technical support for people living in rural areas, opening thousands of miles of firebreaks and reacting more rapidly to outbreaks with special firefighting units.
Nobody has died in forest blazes in Portugal since 2017.
