Alaska GOP Pushes 800-Mile Gas Terminal and Pipeline That Could Decimate Climate

Republicans in Alaska want tax breaks for a Trump-backed megaproject that Indigenous activists oppose.

Republican Gov. Mike Dunleavy of Alaska has ordered state lawmakers to attend special legislative sessions over the summer and pass lucrative tax breaks for Alaska LNG, a proposed massive fossil gas export terminal on the Cook Inlet with an 800-mile pipeline across pristine wildlife preserves and much of the state.

With plans to export liquified “natural gas,” or LNG, to Asia, the fossil fuel megaproject is a top priority for President Donald Trump that Dunleavy is rushing to greenlight before his final term ends in December. Alaska LNG would accelerate the thawing of Arctic permafrost — potentially crossing a dangerous tipping point leading to a full-scale climate crisis — and threaten subsistence hunting and fishing grounds belonging to Arctic Indigenous communities.

For Iñupiat subsistence hunters who rely on animals such as moose and caribou to survive, disruptions to migratory routes from fossil fuel projects can be devastating. Rosemary Ahtuangaruak, former mayor of Nuiqsut and founder of Grandmothers Growing Goodness, said people in her tribal fishing village on the Colville River are also dealing with toxic industrial accidents and breathing problems from air pollution released by existing fossil fuel infrastructure on Alaska’s North Slope.

“This gas project can’t go through,” Ahtuangaruak told Truthout in an interview. “We should not be doing this just so some people can line their pockets today without thinking about tomorrow.”

With estimated costs currently up to $54.5 billion, some state lawmakers are also weighing whether Alaska LNG is bad economics. Trump, Dunleavy, and Glenfarne Group, the developer behind the project, are relying on lucrative state and federal subsidies to attract investors and political support. The climate activists at Friends of the Earth call the proposal “corrupt” and a “carbon bomb.”

Lois Parshley, a climate researcher at Public Citizen and co-author of a new report on the growing costs of the rush to export fracked gas as LNG, said the actual costs of building and operating Alaska LNG are likely much higher than the nearly $55 billion estimate provided by Glenfarne Group. The average cost overrun of operating LNG terminals in North America has been 59.7 percent, according to the report.

“The financial hazards in the LNG sector aren’t anomalies, they’re built into the business model,” Parshley said in email.

With the rise of renewable energy and future revenue dependent on global markets, building massive LNG export terminals is a big financial risk. Parshley said developers work with politicians behind the scenes to pass costs onto the government and consumers. For example, Alaska owns a 25 percent stake in Alaska LNG through a state-owned corporation, but its share would be diluted as more investors come on board and does not guarantee the state will receive 25 percent of future profits.


“We should not be doing this just so some people can line their pockets today without thinking about tomorrow.”

“The most comparable recent example is LNG Canada, which ran more than 130 percent over budget,” Parshley said. “Alaska’s proposed pipeline route traverses a longer distance, and more severe terrain, in a labor market that is structurally thinner.”

Billed as one of the largest energy projects in state history, Dunleavy and allied Republican lawmakers are currently haggling over tax breaks that Glenfarne Group says are necessary to make Alaska LNG viable for investors. Democrats, Independents, and even some Republicans say the megaproject risks leaving Alaskans on the hook for billions of dollars in hidden costs.

Larry Persily, a newspaper publisher and former federal coordinator of Alaska Natural Gas Transportation Projects, acknowledged the environmental concerns but said many voters are interested in promises of economic growth and access to cheap fuel in a state that shares oil revenues with residents — promises which Alaska LNG backers are loudly promoting.

“The environmental opposition to a proposed natural gas pipeline in Alaska is sincere, and they have some valid points, but it’s not resonating with the public very much because it’s not oil, it’s a very different product,” Persily said in an interview.

However, Persily said construction of an 800-mile pipeline across Alaska would be challenging on the accelerated timeline proposed by developers, and claims by officials that Alaska LNG could begin delivering cheap gas to residents by 2029 are unrealistic. Alaskan households could be exposed to high costs for gas if any utility “is irresponsible enough to sign a bad contract” before the project begins exporting gas overseas.

Even then, future global demand for LNG is uncertain. The shortages and high fuel prices associated with Trump’s tariffs and war on Iran won’t last forever.

