More than five million extra deaths a year can be attributed to abnormal hot and cold temperatures, according to a world first international study led by Monash University.

The study found deaths related to hot temperatures increased in all regions from 2000 to 2019, indicating that global warming due to climate change will make this mortality figure worse in the future.

The study, the first to definitively link above and below optimal temperatures (corresponding to minimum mortality temperatures) to annual increases in mortality, found 9.43 per cent of global deaths could be attributed to cold and hot temperatures. This equates to 74 excess deaths for every 100,000 people, with most deaths caused by cold exposure.

The data reveals geographic differences in the impact of non-optimal temperatures on mortality, with Eastern Europe and Sub-Saharan Africa having the highest heat and cold-related excess death rates.

Importantly, cold-related death decreased 0.51 per cent from 2000 to 2019, while heat-related death increased 0.21 per cent, leading to a reduction in net mortality due to cold and hot temperatures.
