Cleaning Up: Leadership in an Age of Climate Change24 Sep 2025

Can We Save the Great Barrier Reef? | Ep225: Dr Katharina Fabricius

Why should we care about coral reefs? What happens when they collapse? And is there still hope for their survival?

In this episode of Cleaning Up, Bryony Worthington sits down with coral reef ecologist Dr. Katharina Fabricius, who has witnessed six mass bleaching events on the Great Barrier Reef over her three decades of research.

From the “seven sins of climate change” threatening reefs — heat waves, acidification, storms, nutrient runoff, and more — to the resilience and surprising adaptability of corals, Katharina offers a sobering yet hopeful look at the future of our oceans. Together, they explore the science, politics, and moral responsibility of protecting one of the world’s most critical ecosystems, and why the fate of coral reefs is deeply tied to human survival.
