Europe on high alert as surprise early heatwave creeps north
Tens of thousands of people have died in Europe during past heatwaves, prompting authorities to issue warnings for old and young, the sick, and others vulnerable to what experts call a "silent killer".
Scientists said it was unusual for such heat to hit Europe this early in the season, but that human-caused climate change from burning fossil fuels was making these once-rare events far more likely.
Records have tumbled, with France and Portugal experiencing their highest-ever single-day temperatures in June, Spain its warmest June, and the Netherlands its hottest opening day of July.
In England, the weather service said it was the hottest June since records began in 1884.
The Mediterranean Sea recorded a new June high of 26.01 degrees Celsius on Sunday, just the latest abnormal marine heatwave in the basin, harming sea life and turbocharging storms.
The summit of the Eiffel Tower was shut for a second straight day, and was due to remain closed on Wednesday.
On Tuesday in Brussels, the city's Atomium monument, famed for its giant stainless steel balls, was exceptionally shut as temperatures reached 37 degrees Celsius (98 degrees Fahrenheit).
'Living like moles'
Under scorching skies, Paris imposed its first "red alert" in five years, empowering officials to limit or ban sporting events, festivals and school outings for children.
The heat is expected to peak on Tuesday, with Paris facing highs of 38C, but authorities have extended the alert into Wednesday.
Some parks will remain open all night, pools have extended visiting hours, and cooling centres in churches and museums are offering respite from the lack of greenery and concrete surfaces that amplify the heat.
"We're living a bit like moles," Nicole, 85, told AFP in the stifling air of her apartment in a tower block in Paris.
Across France, the government said it expected nearly 1,350 schools to be partially or completely shut, with teachers complaining that overheated and unventilated classrooms were making students unwell.
Authorities are fanning out to check on the elderly, chronically ill and the homeless.
"When it's cold, I add blankets and hats. But when it's hot like this, what can I do? Nothing, just wait for it to pass and hope I don't faint," said Jo, a 55-year-old homeless man in Bordeaux, in southwestern France.
As far north as the Netherlands, some regions were placed on the second-highest alert on Tuesday, with temperatures forecast to reach 38C.
Schools in Rotterdam and across West Brabant province adopted "tropical schedules" to ensure students started and finished earlier to avoid the worst of the day's heat.
In Germany, temperatures could peak at 40C on Wednesday.
In Spain and Portugal, where highs of 46C were recorded in some locations over the weekend, a level of respite was expected, though temperatures could still exceed 40C in parts.
A two-year-old boy died in northeastern Spain on Tuesday after being left in the back of a car parked in the sun, police said.
'Silent killer'
The International Federation of Red Cross and Red Crescent Societies (IFRC) said its teams of volunteers had mobilised across Europe to give out water and assist the most vulnerable.
"Extreme heat doesn't have to be a disaster: knowledge, preparedness and early action make all the difference," said IFRC spokesman Tommaso Della Longa.
"We're still seeing infrastructure challenges associated with heatwaves, pressure on national healthcare systems, and we still have excess deaths," she told AFP.
A heatwave in 2022 killed an estimated 60,000 people across Europe, mostly elderly.
The World Meteorological Organization said Tuesday that heat was a "silent killer" and the death toll from prolonged, extreme exposure was often under-reflected in official statistics.
Spokeswoman Clare Nullis said every death from heat was unnecessary, and society would have to adapt to more heatwaves in future.
"It's something we have to learn to live with," Nullis said.

