Heatwaves have grown hotter and stronger as the planet has warmed, making what doctors call a "silent killer" even more dangerous. How worried should we be about heat – and how can we stay safe as the climate changes?The Human Cost of Extreme HeatHot weather kills an estimated half a million people each year. The average annual death toll is greater than that from wars or terrorism, but smaller than that from cars or air pollution.Despite this, heat is rarely listed as the cause of death. That's because extreme temperatures are largely indirect killers. Most heat victims die early from illnesses – such as heart, lung and kidney disease – that are made worse in warm weather.The Physiological Impact of Heat StressHigh heat stresses the human body, sending the heart and kidneys into overdrive as they work to keep the body cool. The added strain – particularly for those with chronic illness – can prove fatal even before heatstroke hits.There are also secondary health effects from high heat. Heatwaves lead to more accidents, dirtier air, bigger wildfires and more frequent power outages, all of which can increase the burden on health systems.The Critical Role of Nighttime TemperaturesWhen days are too hot to function and nights are not cool enough to recover, the body is unable to rest. This compounds the damage done during scorching days.In many European countries, meteorologists describe nights with temperature minimums above 20°C as "tropical", while in Spain, which is more familiar with extreme heat, they call nights above 25°C "equatorial" or "torrid". In recent years, they have informally introduced a new category for night-time temperatures above 30°C: "hellish".Identifying Vulnerable PopulationsPeople who are forced to be outdoors in scorching weather – builders, farmers, rough sleepers etc – are most likely to suffer from heat exhaustion and the heatstroke that can follow.But older people, and particularly those with underlying illnesses, make up the bulk of heat-related deaths. Women are more likely to die from heat-related causes than men. Poorer people – who are less likely to have air conditioning, well-insulated homes or access to green spaces – are also at greater risk.The Humidity FactorSweat is the body's best defence against heat, lowering internal temperatures as it evaporates. But when humidity is high and the air hot and sticky, the body struggles to cool down because sweat clings to the skin. The effect this has on perceived temperatures can be equal to several degrees, enough to spell the difference between life and death.Climate Change and Escalating HeatwavesMore than a century's worth of fossil fuel pollution has clogged the atmosphere, trapping sunlight and heating the whole planet. Average global temperatures have risen by about 1.3°C since preindustrial times – and land temperatures by even more – which has pushed the baseline higher and made punishing extremes far more common.There is also some evidence that the climate crisis is making heatwaves worse by weakening the jet stream. Scientists think this is increasing the occurrence of heat domes, which are areas of high pressure and heat that get stuck over a region for days or even weeks.The Net Effect of Rising TemperaturesCold weather kills far more people than hot weather today, even in warm regions such as sub-Saharan Africa and south Asia. But as temperatures rise, the number of deaths from heat is projected to grow much faster than the number of lives saved from milder cold. When scientists modelled this in 854 European cities, they found a net increase in temperature-related deaths under all emissions scenarios, even accounting for how people adapt.Adapting to a Hotter FutureCutting fossil fuel pollution is the biggest step that can be taken to stop heatwaves from getting even hotter, along with protecting forests and wetlands that suck carbon dioxide out of the atmosphere.Urban planners have called for cities to be redesigned so they have less concrete and fewer cars, and more parks and water. This can negate the urban heat island effect, which makes cities hotter than their rural surroundings.Buildings with air conditioning or passive cooling can bring down death tolls, as can strong healthcare systems and swift emergency warnings.The Air Conditioning DilemmaAir-conditioning units increase planet-heating emissions if the power they consume is generated by burning fossil fuels, as it mostly is today, but their pollution is falling as countries clean up their electricity grids. Some experts cite the scale of the heat-related death toll as a worthy reason to use more air conditioning – particularly for the most vulnerable groups – even if it pushes temperatures higher.This year, the UK's Climate Change Committee (CCC) recommended that air conditioning be installed in all care homes and hospitals within the next 10 years, and in all schools within 25 years.Personal Safety StrategiesThe simplest advice is to stay out of the heat: avoid going outside during the hottest parts of the day, and stay in the shade if you have to. To keep your home cool, close windows during the day and open them after dark, when outdoor temperatures fall below inside temperatures. Cover windows with blinds or curtains to block out direct sunlight.Doctors also recommend drinking water frequently, wearing loose clothing and checking on vulnerable people in your community.

