A new study published in Nature Medicine has raised alarming predictions regarding the future health impact of heatwaves in European cities, with Athens expected to face nearly 90,000 extra heat-related deaths by the end of the century due to rising temperatures.
The research, which examined temperature and mortality data from 854 urban centres across 30 European countries, highlights a stark reality: even under the most optimistic climate change scenarios, heat-related deaths will dramatically increase in European cities, particularly in the Mediterranean region.
In 2022, Europe experienced one of its deadliest summers, with an estimated 70,000 people losing their lives to extreme heat. The new study indicates that heat-related fatalities are set to surpass cold-related deaths by 2100, reversing the current situation where cold deaths outnumber heat-related fatalities by a factor of 10.
The study analyses three different climate change scenarios, factoring in strategies such as increasing green spaces and expanding air conditioning in urban areas. Despite these potential adaptations, the models predict that, even with substantial mitigation measures, mortality rates will continue to rise in all scenarios, with a projected increase of 2.4 million heat-related deaths across Europe by the century’s end.
For Athens, this translates to a dire forecast of nearly 90,000 extra deaths from heatwaves, with Mediterranean cities bearing the brunt of the impact. In comparison, Barcelona is projected to suffer the highest toll with 246,000 deaths, followed by Rome (148,000), Naples (147,000), Madrid (130,000), and Milan (110,000).
Although the study did not include rural areas, it is expected that heat-related deaths will also rise in these regions, albeit to a lesser extent, due to the absence of the heat island effect seen in urban centers. Moreover, the study acknowledges that the findings could underestimate the toll, as the analysis focused on average daily temperatures, not accounting for extreme night temperatures or humidity, which can exacerbate the risk.
While the research models carry a degree of uncertainty, the findings strongly challenge the notion that climate change might bring “beneficial effects” through a reduction in cold-related deaths. As temperatures continue to climb, the study underscores the urgent need for cities to adapt and prepare for a future where life in urban areas could become increasingly uninhabitable.
As the Mediterranean faces the brunt of climate change, experts are calling for immediate action to safeguard public health and invest in infrastructure that can help cities cope with the intensifying heat. The report serves as a stark reminder of the pressing need for comprehensive climate policies to mitigate the health risks posed by rising temperatures.
