Rising seas will threaten 1.5 million Australians by 2050 – report

A groundbreaking climate report has revealed that Australia is already grappling with the severe impacts of climate change, with escalating risks projected for the coming decades. The National Climate Risk Assessment, Australia’s first comprehensive climate evaluation, warns that 1.5 million coastal residents could face threats from rising sea levels by 2050. The report highlights increased frequency and intensity of climate hazards, including floods, cyclones, heatwaves, droughts, and bushfires. Climate Change Minister Chris Bowen emphasized that while Australians are already experiencing these consequences, mitigating global warming now is crucial to safeguarding future generations. The report examined three warming scenarios—above 1.5°C, 2°C, and 3°C—and found that Australia, one of the world’s highest per capita polluters, has already surpassed 1.5°C. At 3°C, heat-related deaths in Sydney could surge by over 400%, with Melbourne seeing nearly triple the current rates. The 72-page document, released ahead of the government’s 2035 emissions reduction targets, underscores that no community will be spared from cascading and compounding climate risks. It predicts a A$611 billion drop in property values, deteriorating water quality, and heightened threats to coral reefs like the Great Barrier Reef and Ningaloo Reef. Northern Australia, remote communities, and outer suburbs of major cities are particularly vulnerable. The report also warns of increased pressure on health systems, infrastructure, ecosystems, and emergency services. In response, the government unveiled a national adaptation plan to coordinate federal, state, and local efforts. Bowen reiterated Australia’s commitment to a 43% emissions reduction by 2030, though critics argue the nation’s reliance on fossil fuels remains problematic. Climate Council CEO Amanda McKenzie called for more ambitious targets, stressing that delays in reducing emissions will exacerbate the devastating impacts of heatwaves, floods, and bushfires.