'I lost my battle': warming sea killing Albania fishing
Albanians like him have lived off the sea for generations, but Kocaj fears his way of life in the Bay of Vlore is coming to an end, with warming waters shrinking his catch every year. "I lost my battle with the sea. I loved it, but it betrayed me," the father of four told AFP. As Europe bakes in the first heatwave of the summer, sea temperatures are climbing too. By the end of June, the sea off the Albanian coast had already reached 25.5 degrees Celsius (77.9 degrees Fahrenheit) — 1.5 degrees higher than it was at this time last year. "My luck deserted me a long time ago," Kocaj said, dejected by his meagre catch. "Look at my almost empty nets," sighed the 65-year-old, as he prepared to return to port. A few years ago, he was still able to provide for his family. But now, he said, he's ruined. "The rising temperatures have been a fatal blow to the fish, and to us too," he added, struggling to hide his tears. Fish have 'almost disappeared' In Vlore, Kocaj estimates fish populations have declined by 70 percent. The situation is no better outside the inlet, where even larger fishing boats in deeper water are struggling, and forecasts are not optimistic. Reshat Xhelilaj, head of the fishing and aquaculture sector in Vlore, told AFP that he expects a hotter summer than 2024, which saw a deep-sea temperature of up to 30.5C (86.9F). Walking down the dock, dragging a small bucket half-filled with fish, Kocaj said that around five years ago he could have returned with up to 10 kilos (22 pounds) of hake per day. Back then, he and his brother fished together. And even with much smaller nets, they brought home enough fish to support both their families. Now he's alone, and despite casting a kilometre of net and spending hours at sea, he is lucky to come back with two kilos of anything. "They've almost disappeared," he said of his once-abundant catch. 'Devastating' "Climate change is a major factor in the decline of fish populations," said Nexhip Hysolokaj, a biology researcher at Tirana's Polis University. Rising temperatures make it difficult for many marine organisms to reproduce and grow, particularly those adapted for cooler waters. At least a dozen species of fish, usually found in the Indian and Pacific oceans, are now crowding out local species that are essential to the food chain, such as the endangered sardine, he said. In Kocaj's catch lies the proof, a highly venomous lionfish, which is common in the Caribbean. "To his misfortune and mine, it ended up in my nets," the fisherman said. The spiny fish is edible if cleaned and prepared correctly, and campaigns are underway to help fishermen turn this tropical invader into a profitable alternative. "Climate change has had devastating effects," warned Captain Baci Dyrmishi, head of the marine fishing association in the bay. "Temperatures are exceeding forecasts, and the waters are overheating." Baci said that as the catch shrinks, the number of those living off the sea is dwindling too, and many are leaving the idyllic coastal city to make a living elsewhere. On the quay at Radhima, once home to over a dozen vessels, only three or four now dock. © 2025 AFP

Cooler temperatures coming to Europe after scorching heatwave
After days of record-breaking heatwaves across Europe, relief will start to arrive from the Atlantic on Wednesday, bringing thunderstorms and cooler temperatures to parts of western Europe. Paris hit 40 degrees Celsius (104 degrees Fahrenheit) on Tuesday, but the high will drop to 35C on Wednesday and to 28C on Thursday, Météo-France forecast. "Our latest forecasts confirm the arrival of cooling from the west on Wednesday, which will quickly affect the northwest of the country," Météo-France said, adding that there could be heavy thunderstorms late Wednesday and Thursday in the east along the German border. Germany 's national weather service is forecasting a peak of 40C on Wednesday in the economic capital Frankfurt, but that will plummet to 27C by Thursday. Spain and Italy, meanwhile, may have to wait for the weekend to see some limited relief. On Tuesday, around 2,200 schools were shut in France because of the heat, but only about 135 are expected to be kept closed Wednesday, the education ministry said. Météo-France said June 30 was the hottest June day since measurements began in 1947, beating out a record set in 2019. Similar records were set Tuesday in Portugal and the Netherlands. "For the continent as a whole, the month is likely to be ranked among the top 5 warmest Junes on record," said the European Centre for Medium-Range Weather Forecasts. On Sunday, in a case of two extremes, the Mediterranean Sea hit a record-high temperature for June while Mont Blanc, the highest peak in Europe, went above freezing, a rarity for this time of year. In Turkey, forest fires that broke out over the weekend around Izmir in the west and Hatay in the south were largely brought under control, authorities said Tuesday evening, though they warned about continued risks from dry, hot winds. 'Silent killer' Tens of thousands of people have died in Europe during past heatwaves, prompting authorities to issue warnings for old and young, the sick, and others vulnerable to what experts call a "silent killer". On Tuesday, police in Spain said a two-year-old died in the country's northeast after being left in a car in the sun for several hours. "Due to climate change caused by humans, extreme heat is becoming more frequent and intense. This is something we must learn to live with," said Clare Nullis, spokesperson for the World Meteorological Organization (WMO), a UN agency based in Geneva. Extreme heat can cause dehydration, muscle cramps, headaches and nausea. The most serious risk is heatstroke, which can lead to death, especially in vulnerable people. Free guided tours of air-conditioned museums in Venice and free access to swimming pools in Rome were offered to protect seniors. According to a report by Allianz Trade on Tuesday, the European economy could lose 0.5 percentage points of growth this year due to recent heatwaves. The health impact will take longer to assess. According to France's Ministry of Health, an initial estimate of excess mortality during the period will be available approximately two weeks after the end of the heatwave, but detailed data based on medical data will not be available until the fall.

