A study by Monash University has revealed that heatwaves caused 1,009 deaths in Australia between 2016 and 2019, with Queensland and New South Wales exhibiting the highest mortality rates. The research analyzed over 249,000 death records and local temperature data, showing that older populations, those with gender imbalances, and economically disadvantaged communities faced higher risks.
Heatwaves primarily impacted deaths from cardiovascular and respiratory issues rather than cancer. The study indicated a concerning trend: if global warming continues, heat-related deaths could increase significantly, with projections of a 190% rise in Sydney and 126% in Melbourne at 2°C warming, and even more drastic increases at 3°C.
Health professionals noted rising hospital admissions due to heat-related illnesses, along with hidden impacts on respiratory and cardiovascular conditions. The findings highlight the urgent need for measures to help vulnerable communities adapt to escalating climate risks, as heatwaves are often seen as “silent killers.” Experts stress the importance of addressing these issues at all levels, from individual awareness to government action.
