Europe Faces Growing Health Risks as Heatwaves Continue

As Europe moves through the peak of its third heatwave this year, countries across the continent are dealing with the serious health consequences of record-breaking summer temperatures. Following the hottest June ever recorded, the UK Health Security Agency (UKHSA) has expanded its amber heat health alerts to cover almost all regions of England. These alerts mean that the high temperatures are likely to have a significant impact on health and social care services, as hospitals and clinics prepare for more patients suffering from heat-related illnesses.

The UK Met Office reports that these high temperatures are expected to last through much of next week. This could make the current event one of the longest-lasting heatwaves since the historic 1976 heatwave, which resulted in 250 deaths. According to the Met Office, this year has already seen eight days where temperatures went above 34C, breaking previous records from 1976 and 2020. Scientists warn that these events are becoming more common and more intense because of the ongoing climate crisis.

Friederike Otto, a professor of climate science at Imperial College London, explained that the heat we are seeing is a direct result of the 1.4C of climate change caused by burning fossil fuels. She noted that it is misleading to call this the "new normal" because the climate is not stable. As long as the world continues to burn fossil fuels, the planet will keep warming, and the definition of a "normal" summer will keep shifting toward higher temperatures. This means that even hotter heatwaves are likely in the future.

Many European nations are still dealing with the tragic results of earlier heatwaves this year. In Belgium, the public science institute described the June heat as "exceptionally deadly," reporting 1,747 excess deaths. Meanwhile, the Robert Koch Institute in Germany recorded 5,120 heat-related deaths throughout the summer. Early estimates from academic researchers suggest that the total death toll across the entire continent could be higher than 20,000 people. These figures highlight the urgent health risks posed by extreme heat, especially for the elderly and those with existing health conditions.

In response to these dangers, experts are calling for major changes to how cities are built. In France, where a nuclear power plant had to shut down due to the extreme heat, scientists have described many homes as "thermal kettles"—buildings that trap heat and become dangerously hot inside. France’s high council on climate, an independent group that evaluates government actions, has urged leaders to improve housing quality. They suggest that all new urban planning must include shaded green spaces to help cool down cities.

The council also recommended that hospitals, schools, and care homes install better cooling systems, such as ceiling fans, fixed air-conditioning units, and shutters to block out the sun. Their annual report found that France is currently not prepared for the dangerous consequences of climate change and that existing policies are not enough to prevent future risks. The authors of the report argued that the cost of doing nothing is much higher than the cost of taking action. They believe that moving away from fossil fuels is a necessary choice that would bring significant benefits to society.

As the heat continues, the focus remains on protecting the most vulnerable members of the public. The NHS in England and other health services across Europe are working to manage the increased demand for care. While immediate measures like cooling centers and public warnings are helpful, experts agree that long-term solutions are essential. Without a consolidated plan to address the root causes of climate change, the health risks associated with extreme heat will continue to grow, making the transition to cleaner energy a matter of public safety as much as environmental protection.
