Climate change exacerbates the impact of tourism on the Great Barrier Reef by increasing ocean temperatures, leading to coral bleaching and making the reef more vulnerable to other stressors. Warmer waters cause corals to expel the algae that live in their tissues, resulting in coral bleaching and potential death.
4.1 Coral Bleaching
Rising ocean temperatures are the primary driver of coral bleaching events. When water temperatures exceed normal levels, corals become stressed and expel the symbiotic algae (zooxanthellae) that provide them with food and color. Bleached corals are more susceptible to disease and death. According to the Intergovernmental Panel on Climate Change (IPCC), coral bleaching events are becoming more frequent and severe due to climate change.
4.2 Ocean Acidification
Increased levels of carbon dioxide in the atmosphere lead to ocean acidification, which reduces the ability of corals to build their skeletons. As the ocean becomes more acidic, it becomes harder for corals to absorb the calcium carbonate they need to grow and maintain their structures. This weakens the reef and makes it more vulnerable to erosion and damage.