“[Lawmakers] are in a tough political position in the state legislature, they really are,” Persily said. “I am one of those who thinks this is not going to happen, it’s not economic, but the sales job they are putting on is impressive.”

So far, lawmakers have been unable to pass tax breaks that both the Alaska House and Senate can agree on. Dunleavy ordered lawmakers to attend a second special legislative session that began on June 20 to hammer out a deal. Meanwhile, climate activists and some Indigenous people want to stop Alaska LNG altogether. In April 2025, a federal court rejected a lawsuit filed by the Center for Biological Diversity and other environmental groups against a federal export permit for Alaska LNG.

“The outlook for the project is so bad that the Trump administration is looking for foreign countries to pay for the project,” said Andrea Feniger, director of the Sierra Club’s Alaska Chapter, in a statement at the time.

Cooper Freeman, Alaska director for the Center for Biological Diversity and resident of Homer, said pro-industry politicians have pushed to build a pipeline connecting the state’s southern ports to gas fields on the North Slope for decades. With key lawmakers reluctant to approve huge tax breaks for Alaska LNG developers, Cooper criticized the legislature for wasting its time with fossil fuels as much of the world moves on.

“For lack of a better word, it’s a complete shitshow, and it’s unclear who is going to pay for it,” Freeman said in an interview. “If we had spent this time on transitioning to renewable energy and updating the grid here, we could be reducing our need for gas, which would be better for Alaskans and for wildlife and the places they live.”

Cooper said taxpayers across the United States should be aware of the Alaska LNG proposal and Trump’s broader push to rapidly scale up fossil fuel exports to the rest of the world. The U.S. is the world’s top producer of oil and gas, but utility bills are rising for households nationwide. Trump and Dunleavy are essentially asking Alaskans to take a 25 percent stake in a hydrocarbon megaproject that will send resources to other nations.

“I’m concerned that the only way this project can pencil out is with state tax cuts that put the costs of the project on the backs of Alaskan communities,” Freeman said. “It’s an extremely challenging construction environment, there’s a lot of environmental problems…and it’d be horrible for the climate.”

Trump has sought to rapidly expand fossil fuel production and exports in the frontiers of Alaska since his first day in office, when the president signed an executive order on “unleashing” the “extraordinary resource potential” in Alaska. The political push to open up pristine wilderness in the Alaskan Arctic to oil and gas drilling precedes the current administration.

Under President Joe Biden, federal regulators approved the Willow Project, a controversial oil drilling push by ConocoPhillips now underway near Ahtuangaruak’s village. As the former mayor of Nuiqsut, Ahtuangaruak became an outspoken opponent to the Willow Project, which inspired climate protests across the country.

“There’s lots of oil and gas development,” Ahtuangaruak said. “The Trump administration has allowed year-round drilling while previous administrations only allowed seasonal drilling, so the rapid development of these sites with increased risk of permafrost instability is only wreaking havoc.”

INTERVIEW

'We need more athletes to speak out': the future of sport in a warming world


Spanning venues in three countries, and welcoming a record number of teams, this year's World Cup will carry a massive carbon footprint – and see players exposed to potentially dangerous heat. Sports and sustainability expert Mael Besson tells RFI why organisers need to pay more attention to climate change, how it is already affecting professional and amateur athletes, and why we should expect bigger shifts to come.

Formerly in charge of sports and sustainability at France's Ministry of Sports and the World Wildlife Fund (WWF) France, Besson now advises French sports federations, insurance companies and local authorities through his agency Sport 1.5 – named for the Paris Agreement target to limit global warming to 1.5 degrees C.

RFI: What does sport have to do with the work of a conservation organisation like the WWF?

Mael Besson: Sport has a powerful influence on our lifestyles, habits, consumption and ideals.

The impact of an athlete drinking from a plastic bottle isn't limited to that one bottle. It's however many bottles are then consumed through imitation. And it's precisely because of this imitation effect that so many sponsors invest in sports: to promote and steer consumer behaviour towards their products.

RFI: The 2026 World Cup stands to be the most damaging yet in terms of climate change, but it's still world's biggest sporting celebration. What do you make of it?