The Historic Temperature Milestone and Ongoing HeatwaveA temperature of 33.5°C was recorded at London’s Heathrow airport on Monday lunchtime, shattering the previous May record set in Camden Square in 1922 and last matched in Tunbridge Wells and Regent’s Park in 1944. The Met Office expects temperatures to climb further to 35°C on Tuesday, with highs of 31°C forecast for Wednesday and 30°C on Thursday. Overnight temperatures also broke the UK’s highest minimum May temperature, with Kenley airfield recording a low of 19.4°C on Sunday.Climate Adaptation Urgency and Health RisksThe record-breaking heat underscores the growing impact of climate change on British life. Dr Chloe Brimicombe, a climate researcher at the University of Oxford, called it 'a reminder of how climate change is impacting our lives in the UK. It highlights the urgency of recent calls for heat adaptation.' Amber heat health alerts were issued on Friday, indicating a possible risk to life, particularly for the elderly, pregnant women, and those with underlying illnesses. Experts describe heat as a 'silent killer' because many related deaths go uncounted in official statistics; last summer, scientists attributed two in three heat-related deaths in European cities to climate breakdown.Policy Recommendations for a Hotter FutureLast week, the UK’s Climate Change Committee warned that British homes, hospitals, and schools are ill-equipped for the projected temperature rise. Its recommendations include installing air conditioning in all care homes and hospitals within 10 years and in all schools within 25 years, as well as setting maximum working temperatures for indoor and outdoor environments. Gareth Redmond-King of the Energy & Climate Intelligence Unit stressed that 'cutting those emissions to net zero is the only way to halt climate change and limit the danger,' but added that adaptation is equally critical. The current heatwave is driven by high pressure over the country, caused by sinking, compressing, and heating air, with the risk of more extreme heat amplified by the expected arrival of El Niño later this year.

Executive Overview: BHP’s Climate Commitment Takes a TurnThe latest Full Story podcast, sourced from the Guardian’s BHP Files investigation, discloses a previously hidden internal memo that signals a decisive pull‑back on the company’s public climate pledges. While BHP has long marketed itself as a leader in mining sustainability, the leaked document suggests a strategic retreat that could reshape its emissions roadmap.Leaked Internal Memo Details the Strategic Pull‑backThe memo, dated May 2026, outlines senior executives’ concerns about the feasibility of meeting previously announced emissions targets. Key points include:Reassessment of the 2025 net‑zero timeline.Prioritisation of short‑term shareholder returns over long‑term decarbonisation projects.Recommendations to delay or cancel several green‑technology investments.These revelations contrast sharply with BHP’s external communications that have highlighted ambitious climate goals.Financial Stakes Highlighted by the BacktrackAlthough the memo does not disclose specific monetary figures, analysts note potential market implications:Investor confidence could waver if the backtrack undermines BHP’s ESG credentials.Potential re‑valuation of sustainability‑linked financing arrangements.Risk of heightened scrutiny from regulators and climate‑focused shareholders.At present, no concrete share‑price movement has been reported, but the narrative shift is likely to influence future financial assessments.Implications for the Mining Sector and Global Climate GoalsThe internal reversal sends a ripple through an industry already under pressure to align with the Paris Agreement. If BHP, a benchmark miner, scales back, other firms may feel emboldened to reassess their own climate commitments, potentially slowing progress toward sector‑wide emissions reductions.Future Trajectory: What BHP’s Next Moves Could MeanStakeholders will watch closely for BHP’s official response. Possible scenarios include:Re‑affirmation of climate targets with revised, more attainable milestones.Increased transparency around decarbonisation investments to restore investor trust.Further internal reviews that could either reinforce or completely abandon the current climate strategy.The outcome will shape not only BHP’s reputation but also the broader narrative around corporate climate accountability in heavy‑industry sectors.

