Study lead and Monash Associate Professor Yuming Guo said the recent media reports detailing deadly heatwaves around the world highlight the importance of the heatwave study.

“Future heatwaves in particular will be more frequent, more intense and will last much longer,” Associate Professor Guo said.

“If we cannot find a way to mitigate the climate change (reduce the heatwave days) and help people adapt to heatwaves, there will be a big increase of heatwave-related deaths in the future, particularly in the poor countries located around the equator.”

A key finding of the study shows that under the extreme scenario, there will be a 471 per cent increase in deaths caused by heatwaves in three Australian cities (Brisbane, Sydney and Melbourne) in comparison with the period 1971-2010.

“If the Australia government cannot put effort into reducing the impacts of heatwaves, more people will die because of heatwaves in the future,” Associate Professor Guo said.