MB: Societies throughout history have always needed moments to get people together. We need these moments of shared enthusiasm, be it cultural, religious, political. In this case, it's sport.

The problem lies in the format of this competition. It doesn't fit the trajectory for reducing greenhouse gas emissions to a level compatible with planetary limits.

The main issue is travel. A large proportion of the teams and fans who follow football are in Europe. This inevitably increases the number of people travelling, and travelling long distances, therefore by plane. Add to that a record number of teams, and this World Cup will be one of the most impactful.

RFI: Then there's the issue of marketing and consumption…

MB: Yes, and that's not usually factored into an event's carbon footprint. This ripple effect isn't taken into account. We'll count the number of bottles consumed at the event venue, but not the additional consumption by television viewers worldwide. We don't have the figures, and major sponsors are careful not to disclose the return on their investments. It would be complicated, anyway, because it's not just consumption at a specific moment; it's long-term brand capitalisation.

France adopted the Evin Law [in 1991] banning alcohol and tobacco advertising because it influences our behaviour and ultimately our health. Given our planet's limits, we need an Evin Law for the climate.

Future of Olympics in doubt as climate change drives up temperatures

RFI: The World Cup may also put athletes at risk, with at least a quarter of matches expected to be played in potentially dangerous temperatures. Norwegian player Morten Thorsby has called on Fifa to do more to protect footballers from extreme heat and take care of the planet. Does football need more voices like his?

MB: We need more athletes to speak out, including for the very survival of the sport. Increasingly, extreme weather events will prevent events from taking place or damage sports infrastructure. Even insurance is a problem. When it comes to making the adjustments we'll need in the future, sport risks being a lower priority than other sectors such as healthcare, hospitals and schools. Football therefore has every reason to be a leading advocate for the climate.

Athletes have the most legitimacy to demand that reducing greenhouse gas emissions be taken into account when organising tournaments. But every time they speak out on these issues, athletes are to some extent criticised and accused of hypocrisy because they are obliged to follow an international circuit and be surrounded by sponsors.

In France, a collective of more than 50 athletes, the Climate Sport Camp, is working on this issue. This involves making public statements in the media and lobbying ministers, federations and event organisers.

RFI: What do you tell the athletes you work with about taking responsibility?

MB: The first thing I tell them, if they don't want to speak publicly, is to stop promoting things they should avoid doing. A story on social media filmed on a plane – we know it will have an impact. But no one will ask you why you've stopped posting stories from planes. And by doing so, you've stopped promoting this mode of transportation. So the first step is to clean up your communications.

The second option for the athlete is to contact the governing bodies of their sport privately or via the athletes' commissions. Then athletes can specify in their sponsorship contract that they will not travel to the other side of the world to shoot an advert for sunglasses, for example. This cuts down travel.

There are plenty of concrete actions like that which don't necessarily leave athletes exposed.

RFI: This year's Tour de France starts on 4 July and lasts three weeks. It draws hundreds of thousands of spectators during the peak summer holiday season. Should organisers change the timing or is that impossible for economic reasons?

MB: That schedule may not be compatible indefinitely with climate change. It seems inevitable to me that it will change. July will become increasingly risky in terms of temperatures and even fires. Crossing mountains covered in woods could become more difficult.

It had to be postponed during the Covid pandemic. I don't know what the financial results were like that year, but I would think the Tour de France has enough going for it to withstand being pushed back.

However, adapting could also involve adjusting the schedule or even the regulations: introducing water breaks or safety measures when it gets too hot. Or perhaps modifying the route, with less demanding stages. It will likely be a combination of all these things.

RFI: Over the weekend of 24 May, two people in France died after taking part in amateur fitness events during an unprecedented heatwave. What can we learn from this?

MB: The main lesson is that you shouldn't just look at the temperature, but also its sudden increase. In a few days, it went from around 15C to 32C and people's bodies didn't have time to adapt. Over two weeks, even amateur athletes can adapt to intense heat. We're capable of exerting ourselves in 32 or 33C – but that doesn't mean it's not risky.

You also have to be careful when resuming activities after a break. We have to get used to helping our bodies adapt, whether to changing temperatures or to different intensities of training.

RFI: In a 2021 report for the WWF, you calculated the number of sports days lost due to global warming. What was your total?

