The Energy Imbalance Iran is facing more energy constraints as its summer season begins, with the widespread use of air conditioning and other needs during hotter months contributing to an imbalance between supply and consumption. Government's Limited Options For decades, successive Iranian governments have kept utility bills well below supply costs for households and offices through a mix of implicit oil-and-gas subsidies, administered tariffs, state-controlled pricing, and sometimes direct financial support. However, the negative impacts of the war with Israel and the United States on the economy mean the government has fewer tools at its disposal to deal with an energy crisis this summer. Data Analysis Despite having the world's third-largest proven crude oil reserves, Iran will have to import fuel again as demand outpaces refinery output. The administration's attempts to tackle the subsidies burden due to a mounting budget crunch have resulted in only limited increases in petrol through a complex three-tiered pricing system. Most users of Iranian-made vehicles have access to 60 litres (15.85 US gallons) per month of subsidised petrol at 15,000 rials (0.8 cents) and another 100 litres (26.42 gallons) at 1.6 cents. Any use over tier 1 and tier 2 is priced at 50,000 rials (around 1.4 cents) and Iranians are allowed a maximum of 30 litres of fuel per day under any of these prices schemes. Impact Analysis The Iranian government is running similar schemes for natural gas, electricity and urban water, with fears of social unrest making them averse to any sudden price hikes. There appears to be little the government can do to bridge the divide between lower energy production and growing demand for subsidised fuel, illustrated by the perpetual queues at petrol stations since the start of the war. Prediction The situation has worsened during the war, with strikes on Iranian energy facilities seeing Iran's gasoline production capacity drop marginally from 115 million litres (30.37 million gallons) per day to 110 million litres (29.06 million gallons). Meanwhile, consumption has jumped from 10 million litres (2.64 million litres) in 2025 to 140 million litres this year (36.98 million litres). US President Donald Trump's threats of more strikes on power plants have heightened fears of further blackouts and gas shortages this summer, meaning the energy crisis is likely to continue in the coming months.

The Looming Public Health Crisis in a Warming UKAs the UK experiences unprecedented record-high May temperatures, a severe inequality is defining how citizens cope with extreme heat. While air conditioning (AC) adoption is surging among the wealthy and healthy, disabled and chronically ill individuals—who face the highest mortality risks during heatwaves—are being systematically priced out of life-saving cooling infrastructure.The Great Cooling DivideThe narrative around British summers has fundamentally shifted from a seasonal novelty to a survival challenge. While 4 million households now boast some form of AC, this statistic masks a grim reality. Affluent homeowners can afford tens of thousands of pounds for built-in cooling systems. In contrast, disabled individuals—who are disproportionately represented in lower-income brackets and rental markets—are left relying on inadequate fans or barred from modifying their rented properties. The ability to regulate body temperature during a heatwave has effectively become a luxury.The Stark Economics of Surviving Extreme HeatThe financial and physical toll of rising global temperatures is quantifiable and deeply alarming. The market is reacting to climate change by squeezing the most vulnerable:4 million: The number of UK households with AC, double the amount from just three years ago.17%: The surge in the cost of AC units in the UK over a single month due to spiking demand.4,500+: The number of excess deaths in Britain during the 2022 heatwave when temperatures exceeded 40C.Infrastructure Inequality and the VulnerableThis crisis extends far beyond private residences. Vulnerable populations residing in care homes, hospitals, schools, and prisons are entirely at the mercy of institutional budgets and government funding. Furthermore, minority ethnic groups and low-income families are disproportionately housed in urban developments prone to dangerous overheating. The current market-based approach to climate adaptation is creating a fatal two-tiered system where marginalized communities are left defenseless against environmental extremes.The Political Weaponization of Climate AdaptationLooking ahead, the failure to provide equitable climate adaptation will trigger not only a public health catastrophe but a severe political crisis. As the physical environment destabilizes, right-wing populists are already leveraging extreme weather to rile public anger against green legislation. Figures such as Nigel Farage and Tony Blair have begun attacking net-zero initiatives and heat pump subsidies. To prevent the political weaponization of the climate crisis, governments must urgently pivot toward systemic solutions: installing AC in public care facilities, creating municipal cool spaces, revolutionizing social housing design, and aggressively reducing emissions to treat the root cause of the warming.

