西澳大利亚沿海约2000公里范围内的珊瑚礁在2024年8月至2025年6月间经历了有记录以来最广泛的白化事件1。根据《2025年世界珊瑚礁状况》报告，热应力持续80至160天，部分地区海水温度比正常水平高出4摄氏度1。澳大利亚海洋科学研究所研究员吉尔莫表示："这是澳大利亚珊瑚礁最坏的白化事件，首次在一个事件中影响了西澳所有主要礁群"1。
灾情在不同地区的严重程度存在差异。皮尔巴拉礁群经历极度白化，死亡率超过75%；而世界遗产地宁加洛礁的白化率达30-70%，创造了澳大利亚珊瑚礁白化纪录1。该报告基于1980-2024年的数据，包含来自124个国家87,299次调查的2110万次观测1。
令人担忧的是，珊瑚礁的恢复周期正在缩短。自2010年以来，多个地区白化事件间隔期已缩短至少于10年，某些地方仅相隔数年1。科学家预测今年可能出现"超级厄尔尼诺"，预期对远北地区礁群造成最严重白化1。
Western Australia's coral reefs have endured their most severe bleaching event in recorded history, affecting approximately 2,000 kilometers of coastline between August 2024 and June 2025.1 The Pilbara reef system experienced extreme bleaching with mortality rates exceeding 75 percent, while the world heritage-listed Ningaloo reef suffered bleaching rates between 30 and 70 percent, establishing a record for Australian coral reef bleaching.1 The bleaching was driven by thermal stress lasting 80 to 160 days, with water temperatures in some areas reaching 4 degrees Celsius above normal levels.1
According to the 2025 State of World Coral Reefs report, which drew on data from 1980 to 2024 encompassing 87,299 surveys from 124 countries and 21.1 million observations, this represents an unprecedented scale of damage for Australian reefs.1 A researcher from the Australian Institute of Marine Science stated that "this is the worst bleaching event for Australian coral reefs, and the first time in a single event that all major reef systems in Western Australia have been affected."1 Scientists have observed an alarming trend: recovery intervals between bleaching events have shortened to less than 10 years since 2010, with some locations experiencing successive events separated by only years.1 Researchers predict that a possible "super El Niño" this year could inflict the most severe bleaching on far northern reef systems.1
