Heatwaves Cause 150,000 Deaths Annually

A recent study conducted by Monash University in Australia reveals that extreme heatwaves during the hottest four months of the year result in over 150,000 deaths globally each year.

The research highlights the severe impact of rising temperatures on public health, emphasizing the urgent need for effective measures to mitigate climate change.

Between 1990 and 2019, heatwave-related excess mortality accounted for an average of 153,078 deaths annually, equating to 236 deaths per 10 million people, or 1% of global deaths.

The study analyzed daily mortality rates and temperature data from 750 locations across 43 countries, providing a comprehensive overview of the worldwide impact of heatwaves.

While Asia recorded the highest number of estimated deaths due to heatwaves, Europe had the highest population-adjusted mortality rate, with 655 deaths per 10 million people.

Greece, Malta, and Italy were identified as having the highest rates of excess mortality linked to extreme heat.

The study also found that regions with dry climates and lower-middle-income populations experienced the highest estimated mortality rates from heatwaves.

These findings underscore the disproportionate impact of climate change on vulnerable populations and the need for targeted interventions.

The researchers emphasized the importance of understanding regional differences in heatwave mortality to develop tailored strategies for preventing heat-related deaths.

They called for increased public awareness, improved infrastructure, and policies aimed at reducing the health impacts of extreme temperatures.