Climate change is changing the geography of infectious disease
Europe is unusually hot. Several cities in France have been placed on an 'unprecedented' high alert on Tuesday, Spain recorded a scorching high of 46 degrees Celsius on Monday while wildfires in Turkey caused by a heatwave have forced more than 50,000 people to be evacuated from five regions in the western province of Izmir. While the heat is uncharacteristically strong, extreme weather is no longer a surprise. Science agrees that climate change caused by steadily increasing greenhouse emissions has been the primary factor for the scorching new reality that the world is forced to adapt to, be it heatwaves, floods, droughts or extreme cold. While the cumulative meteorological changes might make life more difficult for people, bacteria, pathogens and viruses are thriving in a world that's getting hotter and more humid. Climate change is bringing 'tropical', climate sensitive illnesses up north, into Europe, shifting the geography of global infectious disease. The migration of disease 'Over half of all infectious diseases confronted by humanity worldwide have been at some point aggravated and even strengthened by climatic hazards,' says Dr Aleksandra Kazmierczak, an expert on the relationship between climate change and human health at the European Environment Agency (EEA). Kazmierczak says that climatic conditions have made Europe more suitable for vector and water borne disease. 'There is a northward, temporal shift because the current climate is more suitable for pathogens. Disease season is longer – ticks, for example, are now active all year round in many places.' One of the fastest growing infectious diseases in Europe is dengue. 304 cases were reported in Europe in 2024 alone – compared to 275 cases recorded in the previous 15 years combined. 05:11 The main culprit behind dengue is the Asian tiger mosquito, or Aedes albopictus. The insect is what's known as a vector, i.e. a living organism that can transmit infectious pathogens between humans or from animals to humans. With its distinctive black and white stripes that resemble those of a zebra more than a tiger, the mosquito is capable of transmitting dengue, zika and chikungunya. Europe only experienced a handful of diseases carried by the tiger mosquito per year right up until the late 90's. Most were one-off cases brought home by travelers from South East Asia – Aedes albopictus' s native home. But with increased travel and globalization, the insect's journeys westward increased. It hopped onto cargo carriers to Albania or hitched a ride to the warmer parts of France and moved to Europe, where it remains to this day. In 2006, France officially declared dengue a notifiable disease. In 2022, its presence was detected in most of the French mainland administrative departments. The insect quickly adapted itself to urban environments, where it needs just one still body of water – an undisturbed pond or a neglected watering can – to reproduce and proliferate. The numbers have jumped so dramatically that scientists now believe that the diseases carried by Aedes albopictus will become endemic in Europe. Some researchers even say that the number of dengue and chikungunya outbreaks could increase five-fold by 2060 compared to current rates. The tiger mosquito is a known carrier of several pathogens and viruses. Climatic conditions have contributed to a geographic range expansion of several other vectors like ticks and other species of mosquitos and flies, which carry their own diseases like West Nile Fever, Lyme disease and tick-borne encephalitis. But unfortunately, it isn't just the bugs we need to be worried about. Climate change could also increase the occurrence of water-borne disease. In recent years, Europe has experienced the devastating impact of extended period of rain and floods, which wreak havoc on water treatment and distribution systems. Water can gather several pathogens from dumps, fields and pastures and flush them into water treatment and distribution systems. Kazmierczak also warns of pathogens carried in the sea: "As the arctic melts; salinity in seawater decreases, making it ideal for pathogens like vibrio. It's been seen more in the Baltic and North Seas. It is transferred from seafood or even exposure in an open wound if you're swimming in infectious water." Unearthing the zombie viruses Permafrost covers almost 15 percent of the northern hemisphere, a significant portion of which is concentrated in Siberia, Alaska and Greenland. As the name implies, permafrost is soil and rock that stays frozen for at least two consecutive years. It acts almost like a cold storage for history: mammoths, saber-toothed tigers and long extinct plants have been preserved, almost entirely intact. Some of what's stuck in frozen limbo isn't even dead – it's just dormant. Numerous 'zombie microbes' have been discovered in melting permafrost over the years, some after millennia. Researchers have raised fears that a new global medical emergency could be triggered – not by an illness new to science but by an ancient disease which modern human immunity is not equipped to deal with. The melting permafrost could also release old radioactive material and banned chemicals that had been dumped as waste. This was the case in 2016, when over 2000 reindeer were found dead in Siberia because of an anthrax outbreak. Melting permafrost thawed the carcass of a reindeer that had died decades ago and unleashed the dormant virus into the modern world. Dozens of people living nearby had to be hospitalized. This bizarre new threat may be another consequence of warming global temperatures, despite sounding like it's been pulled from the pages of a science fiction novel. But Kazmierczak says that the research is still in its nascent stages and permafrost exists in isolated regions with little habitation. Adapting to a new environment The changes in the geography of infectious disease, to a large extent, cannot be undone. Temperatures in Europe have already risen by over 2 degrees in the last decade alone, with no sign of it slowing down. But despite the warming climate, Kazmierczak is hopeful that Europe can adapt. 'National health infrastructures and awareness will be paramount in our adaptation. We already have examples from countries that have already dealt with these illnesses, and we can adapt them to Europe. 'We believe that a way to reduce our carbon footprint is also to bring nature into cities and homes – but hosting vectors, for example, is exactly the flipside that it can have. We need to make sure that we adapt with awareness.'
