Heatwaves to kill 6000 Aussies every year by 2100

The number of Australians dying from heatwaves will increase exponentially due to climate change. Nearly 6,000 will die every year by 2100, a new Australian study shows.

This staggering figure represents a death toll twenty-four times higher than the current figure.

Although extreme heat killed around 250 Australians each year between 2016 and 2019, rapid warming of the continent is expected to push the annual death rate to 5,913 by the turn of the century.

In the Northern Territory, deaths from heatwaves are expected to rise by as much as 4,412 percent.

Even in areas least affected by the heat, such as the west coast of South Australia, the impact remains significant, with a predicted 356 percent increase in deaths.

Researchers analyzed climate data from more than 2,200 communities across Australia to map the geographic burden of rising temperatures.

The findings indicate that the Northern Territory will experience the highest annual mortality rate in the decade 2090-2099, at 33.9 deaths per 100,000 population.

Queensland follows with 18.4 deaths, while New South Wales is expected to suffer 12.8 deaths per 100,000 residents.

Lead researcher Professor Shandy Li said the projections underline the urgent need for integrated mitigation and locally tailored adaptation strategies to tackle climate-related health inequalities.

Heat waves are defined as prolonged periods of extremely hot weather and are known to cause a sharp increase in illnesses and deaths related to cardiovascular, respiratory and kidney diseases.

The study highlights that the most vulnerable Australians will bear the heaviest burden.

Co-lead author Professor Yuming Guo noted that the northern and inland regions are particularly at risk. These areas often have higher indigenous populations and often suffer from inadequate access to refrigeration and medical supplies.

“Northern and inland regions, where indigenous people comprise a larger proportion of the population compared to other regions and access to cooling and medical supplies is inadequate, are particularly vulnerable to the effects of heat waves,” said Professor Guo.

“Without coordinated action, climate change will significantly worsen the health impacts of extreme heat and strain the resilience of public health across Australia,” he said.
