New York - The death toll from heatwaves could rise by up to 2 000 percent in some parts of the world by 2080, according to a study released on Tuesday, as large parts of the northern hemisphere reeled from unusually high temperatures.
Scientists have long warned that climate change will bring more extreme weather across the globe, from heatwaves to hurricanes.
The researchers behind the latest study say it is the largest yet on the death toll of heatwaves, which they predict will increase in frequency and severity.
"Future heatwaves, in particular, will be more frequent, more intense and will last much longer," said Yuming Guo, associate professor at Australia's Monash University, in a statement.
"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."