MB: Based on IPCC projections, we estimated the number of days exceeding 32C, the threshold beyond which amateurs would be discouraged from doing sport. In a world warming by 2C, this would mean up to 24 extra days above 32C. But IPCC projections are generally underestimated, and it's likely to be more than 24 days.

The 2030-2050 projections of France's national climate change adaptation plan didn't predict any days would top 32C in May, but the recent heatwave has shown the contrary. These phenomena are arriving earlier than anticipated and with greater intensity.

What does 50C feel like? Touring ‘heat chamber’ allows French people to find out

RFI: What's the future of street sport? In 2050, will it still be possible to play football on dried-out public fields, or skateboard on hot asphalt?

MB: There are significant inequalities in adapting to climate change, in sports and elsewhere. The most disadvantaged populations will suffer the most from the consequences of climate disruption. They will have fewer resources to adapt. Unfortunately, sports facilities in disadvantaged neighbourhoods will likely not be the first to be protected.

Sport will continue to exist, but in my opinion, the timing will change. Summer may no longer be the peak season. In the Provence-Alpes-Côte d'Azur region in the south of France, already no mountain biking competitions take place in summer due to a high risk of fire. The same goes for climbing.

RFI: Is France's infrastructure adapted to climate change?

MB: No, clearly not. Our sports facilities are ageing – half were built before 1985. We've worked on energy efficiency, but often focusing on protection against the cold and very little on summer comfort.

Furthermore, specific facilities will be under pressure. Swimming pools and other cool areas are valuable resources for helping people withstand extreme heat. France's facilities are both ageing and inadequate, because they will have to accommodate more people. During the 2022 heatwave, we saw security guards at the entrance to pools because they were full and families couldn't get in. Making these facilities places of refuge will be a major challenge.

We could have more trees surrounding stadiums to act as natural cooling channels. There's also the issue of playing surfaces: synthetic pitches heat up much faster than natural grass. And we could consider staggering training times to allow for cooler periods.

RFI: How much of a threat is climate change to France's sports economy?

MB: I don't have an overall figure, but I have lots of examples of disciplines or clubs that are affected. In the Paris region, a kayak club had to cancel many of its courses and rentals due to flooding caused by storms. The Burgundy-Franche-Comté Sailing League told me that with the high temperatures, there are more cyanobacteria [potentially toxic microalgae], so swimming and other activities are banned.

On the coast, according to the WWF's figures, one in seven sports clubs in France will be threatened by rising sea levels at a temperature increase of 2C. In the mountains, the melting permafrost is making paths to iconic peaks impassable. Mountain guides find themselves having to reconsider their activities in August. Glacier trekking is difficult to postpone to September or winter.

Microbes frozen in ancient rubbish heaps help reconstruct ancient Greenlanders’ farms, seal hunts, and toilets



Microbiome of ancient middens sheds new light on the daily life of Paleo-Inuit and old Norse

Greenland has a long and checkered history of human settlement: several Paleo-Inuit cultures since approximately 2,500 BCE, descendants of Vikings between the tenth and fifteenth centuries, and early modern Danes since 1721. All left their traces on the landscape, for example in the form of ancient domestic rubbish heaps. Composed of waste like animal bones, excrement, mollusk shells, and human artefacts, these middens are a precious resource for archaeologists.

But what can microbiologists contribute to the study of these middens, for example revealing which diseases plagued historic populations, and which animals they kept but perhaps didn’t eat? And now that the Arctic is warming three to four times faster than the global average, could thawing middens be a source of resurgent infectious diseases?

“Here we show that the risk of release of ancient pathogens from ancient middens on Greenland is currently low,” said Dr Frank Møller Aarestrup, a professor at the National Food Institute of Denmark Technical University and corresponding author of the article in Frontiers in Microbiology. “Rather, we found that these middens in the cold Arctic acted like long-term natural experiments. Human- and animal-associated bacterial signals, including opportunistic bacteria and bacteria carrying antibiotic resistance genes, have remained detectable in them many centuries later as the legacy of human activity: for example, livestock farming by the ancient Norse.”