The Jimblebar Beneficiation Project: A Missed Opportunity for DecarbonizationBHP has quietly abandoned plans for a major iron ore processing facility near its Jimblebar open-cut mine in the Pilbara. The project, which was well advanced in 2025, aimed to improve the purity of iron ore to meet global demand, particularly from China. Despite being internally rated as having "excellent social value" and being "well-aligned" to shareholder-endorsed climate plans, the mining giant decided to cancel all further work on the plant.The Economic Trade-off: Marginal Returns vs. Climate GoalsThe decision to scrap the Jimblebar plant was driven by a strict assessment of marginal economics. BHP determined that the project would struggle to compete for capital against other potential investments. This cancellation is part of a broader pattern where the company is either shelving or delaying major projects designed to reduce emissions, including a 50-megawatt solar and 20MW battery project that had board approval.Capital Allocation: The miner is prioritizing projects with higher immediate returns over those that offer long-term environmental benefits.Fleet Strategy: Despite pledging to electrify its fleet, BHP has continued purchasing polluting diesel trucks for Pilbara operations.Quantifying the Impact: Scope-Three Emissions and Market PremiumsThe Jimblebar facility was not just a logistical upgrade; it was a strategic tool for decarbonization. By providing higher quality iron ore, the plant would have allowed steelmakers to reduce their emissions intensity, which is one of the cheapest methods for the industry to cut carbon output.The economic and environmental stakes were significant:Emission Reduction: The project was estimated to reduce scope-three emissions by 1.7m tonnes a year.Comparative Impact: This reduction is equivalent to taking more than 350,000 cars off the road, representing about three-quarters of the entire annual emissions from BHP’s Western Australian iron ore division.Market Premium: Higher quality ore allows BHP to charge customers a premium, creating a potential win-win scenario that was ultimately deemed too marginal.Broader Implications for Australia's Safeguard MechanismThe leaked documents, dubbed the "BHP files," raise serious questions about the efficacy of Australia’s Safeguard Mechanism. This federal policy requires the country's largest polluting industrial facilities to cut greenhouse gas emissions intensity year on year. BHP's decision to delay or cancel green investments suggests that the current policy framework may not be strong enough to compel major miners to prioritize decarbonization over short-term profitability.Future Outlook: The "Net Zero" DilemmaBHP's recent actions indicate a potential shift in its timeline for achieving net-zero goals. By war-gaming options to significantly delay major investments, the company is signaling that its 2050 emissions target may be more aspirational than operational in the near term. Investors and climate advocates will be closely watching whether BHP can reconcile its climate commitments with its capital allocation strategy as global pressure mounts.

BHP’s Diesel Truck Spend Undermines Its 2040 Decarbonisation GoalBHP has continued to allocate hundreds of millions of dollars to diesel haul trucks in the Pilbara, despite internal analysis flagging the move as “misaligned” with its climate‑change strategy.Continued Procurement of Diesel Trucks for Pilbara SitesThe mining giant authorised the purchase of 62 new diesel trucks for the Jimblebar mine, with an estimated cost exceeding $500m. The trucks are intended to operate at Jimblebar and the planned Ministers North mine, where diesel haulage is projected to dominate direct emissions through at least 2041.Jimblebar fleet refurbishment in 2022 aimed to extend service life by 60,000 hours (≈8 years).Original plan targeted full electric replacement in the 2030s.2023 decision shifted to new diesel purchases, citing a “material reduction in cost”.Financial and Emissions Footprint of the Diesel FleetThe $500m outlay represents a significant capital investment in a technology the company has publicly pledged to phase out. Documents note the purchase aligns with a “40% diesel displacement by 2040” target, yet diesel haulage remains the largest source of BHP’s direct greenhouse‑gas emissions in Western Australia.Strategic Implications for BHP’s Climate CommitmentsAustralia’s biggest diesel consumer, BHP’s reliance on diesel trucks threatens the credibility of its broader decarbonisation roadmap, which calls for full diesel displacement by 2040. The company has warned regulators that battery‑electric truck technology is not yet ready for large‑scale deployment, a stance that delays the transition timeline outlined in its 2024 climate action plan.Future Outlook: Electrification Delays and Regulatory PressureWhile BHP claims to be partnering with equipment manufacturers to trial two 240‑ton battery‑electric haul trucks and four electric locomotives, the company acknowledges that “technology is not advanced enough to scale to an operational fleet.” Continued diesel procurement may invite heightened scrutiny from the Environmental Protection Authority and investors demanding alignment with climate targets.

