Extreme heat tightening its grip on Europe
The unprecedented heat dome currently over Europe serves as a critical reminder that extreme heat remains the continent's most fatal climate-driven health hazard. This is the second early-summer heatwave of the year and underscores the vulnerability of our expanding urban heat islands and the disproportionate risks faced by our most vulnerable citizens, from infants to the elderly.
At this critical moment, the launch of the new WHO Heat–Health Action Plans Guidance provides a timely and practical roadmap for action. It equips countries with concrete tools to anticipate and respond to extreme heat - through early warning systems, targeted protection of at-risk populations, stronger health system preparedness and effective communication. The message is clear: while heat is a growing threat, its impacts can be significantly reduced through coordinated, well-designed policies and interventions.
The same urgency shaped discussions at the 11th Observatory Partners Meeting on 9-10 June, hosted by the ECDC in Stockholm, where heat was highlighted as a central challenge for Europe’s resilience. This concern also resonates with the EEA’s recent publications on climate resilience, which shows how extreme weather and uneven adaptation are testing Europe’s preparedness. Partners underlined the need for stronger collaboration, more actionable data and a sharper focus on implementation where it matters most - in cities, healthcare facilities, workplaces and communities.
In this landscape, the Observatory continues to play a vital role: turning knowledge into action by connecting science, policy and practice. As heatwaves become the “new normal,” this collective effort will be essential to protect health and build a more climate-resilient Europe.
