More than 2,700 deaths across England and Wales have been linked to unprecedented heatwaves in May and June, according to a study published on Monday. Researchers from Imperial College London, the Met Office, and the London School of Hygiene and Tropical Medicine estimated that 550 heat-related deaths occurred between May 21 and 29, while nearly 2,200 people died from June 18 to 28.
Key Details
The report highlighted that May saw temperatures reach 35.1°C (95.2°F), and June recorded highs of 37.7°C (99.9°F). Mark McCarthy, science manager at the Met Office's climate attribution team, noted,
They were extreme heatwaves for the UK, and for all parts of Western Europe, and they’re particularly exceptional for the timing and how early in the year they occurred.
The UK Health Security Agency (UKHSA) is expected to publish its official estimate of heat-related deaths in the coming weeks, based on recent death records.
Background
The study emphasized the role of climate change in increasing the intensity and frequency of heatwaves, estimating that maximum daytime temperatures were up to 4°C (7.2°F) higher than they would have been without global warming. The Climate Change Committee warned last year that the UK is "not ready" to deal with the consequences of climate change, indicating a need for improved preparedness and response strategies.

The rising frequency of heatwaves could lead to increased healthcare costs and strain on public services, particularly in the health sector. Investors will watch for the UK Health Security Agency's upcoming report on heat-related deaths, expected in the coming weeks, which may influence public policy and climate adaptation strategies.
