The World Health Organization (WHO) has unveiled new guidance for governments seeking to protect people from extreme heat, a growing priority as climate change pushes temperatures higher worldwide and intensifies heatwaves and related health risks.
The launch came as the US National Oceanic and Atmospheric Administration said on Thursday that El Niño has developed in the tropical Pacific. The climate phenomenon – which occurs naturally every few years – is predicted to intensify to a moderate or strong level this autumn, the service said.
Scientists have warned that a strong El Niño weather pattern could fuel “unprecedented” weather extremes in the coming months, including severe fires and droughts, and may make 2027 the next record-breaking hot year as it supercharges human-driven warming.

Unveiling updated recommendations for “Heat-Health Action Plans”, which are tailored for Europe but can be adapted globally, Hans Henri P. Kluge, WHO’s regional director for Europe, said that over the past four years, heat has claimed more than 200,000 lives across 32 European countries.
He added that most of those deaths were “entirely preventable” and are “just the tip of the iceberg”, with millions more people being affected physically and mentally by the effects of extreme heat. Scientists have said Europe is the fastest-warming continent.
“Individual action, such as keeping out of the heat, keeping our homes cool and keeping our bodies hydrated, can make a big difference in protecting us, but it is not enough to fight a systemic crisis,” Kluge said in a statement. “We need a coordinated, powerful and institutional response.”
The new guidance focuses on the importance of providing early warning and alerts, targeting vulnerable groups and putting in place longer-term prevention measures across households and buildings, especially in cities which are often hotter than rural areas, as well as offering practical advice on how to do that.
Who’s most vulnerable to heat?
Heat can trigger exhaustion and heat stroke, and exacerbate existing medical conditions, including diabetes and cardiovascular, respiratory and cerebrovascular diseases, as well as disrupting sleep and aggravating mental health conditions.
In a fact-sheet, the WHO warned that rising global temperatures, more people living in cities and demographic aging are increasing exposure to heat and vulnerability to its impacts. Some of the most at-risk groups include older people, children, outdoor workers, athletes and sports players, those attending mass public gatherings and poorer social groups, it said.
Employers need plans to protect workers from rising heat stress, UN says
The WHO emphasised, however, that it does not just propose wider use of air-conditioning (AC) as the solution because it is not sustainable, is often unaffordable for those with low incomes and increases energy demand.
“It contributes to both the urban heat island effect and climate change, thus worsening heat exposures in the medium and long term,” the fact-sheet said.
Europe’s intense May heatwave
On Wednesday, Europe’s Copernicus Climate Change Service (C3S) announced that May 2026 was the second warmest May on record globally across land and sea.
Across Europe, the month saw a rapid transition from much cooler-than-average conditions to one of the most intense heatwaves ever observed this early in the year in western Europe, C3S said. Numerous temperature records were broken for May with France, the UK, Ireland and Portugal enduring particularly severe conditions, it added.
C3S noted that the quick flip to a period of extreme heat “likely increased impacts on populations, leaving little time for people – or crops and ecosystems during growing season – to acclimatise to much higher temperatures”.
“Prepare for rougher times”
In a foreword to the new WHO heat plan guidance, Wopke Hoekstra, European Commissioner for Climate, Net Zero and Clean Growth, wrote that extreme heat is responsible for some 95% of all climate-related deaths in Europe, undermines labour productivity and risks overwhelming hospitals.
He noted that investing in emission reductions is far cheaper than paying for climate damage.
“Yet, while we push for emission reductions, we must also prepare for rougher times. Strengthening Europe’s climate resilience, protecting both well-being and economies, is non-negotiable,” he added.
By the end of this year, the European Union plans to adopt a new framework for climate resilience across all sectors, including health.
In the UK, the independent Climate Change Committee warned last month that, in a projected scenario of 2C of global warming by 2050, recent record hot summers will become the “new normal” in the usually temperate country, putting regular stress on domestic agricultural production.
