Coral Reef Bleaching Alarms Scientists
珊瑚礁白化让科学家震惊
An aerial survey of Australia's Great Barrier Reef revealed mass coral bleaching for a second year in a row. The bleaching is a result of rising temperatures caused by global warming. The back-to-back bleaching events have affected 1,500 kilometres, or two-thirds, of the reef. The results of the survey alarmed scientists and water quality experts. Some fear that the damaged coral will not be able to survive. Previous mass bleaching events took place ten years apart, giving the reef time to recover.
澳大利亚大堡礁的空中摄像表明有大量珊瑚连续两年出现白化。珊瑚白化是全球变暖导致气温上升的结果。接连不断的珊瑚白化事件影响了1500千米的范围，即大堡礁的三分之二。这个结果让科学家和水质专家很震惊。有人担心受损的珊瑚无法存活。此前珊瑚白化发生在十年前，让大堡礁有喘息的时间。
