Coral Reef Bleaching Alarms Scientists
珊瑚礁白化讓科學(xué)家震驚
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.
澳大利亞大堡礁的空中攝像表明有大量珊瑚連續(xù)兩年出現(xiàn)白化。珊瑚白化是全球變暖導(dǎo)致氣溫上升的結(jié)果。接連不斷的珊瑚白化事件影響了1500千米的范圍，即大堡礁的三分之二。這個(gè)結(jié)果讓科學(xué)家和水質(zhì)專家很震驚。有人擔(dān)心受損的珊瑚無(wú)法存活。此前珊瑚白化發(fā)生在十年前，讓大堡礁有喘息的時(shí)間。
