Hotter summers could kill millions in Europe by 2100
Without significant cuts to carbon emissions and adaptation efforts, Europe could face up to 2.3 million heat-related deaths annually by the century’s end, a study finds.
Seth Borenstein reports for The Associated Press.
In short:
- Climate simulations predict heat deaths in southern Europe will surge, especially in Italy, Spain and Greece, as cold-related deaths decline in less populated northern regions.
- Even under optimistic climate scenarios, rising temperatures result in a net increase in heat-related deaths, particularly affecting older and vulnerable populations.
- Europe’s aging population and lack of widespread air conditioning heighten risks; wealthier western Europe is better equipped than the east to adapt.
Key quote:
“When you think about summertime daytime temperatures in places like Rome — they start to get up into the 40s (celsius)... That’s very heat stress/heat stroke territory for healthy young people and very dangerous for older people, particularly if they don’t have air conditioning.”
— Dr. Courtney Howard, vice chair of the Global Climate and Health Alliance
Why this matters:
Rising temperatures, increasingly frequent heatwaves and shifting weather patterns are creating new health challenges, exacerbating existing ones and placing a growing burden on healthcare systems. In Europe, where the population is aging rapidly, the risks are compounded. Older adults are more vulnerable to heat-related illnesses like heat exhaustion and heatstroke, as well as chronic conditions that can be worsened by extreme temperatures, such as cardiovascular and respiratory diseases. Without urgent action to curb emissions and adapt infrastructure, experts warn that heat-related deaths could rise sharply in the coming decades.
