Health impacts of climate change
Climate change can affect human health including through:
- rising heat
- changing rainfall patterns causing floods or drought
- climate-sensitive air quality issues
- changing vectorborne, waterborne or foodborne infectious diseases
- reduced nutritional value of crops.
As a result, some of the direct impacts of climate change on health include:
- heat-related morbidity and mortality
- increased respiratory illnesses
- rising injuries and fatalities due to extreme weather events.
Bushfire season in Australia is becoming longer and more intense due to climate change. The main health risk associated with bushfires is smoke inhalation.
Common symptoms of exposure to bushfire smoke can include:
- eye, nose, mouth and throat irritation
- coughing including producing sputum

Building a sustainable health system
The Department of Climate Change, Energy, the Environment and Water is the main department responsible for coordinating how the Australian Government adapts to climate change. Every 5 years the department issues the State of the Environment report. The report provides an independent, comprehensive and evidence-based assessment of the state of Australia’s environment.
The Australian Government is taking strong action to build climate resilience for our future generations. As part of its response, we are focused on developing a sustainable and responsive health system.
The National Health and Medical Research Council is increasing climate and health research capacity and capability through the Special Initiative in Human Health and Environmental Change. The initiative will help strengthen our health system’s resilience, preparedness, and responsiveness to changing environmental conditions and extreme weather events.
