Extreme temperatures, primarily heat, are projected to result in as many as 2.3 million deaths in Europe by the end of the century if countries fail to significantly reduce carbon emissions and enhance adaptation strategies, according to a recent study by the London School of Hygiene and Tropical Medicine. The findings highlight a concerning trend where the number of heat-related fatalities is expected to surge, while cold-related deaths will decline more gradually.

Currently, cold temperatures account for more deaths in Europe than heat, but this dynamic is shifting as global warming continues. The study simulated various climate scenarios and examined mortality rates across 854 cities, establishing that without effective climate action, regions such as Italy, southern Spain, and Greece will face steep increases in heat deaths. In contrast, parts of Scandinavia and the UK may experience a decline in temperature-related deaths largely due to milder winter temperatures, as reported in Time.

Even under the most favorable conditions—where carbon dioxide emissions from fossil fuels are significantly curtailed—research lead author Pierre Masselot, an environmental epidemiologist, stresses that the net result will still indicate an increase in heat-related fatalities. "The Mediterranean is a so-called climate hotspot," he noted, "warming much quicker than the rest of the world, with Malta projected to experience an increase of 269 deaths per 100,000 people by the century's end," as further elaborated in a report by HuffPost.

The study outlines that cities like Barcelona could see nearly a quarter of a million additional temperature-related deaths, with Rome and Naples nearing 150,000 each. In scenarios predicting a slight worsening of current pollution trends, there could be an alarming 5.8 million excess heat deaths attributed to climate change, highlighting a stark contrast with nearly 3.5 million fewer cold deaths.

As the research highlighted, the environmental challenges faced by older housing structures in Europe and the limited availability of air conditioning necessitate significant adaptation measures. Masselot emphasizes the need for increased air conditioning, green spaces, and community cooling centers to mitigate the projected rise in temperatures, particularly in vulnerable populations, who are at higher risk due to the region's aging demographics, as noted by AP News.

Dr. Courtney Howard, a Canadian emergency room physician, remarked on the severity of heat, stating, "Temperatures in places like Rome — reaching up into the 40s (104-122 degrees Fahrenheit) — represent serious heat stress conditions that are particularly dangerous for older adults lacking air conditioning."

The projections serve as a stark reminder of the urgent need for comprehensive climate policies, enhanced urban infrastructure, and community preparedness to tackle the impending health crisis posed by extreme heat in Europe.
