Extreme Heat Linked to Over 40,000 Deaths in England from 1988 to 2025

New Delhi, India Aug 26, 2026 ALN: More than 40,000 extra deaths have been attributed to extreme heat in England between 1988 and 2025, according to alarming data released by the Office for National Statistics (ONS). This figure highlights the growing toll of the climate crisis, with officials expressing concerns that this summer is on track to set new records for heat-related fatalities.

The ONS report, published on Wednesday, does not account for the current summer, during which England has been subjected to a series of intense heatwaves. The UK Health Security Agency reported on July 30 that approximately 2,877 people died during the heatwaves in May and June alone, nearly doubling the total heat-related deaths recorded for the entire summer of 2025.

Rising Risks and Vulnerabilities

The number of premature deaths due to high temperatures is expected to continue rising as climate change exacerbates heat conditions and the population ages. Vulnerable groups, including the elderly, children, and those with pre-existing health conditions, are particularly at risk.

This summer has seen emergency departments in England overwhelmed, with nearly 2.5 million patients visiting A&E each month during May, June, and July, largely due to heat-related issues. Reports from nursing unions indicate that staff have been collapsing under the strain of working in “inhumane and impossible” conditions.

Regional Disparities and Historical Context

London has recorded the highest number of deaths linked to extreme heat, with the London ambulance service responding to 25,000 more calls this summer compared to the previous year, surpassing even the peak of the Covid-19 pandemic.

Data indicates that nearly all regions in England, as well as Wales, have seen a 50% increase in the risk of death when temperatures exceed 24°C. From 1988 to 2025, over 2,000 deaths in Wales were connected to extreme heat, alongside 10,000 deaths attributed to the coldest temperatures.

Historically, cold weather has been responsible for more excess deaths than heat, with 139,000 deaths linked to the coldest days in England during the same period. However, ONS statistician James Tucker noted that the gap between heat- and cold-related deaths has narrowed in recent years, indicating a troubling trend.

Calls for Action and Preparedness

Experts are sounding alarms about the increasing risk of heat-related fatalities. Dr. Clair Barnes from Imperial College London stated, “We now face the very real prospect of heat deaths overtaking those that occur on the coldest days.” The urgency for action to mitigate emissions and improve cooling measures is becoming increasingly critical.

Bob Ward from the Grantham Research Institute emphasized that both heat- and cold-related deaths are largely preventable, labeling the situation a “shocking national scandal.” In the latest year of ONS data, heat-related deaths in England and Wales outnumbered cold-related deaths for the first time.

Government Response and Future Outlook

Emma Howard Boyd, chair of the National Heat Risk Commission, highlighted the human impact behind the statistics, urging better preparedness for vulnerable communities. The UK Prime Minister, Andy Burnham, has faced criticism for his government’s lackluster response to the ongoing climate crisis and for policies that may hinder progress, such as reducing electric vehicle sales targets.

Advisers at the Committee on Climate Change have long warned that the UK is ill-prepared for the impacts of climate change. Recommendations include installing air conditioning in all hospitals and care homes within the next decade and setting maximum temperature limits for indoor and outdoor work s.

As Europe grapples with similar heat-related challenges, the World Health Organization has reported a more than 30% increase in heat-related mortality in its European region over the past two decades. The ongoing climate crisis, exacerbated by fossil fuel consumption, is expected to lead to even more severe heatwaves in the future.

In conclusion, the data from the ONS serves as a stark reminder of the urgent need for comprehensive climate action. As the climate crisis continues to unfold, the health and safety of vulnerable populations must be prioritized to prevent further tragedies.
