In 2022, Spain made headlines as the first nation to officially name heatwaves, a move that sparked discussions in Australia about adopting a similar approach. In Australia, heatwaves claim more lives and result in more hospital admissions annually than any other natural hazard, leading some to consider this strategy as a potential lifesaver.
However, the concept of naming heatwaves has its skeptics. A study conducted in the UK in 2025 concluded that assigning names to heatwaves did not significantly alter public perception of their risk. Furthermore, it did little to motivate people to take necessary precautions. The World Meteorological Organisation also noted that this practice could divert attention from those most vulnerable during such extreme weather events.
Despite these criticisms, some experts believe it’s a topic worth exploring further, especially as climate change leads to an increase in the frequency and intensity of heatwaves. This is a sentiment echoed by Dr. Annette Stellema, a research engineer from CSIRO, who highlights the alarming rise in global temperatures and the subsequent record-breaking heatwaves.
Recently, these extreme conditions were starkly evident when a town in South Australia and the state of Victoria experienced their hottest days ever recorded. These instances underscore the urgency of addressing the implications of heatwaves as part of the broader climate crisis.
CSIRO research engineer Dr Annette Stellema said rising temperatures around the world were leading to new heat records.
Just in the past week, a South Australian town and the state of Victoria recorded their hottest days on record.
“Australia’s climate has warmed by an average of 1.51 degrees since national records began in 1910, which has led to an increase in the frequency of extreme heat events,” Stellema said.
“It’s expected that in the coming decades, Australia will experience ongoing changes to its weather and climate, with a continued increase in air temperatures, with more heat extremes.”
