Climate change could increase heat wave deaths 2,000 percent by 2080

According to the paper led by researchers at the Monash University (published on 1 August in PLOS Medicine), if people can not adapt to future temperatures, the risk of death caused by heat waves will increase dramatically.

Published today in PLOS Medicine, the study recommends reducing greenhouse gas emissions at a high level to decrease future deaths related to heatwaves.

Researchers from Monash University in Melbourne, Australia devised a model that analysed heatwaves in 412 communities across 20 countries from the years 2031 to 2080.

A team of global researchers based their findings on various scientific models, which predicted that under the most extreme scenarios there would be a 471 per cent rise in deaths as a result of heatwaves in Brisbane, Sydney and Melbourne between 2031 and 2080 compared with the four decades to 2010.

Scientists warn that in the future heat waves will be more intense and they will last longer.

"If the Australian government can not put effort into reducing the impacts of heatwaves, more people will die because of heatwaves in the future", Assoc Prof Guo said as the study was published in the journal PLOS Medicine on Wednesday.


The study comes as many countries around the world have been affected by severe heatwaves, leaving thousands dead and tens of thousands more suffering from heatstroke-related illnesses.

Significantly increase the number of victims Greece, India, Japan and Canada.

Antonio Gasparrini, an expert from the London School of Hygiene & Tropical Medicine who co-led the research, noted that several countries around the world are now being hit by deadly heatwaves and said it was "highly likely" that heatwave frequency and severity would increase under a changing climate.

"Worryingly, research shows that it is highly likely that there will be an increase in their frequency and severity under a changing climate", Gasparrini said.

Excess mortality will increase sharply in tropical and subtropical countries and regions while European countries and the United States will have a smaller percent increase in deaths related to heat waves, according to the study by researchers from Monash University in Melbourne.

Associate Professor Gasparrini said he hoped the study's projections would support decision makes in planning crucial adaptation and mitigation strategies for climate change.
