Climate Breakdown Led to Half of European Heat Deaths in 2022: Study
A new study conducted by researchers at the Barcelona Institute for Global Health (ISGlobal) reveals that climate breakdown contributed to over half of the 68,000 heat-related deaths that occurred during the extreme summer of 2022 in Europe. The research underscores the urgent nature of climate change, highlighting that 38,000 lives could have been saved if human-induced greenhouse gas emissions had not exacerbated the heatwaves that swept across the continent.
The findings from the study are striking: the death toll from heat in 2022 was ten times higher than the number of homicides reported in Europe that year. Lead author Thessa Beck emphasized the immediate dangers of climate change, stating, “Many see climate change as a future concern. Yet our findings underscore that it is already a pressing issue.”
The study indicated that the effects of the extreme heat disproportionately impacted specific demographics, revealing that women, southern Europeans, and older individuals were particularly vulnerable. Researchers noted that while the connection between carbon pollution and intensified heatwaves was already established, the precise contribution to mortality rates had not been quantified until now. The study found that a staggering 56% of heat-related deaths could have been avoided if fossil fuel combustion and environmental degradation had not contributed to global warming.
This percentage represents an increase from previous estimates, which ranged between 44% and 54% six years ago. Emily Theokritoff, a researcher at Imperial College London who was not involved in the study, explained, “Even small increases in temperatures can have devastating impacts on public health. This result makes sense – heat-related death increases rapidly as temperatures push past the limits people are acclimatized to.”
The situation in Europe is particularly alarming, as the continent has been warming at twice the global rate. This accelerated warming has left hospitals and healthcare systems inadequately prepared to handle the rising number of heat-related cases. Beck cautioned that while Europe faces significant threats from extreme heat, the dangers are even more pronounced in regions like Africa, Asia, and South America. However, a lack of comprehensive data from these areas has hindered similar assessments of the health impacts of climate change.
A common misconception surrounding heat-related risks is that only extreme temperatures are dangerous. Beck clarified, “However, our study, along with previous research, shows that even moderate heat can lead to heat-related deaths, particularly among more vulnerable populations.” This revelation highlights the need for public health measures to adapt to changing climate conditions, especially in regions where populations are less acclimatized to heat.

The study’s findings call for urgent action to mitigate climate change and protect public health. The researchers emphasize the importance of reducing greenhouse gas emissions and transitioning to sustainable practices. They advocate for increased awareness and preparedness to combat the health impacts of climate change, stressing that immediate action is necessary to prevent future tragedies.
As Europe braces for future heatwaves, the findings of this study serve as a grim reminder of the interconnectedness of climate change and public health. With extreme weather events becoming more frequent, the need for proactive measures to safeguard vulnerable populations is paramount. Policymakers, health professionals, and the public must work collaboratively to address the challenges posed by climate breakdown and ensure that health systems are equipped to respond effectively to the evolving landscape of climate-related health threats.
In conclusion, the study underscores that climate change is not just a distant concern but a current reality that demands immediate attention. As Europe and the world confront the escalating consequences of climate breakdown, it is imperative to recognize the toll it takes on human lives and take decisive action to avert further tragedies. The lessons learned from the heat-related deaths in 2022 should galvanize efforts to combat climate change and protect the most vulnerable members of society from its devastating impacts.