Studying the dustbins of history

In 2020 and 2021 in West and South Greenland, Aarestrup and colleagues collected samples from several middens frozen in time by permafrost and covering 4,500 years of human life in Greenland. These had been identified by the Greenland National Museum and Archives registry. At ancient Norse sites, for example at Kapisilit and Narsarsuaq, they also collected soil samples from historic winter enclosures and summer grazing grounds for livestock. The researchers used DNA sequencing to reconstruct entire bacterial communities. They compared their findings to those in 143 soil samples from areas of permafrost distant from any historical settlements.

The sequencing revealed between 9 and 202 bacterial species per midden, for a total of 1,207 species. Importantly, many of these species were previously undescribed and could only be assigned to broad taxonomic categories like families and orders. “This […] highlights how poorly described Arctic soils and archaeological deposits remain,” wrote the authors.

Middens had significantly richer bacterial communities than surrounding pristine soils, confirming that they preserved the biological legacy of human activity. Middens from the Paleo-Inuit had the most soil-like bacterial communities, indicating that the microbial imprint from humans and animals diminishes over time.

Groups of bacteria known to live on or within animal and human hosts predominated in most middens. These included harmless bacteria from human feces like Clostridium massilliamazoniense, Clostridium baratii which can cause botulism, and Paeniclostridium sordellii, which can cause life-threatening human diseases like toxic shock syndrome, sepsis, and gas gangrene.

Bacterial communities depended strongly on the type of waste material in each midden. For example, those from early colonial era Nuuk contained decomposing seal skins and were rich in the bacterium Clostridium perfringens, a major cause of food poisoning. Romboutsia species and Paraclostridium sordellii – which live in the gut of many animals – were abundant in middens filled with animal carcasses, while early Norse middens with decomposing bones were rich in unknown species of Proteobacteria and Clostridiaceae.

No reason to worry

The authors also found a great diversity of genes associated with antimicrobial resistance in bacterial genomes from middens. The presence of the same genes in ancient and contemporary soil layers signaled that microbes resistant to antimicrobials can linger in permafrost for centuries. However, the authors concluded from the spatial distribution of these pathogens that they don’t spread far from thawing middens. They thus appear to pose little risk to public health – at least for now.

"The microbiome in thawing permafrost appeared to be rapidly replaced by local contemporary environmental microbes once released into run-offs,” observed co-author Dr Saria Otani, an associate professor at the National Food Institute.

“However, it is not known whether the risk of release of pathogens will increase with increasing temperatures, or whether this might be greater in other Arctic regions. For this reason, it would be prudent to include microbiome characterization as a routine monitoring aspect during archaeological visits," counseled last author Dr Anders Priemé, a professor at the University of Copenhagen.

Over a billion children exposed to three or more climate hazards UN report shows

More than one billion children face at least three overlapping climate hazards, the UN childrens' agency Unicef has warned, while highlighting the disproportionate impact in some regions of the world.


Issued on: 16/06/2026 - RFI

For the report, the UN agency cross-referenced data showing where the roughly 2.4 billion children on the planet live with the geographic distribution of the eight most common climate impacts. They are coastal flooding, river flooding, drought, tropical storms, heat waves – at least three days above a high temperature threshold, which varies by country – extreme heat, wildfires and sandstorms.

The report primarily focuses on the 1.1 billion children who are exposed to at least three risks, with the most common combination being drought, extreme heat (above 35 degrees Celsius) and heat waves.

That combination affects some 296 million children, including 74 million in Nigeria, 34 million in Pakistan and 32 million in India.

The number of children in this three-or-more category has increased sharply over the past 20 years.

Children are 'first victims' of climate change, French rights watchdog warns

Almost all children – some 2.3 billion – are exposed to at least one risk. Two billion are exposed to at least two, while 364 million face at least four.

Of the 123,000 children exposed to seven or more climate hazards, some 46,000 are in Myanmar.

"Children are at the forefront of the impact of climate change," said Unicef chief Catherine Russell.

As for the worst place for a child, "there isn't a super short answer," one of the report authors, Tom Slaymaker, told AFP.

"But they're not all equal," Slaymaker said. "We do see some hot spots... it's really concentrated in Sub-Saharan Africa and parts of South Asia."
Chad's children at risk

Countries with large populations of children – including Bangladesh, India, Nigeria and Pakistan – are at the top of the list for the number of children exposed to at least three hazards.

