On Monday 26 May 2026 the United Kingdom experienced a “tropical night” as minimum temperatures stayed above 20 °C, breaking the May daily‑minimum record for the second day in a row.Record‑Breaking Night Temperatures Across the UKKenley airfield (south London) recorded a minimum of 21.3 °C, the highest May night ever.Kew Gardens (south‑west London) hit 34.8 °C, setting a provisional all‑time hottest spring temperature.Previous May night record was 19.4 °C at Kenley on the preceding Sunday.12 locations, from Suffolk to Berkshire, broke their local records on Monday.97 Met Office monitoring sites reached or exceeded 30 °C.Numbers That Define the HeatwaveHighs of up to 35 °C forecast for southern England and Wales on Tuesday, with some areas approaching 36 °C.Heat‑wave threshold for this time of year is 28 °C (London and northwards to Cambridgeshire).Eight parts of England already met the three‑day heat‑wave criteria by Sunday evening, including Heathrow, Kew Gardens, Northolt, and sites in Oxfordshire, Suffolk and Essex.Implications for Climate Resilience and Public SafetyMet Office senior forecaster Greg Dewhurst warned that heatwaves are now developing “so quickly” due to the climate crisis.Firefighters battled a grass fire near Arthur’s Seat in Edinburgh as temperatures hit 25 °C.A 13‑year‑old boy died after drowning in a West Yorkshire reservoir amid the heat.Nearly 100 sites surpassing 30 °C underscores how many locations are meeting heat‑wave thresholds.What the Forecast Holds for the Rest of the SummerTemperatures are expected to gradually decline from mid‑week but remain in the high 20s with dry, sunny spells.Potential thunderstorms on Tuesday could temporarily curb peak temperatures.Continued high night‑time minima suggest that further “tropical nights” are likely as the season progresses.

The Heatwave in Western Europe Seven people have died in France in an extreme early-summer heat event that is affecting a swathe of western Europe, as France and the UK set record highs for May and temperatures were forecast to rise further on Tuesday. Record Temperatures and Deaths "What I can say today is that there have been seven deaths linked directly or indirectly to the heat," a French government spokesperson, Maud Bregeon, told TF1 television, adding that five of the deaths were by drowning. Météo France, the national weather agency, said Monday's highest reading, 37.1C, was recorded near Hossegor, in the south-western department of Les Landes, and that temperatures across the west of the country could exceed 36C on Tuesday. The Data Analysis The UK's Met Office said Monday was the country's hottest May day on record, with temperatures hitting 34.8C at Kew Gardens, south-west London, a reading it described as "exceptional in the UK even in mid-summer, let alone May". In Spain, widespread highs of 36-38C in the Guadiana, Guadalquivir and Ebro valleys were expected to continue possibly until Friday, the state weather service, Aemet, said, adding that "in some of those areas, temperatures could reach 40C". The Impact Analysis In Italy's Lazio region, which includes Rome, authorities have imposed restrictions on work in conditions "with prolonged exposure in the sun", for example on farms, construction sites and in the delivery sector, between 12.30pm and 4pm. Eight of France's 96 administrative departments have been placed on an orange high-temperature alert, the second-highest level, requiring the population to "be vigilant and take precautions", with a further 20 on a more moderate yellow warning. The Prediction Christophe Cassou, a climate scientist, told Le Monde: "This is an unprecedented event with a one in 1,000 chance of happening at this time of year in the climate of 1979 to 2025." He added that "it would have been virtually impossible in the pre-industrial era". The prime minister, Sébastien Lecornu, called a meeting of key ministers on Thursday to assess government preparations for heatwaves after more than 350 weather stations across France recorded new monthly highs on Monday.

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.

