The Great Barrier Reef is one of the most visible icons of Australia. It is under threat and we must act now to save it.
Ove Hoegh-Guldberg

As chief scientist of the Great Barrier Reef Foundation Ove Hoegh-Guldberg has dedicated his career to understanding climate impact on coral reef ecosystems. In the 1980s he was among the first to warn of the vulnerability of reef systems and in the decades since has led collaborative research into coral adaptation and conservation. See Hoegh-Guldberg in conversation with Nate Byrne, recorded live at Powerhouse Ultimo as part of 100 Climate Conversations. Free. Bookings essential.

Professor Ove Hoegh-Guldberg is the Chief Scientist of the Great Barrier Reef Foundation and has spent four decades studying how ocean warming and acidification threaten marine ecosystems. He authored a landmark 1999 research paper predicting the loss of coral reefs globally by 2050. Since then, he has advocated for 50 global conservation areas to ensure the future of coral on the planet. His advocacy work also includes contributing to the Intergovernmental Panel on Climate Change.


Nate Byrne is a meteorologist, oceanographer, science communicator and former navy officer, but is perhaps best known for his high-energy ABC News Breakfast weather broadcasts.
