Climate change & WA
Living in the world’s driest continent, we need to understand how climate change is impacting us and how we can live more sustainably. As climate change, continues to impact our state in several ways, including an increase in average annual temperatures, more extreme weather events and significant changes to rainfall, it’s never been more important to become aware of its effects on where we live.
Because Western Australia has large climate variability, the effects of climate change can vary across our expansive regions which can often lead to a lack of understanding of how it’s impacting us as individuals. Some changes, however, can be seen across most of WA, such as the increase in fire risk.
Already one of the most fire-prone regions in the world, Western Australia’s fire risk has increased over the past 4 decades, and fire seasons have lengthened due to warming and drying conditions. We have also experienced changes in sea levels, with the rate of sea-level rise on the west coast almost 3 times the global average.
Right now, we have genuine opportunities to transform the way we live and reduce our water use and carbon footprint. With increased variability of water availability around the state, it has never been more important to save our precious resource – water
In this section, you can find out how climate change is impacting where you live and learn how we are shifting to climate independent water sources, sustainable water practices and reducing water use so that we can continue to enjoy all the things that make WA a great place to live.
Climate & Perth
The impacts of climate change in Perth are evident with a significant reduction in average rainfall over the past 40 years.
Climate & Southern WA
Due to climate change, the average 20% decline in rainfall throughout the South West has seen streamflow reduce by over 80%.
Climate & the North West
Climate predictions indicate that the intervals between rainfall events will become increasingly variable across the northern regions of Western Australia over the century.
Climate & the Mid West
Changes to summer rainfall in the Mid West are a uncertain but a decrease in winter rainfall is highly likely, threatening the ongoing sustainability of our groundwater sources.
Climate & Goldfields and Agricultural
Climate change is affecting the pastoral regions of the Goldfields in different ways though in most cases, we can see an overall increase in temperatures, changes in seasonal rainfall and extended periods of drought.