Heatwaves lasting at least a week will be common and could regularly exceed 40C in the south, the committee’s report on adaptation said, posing challenges for keeping vulnerable people sufficiently cool.
It recommended that cooling will be needed in hospitals, prisons, schools and care homes, while regulation should set maximum temperature limits for workplaces.
Berlin’s Heat-Health Action Plan
On Thursday, the WHO said that since the publication of the first edition of its heat and health guidance in 2008, far more scientific evidence and practical experience have been gained. Many countries have since established Heat-Health Action Plans, but their adoption and implementation have been uneven, it said.
Comment: Early warnings for heatwaves can save lives – and we need them now
In Germany, where local authorities are primarily responsible for heat protection, the Berlin Senate adopted a state-wide heat–health action plan in 2025. It contains 72 measures to improve heat protection for residents, including informing them every summer of the risks via traditional and digital media.
A heat protection portal offers access to Berlin’s heat–health action plan, and a map of cool places in the city, as well as behavioural advice.
Berlin Senator Ina Czyborra said the city is also working on the long-term maintenance and expansion of parks, green spaces and water bodies, which can all help alleviate the effects of heat.
“One thing is clear: protection from heat is a cross-cutting task that can only be tackled through a joint effort by all administrative departments and levels, and with the involvement of civil society actors,” she added in a statement.

Analysis: UK newspapers have already printed 63 editorials in 2026 backing North Sea drilling
UK newspapers have already published 63 editorials this year calling for more oil and gas extraction in the North Sea, according to Carbon Brief analysis.
The national outlets, including the Sun, the Daily Telegraph and the Times, argue that the nation “needs” more North Sea drilling to provide “home-sourced oil and gas” amid a “full-blown energy crisis”.
These newspapers seek to blame energy secretary Ed Miliband’s “net-zero crusade” for curbing UK fossil-fuel production – despite supplies dwindling for decades before he took the role.
The push for North Sea drilling in newspaper editorials – considered a publication’s formal “voice” – is part of a wider rejection of net-zero policies by the UK’s right-leaning press.
Figures ranging from ex-Labour prime minister Tony Blair to hard-right Reform UK leader Nigel Farage have repeated similar arguments that more drilling will “boost” the UK economy.
Even US president Donald Trump has weighed in, attributing, in part, the resignation of Keir Starmer as UK prime minister to him “fail[ing] badly” on North Sea oil.
Despite these claims, experts say trying to extract the last barrels of domestic oil and gas would have no impact on people’s energy bills and very little effect on energy security.
More drilling
North Sea oil and gas production is a highly politically charged issue in the UK, especially under the current Labour government.
When Labour won the general election in 2024, the new government committed to a “phased and responsible” transition away from fossil-fuel extraction in the North Sea.
As part of this pledge, it ruled out issuing new exploration licences for oil and gas. Since then, the government has allowed some “tiebacks”, where new drilling is undertaken close to existing sites.
Roughly 90% of the fossil fuels that are likely to be extracted in the North Sea have already been burned. North Sea oil and gas extraction was, therefore, already on a clear downward trajectory long before Labour came to power, having dropped 75% between 2000 and 2024.
Nevertheless, many newspapers have relentlessly called for more oil and gas production, framing the Labour policy as “self-destructive” and compromised by “green ideology”.
This has ramped up significantly in 2026. Just six months into the year, newspapers have already published 63 pro-North Sea editorials, according to analysis by Carbon Brief. This is more than double the number published in 2025, as shown in the figure below.
Right-leaning newspapers have led this campaign, with the Sun alone publishing 25 editorials, while the Daily Telegraph and the Times have published 10 each.
‘Full-blown energy crisis’
The biggest surge in pro-North Sea drilling editorials came in March, as the Iran war escalated and a global energy crisis began to take shape. Newspapers published 24 such editorials that month, despite the crisis largely arising from the world’s reliance on fossil fuels.