Unprecedented May Heatwave Forecast for EnglandTemperatures are expected to reach 35°C on Monday across parts of England, marking the hottest May day on record in the UK.Temperature Records Set to Shatter Historical May HighsThe Met Office says the current May record of 32.8°C will be eclipsed by a margin of 2.2°C, a jump unprecedented for the season.Previous monthly maximum record broken in January 2024 by 1.6°C.July 2022 peak of 40.3°C exceeded its prior record by 1.6°C.Quantifying the Heat: Nighttime Temperatures and Tropical NightsOvernight temperatures hit 19.4°C at Kenley, London, narrowly missing a “tropical night” (≥20°C). Two tropical nights are forecast for Monday and Tuesday.Implications for Public Health and Climate Trends in the UKHeatwave conditions now cover multiple sites including Santon Downham (Suffolk), Heathrow, Kew Gardens, and several locations in Essex and Oxfordshire. The event underscores the accelerating warming trend highlighted in the European State of the Climate report, which names Europe as the fastest‑warming continent.Outlook: Summer Heatwaves and the Emerging Super El NiñoScientists warn a “super El Niño” developing this summer could intensify heat events, with global heat records expected to be challenged by 2027.

The UK's Cooling Revolution More than 4 million homes in the UK now have air conditioning, double the figure from just three years ago, marking a significant shift in how British households cope with increasingly hot summers. Types of Cooling Systems and Their Usage Portable units with power ratings around 1kW are slightly more common than the more powerful built-in versions that can guzzle 2.7kW of power – more than an electric oven. Of the 4 million households with air conditioning, nearly 1.9 million have built-in units, while 2.2 million homes use portable air conditioning units. More than 260,000 UK households have heat pumps that can be used to cool homes. When used in cooling mode, heat pumps work like traditional air conditioning units by extracting heat from the home and releasing it outside. The Financial Impact of Cooling The energy consumption and associated costs of air conditioning are substantial. In a typical week, households use their built-in units for about four hours at a cost of £2.93. However, during heatwaves when usage increases to over nine hours daily, weekly costs soar to £42.43. Portable units, which use 1kW of power, typically cost 83p per week with three hours of usage. During hot spells, when used for more than nine hours daily, this rises to £15.71 weekly. Climate Change Drivers Experts suggest the increase in air conditioning ownership is the result of more people working from home and rising summer temperatures. Some of the UK's warmest summers have been in recent years, with the record high of 40°C set in July 2022. The government's climate advisers have warned that British homes will need air conditioning to survive predicted levels of global heating, as traditional cooling methods like drawing curtains and opening windows become insufficient. Future Projections and Recommendations The Climate Change Committee has recommended that air conditioning should be installed in all care homes and hospitals within the next 10 years, and in all schools within 25 years. Heatwaves were expected to exceed 40°C in all parts of the UK by 2050, potentially leading to an additional 10,000 heat-related deaths annually. With about nine in ten UK homes likely to overheat, the adaptation to higher temperatures is becoming increasingly urgent. However, air conditioning is energy intensive, accounting for about 4% of global greenhouse gas emissions. Sustainable Cooling Solutions Sam Alvis, head of energy security at the IPPR thinktank, called for more solar panels on roofs alongside air conditioning installations. "We are going to have to get used to being a hot country, which is quite a mindset shift for the UK," he said. "Air conditioning is actually a great pair for solar from an energy system point of view because it matches supply and demand." More efficient modern systems using heat pumps, which are already subsidized by the government to replace gas boilers, could provide a more sustainable cooling solution, though these are rarely installed at present.

The latest analysis by Cancer Research UK reveals that melanoma, the most serious form of skin cancer, hit a historic high in the United Kingdom last year, with 20,980 diagnoses in 2022. Experts warn that without stronger prevention measures, annual cases could climb to 26,500 by 2040, coinciding with hotter summers and an ageing demographic. Record Melanoma Diagnoses in 2022 For the first time, UK melanoma cases have exceeded the 20,000 mark. The surge reflects broader trends in skin‑cancer incidence and underscores the urgency of public‑health interventions. Projected Growth to 26,500 Cases by 2040 Forecasted annual cases for 2040: 26,500 Increase of 23% among men Increase of 26% among women Drivers: ageing population, higher UV exposure, and lifestyle factors Public Health Implications Amid Heatwave Alerts Heat health alerts have been issued for the upcoming bank‑holiday weekend, with temperatures expected to reach up to 30°C in parts of England. Elevated UV levels amplify the risk of sunburn and, consequently, melanoma development, especially for vulnerable groups. Preventive Strategies and Policy Recommendations Key voices—including Michelle Mitchell, CEO of Cancer Research UK, and Prof Peter Johnson, NHS England’s national clinical director for cancer—stress the importance of: Seeking shade during peak sun hours Wearing protective clothing, hats, and sunglasses Applying broad‑spectrum sunscreen with at least SPF 30 and reapplying regularly Promptly consulting a GP about new or changing moles, sores, or skin patches Outlook for Sun Safety and Cancer Prevention If the public adopts these preventive measures, the rise in melanoma cases could be mitigated despite demographic pressures and hotter summers. Ongoing education, stronger sunscreen regulations, and targeted campaigns during heatwaves are likely to shape the trajectory of skin‑cancer incidence in the UK over the next two decades.