The LeadA leaked internal memo from BHP, the world's largest mining company, has revealed a significant reversal in the company's climate strategy. The document shows that BHP has slammed the brakes on several key climate initiatives, despite public commitments to environmental sustainability. This revelation comes at a critical time when the mining industry faces increasing scrutiny over its environmental impact and role in climate change.The Climate Strategy ReversalThe internal memo, obtained by The Guardian, outlines a dramatic shift in BHP's approach to climate initiatives. According to the document, the company has paused or significantly reduced funding for several key projects aimed at reducing its carbon footprint. These include scaling back investments in renewable energy projects, delaying the transition to electric mining vehicles, and reconsidering targets for reducing Scope 3 emissions, which account for the majority of the company's carbon footprint.The memo reportedly expresses concerns about the financial viability of these initiatives and suggests that the company needs to focus on short-term profitability rather than long-term environmental goals. This represents a significant departure from BHP's previous public stance on climate change, where the company had positioned itself as a leader in sustainable mining practices.Financial ImplicationsThe decision to scale back climate initiatives is likely to have significant financial implications for BHP. While the company may save money in the short term by reducing investments in green technologies, it risks facing long-term costs from regulatory penalties, carbon taxes, and potential divestment by environmentally conscious investors.The mining industry as a whole is facing increasing pressure to address its environmental impact. With global temperatures rising and governments implementing stricter environmental regulations, companies that fail to adapt their business models may find themselves at a competitive disadvantage in the coming decades.Industry-Wide RepercussionsBHP's decision to slow its climate push could have far-reaching implications for the mining industry. As one of the largest and most influential mining companies, BHP's actions may set a precedent for other firms in the sector. This could lead to a broader slowdown in climate initiatives across the industry, potentially undermining global efforts to reduce emissions from the mining sector.The mining industry is responsible for a significant portion of global greenhouse gas emissions, both directly through operations and indirectly through the extraction and processing of fossil fuels. Any reduction in climate action by major players like BHP could make it more difficult for the world to meet its climate targets under the Paris Agreement.Future OutlookLooking ahead, BHP's climate strategy reversal may prove to be a short-term decision with long-term consequences. As the global economy continues to transition toward sustainability, companies that fail to invest in green technologies may find themselves struggling to compete in a low-carbon future.Investors, regulators, and consumers are increasingly demanding that companies take meaningful action on climate change. BHP will need to balance these expectations with the financial realities of operating in a volatile commodity market. The company's future success may depend on its ability to develop a climate strategy that addresses both environmental concerns and business objectives.

The Climate Reversal of a Mining GiantThe revelation that BHP cancelled and delayed commitments to act on the climate crisis should be a wake-up call. It matters in its own right: millions of tonnes of additional heat-trapping pollution will go into the atmosphere, adding to climate harm and making Australia's climate targets that much harder to reach.It also matters for the influence the world's biggest miner could have in accelerating use of technology needed to cut pollution from major industrial operations.Delayed Renewable Projects and Diesel DependenceBHP shelved the first big investment planned under its decarbonisation plan – a huge solar farm – after it was approved and funded by its board. A much larger solar, wind and battery development that would have run most of its inland operations in northern Western Australia has been delayed for at least five years.BHP has also doubled down on using diesel-powered trucks, despite a promise to switch to a fleet of electric vehicles running on renewable energy. Internal documents acknowledge this is inconsistent with its climate pledges.The Scale of BHP's Environmental ImpactBHP is famously known as the Big Australian – a reflection of its success and scale since its origins mining silver and lead in Broken Hill 140 years ago. It remains at or near the top of lists of the country's most profitable companies.But it is also a historic, global-scale polluter, mostly thanks to its mining of coal. Its extraction of that dirty fuel means it has been in the upper echelon of corporate emitters since industrialisation.The thinktank InfluenceMap lists it as the 31st biggest cumulative contributor to the climate crisis, and the 10th biggest among companies owned by private investors.Over the past 140 years, it has been responsible for more than 11bn tonnes of carbon dioxide pumped into the atmosphere, counting the pollution released when its customers use its products. That's equivalent to about 25 years of Australia's current annual emissions.Emissions Discrepancies and Financial CapacityThe company says it is acting – that its emissions are down 36% since 2020, putting it ahead of its target of a 30% reduction by 2030. But the detail here matters. The claimed cut is due to power purchase agreements signed for some grid-connected renewable energy projects, particularly in Chile, and the suspension of its struggling Western Australian nickel operations.Its direct onsite emissions, mostly from burning diesel, continue. And its annual report shows its scope-three emissions – those that result from the use of its products – have increased by 7% since the turn of the decade. The scale of that increase – more than 25m tonnes a year – dwarfs the reduction the company claims it has made.The company's own estimates suggest that its full decarbonisation could cost US$7.5bn over the next 25 years. It brings in the equivalent revenue in less than six months from its WA operations alone.Government Policy and Corporate ResponsibilityOne reason BHP hasn't invested more heavily in emissions reduction might be that the Australian Labor government is sending mixed messages to big miners even as it pledges the country will reach net zero emissions by 2050.Mining companies receive more than $4bn a year in rebates on the cost of diesel that are not offered to households and small businesses. BHP is the biggest beneficiary. According to the thinktank Clean Energy Finance, the fuel tax credit scheme lowered its fuel bill by about $620m last year.Making fossil fuels cheaper is a strange way to encourage the uptake of electric trucks running on renewable energy. It also works against the goals of a government policy that requires big industrial sites, including those operated by BHP, to cut emissions year-on-year.

