Europe faced its worst record in terms of death from heat to climate change responsible for two-thirds.
Europe’s burning wine is estimated to have claimed more than 50,000 lives in urban areas, making it the worst ever recorded, according to a new report.
Researchers are clear on the cause: Climate change was largely due to fossil fuels burning, and about two thirds of these deaths from excessive heat.
The figure far exceeds the previous higher figure of around 29,000 deaths in the summer of 2022 and 28,000 in 2003 across the modeled area.
It is a testimony to the extreme heat facing the continent that is warming faster in the world between June and August of this year. A series of heat waves saw temperatures in Western Europe rise by 2.9 °C above the average in 1991-2020, even increasing to 12 °C in several days often hitting countries that are neither accustomed nor prepared for such temperatures.
These figures are a strong reminder that our hottest and more extreme summers are having an increasingly serious impact on public health, says study coauthor Dr. Clair Barnes, an extreme weather researcher and climate change in Imperial College London.
After these statistics, there are real people whose lives have been lost and real families who mourn about them. )
Almost a third of the estimated deaths occurred during the particularly strong heat wave between June 17th and July 1st, when temperatures averaged 5.3 °C above the rate.
How were deaths appreciated by summer heat?
The study used the modeling to assess the number of excessive summer-related deaths dating back to the beginning of the century.
The true burden of mortality, in fact, due to heat is not directly seen or measured, says study coauthor Dr. Malcolm Mistry, assistant professor in climate and geospace design at the London School of Hygiene and Tropical Medicine ( INSM).
Therefore, heat is often called a silent killer, with the death toll reported less in some regions on a global level. )
Scientists used temperature data and design based on the historical relationship between heat and mortality to assess the number of victims in the summer of 2026. They considered geographical and environmental characteristics, socioeconomic factors, availability of health services, and specific age links between temperature and mortality.
The model was applied in 854 urban areas across the EU, the United Kingdom, Norway and Switzerland, which make up about 40 per cent of the population of 30 countries surveyed.
A separate atrium study covering the summers of 2000 to 2025 was used by comparison, with results for the years that resulted generally in accordance with official statistics published by national health authorities. Many European countries have not yet published final figures for the summer of 2026.
Researchers then compared current temperatures to those expected without warming from climate change to assess the additional deaths caused.
In general, 65 percent of overcrowding deaths, or about 32,000, in the summer of 2026 were attributed to climate change caused by man. Earlier in the century, it was estimated that this was responsible for about 40 per cent of heat related deaths.
It is another reminder both of the necessity of implementing targeted interventions to protect those who are more vulnerable to this increasingly extreme heat and of the growing need to flee quickly from fossil fuels to slow down the pace of change and limit future heating, says Dr. Barnes.
Who is most vulnerable to extreme heat?
The vulnerable people are more exposed to the dangers of extreme heat, including those suffering from disease; the elderly or many young people; and those who are unable to leave the heat for physical or socioeconomic reasons.
In the summer study of 2026, people aged 85 and older made up about half the estimated deaths. But even younger adults were affected: there were about 800 additional deaths among people between the ages of 20 and 44, and a total of about 6,000 people under the age of 65.
Researchers also found geographical changes, with southern Europe evidently experiencing more deaths related to high temperatures than North Europe.
This is largely due to the higher temperatures facing the most south, although other weaknesses came into play.
For example, factors such as increasing air pollution levels, limited infrastructure of green spaces, access to health systems, and heat alarms, explains coauthor of the study, Dr. Garyfalos Konstantinoudis, assistant professor at the Grantham Institute of IL.
Europe’s unprecedented wine: Which place was worst hit?
The dangers to Europe’s hot summer public health were remarkable, with some governments warning of heat and real-time mortality estimates related to heat.
According to the 2026 summer report, Italy is estimated to have suffered the highest deaths related to heat – a total of 13,303. Next was France with 7,268, followed by Spain with 6,824.
The traditionally colder countries also faced difficulties in the heat, which became more dangerous by infrastructure designed for a different climate, and citizens without such temperatures.
In the United Kingdom, summer is historically the quietest time for our health service. However, this summer there was demand and pressure similar to a very bad winter virus season, says Andrew Hartle, professor of Anesthesia Practice at Imperial College Healthcare, Euronews.
The accuracy of molding means that it has the potential to allow health services to prepare for extreme events before they happen.
In addition to reducing greenhouse gas emissions to limit future warming, cities can invest in increased green-blu spaces, which come with the benefits of lowering temperatures and improving air quality.
The authors of the study say that Northern and Western Europe should look south for solutions that are already well established.
These include investing in climate shelters; reconstruction of buildings to cope better with heat, such as increasing curtains or outer bars; and promoting behavioral changes, such as control of vulnerable neighbours, failure in the midday sun, taking heat warnings seriously, seeking shade and drinking too much water
