Research prepared by two British organizations heat wave Registered in the period from June 23 to July 2, 2025, it may be associated with climate change.
The analysis, published on Wednesday, took into account 12 large European cities chosen by such factors as their size, a variety of location and because warm alerts were released, including Madrid, Barcelona, Lisbon, Paris, London, Frankfurt, Milan, Rome, Sassari (Sardinia), Athens, Budapest and Zigrab.
Climate change caused by man tripled the estimated number of deaths associated with heat, from June 23 to July 2 in these 12 European cities, according to a study conducted by scientists from the Imperial College and the London Hygiene and Tropical Medicine.
According to the study, about 2300 people died from extreme temperatures in the above cities. However, if the weather did not heat up for the burning of fossil fuel, it was estimated that it would be about 1,500 deaths less, which means that climate change is responsible for 65% of this excess death.
“This study shows why Thermal waves are known as silent killersThe questionnaires while in Spain, France and Italy reported some deaths, according to estimates, thousands of people died from temperature points, and their death will not be registered as related to warmth, ”the Malcolm Mistolm, the attached professor of the London school of tropical hygiene and medicine.
Thus, in Madrid about 118 people died over the same period of time and 108 were associated with climate changeAccording to the report. In Barcelona, 340 people died from high temperatures, and 286 were associated with climate change, according to the study.
Researchers observed an “interesting” comparison between the two cities, because, despite the fact that Madrid reached Higher average temperature in five days Sample of the study (30.16 degrees) that Barcelona (29.04 degrees), Death in the Catalan capital was amazingly excellent.
“This is a clear sign that there are clear differences in vulnerability between both cities (…) there is evidence that People in BarcelonaFor reasons that we did not take into account in the study, This is more vulnerableThis questionnaire may be associated with a share of more vulnerable housing for one person, for example, ”said one of the scientists responsible for the report on the press conference in Brussels.
In addition, the study emphasized that Madrid suffers from a rapid increase in temperature intensity Of the heat waves from climate change, about 3.68 degrees in the last wave of registered heat in relation to other cities, such as Lisbon, which increased by 1.13 degrees.
In this sense, one of the researchers pointed to the key factor, although not unique, the fact that Madrid This is inside the Iberian Peninsula And their temperature in thermal waves increased more noticeably compared to other cities.
“Madrid is practically in the center of Spain and not very coastal, which does not happen in Lisbon, for example, where we find a relatively small increase in the strong heat from the climate change, and this is because the ocean heats up more slowly than the earth,” the scientist said.
In addition, the study came to the conclusion that People over 65 represented 88% of deaths associated with climate changeWhich emphasizes that people with the main diseases are those who undergo the greatest risk of premature death during heat waves. ”
