The health of millions across Europe is under intensifying threat from climate change, with political and public engagement dangerously lagging behind the scientific evidence, according to the 2026 Lancet Countdown on Health and Climate Change in Europe report. Released this week, the comprehensive analysis warns that the continent's progress is fragile and that the window for decisive, health-centred action is rapidly narrowing.
Escalating Health Impacts Across the Continent
The report documents a stark increase in both direct and indirect health consequences. Nearly every European region monitored saw a rise in heat-attributable deaths between 2015-2024 compared to the 1991–2000 baseline. The frequency of extreme heat warnings surged by 318% over the same period. Beyond mortality, rising temperatures are driving higher rates of heat-related illness, severe sleep disruption, worsening of chronic conditions, and adverse pregnancy outcomes.
Poor air quality, exacerbated by climate factors, continues to be linked to a rise in respiratory and cardiovascular diseases. Indirectly, climate change is undermining food security. The report estimates that over one million additional people in Europe faced moderate or severe food insecurity in 2023 compared to the 1981-2010 average, a trend driven by higher temperatures and widespread drought affecting agricultural yields from the Iberian Peninsula to the Danube basin.
Perhaps most alarmingly, the changing climate is facilitating the spread of infectious diseases once considered rare in Europe. Warming temperatures are expanding the habitats for disease-carrying mosquitoes. The overall average risk of dengue outbreaks has increased by 297% since 1980–2010, nearly quadrupling in the last decade alone. Cases of West Nile, Chikungunya, and Zika virus are also becoming more frequent across southern and central Europe.
“Rising heat, worsening household air pollution, exposure to infectious diseases, and growing threats to food security are placing millions of people at risk today – not in a distant future,” said Professor Joacim Rocklöv, co-director of the Lancet Countdown Europe at the University of Heidelberg. “The choices we make now will decide whether these health impacts worsen quickly or whether we begin moving towards a safer, fairer, and more resilient Europe.”
A Dangerous Disconnect in Political and Public Discourse
The report identifies a critical gap between the scale of the threat and the societal response. Public awareness appears fragmented; while health is a top concern for citizens, it is rarely connected to climate change as a root cause. This disconnect is mirrored starkly in political arenas. An analysis of 4,477 speeches delivered in the European Parliament in 2024 found that only 21 addressed the link between climate and health. The climate-health intersection is similarly absent from most party communications and social media strategies across member states.
This failure to connect the dots threatens to stall vital policy progress. The authors warn that the alarming evidence is not translating into sufficient political momentum, even as the broader geopolitical landscape creates further energy and economic pressures. The report notes, however, that proven solutions exist. Investments in clean energy, which improve air quality and health, demonstrate that effective action is feasible.
“Redirecting investments from fossil fuels into clean energy, improving air quality, safeguarding vulnerable groups and preparing health systems for rising climate shocks will deliver immediate and long‑term health benefits,” said Professor Cathryn Tonne, co-director of the Lancet Countdown Europe at the Barcelona Institute for Global Health (ISGlobal).
The need for robust governance is underscored by ongoing challenges within the EU, such as the recent investigation into farm subsidy fraud in Greece, which highlights the importance of integrity in managing the funds critical for a green transition.
The Path Forward: Health-Centred Climate Action
The Lancet report concludes that Europe retains an opportunity to reinforce its leadership on decarbonisation by pursuing rapid, coordinated policies that place health protection at their core. Such an approach would not only mitigate future climate shocks but also deliver immediate health co-benefits, reduce inequalities, and build a more resilient society.
“The window for action is narrowing, but Europe has an opportunity to reinforce its decarbonisation leadership and pursue rapid, coordinated and health‑centred climate action to protect lives, reduce inequalities and build a resilient, low‑carbon future,” Tonne stated. The urgency of coordinated international action on interconnected crises is a theme echoing beyond Europe's borders, as seen in recent diplomatic efforts to address water security in Central Asia.
The findings serve as a direct challenge to policymakers in Brussels, Berlin, Paris, Rome, and national capitals across the continent: to treat the climate crisis as the fundamental public health emergency it has become.
