Heat waves in Europe are becoming more dangerous. Here’s what this means for travelers

Growing up in Texas, Mary Beth Walsh thought she was used to high temperatures. Her hometown of Dallas, which is currently plagued by incessant heat, regularly suffers from heat waves.

But when the 21-year-old visited Athens with her friends in mid-June, she was shocked by the “unbearable” 98 Fahrenheit (37 Celsius) heat she faced. “I actually had no idea how much heat was there until we got there, which was quite surprising,” she told CNN.

“I always joke about how I have such a high heat tolerance; I take my sweatshirt to class in August (in the US),” she said.

But the apartment she was staying in had no air conditioning, and the daytime temperatures were too high to explore the city on foot. “Our energy levels were lower than we thought,” she said. “It felt quite unbearable walking in the direct heat.”

Climate crisis-induced, sweltering summers in Europe are now a reality that many tourists are waking up to. Interest in visiting the warmer Mediterranean countries fell in 2023 due to record heatwaves and forest fires, with more temperate destinations becoming increasingly popular, experts say.

Recent heat-related deaths and disappearances in Greece, including that of British TV personality Michael Mosley, could further fuel this shift north as extreme heat influences holiday choices.

The extent to which both the travel industry and tourists can adapt to the rising tide of climate impacts is becoming an increasing challenge for countries in southern Europe, many of which rely on tourism to boost their economies.

Night shift

Recent high temperatures have brought the climate crisis into sharp focus for some European holidaymakers.

“The climate crisis that we fear will happen in 10 or 15 years’ time is already here in some parts of the world. That’s the scary part,” said Roo Clark, 28, from Suffolk in eastern England, who is currently at his girlfriend is staying on the Greek island of Skyros, told CNN.

“Five years ago, me and my friends wouldn’t even have talked about it (climate change), whereas now it’s more of a conversation.”

Authorities in Greece have repeatedly warned tourists not to underestimate the intense heat, especially in the middle of the day. Walking in high temperatures is a common thread linking the recent deaths in the country.

According to CNN meteorologists, temperatures in Greece in the coming weeks are expected to be between 90 and 95 degrees Fahrenheit (low to mid 30s Celsius), a few degrees above the summer average, with the exception of one to two days when it rains. is forecast, which will keep temperatures low.

Stefanos Sidiropoulos, who runs Greece’s largest travel agency specializing in outdoor activities, said tourists should not jump into activities right away. “People who come from Northern Europe, or from Canada, places with colder temperatures, have a harder time. They need time to adapt to these conditions,” he told CNN.

Sidiropoulos’ travel agency, Trekking Hellas, now offers a number of activities when temperatures are lower, such as during sunrise and sunset. “Or at night, with torches,” he adds.

Addicted to tourism

The impact of climate change on where tourists spend their holidays will have serious consequences for some countries that rely on income from travellers.

In Greece, tourism contributes nearly 38 billion euros ($41 billion) — about 20% of the country’s entire economy, according to the World Travel and Tourism Council.

In Italy, where heat warning level 3 (the highest warning) has recently been issued for the cities of Rome, Perugia and Palermo, tourism represents 10% of the country’s economy, according to the latest figures. One in eight jobs is related to this sector.

According to the European Travel Commission (ETC), a non-profit organization responsible for promoting Europe as a travel destination, concerns about climate change among European travelers increased by 7% following the summer 2023 heat wave, which left thousands of people stranded. fled the forest fires on the Greek island of Rhodes.

This followed a decline in interest in holiday destinations in the southern Mediterranean between the summers of 2022 and 2023, with cooler destinations such as the Czech Republic, Bulgaria and Denmark becoming increasingly attractive, ETC told CNN.

“Travelers are increasingly aware of extreme weather events and their potential impact on their vacations,” Eduardo Santander, CEO of ETC, told CNN. He added that in the future this could lead to more travelers visiting southern Europe in spring and late autumn rather than during summer. the warmer summer months.

For now, Santander says tourists’ concerns about climate change are typically relatively short-lived. “Travelers worry after the summer, but often forget about these events when they book their next vacation in the spring,” he said.

‘Riddled with bites’

Extreme heat is a consequence of climate change that is affecting tourist attractions across Europe. But there are more.

According to the European Center for Disease Prevention and Control (ECDC), warmer conditions due to climate change are pushing populations of disease-carrying mosquitoes into new areas in Europe.

Clark, the tourist currently staying on Skyros, said that the number of mosquitoes was very high during the heat wave in early June.

“We were absolutely covered in bites. There was no wind and even though we sprayed ourselves, they still found a way,” Clark told CNN. “It was definitely the low winds and the high temperatures that did it.”

One important mosquito species that can spread dengue, chikungunya and Zika viruses is called Aedes albopictusis now established in many European countries, including Greece, Italy, Portugal and Spain, according to the ECDC.

ECDC director Andrea Ammon said travel could help expand the species’ range. “Increased international travel from countries where dengue is endemic will also increase the risk of imported cases,” she said in a statement.

Last year, the ECDC recorded 130 locally acquired cases of dengue in Europe, compared to 71 cases in 2022.

ECDC told CNN that no cases of locally acquired dengue have been reported in Europe so far this summer, but based on previous trends over the summer, they expect the first cases to be reported in the coming weeks.

One human case of West Nile virus infection spread by indigenous people Culex pipiens According to the ECDC, a mosquito was reported in the Spanish province of Seville in March. Last year, the organization recorded 713 locally acquired human cases of West Nile virus infection in nine EU countries, resulting in 67 deaths.

Adapting to the ‘new normal’

Last summer’s record temperatures around the world were caused by a combination of human-induced climate change and the return of the natural phenomenon El Niño, which is causing higher global temperatures.

This combination raised temperatures to record levels in parts of Europe, the fastest warming continent in the world.

But even if the impact of El Niño subsides, experts say the long-term trend of global warming will continue. “Climate change is making more extreme events more common and subsequently more severe,” Rebecca Carter, director of climate adaptation and resilience at the World Resources Institute, told CNN.

She added that high tourist numbers in some regions of Europe are putting a strain on already stretched local authorities as they combine the need to protect residents from the heat and protect visitors.

Carter said the travel industry needs to consider climate adaptation. “I don’t think the travel industry is thinking about it as much as it should,” she said, adding that booking rules could be made more flexible for things like flights and hotels.

“When people plan such trips, they do it weeks or months in advance and you can’t predict when a specific place will experience extreme heat.”

Some tourists, such as parents whose children are in school, have less flexibility in deciding travel plans, Carter said. In these circumstances, she said planning was crucial: “What would you do if there was an extreme heatwave and the power went out? Can you map out in advance where you could go for help?”

Sidiropoulos of Trekking Hellas agreed that planning ahead is important, but he also wanted visitors to get out and enjoy the beauty of Greek culture and nature.

“I always tell people who travel, ‘Don’t stay in your hotel and just do the classic things, like going to a restaurant,’” he said. “You have the opportunity to see nature… and to see the authentic side of our country.”
