Evaluating 38 years of coral coverage trends on the Great Barrier Reef: insights into resilience and temperature correlation
by Alberto Boretti
International Journal of Global Warming (IJGW), Vol. 36, No. 4, 2025

Abstract: This study investigates the relationship between global warming and coral reef health, focusing on the Great Barrier Reef (GBR). Contrary to claims of widespread decline due to warming-induced bleaching, long-term data from the Australian Institute of Marine Science (AIMS) reveal that coral cover is at its highest since monitoring began in 1985. Using satellite air temperature data as a robust proxy for ocean warming, the analysis identifies no consistent correlation between rising temperatures and reduced coral cover. Coral bleaching is reframed as an adaptive response, with most corals demonstrating rapid recovery. These findings challenge prevailing narratives of coral fragility, emphasising the GBR's resilience and adaptive capacity in the face of climate change. The study advocates for balanced scientific discussions that incorporate both threats and recovery dynamics in coral ecosystems.
