Over two thousand individuals lost their lives across Europe due to the intense June heatwave.
A rapid study conducted by scientists from Imperial College London, the Royal College of London, and the London School of Hygiene and Tropical Medicine has revealed that climate change significantly contributes to heat-related deaths in Europe, particularly during extreme heatwaves. The recent European heatwave in June 2025, which lasted from June 22 to July 2, serves as a stark reminder of this impact.
## Key Findings
The study found that human-caused climate change has made heatwaves up to 4°C hotter in Europe. This warming effect is attributed to the rise in global temperatures, which have increased by about 1.3°C above pre-industrial levels. During the heatwave in question, an estimated 1,500 people across 12 European cities were killed by climate change, with the true death toll potentially stretching into the tens of thousands across the entire continent.
Researchers used rapid analysis to estimate the impact of climate change. They compared historical weather data to actual temperatures during the heatwave, using well-established models to calculate excess heat-related deaths.
## Impact of Climate Change
The study highlights that climate change not only increases the frequency of heatwaves but also intensifies their severity. This results in more heat-related deaths than would occur without the warming effect. The increased death toll underscores the urgent need for climate mitigation strategies to reduce greenhouse gas emissions and prevent further intensification of heatwaves.
The extreme heat led to the outbreak of fires in Spain and France, further emphasizing the destructive potential of climate change-induced heatwaves. It is important to note that much of Western Europe suffered from 40-degree heat during this period.
Dr. Ben Clark, one of the researchers involved in the study, stated that the trend of heat-related deaths is much more dangerous due to climate change. He emphasized that most deaths caused by high temperatures are not officially recorded, suggesting that the true impact of these heatwaves may be even more devastating than the numbers indicate.
The study covered data from 12 European cities, including Barcelona, Madrid, London, and Milan. However, it did not mention any other cities or regions outside of these 12 European cities analyzed. The study did not discuss any forecasts for future heat waves or climate conditions, nor did it discuss the role of thunderstorms or fires in the heat-related deaths. It also did not cover data beyond the 10-day period mentioned earlier.
As the world grapples with the reality of climate change, it is crucial to understand its impact on human health and wellbeing. The findings of this study serve as a grim reminder of the urgent need for action to mitigate the effects of climate change and protect our communities from the devastating consequences of extreme heatwaves.

Science has drawn a connection between climate change and heat-related deaths, with the study showing that human-induced climate change makes heatwaves up to 4°C hotter in Europe. In the health-and-wellness field, this increased heat can lead to significant devastation, as evidenced by the estimated 1,500 deaths across 12 European cities during a 2025 heatwave. Future research in environmental science is essential to better understand and mitigate the impact of climate change on our environment and health.
