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.

Britain’s energy regulator is poised to announce another steep quarterly price‑cap, signalling that electricity bills will stay high for the foreseeable future. The rise is driven not just by volatile wholesale prices but by a cascade of non‑commodity costs that are set to balloon over the next decade.Why the Next Ofgem Price Cap Is Likely to Remain ElevatedEnergy consultant Cornwall Insight predicts the typical household electricity bill will reach £1,850 this quarter – an increase of £209 from the previous period. The regulator’s messaging will likely cite the ongoing disruption of the Strait of Hormuz and the mitigating effect of new wind and solar generation.Cost Drivers Behind the Rising Electricity BillsWholesale electricity now accounts for only 30% of the bill, down from 90% a few years ago.Non‑commodity charges – grid upgrades, carbon taxes, warm‑home discounts and nuclear subsidies – dominate the cost structure.Network Use of System charges are projected to jump from £7.6bn this year to £12.1bn by 2029‑30, a ~60% increase.Balancing costs could rise from £2bn annually now to as much as £8bn by 2030.Industry leaders warn that even a 50% cut in wholesale prices would still leave bills 20% higher due to fixed non‑commodity costs.Broader Economic and Industrial ImplicationsHigh electricity prices threaten UK manufacturing competitiveness, as highlighted by the CBI and Energy UK. The Climate Change Committee stresses that cheaper power is essential to accelerate heat‑pump and electric‑vehicle adoption, yet the current cost trajectory delays those decarbonisation gains.What Transparent Medium‑Term Forecasts Could ChangeAnalyst Ben James estimates an average increase of £79 per household between 2025 and 2030. If Ofgem published similar medium‑term models, policymakers could better allocate levies, decide on taxation versus direct subsidies, and provide households with clearer expectations. Greater openness would also sharpen the political debate on who should bear the rising grid and balancing costs.

Court of First Instance Imposes Two-Year Sentence on Sonia DahmaniThe Tunisian Court of First Instance delivered a verdict on Friday, sentencing Sonia Dahmani to two years in jail for remarks made during a 2023 radio interview that criticised prison conditions. The decision was announced by her lawyer Sami Ben Ghazi to AFP.Accumulated Prison Terms and Legal ChargesCurrent sentence: 2 years for prison‑condition criticism.Previous convictions: 18 months in May 2024 for a sarcastic TV comment on migrants, and an additional 18 months in April 2024 for remarks about cemeteries and buses reserved for Black people.Overall, Dahmani faces prosecution in five separate cases, all rooted in statements deemed violations of Decree 54.Escalating Repression Under Saied’s Decree 54Decree 54, enacted in 2022, criminalises the spread of “false information” and has been widely condemned by human‑rights groups as a tool for political repression. Since President Kais Saied seized power in the July 2021 coup, the law has been invoked to target lawyers, journalists and activists, intensifying a climate of fear.Human‑rights organisations note a sharp increase in arrests and sentencing, linking the crackdown to broader anti‑migrant rhetoric that has sparked violence against sub‑Saharan migrants.Potential International Response and Future Legal BattlesDahmani’s lawyer has lodged an appeal, indicating that the case may ascend to higher courts. International watchdogs are likely to monitor the appeal closely, and renewed diplomatic pressure could arise from EU and UN bodies concerned with freedom of expression.If the appeal fails, the cumulative sentences could keep Dahmani detained for several years, further exemplifying the tightening of dissent in Tunisia and potentially prompting renewed calls for sanctions or conditional aid from foreign partners.

The Call for Urgent Action Climate campaigners have called on the UK government to urgently start installing air conditioning units in schools, care homes, and places where vulnerable people live. This call comes as the country experiences record high temperatures, with over 3,000 people dying from heat-related causes in 2022. The Impact of Heatwaves The UK has warmed by about 1.5C relative to the pre-industrial average, with Europe warming faster than any other continent. The majority of English homes overheat during the summer, making it essential to take measures to mitigate the effects of heatwaves. The Role of Air Conditioning Studies have shown that air conditioning can cut heat-related deaths by 75%. However, the use of air conditioning units is not without its challenges, as they consume a lot of electricity. To address this, experts suggest pairing air conditioning with solar power, which can provide a sustainable and green solution. The Way Forward Some experts argue that air conditioning should be prioritized for those who need it most, such as the elderly and young children. Additionally, investing in community solutions like cool spaces, such as community centers and churches, can provide respite for those at risk. The government has announced plans to cover grants for heat pump installation, including those with a cooling function, but experts argue that more needs to be done to increase energy supply on the grid. The Future Outlook As the climate continues to get hotter, the need to adapt properties to cope with extreme temperatures is becoming more urgent. The UK government must take action to address the issue, including investing in green energy and implementing measures to keep homes cool during the summer. This can include installing shutters, retrofitting homes with insulation, and promoting the use of air conditioning units in vulnerable settings.