But in sheer percentage terms, countries in Sub-Saharan Africa – particularly the Sahel – have the largest proportion of children affected by hazards. The impacts are often exacerbated by governments' inability to cope with climate hazards.

Chad, for example, faces a humanitarian crisis with limited access to water, electricity and food. According to the report, more than 95 percent of kids in the country are exposed to at least three hazards – one of the highest proportions in the world.

'A vicious cycle that exhausts bodies and minds': the human cost of climate change

Other particularly vulnerable countries include 39 island states that face challenges such as limited freshwater, import dependence, and inability to easily shelter elsewhere after a disaster such as a hurricane.

No country is truly spared, the report shows.

"In many countries, there will be small pockets of the population which are not exposed to these hazards," Slaymaker said. "They tend to be in the northern hemisphere, particularly so, parts of Scandinavia."

But that is because the report looks only at the eight most common risks worldwide, he stressed, noting that children in those countries may face other threats not covered in the report, such as melting glaciers or thawing permafrost.

World will cross 1.5°C warming limit by 2030 if emissions continue at current rate - report

Published on

The rate of human-induced warming remains at an all-time high, according to the latest Indicators of Global Climate Change report.

The world is edging dangerously close to the Paris Agreement’s 1.5°C warming threshold, with human-induced warming reaching 1.37°C in 2025, a major new report warns.

If emissions continue at current levels, the 1.5°C limit will be crossed around 2030, according to the analysis by more than 70 scientists from 56 institutions across 17 countries.

The fourth edition of the Indicators of Global Climate Change (IGCC), published today (11 June) in the journal Earth System Science Data, tracks the key measurements that tell us how fast the climate is changing and why. It paints a clear picture: the Earth is warming at an accelerating rate, driven almost entirely by human activity.

“Our study shows greenhouse gas emissions are at an all-time high, mainly from the burning of fossil fuels,” says Dr. William Lamb, Senior Researcher at the Potsdam Institute for Climate Impact Research (PIK), Germany.

“The good news is that solutions are already available. By investing in renewables and electrification, governments can cut emissions while building cleaner, more reliable and more secure energy systems.”

World’s carbon budget will be exhausted in three years

The carbon budget – the total amount of CO2 that can still be emitted while keeping warming less than 1.5°C above pre-industrial levels – now stands at just 130 billion tonnes from the start of 2026. At current emissions levels, that will be exhausted in around three years.

The 1.5-degree limit is the cornerstone of the 2015 Paris Agreement, an international treaty designed to prevent the most catastrophic impacts of the climate crisis.

Global greenhouse gas emissions hit a record 56.8 billion tonnes of CO2 equivalent in 2024, driven mainly by the burning of fossil fuels. Concentrations of the three major greenhouse gases – carbon dioxide, methane and nitrous oxide – have all risen since 2019, with CO2 now at 425.6 parts per million.

The report also found that the Earth’s energy imbalance – the gap between the heat entering the planet and the heat escaping it – has more than doubled in recent decades and is now at a record high. This means the planet is storing heat faster than at any point in modern measurements.

“The Earth’s energy imbalance is growing fast, driving changes in every component of the climate system, including ocean and continental warming, permafrost thawing, ice loss, and sea level rise,” says Dr Karina Von Schuckmann from French research institute Mercator Ocean International.

Sea are rising and getting warmer

Global sea levels reached a new record in 2025 – 23cm of rise since 1901 – and the rate is accelerating. The oceans are absorbing much of the excess heat, with average sea surface temperatures hitting their second highest level on record last year.

A newly added indicator in this year’s report captures the scale of marine heatwaves: the number of days affected has more than tripled globally between 1991 and 2025. In 2025 alone, the world experienced 65 marine heatwave days, damaging ecosystems, threatening fish stocks and disrupting the ocean-atmosphere systems that regulate the Earth’s climate.

On land, the picture is just as bleak. Average maximum land temperatures over the last decade were nearly half a degree higher than the decade before – a shift that is pushing extreme heat to new levels around the globe.

“Nearly all of the warming over the last decade is driven by human activities,” says Dr Samantha Burgess of the Copernicus Climate Change Service. “The impacts on livelihoods and ecosystems are already being felt worldwide, and will accelerate as temperatures continue to increase.”

