Dr Mark Harber, special adviser on healthcare sustainability and climate change at the Royal College of Physicians, has warned that the UK is set for another record-breaking heatwave with little change in preparedness since last summer. The UK Health Security Agency issued a rare red heat alert in parts of England, signalling a serious threat to lives. This is only the second such alert; the first, in 2022, coincided with five extreme heat waves causing an estimated 2,985 excess deaths in England alone.
NHS data shows 53% surge in overheating incidents
NHS England data reveals a 53% increase in overheating incidents between 2016-17 and 2023-24, evidencing a significant spike in demand for healthcare, especially among the very young, elderly, and those with chronic conditions. For staff, stifling conditions exacerbate burnout, drive fatigue, and increase the risk of errors as pressure on services peaks. Dr Harber calls this a patient-safety crisis and a matter of national urgency, stating: 'Investing in building upgrades, workforce preparedness and proper resilience planning is no longer optional. It is essential if the NHS is to continue functioning.'
Schools closing in heatwave sparks debate
Retired teacher Sarah James criticises the closure of schools during the heatwave, arguing that sending children home to cramped, overheated homes without outdoor space is not sensible. She suggests suspending normal activities, allowing parents to take children home if possible, and treating the situation as a national emergency to ensure all children are properly cared for during the climate emergency.
Decades of warnings ignored
Linda Rabben of Baltimore, Maryland, recalls attending a UN Preparatory Commission meeting over 30 years ago where climate scientists warned of a 20-year window to solve the biggest environmental problem in 10,000 years. She also heard Indigenous leader Davi Yanomami warn of ecological catastrophe at the Rio Earth summit. She laments that humanity is still denying and temporising, asking: 'What will it take to make human beings face reality and do something about it?'
London's vulnerability exposed by heatwave
Fernando Quintana Marrero of London notes that the city remains poorly prepared for severe heatwaves, with rail services slowed, transport networks struggling, and workplaces expecting normal operations. He highlights that the success of air-quality policies, which reduced deaths linked to London air pollution by 40%, shows governments can act decisively. He urges the same determination to adapt cities to a changing climate, including investing in resilient transport infrastructure, urban cooling, green spaces, and worker protections. He concludes: 'The lesson from London’s clean-air success is simple: political will matters.'
