What You'll Learn
Health and well-being
Climate change is a major public health concern in Australia, with unprecedented wildfires, heatwaves, floods, droughts, and the spread of climate-sensitive infectious diseases all impacting the health and well-being of Australians. The World Health Organization has described climate change as the biggest threat to health in the 21st century. The effects of climate change on health are both direct and indirect.
Direct effects include the increased intensity and frequency of extreme weather events, such as heatwaves, floods, and bushfires, which can result in burns, injuries, mental health issues, and death. Heatwaves in Australia kill more people than all other natural disasters combined, with more than 1000 people over the age of 65 dying each year in heatwaves. Warmer temperatures can also worsen symptoms of heart and lung disease.
Indirect effects include worsening air quality, changes in the spread of infectious diseases, threats to food and water security, and impacts on mental health. Bushfires, for example, release various air pollutants, including particulate matter (PM2.5), which can travel long distances and affect a large population, causing eye irritation, cardiorespiratory issues, and adverse birth outcomes. Children, the elderly, pregnant women, outdoor workers, and people with pre-existing cardiorespiratory conditions or living in disadvantaged communities are particularly vulnerable to the health risks associated with bushfire smoke.
Climate change has also led to longer droughts, more severe floods, saltwater intrusion into freshwater sources, reef bleaching, and increased storm damage. These events make accessing adequate food, water, and shelter more challenging, further impacting the health and well-being of Australians. Additionally, the loss of habitable land, houses, and sites of cultural significance, as well as concerns about the future, have contributed to "climate anxiety", grief, and depression across Australia. Mental health organizations are providing support to individuals of all ages to manage these conditions.
To mitigate the impacts of climate change on health and well-being, Australia has developed its first National Health and Climate Strategy, aiming to address these impacts and reduce the health system's emissions, waste, and contribution to climate change. Additionally, green spaces in urban environments help to reduce heat impacts and improve air and water quality, while also providing recreational activities that are important for human health and well-being.

National security
Climate change is a growing concern for Australia's national security. The country's geographical position, with its long coastline and many settlements close to the coast, makes it vulnerable to rising sea levels and increasingly frequent extreme weather events. These include heatwaves, bushfires, cyclones, droughts, and floods, all of which have been linked to climate change.
The Australian Defence Force (ADF) is a key responder to these climate-related disasters, both domestically and in the Asia-Pacific region. The ADF's ability to respond to these events is impacted by the very disasters they are trying to mitigate. The ADF relies on civilian infrastructure, which is vulnerable to climate events. For example, the Tanami Road, crucial in the event of regional military conflict, is susceptible to heat and flood damage. The ADF's bases are also located along the coast, and many are considered at high risk of flooding and rising sea levels. The ADF's resources and personnel will be increasingly stretched as the number and severity of climate-related disasters increase. This could impact their ability to respond effectively and may reduce their military capabilities and effectiveness.
Climate change also poses a threat to Australia's critical infrastructure. By 2050, rising sea levels will threaten 120 ports, five power stations, over 250 police, fire, and ambulance stations, and 75 hospitals. Roads and railways are also at risk, either due to their coastal location or susceptibility to extreme weather. This will impact the country's energy security and transportation networks.
The impact of climate change on Australia's regional allies also has national security implications. Australia's neighbours in the South-West Pacific region are highly vulnerable to climate change and are already calling for more action from Australia. Australia's poor climate goals and performance are threatening their relationships with these nations and their ability to project power and influence in the region. This is particularly concerning given China's increasing presence and competition for influence.
Finally, climate change may increase the risk of political instability in the region. Large-scale disasters can fuel anti-government sentiment and communal conflicts, and survivors may turn to extremist groups for support. This could create a security issue for Australia and further strain their resources and relationships in the region.

Indigenous communities
Climate change has been a critical issue in Australia since the beginning of the 21st century. The country is experiencing higher temperatures, more extreme droughts, longer fire seasons, and more frequent and intense heatwaves. These changes are causing high pressures on the environment, the economy, and the Australian people.
The communities most affected by climate change are those in the north, where Aboriginal and Torres Strait Islander people make up 30% of the population. These communities are located in coastal areas and rely on traditional land for food, culture, and health. They are vulnerable to rising sea levels, increasing air and sea temperatures, and changes in ocean acidity. Climate change also impacts Indigenous people's ability to practice their culture, as it harms their connection to their homelands and traditional practices.
The effects of climate change on Indigenous communities in Australia include seasonal changes, rising seas, temperature increases, and a reduction of food and water resources. Wildfires, heatwaves, floods, cyclones, and erosion also pose significant challenges. Additionally, the health and well-being of Indigenous populations are directly and indirectly impacted by living in areas prone to extreme heat, fire weather, floods, and droughts. Existing ill-health and socio-economic disadvantages within these communities further compound the impacts of climate change.
To address the issues associated with climate change, Indigenous communities in Australia are focusing on adaptation. This includes developing good evacuation and early warning processes for natural disasters, upgrading and strengthening buildings, managing energy use, and teaching people how to stay healthy in higher temperatures. Indigenous knowledge and traditional land management techniques contribute significantly to effective adaptation strategies. Additionally, tree planting initiatives help reduce air pollution and provide shade.

