The National Climate Risk Assessment warns millions of Australians are at risk from rising sea levels and heat-related deaths, unless climate change can be limited.
According to the landmark report released today, the number of heat-related deaths in Sydney could soar by almost 450% if global heating surpasses 3C.
The comprehensive assessment also outlines the risks of longer fire seasons, extreme downpours, rising seas and mega-droughts — with flow-on effects for health, food and water security, infrastructure and livelihoods.
It comes as the Federal Government prepares its 2035 climate plan and bids with Pacific nations to co-host the COP31 summit.
