The World Health Organization (WHO) has warned that Europe remains insufficiently prepared to cope with increasingly frequent and intense heatwaves, despite years of scientific evidence linking rising temperatures to serious health risks. As another spell of exceptionally hot weather approaches parts of the continent, health officials have urged governments to strengthen emergency planning, improve healthcare resilience and protect vulnerable communities from the growing dangers posed by extreme heat. The warning comes after weeks of record-breaking temperatures across several European countries that have already placed significant pressure on hospitals, transport networks and emergency services.
Why Is the WHO Warning Europe About Extreme Heat?
The WHO says Europe is warming at a faster rate than the global average, increasing both the likelihood and severity of prolonged heatwaves. According to the organisation, extreme heat should no longer be viewed as an isolated weather event but as a major public health challenge requiring long-term planning and investment.
Regional officials have stressed that many countries continue to respond reactively rather than proactively. While some governments have introduced heat-health action plans, experts argue that preparedness remains uneven, particularly when healthcare systems face simultaneous pressures from ageing populations and increasingly frequent climate-related emergencies.
What Did WHO Officials Say About Europe’s Preparedness?
WHO Regional Director for Europe Hans Kluge has called on governments to recognise extreme heat as a public health crisis rather than simply a seasonal inconvenience. He urged authorities to ensure hospitals have sufficient capacity, safeguard high-risk patients, secure reliable cooling systems, maintain emergency power supplies and support frontline healthcare workers before temperatures peak.
WHO Director-General Tedros Adhanom Ghebreyesus has similarly warned that climate-resilient healthcare systems must become a policy priority. He said delaying investment would leave populations increasingly exposed as heatwaves become more frequent under changing climate conditions.
How Have Recent Heatwaves Affected Europe?
Recent weeks have brought exceptionally high temperatures across much of southern and western Europe, with several countries recording temperatures above 40°C. The heat has disrupted transport services, forced school closures, damaged infrastructure and contributed to increased demand on emergency medical services.
Healthcare providers in several countries have reported sharp rises in patients suffering from heatstroke, dehydration and other heat-related illnesses. In France, emergency departments have experienced substantial increases in admissions linked to extreme temperatures, while ambulance services elsewhere have also reported unusually high call volumes during recent hot weather.
Why Are Health Experts Concerned About Future Summers?
Scientists increasingly believe that Europe’s recent extreme temperatures are not isolated incidents but part of a longer-term trend associated with climate change. Research indicates that rising global temperatures are increasing both the frequency and intensity of heatwaves, making adaptation measures more urgent.
The WHO has described the current period as a warning of what future summers may bring unless governments accelerate adaptation efforts. Experts argue that infrastructure originally designed for cooler climates is becoming less suitable as prolonged periods of intense heat become more common.
Which Groups Face the Greatest Risks During Heatwaves?
Older adults, infants, pregnant women and people living with chronic illnesses remain among those most vulnerable to extreme heat. Individuals with cardiovascular or respiratory conditions face heightened risks, while outdoor workers and those without access to adequate cooling may also experience significant health impacts.
Urban residents can be particularly exposed because densely built environments retain heat through the “urban heat island” effect. Limited green space, extensive concrete surfaces and inadequate ventilation can cause city temperatures to remain dangerously high even overnight, reducing opportunities for recovery during prolonged hot spells.
How Are Governments Responding to the Challenge?
Several European governments have introduced emergency heat alerts, public health campaigns and cooling centres aimed at protecting vulnerable residents. Some cities have expanded access to shaded public spaces, increased tree planting and invested in urban cooling projects to reduce local temperatures.
However, health experts argue that broader structural changes remain necessary. These include improving building insulation for both winter and summer conditions, modernising hospitals, upgrading transport infrastructure and integrating climate resilience into long-term public planning.
Questions also continue over the role of air conditioning in Europe. While demand has increased during recent heatwaves, policymakers continue to debate how to balance public health needs with energy efficiency and climate objectives.
What Does This Mean for the United Kingdom?
Although much of the recent attention has focused on continental Europe, the United Kingdom has also experienced increasingly frequent periods of extreme heat. Recent hot weather has affected hospitals, transport services and public health, with surveys suggesting many households struggled to keep homes cool and experienced disrupted sleep during the latest heatwave.
Public health authorities continue to encourage people to stay hydrated, avoid strenuous outdoor activity during the hottest parts of the day and regularly check on elderly relatives and neighbours during periods of extreme temperatures.
