AI Insight
Europe is the fastest-warming continent, with temperatures rising at more than twice the global average rate since the mid-1990s, producing measurable and increasingly attributable health consequences. Approximately 70% of the roughly 24,000 summer heat-related deaths recorded across 854 European cities in 2025 have been attributed to human-induced climate change. Additionally, climate change is driving the northward expansion of Aedes albopictus, the mosquito vector for dengue and chikungunya, exposing an estimated 5 million additional people to infection risk each year.
Why it matters
These findings underscore an urgent need for integrated climate and public health policy across Europe, as rising temperatures and shifting disease vectors are already translating into preventable deaths and expanding infectious disease burdens. Accelerating coordinated mitigation and adaptation strategies at the continental level has direct implications for healthcare system preparedness and population resilience.
The pace of climate change has increased worldwide in the past decade.1 Europe is the fastest-heating continent, with temperatures increasing at more than twice the global average rate since the mid-1990s.2 It is increasingly possible to attribute health impacts to human-induced climate change. For example, nearly 70% of the approximately 24 000 summer heat-related deaths in 2025 in 854 European cities were attributed to climate change.3 Climate change is driving the rapid northward expansion of Aedes albopictus, the vector mosquito for dengue and chikungunya, increasing the population at risk of infection in Europe by nearly 5 million people annually.
