The Commonwealth’s five-year report card said the outlook for Australia’s world heritage ecosystem is very poor, with global warming the biggest threat.
Ongoing damage to the health and beauty of the Great Barrier Reef by global warming is inevitable, delivering major blows to local communities and the national economy, according to the Commonwealth’s five-yearly health check of Australia’s world heritage listed coral wonder.
Queensland marine tourism is estimated to be worth $36 million a year, generating more than 200,000 jobs.The outlook report said the reef provides a living for hundreds of thousands of people, making a significant contribution to the state and national economies. It found that a healthy reef boosts the mental and physical health of people who interact with it and contributes to Australia’s national identity.
Of the past 400 years, the six hottest years for sea surface temperatures on the Great Barrier Reef have occurred since 2016, according to an Australian study,The Intergovernmental Panel on Climate Change , the United Nations body for assessing global warming, has found that if global average temperatures – which are currently 1.1 degrees above the pre-industrial average – rise by 1.5 degrees, then 70 to 90 per cent of the world’s coral reefs will die.
