Australia's National Climate Risk Assessment warns of $611 billion in property losses and a potential 400% rise in heat-related deaths in Sydney if global warming reaches 3°C by 2050.

  • A landmark report released on September 15, 2025, warned that rising oceans and flooding will threaten homes and livelihoods of over 1.5 million Australians by 2050.

  • The findings imply urgent action is needed, as heat-related deaths will soar and property losses could reach Aus$611 billion by 2050, while the government aims for net-zero emissions by 2050.
