WHO Warns Europe of Deadly Heatwave Amid Fires and Infrastructure Gaps

The World Health Organization (WHO) has issued a severe warning to European countries as a new, intense heatwave develops over the Atlantic Ocean, threatening what WHO officials call the "deadliest weeks" of the summer. This heatwave follows a record-breaking June that caused thousands of deaths and exposed critical gaps in Europe’s preparedness for climate-related health impacts. Meteorologists predict temperatures will soar to 43 degrees Celsius in Portugal and southern Spain in the coming days, with the heatwave expected to spread to France and the Benelux countries (Belgium, Netherlands, Luxembourg) later in the week.

Southern Europe is currently battling massive wildfires fueled by dry vegetation, strong winds, and relentless heat, while central and southern Italy face thunderstorms that will not alleviate the heat stress. WHO’s Regional Director for Europe, Hans Kluge, convened an urgent video meeting with representatives from 41 countries, the European Commission, and civil society organizations to review lessons from the recent heatwave. Kluge highlighted a worrying lack of systemic readiness, noting that fewer than half of European countries have national emergency plans to address heatwave health effects. Such plans are crucial for defining responsibilities, identifying vulnerable populations, and triggering automatic emergency responses when temperatures exceed critical thresholds.

The urgency of WHO’s warning is underscored by the previous heatwave from June 20 to 28, described as Europe’s most powerful early-season heatwave ever recorded. It caused severe disruptions to energy production, infrastructure damage, and overwhelmed healthcare systems, with preliminary data indicating over 4,000 deaths in Western Europe alone, including approximately 3,700 in France, the Netherlands, and Belgium. Concurrently, vast wildfires have forced tens of thousands of residents in Spain’s Catalonia region into home lockdowns and prompted preventive evacuations in Andalusia. In France, thick smoke from fires near Perpignan temporarily closed a local airport, and organizers of major international sporting events like the Tour de France are closely monitoring conditions to ensure safety.

Europe’s vulnerability is compounded by its rapid warming rate, which is double the global average. Historically, European infrastructure was designed to retain heat during winter rather than dissipate it in summer, resulting in a severe shortage of air conditioning. Only one in five European households has air conditioning, compared to about 90 percent in countries like the United States and Japan. The shift from viewing air conditioning as a luxury to a necessity for workplace safety and public health is sparking heated political debates ahead of upcoming elections. Economists warn that without significant structural adaptation, rising summer temperatures could reduce labor productivity by over 10 percent in vulnerable sectors such as agriculture and construction by mid-century.

Despite long-term forecasts, European governments remain focused on short-term survival. WHO urges immediate implementation of temporary protective measures for vulnerable groups, including nursing home residents, the homeless, and isolated elderly individuals, who currently lack consistent emergency support. Countries are called upon to replicate successful models like Italy’s real-time mortality monitoring and Spain’s public communication strategies before the current heatwave reaches its peak intensity.
