A recent study from the University of Queensland warns that the Great Barrier Reef is facing a 'grim future' with rapid coral decline expected over the next few decades due to global heating. However, the research also suggests that if global temperature rise is limited to 2 degrees Celsius, there is still a chance for recovery. This finding is crucial as it highlights the urgent need for climate action to protect one of the world's most iconic ecosystems, emphasizing that our choices today can significantly impact the reef's future.
