Want a simple explanation of climate change and how SA is responding to it? Here’s what you need to know.
South Australians have been taking action to tackle the challenges of rising temperatures, changing rainfall patterns and rising sea level.
The state government has just set out its new policy directions to help mitigate climate change, unlock new jobs and economic growth, as well as enhance South Australia’s liveability.
Before we explain what that will look like, let’s start with some basics about climate change and its impact on our state.
What is climate change and what does it impact?
The term ‘climate change’ refers to a long-term change to climate, like temperature and rainfall.
Scientists say our climate is warming and that this warming is being caused by excess carbon dioxide being released into the atmosphere.
Excess carbon dioxide is caused by the use of carbon-rich materials like oil, coal and natural gas, which give energy to things like cars, planes, trains and heaters.
It causes the planet to heat up by acting as a blanket that traps heat near the surface.
This has a number of impacts like hotter days, less rainfall, rising sea levels and a greater number of extreme weather events such as floods, storms and bushfires.
How much is South Australia’s climate changing?
South Australia is becoming hotter and drier, with more frequent and intense extreme weather events.
This includes hotter days and longer heat waves, less rainfall overall, more days of extreme fire danger, sea level rises (estimated to be up to 0.8 metres by 2100) that will, in turn, increase coastal erosion, and heavy rainfall events that will increase the risk flooding.
How will climate change impact South Australians?
A hotter and drier climate and more extreme weather events will affect our economy and lifestyle.
- hotter weather increasing the risk of people experiencing heat stress
- extreme weather events causing property damage, which incur repair costs
- hotter weather drying up rivers and lakes, impacting food and water availability.
While we need to manage these risks, there are also opportunities to innovate and create new goods and services that reduce the amount of carbon dioxide that is released into the atmosphere.
What has been done to respond to climate change in South Australia?
South Australia is a leader in the clean energy transition, with success stories in solar energy, wind power and battery storage.
This has helped South Australia reduce its carbon emissions by 39 per cent since 1990.
Innovation hubs like the Tonsley Innovation District are bringing together research and education, as well as business and start-ups, to foster industries like clean technology and renewable energy.
Our state is also supporting communities and environments to adapt, with strong initiatives guiding coastal protection, urban greening and water sensitive urban design. A Blue Carbon Strategy for South Australia to protect coastal environments and store carbon has just been released and a renewable hydrogen industry is also being developed.
What’s next for South Australia?
Over time it is expected that SA will increase the amount of energy generated from renewable sources, such as wind and solar, and export this renewable energy to other states.
Using more renewable energy like this and less carbon-rich materials like coal, will help to reduce the amount of carbon dioxide emitted into the atmosphere.
A Directions for a Climate Smart South Australia paper has been released to set the agenda for the state government to develop other innovative ways to respond to climate change for the state.
It details five key policy directions to guide climate smart planning and action across government.
These policy directions will work to achieve a climate smart state that is more liveable and resilient, jobs and growth that are low carbon emissions and socially responsible and net-zero emissions for South Australia by 2050.
The state government is now working on a new whole-of-government climate change strategy that will include practical initiatives to respond to climate change.
