無(wú)法抗拒之“暖”——與海洋酸化相比，日益上升的氣溫是對(duì)珊瑚更為直接的威脅。珊瑚，尤其是熱帶珊瑚，適應(yīng)氣候的能力較弱，極易受到海水表面高溫的傷害。當(dāng)海水溫度升高時(shí)，與珊瑚共生的藻類(lèi)就會(huì)大量離開(kāi)，成片的彩色珊瑚因此會(huì)變得像骨頭一樣慘白，而后很快死去，這種現(xiàn)象被稱為珊瑚白化或“白色瘟疫”。
Cral Reefs: the First Indicatr f Climate Change
Here in the nrthern Red Sea in the Bay f Aqaba, Israeli scientists have discvered smething extrardinary. Despite higher water temperatures, these crals are healthy and even thriving. We fund that crals are nt bleaching①. We've never witnessed any bleaching event which is s cmmn elsewhere. T find ut why, small crals were subjected t② bleaching cnditins in the labratry. Their ruddy③ clur is a sign f gd health. Bleaching cnditins are usually cnsidered as 1 t 2 degrees abve the summer maximum and there was n bleaching. We elevated the temperature furthermre and nly at 5 and 6 degrees abve sme maximum, they shwed signs f stress and bleaching.
But hw can the crals here withstand④ such high temperatures when mass cral bleaching is ccurring elsewhere? The answer may be fund 18,000 years ag when the Red Sea was much htter. In rder t survive cnditins, very ht cnditins in the suthern Red Sea, they had t be r underg selectin twards thermally resilient (適應(yīng)力強(qiáng)的) crals. Thse that suffer frm the ht, the very ht cnditins dwn there didn't survive, and s crals that we see here nwadays are the nes that are descendants f the nes that survived. The study als indicates that future generatins f cral in the Bay f Aqaba will als be immune t⑤ bleaching. And while we're aware that temperatures are rising in the Gulf f Aqaba, perhaps at a faster rate than the glbal average, still we have abut a hundred years befre these crals will experience bleaching cnditins r crss the bleaching threshld⑥. Cral reefs are ften the first indicatr f climate change. Their lss wuld raise the risk f extinctin f thusands f fish species and ther marine life.
