Executive Summary
Studies and commentary say climate change is making Australian heatwaves hotter and more frequent, raising health risks and fire danger.
- Human-caused climate change made the early January Australia heatwave about five times more likely
- Researchers estimated climate change added about 1.6C to the heatwave temperatures
- Similar three-day heat events have shifted from once every 25 years to about once every five years
- Under further warming, similar heatwaves could occur about every two years by century end
- Melbourne reached 44.4C and one hospital reported a 25 percent rise in emergency admissions
- The heatwave helped drive bushfires in Victoria, where authorities declared a state of disaster
- Solar power met about 60 percent of peak demand during the heatwave, helping support the grid
Quick Facts
- What: Climate change intensified heatwaves and raised fire and health risks
- Where: Southeastern Australia, including Melbourne and Victoria
- Why: Continued warming from fossil fuel emissions is raising extreme heat likelihood
- Who: World Weather Attribution researchers and Australian climate scientists
- When: Early January 2026 and late January 2026
