全球暖化令海水溫度上升，導致珊瑚大規模死亡，澳洲大堡礁過去25年失去一半以上的珊瑚。大量海洋生物依賴珊瑚礁作非常重要的棲息、覓食及繁殖的地方。大堡礁是全球最大的珊瑚礁，當區的生物數量及多樣性都大量下降，必需盡快減少溫室氣體排放量來減輕對珊瑚的影響。

Ocean water temperature is too high due to climate change and is killing coral. Over 50% of the corals in the Great Barrier Reef have died in the past 25 years. many marine creatures rely on the coral reefs; it is an important place for living, foraging and reproduction. The Great Barrier Reef is the largest coral reef in the world, but the biodiversity and number of marine creatures have dropped significantly due to the loss of coral. It is necessary to reduce greenhouse gas emissions as soon as possible to reduce the impact on corals.
