2014 - 2017年海洋热浪在全世界造成创纪录的珊瑚漂白和死亡,而气候变化使情况进一步恶化,新的全球漂白事件始于2023年。 A 2014–2017 marine heatwave caused record coral bleaching and death worldwide, worsened by climate change, with a new global bleaching event beginning in 2023.

一项全球研究表明,2014年至2017年的三年海洋热浪导致世界51%的珊瑚礁出现严重的珊瑚漂白现象,其中15%的珊瑚礁死亡率极高,这是记录上最广泛和最严重的事件。 A global study reveals that a three-year marine heatwave from 2014 to 2017 caused severe coral bleaching across 51% of the world’s reefs, with 15% suffering significant mortality—the most extensive and severe event on record. 科学家将损害归因于与气候变化有关的海洋温度上升,迫使珊瑚驱逐重要藻类,导致饥饿和死亡。 Scientists attribute the damage to rising ocean temperatures linked to climate change, which forced corals to expel vital algae, leading to starvation and death. 该事件标记为“第三次全球冲洗事件”, 持续时间比以前更长, 使珊瑚礁没有多少时间可以恢复。 The event, labeled the "Third Global Bleaching Event," lasted longer than previous episodes, leaving reefs little time to recover. 2023年开始的一个新的“第四次全球冲洗事件”也显示出类似的极端热应激, 巴拿马太平洋海岸等地区遭受前所未有的珊瑚损失。 A new "Fourth Global Bleaching Event" began in 2023 and shows similarly extreme heat stress, with some regions like Panama’s Pacific coast experiencing unprecedented coral loss. 全球气温现已超过工业化前水平的1.5°C以上,这是引起人们关切的一个关键临界点,即大多数热带珊瑚礁可能面临不可逆转的损害,而温室气体排放量却不会迅速减少。 Global temperatures have now exceeded 1.5°C above preindustrial levels—identified as a critical threshold—raising concerns that most tropical coral reefs may face irreversible damage without rapid reductions in greenhouse gas emissions.
