Tomorrow marks the eighth anniversary of the worst bushfires in Australian history – the Black Saturday fires in Victoria. This firestorm killed 173 people, injured 5000, affected 109 communities and damaged or destroyed 3500 buildings. For the doctors, nurses and psychologists called to respond, and who continue to deal with its aftermath, now is a time not only to reflect on lessons of the past, but to prepare for the future. We know climate change is making extreme weather events – bushfires, droughts and heatwaves, storms and floods – more frequent and severe. All of these disasters harm the health of our patients and communities.
