Heat killed 50,000 people in European cities this summer, study finds

scienceOct 23, 202621302

Researchers estimate extreme heat killed a record 50,000 people across 854 European cities between June and August, with scientists attributing about two in every three of those deaths to human-caused climate change. The study modelled historical relationships between heat and health and found the extra warmth from fossil fuel pollution cut short roughly 32,000 lives in urban areas, leaving morgues and funeral homes full during the summer. Heat mortality this summer was nearly double each of the two next most dangerous years. Age-standardised rates were highest in Malta, Italy and Hungary, while absolute tolls were largest in Italy, France, Spain, Germany and the UK; the UK estimate was 4,354 heat deaths. Naples was the hardest-hit city, with 815 deaths per million and a 15 percent jump in emergency room visits during the hottest weeks. People aged over 85 accounted for almost half the deaths, though 833 people aged 20 to 44 were also estimated to have died. The cities in the study cover about 40 percent of Europe’s population, so the authors say these urban estimates cannot be simply extrapolated to the whole continent.

About 2/3 of the 50,000 deaths from the summer heatwaves in Europe are attributable to climate change, say Imperial College researchers That's risen from 2/5 at the start of the century Note that heat deaths are projected to rise faster than cold deaths fall www.theguardian.com/environment/...

50,391 heat-related deaths across 854 European cities in one summer. Of these, 32,619 were attributed to the extra heat caused by burning coal, oil and gas. Now tell me climate action isn’t essential... www.independent.co.uk/news/arctic-...

This paper was enabled by the published temperature/mortality response functions of Masselot et al. for 854 European cities demonstrating how important these functions are. Unfortunately, the underlying daily mortality data in the US & elsewhere is nearly impossible to obtain. At least for me 🥵

If this death toll was the result of a terrorist attack, the world would be up in arms And remember, this is not the new normal From the perspective of 2100, or even 2050, the summer of 2026 will be one of the coolest www.theguardian.com/environment/...

Impossible , governments in Italy and Hungary banned climate change.

Auch so eine Zahl die im Politikbetrieb nahezu ausgeblendet wird. Klima war gestern, jetzt redet man wieder lieber über Ausländer und extremistische Linke.

«Neue Forschungsergebnisse deuten darauf hin, dass in diesem Sommer in europäischen Städten die Rekordzahl von 50.000 Menschen an der #Hitze gestorben ist. Wissenschaftler machen den #Klimawandel für zwei von drei Todesfällen verantwortlich.»

Scientists estimate that over 50,000 people died prematurely because of high temperatures across 854 European cities between June and August this year, making it Europe's deadliest summer heat on record.

With scientists finding 32,000 urban heat deaths were directly caused by global warming, and over 4,300 in the UK alone, government inaction on net zero is deadly. When will ministers insulate homes, green urban infrastructure, and phase out fossil fuels? #ClimateAction

www.theguardian.com/environment/... If this was a novel virus, and the death toll was recurring annually, there would be a relentless international effort to tackle it. But climate change induced deaths just aren’t given the respect they deserve.

#HeatKills: "This summer Europe experienced an estimated 50,000 heat-related deaths as high temperatures scorched the continent, making it the most deadly season for heat mortality in modern records". Which also means that *not* preparing for heatwaves is tantamount to collective suicide.

Hot weather from relentless heatwaves killed nearly twice as many people -50k in Europe alone - as it did in each of the 2 next most dangerous years. The share of deaths due to climate breakdown has risen from c40% at the start of the century to 65% this summer www.theguardian.com/environment/...
