Coral bleaching occurs when corals expel the algae living in their tissues due to stress, such as high sea temperatures. Bleached coral is more susceptible to disease and death. Climate change, by causing rising sea temperatures, is the primary driver of coral bleaching events. The IPCC (Intergovernmental Panel on Climate Change) reports that coral bleaching events are becoming more frequent and severe due to global warming.
7.3 How does ocean acidification harm coral?
Ocean acidification, caused by the absorption of excess carbon dioxide from the atmosphere into the ocean, reduces the availability of calcium carbonate, which corals need to build their skeletons. This makes it harder for corals to grow and maintain their structures. A study by the Australian Institute of Marine Science found that ocean acidification is slowing coral growth rates in the Great Barrier Reef.
7.4 What is the impact of extreme weather events on the reef?
Extreme weather events, such as cyclones and floods, can cause physical damage to coral reefs and disrupt the marine environment. Strong waves and storm surges can break apart coral structures, and heavy rainfall can lead to increased runoff and sedimentation.