Agriculture and food security
Climate change poses a significant challenge to Australia's agricultural sector, which is heavily dependent on natural resources. The country's unique climate and geography make it particularly vulnerable to the impacts of climate change, including changes in rainfall, temperature, and extreme weather events. These changes have far-reaching consequences for agricultural productivity, food security, and the overall economy.
One of the most pressing concerns is the impact on crop yields and livestock numbers. Climate change is increasing the variability of crop yields, with extreme weather events such as droughts, heatwaves, and cyclones, causing significant reductions in production. For example, the 2005-2007 drought led to a 43% increase in fresh fruit prices and a 33% increase in vegetable prices. Similarly, the 2009 heatwave in Victoria caused significant production losses in berry and other fruit crops. These events highlight the vulnerability of Australia's food supply chain to climate-related disruptions.
In addition to the direct impacts on crop yields, climate change is also affecting the areas suitable for farming. Changing climatic conditions can attract new pests and diseases, further compounding the challenges faced by farmers. As certain regions become less favourable for traditional crops, there may be a shift towards livestock and mixed farming, particularly in lower rainfall areas. This transition could have long-term implications for land use and agricultural practices.
To address these challenges, the Australian government and various state governments are committed to working with the agriculture sector to enhance its climate resilience and sustainability. This includes implementing policies and programs that promote climate-smart agricultural practices, such as reducing greenhouse gas emissions, improving water use efficiency, and adapting to changing climatic conditions. The National Statement on Climate Change and Agriculture showcases the collaboration between governments and the exceptional work already underway within the industry.
Furthermore, Australia is responding to rising global food insecurity by providing emergency food assistance, financial and technical support, and advocating for open and transparent agricultural trade. The country's development programs focus on improving productivity, sustainability, and climate resilience in the region. Additionally, Australia recognizes the importance of nutrition-sensitive agricultural investments and promoting gender equality and social inclusion in addressing food security concerns. These comprehensive approaches aim to safeguard livelihoods, ensure food availability, and build resilience in the face of climate change.

Military operations
Climate change is a significant threat to Australia's national security and will likely impact military operations in the country. As global temperatures rise, the Australian Defence Force (ADF) is experiencing an increase in emergency first responder taskings, both domestically and internationally. The changing climate intersects with Australia's physical and geopolitical environment, presenting challenges for the ADF's force structure, capacity, capability, and budget.
First-order effects of climate change, such as increased extreme climate events, will result in a more challenging operating environment for the ADF. For example, the recent wildfires in southeast Australia have directly impacted the military's capacity and strength. Higher temperatures will also affect the performance of equipment, personnel, and infrastructure. The ADF may need to modify or scrap platforms optimized for environmental conditions that no longer exist. Additionally, the range of tropical diseases will expand, requiring greater investment in military medicine and prevention.
Climate change also poses diplomatic challenges for Australia. Regional leaders have accused the country of not doing enough to address climate change, threatening its relationships with island nations in the South West Pacific region. Australia's engagement and leadership on climate change will significantly influence its diplomatic and military relations. The country's reliance on partners for forward basing and support in future conflicts underscores the importance of maintaining these relationships.
To adapt to the challenges posed by climate change, Australia can follow its allies, such as the UK, US, and New Zealand, in adopting emerging "green" technologies. By investing in and adopting these technologies early on, the ADF can gain a strategic advantage over competitors in the region and improve its ability to operate and fight in adverse environments. Additionally, the ADF can focus on cooperation with other emergency agencies and increase the authority of non-Defence organizations in domestic disaster response efforts to ensure that its contribution to domestic support operations does not significantly impact its warfighting capability.
Climate change may also alter the nature of conflicts and military operations. While tactics will continue to be shaped by technology, training, doctrine, and national preferences, personnel will need to adapt to higher temperatures and operate with available resources. Climate change can act as a threat multiplier, increasing the likelihood of conflicts over resources such as water and rare minerals. Military forces may be called upon more frequently to provide humanitarian assistance and evacuate people from disaster zones rather than fighting wars.