The scientists behind the report are also sounding the alarm about a less visible risk: the global datasets used to track these changes are themselves under threat. Funding cuts – including the Trump administration’s decision to scrap the US State Department’s global air quality monitoring programme last year – are creating dangerous gaps in the evidence base that climate science and policy depend on.

“Without this, future assessments will be much more difficult at a time when urgent climate action is needed,” warns Dr Chris Smith of the International Institute for Applied Systems Analysis.

Extreme heat is reaching Europe’s most northern cities. These mayors are determined to solve it

From Athens to Oulu, European mayors are among 50 worldwide teaming up to protect citizens against extreme heat.

Last July, Antalya on the Turkish Riviera broke records when temperatures crept above a scorching 46°C. Home to more than 2.6 million people – and millions more tourists each summer – the Mediterranean city was long accustomed to heat.

But something had shifted.

“In recent years the heat has changed in character: heatwaves that are longer, more intense and more frequent, straining our residents, our outdoor workers, our health services and the millions of visitors we host each year,” says Melike Kireçcibaşı, Head of Antalya’s Climate Change and Zero Waste Department.

Antalya is not alone. Extreme heat is now the deadliest climate hazard on Earth, killing nearly half a million people every year.

Europe’s May heatwave – which saw temperatures in France run 10 to 15 degrees above normal, breaking all-time spring records and causing deaths across the continent – was described by UN climate chief Simon Stiell as a “brutal reminder of the spiralling impacts of the climate crisis”.

With the World Meteorological Organization (WMO) warning that a potentially powerful El Niño is now developing, set to amplify already-rising temperatures across Europe and beyond this summer, the pressure on cities to act has never been greater.

Now, on World Environment Day (5 June), more than 50 mayors – from Athens to Oulu to Yangzhou – are joining forces. The United Nations Environment Programme’s new ‘50@50’ initiative brings cities together to share tested solutions, stress-test their systems against future heat scenarios, and accelerate action before the next heatwave strikes.

Extreme heat is already reshaping daily life in cities around the world,” says Inger Andersen, UNEP’s Executive Director. “50@50 helps local leaders move faster by sharing practical solutions that protect people, reduce inequality and strengthen urban resilience.”

Mapping heat exposure for targeted action

Prompted by rising temperatures, Antalya embarked on the EU-supported CLIMAAX-MUHIR project – a province-wide heat-risk assessment modelling current and future dangers.

“The findings were sobering,” Kireçcibaşı tells Euronews Earth. “Our climate projections show heatwave occurrence rising sharply under a high-emissions scenario; some districts could see several-fold increases in heatwave frequency by mid-to-late century.”

The project also mapped where vulnerable populations and extreme heat intersect – and the results were stark. Although built-up areas make up just 2.56 per cent of Antalya’s territory, they house around 56 per cent of its population, and the city’s highest-risk heat zones overlap almost precisely with where people actually live. “That tells us where to act first,” says Kireçcibaşı.

Guided by these findings, Antalya developed a Heat Action Plan directing cooling infrastructure, shade, green spaces, early-warning systems and health support to the neighbourhoods that need them most.

Redeveloping the most vulnerable neighbourhoods

A similar approach is underway in Athens – another 50@50 participant – where an Urban Heat Atlas identifies where heat exposure and social vulnerability overlap. The initiative is driving the redevelopment of Elaionas, one of the city’s most thermally vulnerable districts, where a new 215,000-square-metre metropolitan park is being created.

Athens has committed to planting 5,000 trees every year; since 2024, more than 12,400 have already gone into the ground. Progress can be tracked in real time through the Athens Trees digital platform, designed to build public trust and citizen engagement.

“Combined with school gardens, microforests, neighbourhood parks and cooling elements in public spaces, these interventions are helping us create a cooler and healthier urban environment,” says Elissaios Sarmas, CEO of Develop Athens.

Both cities hope their hotspot-mapping techniques will be among the most transferable contributions to the 50@50 network.

That sharing of knowledge is the initiative’s core purpose. Building on its own 50°C simulation exercise – in which the city stress-tested its systems against temperatures it has not yet experienced but scientists say it will – Paris is now helping to extend that model across the network.

