Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae living in their tissues causing the coral to turn completely white. In 2020, the Great Barrier Reef suffers for the third time in five years from mass coral bleaching. When bleaching is severe, many corals die. According to scientists, coral bleaching is now affecting around 60 percent of the Great Barrier Reef.
Due to climate change, summers are getting hotter and will cause more and more mass bleaching. The Great Barrier Reef will continue to lose corals until global climate change will be under control and sea temperatures stabilize. Without taking urgent actions, facing climate change, coral reefs will not survive.