The Escalating Heat Crisis in EuropeMeteorological summer has begun with scorching heat that struck before spring was even over. Western Europe, now mostly free from last week's heat dome that shattered temperature records for May in the UK and Ireland, is already bracing for another sweltering summer. The World Meteorological Organisation has warned everyone to prepare for the imminent return of the warming weather pattern El Niño, which will likely exacerbate the situation.The Human Cost of Rising TemperaturesScientists are still calculating the death toll from the latest bout of hot weather, but early modeling suggests 250 extra deaths in the UK alone on the weekend before temperatures peaked. The full death toll is expected to be particularly high because the heat struck before people had properly adjusted their behavior to stay safe. Heat kills more people in Europe than almost any other issue, from crime to terror attacks, with many tens of thousands of early deaths each year. A study in September attributed two in every three heat deaths in European cities to climate breakdown.The Policy Gap in Heat PreparednessDespite the growing threat, simple steps to save lives—many of which are cheap or would pay for themselves in the long run—are largely absent from national politics. A survey of European countries in 2024 found just 21 of 38 had heat-health action plans. Efforts to transform carparks into green spaces are often still considered radical. This collective denial persists even as the scientific evidence mounts about the dangers of extreme heat.Climate Shelters: A Growing ResponseIn response to the crisis, climate shelters have emerged as a critical adaptation strategy. These spaces, where people can take refuge, cool down, and drink water, have become popular in Barcelona, where they've grown to more than 400 since the local program began in 2020. The concept has now spread across Spain, with Pedro Sánchez, the socialist prime minister, announcing a national network of climate shelters as part of a "state pact to tackle the climate emergency." Cities across Europe are adopting similar approaches, with formal cooling zones appearing from Paris to Vienna.Regional Disparities in Heat VulnerabilityWhile southern Europe is most exposed to punishing temperatures, the real test for adapting to a warmer world may come in northern Europe. Streets and buildings in Mediterranean countries have been designed with heat in mind—think shutters, awnings, shaded streets, and public fountains—and there are signs that people are already reducing risk by adapting. Northern European countries such as the UK, Switzerland, and Norway will suffer the greatest relative rise in uncomfortable temperatures, according to a 2023 study.Toward a Cooler Future: Practical SolutionsIn the UK, poorly insulated homes expose people to dangerous temperatures in both winter and summer. The government's official climate advisers have recommended that air conditioning be installed in all care homes and hospitals within the next 10 years, and in all schools within 25 years. While greening cities and reducing pollution remain critical, individuals can also make a difference through simple actions: drawing blinds, drinking water, staying indoors during the hottest parts of the day, and checking on vulnerable neighbors. These interventions, doctors and scientists assure, can make a meaningful difference in saving lives during extreme heat events.

The Lead Egypt's new monorail has opened in Cairo, offering a modern and efficient way to travel, but concerns remain about its affordability for many commuters. Cairo's New Monorail Experience The monorail's 56.6km line runs between Nasr City and the New Administrative Capital, with 16 of 22 stations opened in the trial phase. Passengers have praised the monorail's cleanliness, air conditioning, and efficiency, with fares ranging from 20 to 80 Egyptian pounds ($0.38 to $1.53) per ride. Economic Impact of the Monorail The monorail project cost approximately $2.8 billion, built in partnership with Alstom, Arab Contractors, and Orascom. At full capacity, the line can carry 600,000 passengers daily and is expected to create around 20,000 jobs. Affordability Concerns Despite the monorail's benefits, concerns remain about its affordability for many commuters. Egypt's minimum wage is 8,000 pounds a month, approximately $153 at current rates. The monthly cost of riding the full line daily with a subscription reaches approximately 1,760 pounds ($33.80), around 22 percent of the minimum wage. Future Outlook Experts believe that the monorail's fares may decrease as demand increases, but for now, the system works for those who can afford it. The government hopes that the monorail will help solve Cairo's traffic problems and expand the city's transportation infrastructure.