“Extreme heat is becoming a defining challenge for cities worldwide,” says Emmanuel Grégoire, Mayor of Paris. “Cities must act together to anticipate extreme heat and protect their residents. Cooperation is our most powerful tool.”

Over the next year, a dozen cities will conduct their own extreme heat stress tests with support from UNEP, the C40 Cities Climate Leadership Group and the City of Paris.

Heat is hitting from the Mediterranean to the Arctic Circle

Perhaps the most striking signal of how far the extreme heat problem has travelled comes from a city near the top of the world. Oulu, the EU’s northernmost large city in Finland, sits close to the Arctic Circle – and yet it too has joined 50@50.

Last year, Finland endured three consecutive weeks of 30°C temperatures in a “truly unprecedented” heatwave. An ice rink in the north of the country opened up to those seeking refuge from the heat, while local hospitals were inundated. The heatwave also sparked concerns over the welfare of reindeer, who risked overheating.

“The urban heat islands are starting to form and make urban spaces uncomfortable,” says City Architect Sanna Pääkkönen. The challenge is compounded by the fact that the Finnish city was built for an entirely different climate.

“Most of our apartments, schools, daycare centres and working environments are built with cold winters in mind – and now they are getting too hot in summer,” Pääkkönen explains.

Beyond heat, Oulu’s Climate Roadmap must also contend with more frequent flooding, storms, and the disruption that shifting freeze-thaw cycles bring to buildings and infrastructure designed for reliable permafrost.

City planners are now factoring sunlight, heat and shading into new urban developments – and investing in cycling and pedestrian infrastructure to cut the car emissions that drive the temperatures they are scrambling to adapt to.

The thread connecting Antalya’s heat maps, Athens’ new parks and Oulu’s rewritten planning rules is the same: cities can no longer design for the climate they have. They must design for the one that is coming.

That a city near the Arctic Circle is now planning for summer heat it was never built to handle demonstrates how rapidly the problem is moving. Keeping pace with it, 50@50’s organisers argue, requires cities to stop trying to solve it alone.

Spring storms are becoming increasingly common in Europe

Storm Dave, which swept across northern Europe over the Easter weekend, is a recent example of what new research from the University of Gothenburg has revealed. Spring storms forming over the North Atlantic have become more common than they were 80 years ago, and this is due to climate change.

In the northern hemisphere, storm seasons follow a seasonal cycle. Storms are weakest and least frequent in summer, and most intense in winter. As a result of global warming, storm patterns and their course have changed, and several studies have indicated that winter storms appear to be occurring more frequently and with even greater intensity.

Less Arctic sea ice

“One factor that may be contributing to the formation of more storms is the reduction in Arctic sea ice. Open water can release more heat and moisture into the atmosphere than when there is a layer of ice covering the sea. The shrinking sea ice also means that storms can take new paths across the Arctic oceans,” says Zhi-Bo Li, researcher in climatology at the University of Gothenburg.

Most climate research focus on how climate change has affected the peak and off-peak seasons for storms, in winter and summer. However, in a new study, Zhi-Bo Li and his colleagues have chosen to investigate how storms in the Northern Hemisphere have changed during spring and autumn from the 1940s to the present day.

Changes in spring and autumn

“We can see that storms over the North Atlantic, the North Pacific and the Arctic Ocean have changed very noticeably during spring and autumn. A storm as powerful and persistent as Dave used to be quite rare in April, but now we are seeing them occur more frequently and pass through longer distances. Previously, many spring storms would fizzle out over the British Isles, but now they sometimes reach as far as Scandinavia,” says Zhi-Bo Li.

The researchers have used historical weather data from 1940 to 2024 to build up a picture of how storms have changed. The main finding of the study is that these changes vary depending on the season and region. In the Arctic, north of the 65th parallel, spring storms are becoming more powerful, lasting longer and travelling further. In the North Atlantic, more spring storms are forming than before, whilst in the North Pacific, it is the autumn storms that have intensified and are lasting longer.

Study fills a gap

“Generally speaking, we are seeing a clear change in the storm landscape in the Northern Hemisphere. Our study fills a gap in our understanding of how storms behave during the transition from winter to summer; these are significant changes that have previously been overlooked. This is crucial if we are to develop better weather forecasts and plan effective adaptations to a changing climate.”
