The clock is ticking on climate change. A recent report by the Intergovernmental Panel on Climate Change (IPCC) warns of severe consequences if we do not curb global warming. Rising sea levels, extreme weather events, and resource scarcity are just some of the challenges we face.

Australia is one of the most vulnerable countries to climate change due to its unique geography and climate patterns. Its average temperature has increased by 1.47 ± 0.24 °C since national records began in 1910. This makes Australia one of the fastest-warming developed countries globally according to the Australian Bureau of Meteorology’s (BOM) 2022 State of the Climate. Rainfall patterns are shifting, with some areas experiencing increased rainfall (particularly northern Australia) and others facing more frequent droughts (especially southern Australia). CISRO reported that since 1970, there has been a decline of around 15% in April to October rainfall in southwest Australia and a 19% decrease in May to July rainfall in the same region. The number and intensity of extreme weather events like heatwaves, droughts, floods, and bushfires have increased significantly in recent decades. The duration and frequency of heatwaves have increased since 1970.

In this critical juncture, information technology (IT) appears as a powerful ally in the fight for environmental sustainability. IT solutions can play a transformative role in reducing our carbon footprint, improving resource management, and building resilience against climate change impacts.
