Canberra:  Australia is facing intensifying climate threats as extreme weather events become more frequent and severe, according to a government report released ahead of the country’s upcoming emissions reduction target announcement. The report highlights the urgent need for stronger climate action to protect communities, infrastructure, and ecosystems.

The assessment warns of “cascading, compounding, and concurrent” climate risks that could overwhelm multiple sectors, including healthcare, agriculture, and urban infrastructure. Heatwaves, marine heatwaves, sea-level rise, and ecosystem disruption are projected to have far-reaching consequences across the nation.

The report projects that the number of extreme heatwave days could increase from four to 18 annually, with cities like Sydney facing a potential 444% rise in heatwave-related fatalities. Marine heatwaves are expected to extend from 18 to 200 days per year, threatening marine biodiversity and fisheries. Rising sea levels could endanger millions of Australians in coastal regions, while native species may face heightened risks of extinction unless they adapt or relocate.

These climate impacts are anticipated to strain healthcare systems, reduce agricultural yields, increase rebuilding costs, and depress property values, particularly in vulnerable areas such as northern Australia, remote communities, and outer suburbs.

In response, the Australian government is preparing to announce a new 2035 emissions reduction target. Climate and Energy Minister Chris Bowen emphasized the urgency of immediate action, stating that no Australian community will be immune from climate risks. Current government goals include reducing emissions by 43% by 2030 and reaching net-zero emissions by 2050.

A national adaptation plan has also been released, outlining strategies to strengthen resilience across communities and industries. Experts note that Australia’s climate challenges reflect a global trend of increasing climate-related risks and underline the importance of ambitious and timely climate policies.

The upcoming emissions target announcement will be a critical step in shaping Australia’s response to the escalating climate crisis and determining the country’s ability to protect its economy, ecosystems, and citizens from future climate impacts.