The Daily Express said the UK needed more “home-sourced oil and gas” and the Daily Mail highlighted the “perverse limit on domestic fossil-fuel production”.
As the weeks progressed, the Sun lamented price rises and potential fuel shortages, proposing North Sea drilling as a solution to the “full-blown energy crisis”.
Yet, UK oil and gas is sold by private companies on the open market at international rates. This means UK consumers have no particular right to the fuels or control over the prices they are bought for.
The Sun claimed – without evidence – that if the North Sea had been prioritised, the UK “might just have the cheapest electricity in the world”. It also said net-zero “forces us to spend billions” on imports.
In fact, the UK’s high energy prices are primarily the result of its reliance on gas to generate electricity.
The nation is reliant on oil and gas imports, in part, because the North Sea is a “mature basin” that saw its output collapse long before the UK even had a net-zero target.
Renewables and low-carbon technologies – often dismissed by the same newspapers – are expected to have a far greater impact on cutting imports than new drilling ever could.
Miliband’s ‘crusade’
Much of the criticism by these newspapers of Labour’s North Sea stance is tied to their highly personal criticism of Miliband. Of the 63 editorials arguing for more drilling, nearly three-quarters also attacked him as a “net-zero zealot” on a “green crusade”.
The Times said the energy and net-zero secretary was pursuing a “masochistic policy” by not expanding North Sea drilling and that he had “cloaked his zealotry in spurious rationality”.
This all fits with a broader trend that has seen right-leaning newspapers launch frequent, personal attacks on Miliband.
In the roughly two years since Labour won the election, giving the government a clear mandate for its net-zero policies, there have been around 230 editorials criticising Miliband.
(These have redoubled in recent days, amid rumours that he may be made chancellor under Andy Burnham, if the new Makerfield MP becomes the next prime minister, as is widely expected.)
Such attacks have increasingly spilled over into politics. Conservative shadow energy secretary Claire Coutinho has accused Miliband of “fanaticism” and Conservative leader Kemi Badenoch has even likened him to a “Nigerian military dictator”.
The newspapers have also interpreted any support for North Sea drilling as a rebuke of Miliband. Both the Sun and the Daily Telegraph welcomed an essay by Blair, in which he argued that “we must…use what is left of our North Sea oil and gas resources”.
The Sun heralded Blair as Labour’s “most successful election winner” and said he “nailed the chief mistakes” of the current government, including:
“Allowing Ed Miliband free rein on net-zero – especially the banning of North Sea drilling.”
Several of the newspapers have also thrown their support behind the Conservative party, as it frames itself as an anti-net-zero, pro-fossil fuel alternative to Labour.
The Daily Mail described Badenoch’s proposal to drill more in the North Sea as a “concrete plan”, while the Sun – in an echo of Trump’s slogan – has simply urged her to “drill, Kemi, drill”.

Key developments
Heatwave scorches European agriculture
‘PUSHED TO THEIR LIMITS’: The record-breaking heatwave that swept through much of western and central Europe in recent weeks had myriad impacts across the continent, reported Carbon Brief. Martin Lines, chief executive of the Nature Friendly Farming Network, explained: “Prolonged high temperatures place huge stress on livestock, dry out soils and reduce crop resilience, all while putting more pressure on nature.” The Times noted that “refrigerated warehouses were pushed to their limits” by the high temperatures.
POULTRY PROBLEMS: “At least several hundred thousand poultry” perished in France due to the extreme temperatures, the head of a French poultry-industry group told Reuters. A separate Reuters article said that “cows and pigs were suffering from heat stress” in Belgium, “which has raised concerns about milk and meat production”. Meanwhile, UK government data obtained by Carbon Brief showed that “twice as many animals died due to heat stress en route to slaughterhouses” amid record heat in 2025, compared to 2024.
