Nights Heat Up: Climate Change Poses Health Risks to Billions

A new study by Climate Central reveals alarming increases in summer nighttime temperatures, rising 2.29℃ (36.2°F) from 1895 to 2023—double the global average increase of 1.1℃. This trend exposes billions to heat-related health risks, particularly acute and chronic diseases, Anadolu Agency reported yesterday.

Experts warn that prolonged extreme temperatures stress the human body, raising the likelihood of heat-related illnesses and fatalities. The World Health Organization reports an 85% increase in heat-related mortality among those over 65 from 2000–2004 to 2017–2021. Between 2000 and 2019, approximately 489,000 heat-related deaths occurred annually, with 45% in Asia and 36% in Europe.

The devastating 2003 heat wave in Europe, which claimed 70,000 lives, underscores the severe consequences of high-intensity heat events. As temperatures continue to rise, the need for urgent action to mitigate climate change and protect public health has never been more critical.