The Need for Air Conditioning in the UK British homeowners are rapidly acquiring air conditioners as the climate crisis superheats our summers. An estimated 4m homes have an air conditioner, double the figure from three years ago. Can Air Conditioning Be Green? Because air-conditioning units use more energy than other cooling devices, this results in more carbon emissions. Using a portable unit for an average of eight hours a day during the summer would result in about 4.87kg of CO2 emissions, roughly equivalent to driving 18 miles. Options for Greener Air Conditioning One approach could be running it only when there is a high level of renewable energy on the grid – for example during the sunniest part of the day. You may choose to pre-cool rooms before the evening peak in electricity demand. Or you could power the air conditioner with a home battery that charges up during renewable energy surpluses, helping you make the most of renewables without owning them yourself. Types of Air Conditioning It’s important to note that not all air conditioners are alike. Portable versions were relatively inefficient. If you invest in built-in air conditioning, make sure you get the right size unit for the room you’ll be cooling. A wall-mounted unit powerful enough (12,000 BTU) to cool the average British bedroom costs about £750, plus £1,150 for installation. Alternative Cooling Methods Air conditioners work using the same principle as heat pumps – they move heat from one place to another with the help of a refrigerant fluid. But the devices generally referred to as “air-to-air heat pumps” are reversible and can provide heating as well as cooling. Homeowners who switched from oil or gas heating to an electric-powered air-to-air heat pump, and used it for winter heating and summer cooling, were decarbonising their homes.

The UK Heatwave Effect The UK experienced a 'tropical night' on Monday after temperatures earlier in the day had hit a provisional all-time meteorological spring record of 34.8C (94.6F) at Kew Gardens in south-west London. The record was broken again on Tuesday when temperatures provisionally reached 35C (95F) at Heathrow and Kew Gardens. Surge in Sales of Cooling Products Retailers have reported a significant surge in sales of cooling products and summer essentials. Tesco said that, compared with the previous week, sales of ice cubes had tripled during the heatwave, while sunscreen sales rose almost sixfold. A spokesperson said: 'We sold more than 30 times as many electric fans.' Sales of fans are selling at a rate of three a minute. Ice cube sales have tripled compared to the previous week. Sunscreen sales have risen almost sixfold. The Rise of Air Conditioning in UK Homes An estimated 4m homes in the UK now have air conditioning, double the figure from three years ago, as Britons complain of 'unliveable' conditions during high temperatures. Impact on Retail and Consumer Behavior Households are also swapping heavy bedding for low-tog summer duvets and installing blackout blinds to block out the sun. Ufurnish, a platform that helps users find furniture, said searches for blackout blinds last week rose by 118%, parasol searches increased by 384% and outdoor rug searches climbed 158%. Future Outlook Experts suggest the increase in ownership of cooling products and air conditioning is the result of more people working from home and rising summer temperatures. The climate crisis is making every heatwave more intense and more likely to happen.

The Grim Reality of a Heatwave-Prone Britain If you think the temperature is uncomfortable today, let me take you to the last day of July 2052, where the rays of the climbing sun reveal a city still sweltering in the residual heat of the day before. From the air, London resembles a colossal refugee camp. Streets, gardens and parks are teeming with tents and cobbled-together shelters, within which the city’s residents have spent another uncomfortable night away from the heat traps that their houses and flats have become. After six days when the temperature peaked at about 40C, another scorcher is on the way. The Consequences of Inaction Half-hearted attempts to upgrade insulation across the country’s housing stock ran out of steam and cash decades earlier, and most homes still have few barriers to the infiltrating heat. Almost all the country’s electricity is now from renewables, which has brought the cost down, but the relentless onslaught of extreme weather has driven an ever-deepening economic depression across the world. Many now have air conditioning, but can’t afford to run it. The Data Analysis: A Future of Water Rationing and Food Shortages Water rationing across the south-east of England due to a succession of dry winters and a spring drought. Failed harvests at home in the previous two years, and massively reduced food imports, leading to the rationing of bread and other staples. Every hospital is overwhelmed as the incessant heat and humidity take their toll on vulnerable people, the old and the very young. The Impact Analysis: A Nation Unprepared The UK Climate Change Committee flagged last week in its latest report to the government that our country is not built to handle such heat and its all-pervasive ramifications. More than nine in 10 homes are not well insulated enough to keep out the heat, while by 2050 there is forecast to be a daily shortfall in water supply of 5bn litres. The Prediction: A Future of Increased Hardship Bearing in mind that we continue to pump out CO2 equivalent to the weight of 800,000 Titanics every year, and fossil fuel corporations are actively planning to expand operations, it is practically impossible for emissions reductions to happen fast enough to reduce the rate at which our world is heating. Consequently, 40C-plus mid-century heat in the UK is now baked in. We need, then, to face the fact that life in the 2050s is going to be very different from today, and act now.

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 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.