FIRE AND ICE: The heatwave also had widespread impacts on the natural world. A wildfire scorched 200 hectares of moorland in Derbyshire, reported the Times. Derbyshire’s fire service said: “The ground is tinder dry and the slightest spark…could soon escalate to a major incident.” Agence France-Presse reported that “Swiss glaciers are set to lose an enormous amount of ice”, noting that this is the “second-earliest arrival on record of the tipping point known as ‘glacier-loss day’”.
UK 2050 farm plan
FARM CHANGES: The UK government launched a 2050 “farming roadmap” for England, setting out aims to make agriculture more resilient to climate change, increase domestic food production and boost nature recovery. The plan is “full of ambition”, but “falls short” on action and delivery, said National Farmers’ Union president Tom Bradshaw in a statement. Meanwhile, the government also announced £47m in funding for peatland protection and restoration schemes.
FOREST LOSS: UK companies may soon be required to “check that their supply chains are free from products linked to illegal land clearances”, reported the Times. The government revived plans for anti-deforestation rules for products such as soya, palm oil, cocoa and rubber, said the newspaper. The rules will initially target goods linked to illegal deforestation, but later move to a “blanket ‘deforestation-free’ standard”, it noted, adding that similar plans in the EU have been repeatedly delayed.
FRAUGHT FUND: UK energy secretary Ed Miliband was “poised to announce” a £400m commitment to the Tropical Forest Forever Facility, but the plan was “shelved over ‘optics concerns’” amid a “bitter row over defence spending”, said the Times. Meanwhile, one of Europe’s oldest and largest trees died after “becoming stressed by a series of hot, dry summers”, reported the Guardian. The Major Oak, which has grown in England’s Sherwood Forest “for at least 1,000 years”, did not produce leaves this year, said the newspaper.
News and views
- OCEAN ACTION: The Our Ocean Conference concluded in Mombasa, Kenya, with more than 300 voluntary commitments from governments, civil-society groups, non-governmental organisations and others, said Carbon Brief. Observers told the outlet that “these pledges must now be backed up by action”.
- HOT SEAS: Record-high global ocean temperatures in June could lead the world to “uncharted territory”, said the Financial Times. Meanwhile, the Independent reported that a species of sea star thought to be extinct was found off the coast of California.
- EU PLANS: The European parliament approved rules to allow the use of gene-edited plants, marking a “major shift” in the EU’s approach to modified crops, reported Bloomberg. Meanwhile, Grilled, a new investigative newsletter, said the EU is “considering an overhaul of how it measures methane emissions from livestock”.
- BRAZIL BLAZES: Last year, fires caused a “significant spike in forest loss” across three areas in Brazil home to Indigenous peoples living in “voluntary isolation”, according to Mongabay. Indigenous leaders told the outlet that fire “affects their productive practices and destroys the biodiversity and vegetation they depend on”.
- DISCLOSURE DISPARITY: The Biodiversity Footprint Company analysed the climate- and biodiversity-related disclosures of “120 of the world’s largest listed companies”. It found that “companies disclose roughly two-thirds of assessed climate information, yet less than one-20th of the equivalent biodiversity information”.
- FRUITLESS: Fruit growers across the US south-western state of Utah “are reporting near-total harvest losses”, reported High Country News. It noted that a warm, dry winter, followed by a “record-breaking spring heatwave”, led orchards to bloom early, but the crop was then “devasta[ed]” by a “series of April freezes”.

‘Up and running immediately’: what’s next for the High Seas Treaty
This week, Carbon Brief speaks to Rebecca Hubbard, director of the High Seas Alliance, about the High Seas Treaty (also known as the agreement on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction, or BBNJ). This interview was conducted at the Our Ocean Conference in Mombasa, Kenya.
This interview has been lightly edited for clarity and length.
Carbon Brief: What connects BBNJ and climate change?
Rebecca Hubbard: The high seas cover half of the planet, or two-thirds of the global ocean. The ocean is essential for many things, including producing oxygen, absorbing carbon and absorbing the enormous amount of excessive heat we’ve produced as a result of burning fossil fuels. The ocean, including the high seas, cannot perform its critical climate-regulating role without healthy populations, without being healthy, and – at the moment – the high seas are not protected.
