Background: It has been a decade since a landmark Lancet publication declared that 'climate change is the biggest global health threat of the 21st century'. Since then, Australia has experienced unprecedented warming related to climate change and an associated increase in the frequency and intensity of extreme weather events, including heatwaves, droughts, storms, bushfires and air pollution. These events have had major impacts on community physical and mental health.
Objective: The aim of this article is to describe the health impacts of climate change and the role of general practitioners (GPs) in responding to these impacts.
Discussion: While the clinical skills that underpin general practice have not changed, the environmental and planetary context has shifted. A 'planetary health' approach is required. Climate change should now be considered a health emergency. GPs have a critical role in mitigation and adaptation. Responding to climate change aligns with principles of preventive health and can produce 'co-benefits' for individual and population health.
