Australia's Coral Reefs at 'Extremely High Risk' of Collapse by 2075, Global Assessment Warns

Every shallow-water coral reef ecosystem in Australia faces an 'extremely high risk' of collapse by 2075, according to a stark new global assessment. The primary driver is projected ocean warming, which threatens to devastate the iconic Great Barrier Reef and other vital marine habitats. The assessment, which evaluated reef ecosystems worldwide, places Australia's reefs among the most vulnerable due to rapidly rising sea temperatures and marine heatwaves. Without drastic and immediate action to curb greenhouse gas emissions, scientists warn that the structural and functional collapse of these reefs could occur within the next 50 years, leading to catastrophic losses in biodiversity, coastal protection, and fisheries. The findings underscore the urgent need for global climate policy and local conservation measures to safeguard reef resilience. The window to prevent irreversible damage is closing fast.