Hundreds of homes in Kent and East Sussex were left without water after a technical failure at South East Water's pumping station, a problem amplified by an intense heatwave and rising demand.Outages Spike Across Kent and East Sussex Amid HeatwaveThe supply disruption began on Saturday and peaked on Sunday, affecting rural villages on higher ground.~800 properties in the Kent villages of Charing, Challock and Molash lost water.~168 homes in Eastbourne, East Sussex, were affected on Sunday afternoon.At least 250 homes remained without water on Monday.South East Water attributed the issue to “increased demand across our network” and a “technical failure at our pumping station near Charing”.Financial and Regulatory Fallout for South East WaterThe utility faces a pending £22 million fine from regulator Ofwat for repeated supply disruptions.Following a parliamentary committee’s criticism, chief executive David Hinton announced his resignation and the group’s chair also stepped down.Additional costs include emergency bottled‑water stations and temporary water deliveries to affected households.Implications for Regional Water Management and Climate ResilienceThe UK has one of the highest per‑capita daily water‑use rates in Europe—about 142‑150 litres per person. Government targets aim to cut usage by 20 % by 2038 and reach 110 litres per person by 2050.A recent House of Lords report warns of potential shortages of up to 5 billion litres per day by 2055 without a nationwide demand‑reduction campaign, rainwater harvesting, and grey‑water recycling.What’s Next for Supply Reliability and Policy Targets?South East Water has re‑opened a bottled‑water station at Challock Village Hall and is delivering water to customers unable to collect it.The company urges residents to “space out heavy water tasks” to maintain pressure, especially on higher‑elevation properties.Long‑term, regulators and policymakers are expected to tighten performance standards, accelerate infrastructure upgrades, and promote public‑water‑conservation initiatives to meet national targets.

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.

The Lead: Michigan's Climate Reality ShiftMichigan is experiencing a dramatic shift in its climate patterns, with the state now facing unprecedented extreme weather events that challenge its previous reputation as a climate haven. From record-breaking tornadoes to devastating flooding, Michigan's communities are confronting the tangible impacts of climate change with increasing frequency and severity.The Event Details: Unprecedented Weather PatternsThe tornado that hit west Ann Arbor at 1.45am on April 15, 2026, is just one example of the extreme weather plaguing Michigan. This year alone, the state has already experienced 15 tornadoes—matching its annual average—with March seeing communities across nine counties hit by two rounds of devastating tornadoes that killed four people, including a 12-year-old boy. These tornadoes marked the earliest EF-3 tornado to hit the state in documented history.The tornado outbreaks follow some of the worst flooding the state has seen in decades. Last month, several Michigan dams and levees were at risk of failure, prompting an evacuation order in Cheboygan in the north of the state. Federal Emergency Management Agency (Fema) officials have been assessing the fallout across 30 Michigan counties.These events follow the 2025 freezing rain storm that destroyed millions of acres of trees in northern Michigan, rendering hundreds of miles of electricity infrastructure useless and cutting power for weeks to thousands of people.The Data Analysis: Mounting Economic CostsThe financial toll of Michigan's climate-related disasters is substantial. The failure of the Edenville and Sanford dams in 2020 resulted in 10,000 people evacuated and 2,500 homes and businesses damaged or destroyed at an estimated cost of $175 million. The cost of rebuilding these dams and three others that failed is estimated at almost $400 million.Lynn Coleman, who runs a campground near the Edenville dam, has faced significant financial challenges. "The business has lost an average of $35,000 a year. Now, with the rebuild [of the dam], we're hit with just under $30,000 a year in lake assessment [fees] and that goes for the next 40 years."In Ann Arbor, the closure of the Veterans Memorial ice rink—used by roughly 60,000 people last year—will result in both revenue and social impacts for the community. The city's access to city-owned ice rinks will be cut in half next season since this is one of just two such facilities.The outdoor recreation sector, essential for thousands of small businesses, faces significant challenges as floods threaten to slow the spring season's activities. Campgrounds, trails, equestrian and other facilities across 22 Michigan counties face huge and costly cleanup operations.The Impact Analysis: Changing Climate PerceptionsMichigan's experience challenges the perception of the Great Lakes region as being "climate proof" or a climate haven. The state's position in the transition boundary of the jet stream between warm, moist air from the south and cold, dry air from Canada makes it particularly vulnerable to extreme weather events."When you have warm, moist air that clashes with dry air, you get a very sharp boundary in temperatures that will cause severe weather. And that's what we've seen," explains Lisa DeChano-Cook, a professor at Western Michigan University's school of environment, geography and sustainability. "We also have a strong temperature contrast between the Great Lakes water temperatures and the Gulf moisture. More precipitation can come down, and we can have more extreme outcomes."The changing climate patterns are affecting not just the physical environment but also the social and economic fabric of Michigan communities. The combination of property damage, business disruptions, and increased costs for infrastructure improvements is creating long-term challenges for residents and local governments.The Prediction: Future Climate Outlook for MichiganResearchers indicate that Michigan's extreme weather events are likely to continue and potentially intensify. The weakening of the polar jet stream due to warmer temperatures in the Arctic is causing it to bend more to the north and south, leading to more extreme weather events across larger areas including the Great Lakes region."It's not necessarily new, and yet I think it is linked to climate change," said DeChano-Cook of the severe weather facing the state. "We're seeing this waviness in the jet stream much more often in the spring and the fall than we used to."As Michigan continues to experience these climate impacts, the state will likely need to invest more in infrastructure resilience, emergency preparedness, and climate adaptation strategies. The economic and social costs of inaction may far exceed the investments needed to prepare for and mitigate the effects of a changing climate.

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.