The Lead: One Nation's Standalone Climate Denial As the populist right-wing One Nation party gains momentum in Australian polls, it maintains a firm stance against decades of climate science evidence showing the planet and Australia are warming. The party claims to be the only political force in Australia questioning climate science, but experts say this position is not only scientifically baseless but increasingly out of step with global trends in climate misinformation. The Event Details: One Nation's Climate Contradictions One Nation's position on climate change is rooted in denial and conspiracy theories, despite overwhelming scientific evidence. The party's energy and climate policies have previously been literal cut-and-pastes from the now-defunct climate denial group the Galileo Movement. Currently, One Nation rejects the scientific consensus that the planet and Australia are warming, claiming extreme weather was more prevalent before 1960—a position climate scientists have compared to believing the Earth is flat. The party also wants Australia to leave the Paris Agreement and would push to close down the federal climate change department "and all related agencies, regulations and programs." They proudly declare: "We are the only political party to question climate science." The Data Analysis: Australia's Unequivocal Warming Trend Despite One Nation's claims, Australia has experienced significant warming since 1910. The Bureau of Meteorology's official long-term climate dataset shows Australia has warmed by 1.5°C since 1910. Temperature readings before this period are not included in the official dataset because they were often taken with non-standardized equipment, making them less reliable. Research into pre-1910 temperature records shows temperatures from 1860 to 1909 were similar to those from 1910 to 1959. Since 1960, both maximum and minimum temperatures have risen significantly. The independent Berkeley Earth group's analysis of historical temperature data confirms Australia has warmed substantially since the 1880s. One Nation points to a single weather station in Newcastle (Nobby's) to claim no pattern of warming exists—a classic example of cherry-picking data while ignoring the broader evidence showing temperatures are warming across Australia. The Impact Analysis: Political Consequences of Climate Denial One Nation's climate denial positions have significant political implications in Australia. Research from CSIRO a decade ago suggested that views on climate change can be influenced by how a person votes, rather than the other way around. This means votes for One Nation could lead more people to reject established climate science. Dr. John Cook, an expert on climate science denial, notes that One Nation is "not only out of touch with the scientific evidence, they're even out of touch with the rest of the climate denial community." Over the past decade, climate misinformation has transitioned from science denial to attacking climate solutions, as the scientific evidence for human-caused global warming has become undeniable. Prof. Sarah Perkins-Kirkpatrick, a climate scientist at Australian National University, emphasizes: "There's a wealth of evidence that extreme heat events are increasing worldwide since the 1950s. We see increased intensity of droughts and heatwaves and the intensity of tropical cyclones is increasing." The Prediction: Future of Climate Politics in Australia As climate impacts worsen in Australia—with more frequent and intense heatwaves, bushfires, and extreme weather events—One Nation's climate denial stance may become increasingly untenable politically. The party's net zero conspiracies, including claims that climate action is part of a plot to create a "socialist Australia," are based on misinformation and misrepresentations of statements by figures like former World Economic Forum chair Klaus Schwab. One Nation's assertions that renewable energy is causing electricity price increases are also contradicted by experts. Research from CSIRO suggests that if 82% of Australia's electricity came from renewables backed by storage, the cost of generation would be a third less than current prices. The real drivers of rising electricity costs are aging infrastructure and rising international gas prices, not the transition to renewables. As Australia faces increasing climate impacts, political parties that reject established climate science may find themselves increasingly isolated, both scientifically and politically. The future of Australian climate politics may depend on how mainstream parties respond to One Nation's misinformation and whether they can effectively communicate the scientific consensus on climate change.