Deadly Blast at Liushenyu Mine Shuts Down Operations State media Xinhua reported that a gas explosion ripped through the Liushenyu mine in Qinyuan county, Shanxi province on Friday, killing at least 90 people. The blast struck while 247 workers were underground, making it the deadliest mining disaster in China in more than a decade. Casualties, Workforce and Production Figures Highlight Scale Deaths confirmed: 90 Workers on shift at time of explosion: 247 Shanxi’s 2025 coal output: > 1 billion tonnes (≈ one‑third of national production) China’s share of global coal consumption: > 50% The province accounts for almost a third of China’s total coal extraction, meaning any shutdown reverberates through national energy supplies. Safety Lapses and Environmental Stakes Prompt Nationwide Scrutiny China’s coal mines have long been labeled among the world’s deadliest due to weak regulation, corruption, and inadequate safety standards. The explosion followed a carbon‑monoxide alert that reportedly indicated gas levels exceeding safe limits. CGTN confirmed the mine’s overseer has been arrested, and President Xi Jinping ordered all regions to intensify accident‑prevention measures. Beyond the human toll, the incident raises concerns about China’s ability to balance its status as the world’s largest coal producer with its commitments to reduce greenhouse‑gas emissions. The disaster could accelerate calls for a faster transition to renewable energy sources. Tightened Oversight Likely to Reshape China’s Coal Sector Analysts expect the central government will impose stricter safety inspections and possibly limit production at high‑risk mines. Potential outcomes include: Increased funding for modern monitoring equipment to detect hazardous gases. Revised penalties for safety violations, aiming to deter corruption. Accelerated investment in clean‑energy projects as part of China’s carbon‑neutrality roadmap. While short‑term coal output may dip, the long‑term effect could be a more regulated, safer industry that aligns with global climate goals.

Executive Summary of the UK‑EU Trade Pitch The UK is positioning a single market for goods as the flagship of its effort to re‑integrate trade with the European Union. While the Cabinet Office’s EU‑relations chief Michael Ellam presented the idea in Brussels, EU officials rejected it, preferring a customs union or European Economic Area alignment—options that clash with Prime Minister Keir Starmer's stated red lines. UK Proposes a Goods‑Only Single Market to the EU During recent visits to Brussels, Ellam outlined a framework that would allow tariff‑free movement of goods while keeping the UK outside the EU’s customs union and free‑movement rules. Sources told the Guardian that EU diplomats instead suggested a broader customs union or EEA economic alignment, both of which would require acceptance of free movement of people—something Starmer has ruled out for his lifetime. £9 bn Annual Boost from Proposed SPS and ETS Deals Negotiations include a sanitary‑phytosanitary (SPS) agreement for food and drink. An emissions‑trading scheme (ETS) linkage is also on the table. The Cabinet Office estimates these two measures could add £9 bn a year to the UK economy by 2040. Political Constraints Shaping the UK‑EU Trade Dialogue Labour’s ambition to deepen economic ties runs into the same obstacles that stalled former Prime Minister Theresa May's Chequers plan—namely, the need for a “common rulebook” without free movement of people. EU officials warn that granting the UK preferential treatment could fuel Eurosceptic sentiment in member states, potentially influencing upcoming elections such as the 2027 French presidential race. Domestically, the upcoming Makerfield by‑election adds pressure, with Labour’s Andy Burnham signalling a focus on domestic issues rather than a return to the EU. What the Next Summer Summit Could Deliver The tentative summit, pencilled in for 13 July, is expected to focus on three priority deals: a veterinary agreement, the SPS‑ETS package, and a youth mobility scheme. While the single‑market for goods proposal appears stalled, progress on the food‑trade and emissions deals could still materialise, providing a modest economic uplift and a diplomatic signal that the UK remains a constructive partner despite broader political disagreements.