In fact, only around 1% of the high seas are protected and they’re under immense pressure from shipping, fishing, pollution [and] climate change – both heating and acidification. The High Seas Treaty, for the first time ever, gives us the legal framework to be able to protect the high seas. By being able to protect and better manage the high seas, we are assuring its critical role in protecting us from the worst of climate change.
CB: What were your hopes or expectations coming into this conference?
RH: My hopes were that we would get strong engagement and leadership from African states in the High Seas Treaty and we have seen that, which is really fantastic. There’s been a lot of support, a lot of leadership from African governments on the treaty and on their ambitions to not just complete their ratification processes, but to also start looking at creating marine protected areas. They want to be engaged and involved in leading and delivering those processes and I think that’s really exciting. It’s a great opportunity for the whole world. We can really get some exciting collaborations.
CB: What has been missing from the conversation here?
RH: I actually don’t think much has been missing, because I think there’s been a lot of different conversations. There’s been conversations around the need for finance to implement the treaty and this is something that’s common across all multilateral environmental agreements – certainly no stranger to the climate process. We’re going to need this huge amount of resources to implement the treaty. Where is that money coming from?
CB: We’ve got almost exactly six months until COP1 [the first Conference of the Parties for the High Seas Treaty scheduled for January 2027]. What needs to happen between now and then?
RH: We need as many more countries to ratify as possible. We hope that well over 100 countries will be party to the agreement by COP1, so that they can be at the decision-making table. We need countries to really prepare for that COP, so that they’re ready to really efficiently make the decisions founded off all of the work that we’re done through the PrepCom [preparatory commission] meetings [and] so that we can get the rules of procedure and the subsidiary bodies that are going to be essential to an effective implementation up and running immediately.
There is so much to do and we do not have time to waste with circular negotiations, rehashing resolved issues. We also need countries to continue to prepare for implementation, particularly back in their capitals – establishing inter-ministerial committees, so that you have a cohesive and united approach from governments that reflects a whole-of-government approach. That’s what’s going to be essential for effective implementation.

Proposal for ‘Hyperscale’ data centre in remote Northern Territory demonstrates need for urgent moratorium
SYDNEY, Wednesday 1 July 2026 — The proposal for the ‘Project Ares’ data centre in remote Northern Territory, which would be powered by off-grid gas and renewables, has prompted renewed calls from Greenpeace for an urgent moratorium, citing serious concerns about emissions and environmental harm.
The application for the project under the EPBC Act reveals the gas-fired generation for the project would be approximately 1,038MW at full build-out, which would more than double the NT’s current gas-fired generating capacity.
A recent report by Greenpeace Australia Pacific and independent expert Ketan Joshi, Energy Vampires: the AI data centres draining Australia, revealed how the frenzied rollout of AI data centres in Australia is set to derail the renewable energy transition, entrench gas and turbocharge climate pollution.
Solaye Snider, Campaigner at Greenpeace Australia Pacific, said: “Proposals like Project Ares, which would have significant off-grid gas powered generation and emissions, should not be moving along while there are still zero binding regulations to limit the impacts of AI data centres on our communities and environment.
“This hyperscale project proposes massive new off-grid gas infrastructure, making a mockery of the Federal Government’s unenforceable ‘expectations’ that data centres will cover their own power use with renewables. Communities will pay the price for the data centre industry’s endless hunger for energy at any cost.
“This proposal also raises serious questions about where this new gas would come from. Could it come from fracking the Beetaloo? Communities deserve to have the full picture before this project is approved.
“The Australian Government is asleep at the wheel when it comes to the rapid roll-out of AI data centres. We need an urgent moratorium on the construction and approval of new data centres, so our government can take appropriate time to legislate the regulations and safeguards we so desperately need.”
