根据联合国政府间气候变化专门委员会(IPCC)的最新报告，这将对珊瑚非常不利。
Christopher Intagliata: Within a few decades, global temperatures are expected to climb to 1.5 degrees Celsius above pre-industrial levels. And that's gonna be really bad for corals, according to the latest report out from the Intergovernmental Panel on Climate Change.
IPCC最近的报告称，温度升高达到1.5摄氏度，珊瑚存活率有望达到10%到30%。若高于此数值，存活率会急剧下降。
Andréa Grottoli: So the recent IPCC report says that up to 1.5 we can expect 10 to 30 percent coral survivorship. And above that, it decreases precipitously.
安德烈·格罗托利是俄亥俄州立大学的著名教授。IPCC报告内容不容乐观，但格罗托里带来了一些罕见的好消息。珊瑚可能比我们想象的更能适应未来的环境。
Intagliata: Andréa Grottoli is a distinguished professor at the Ohio State University. Amid the doom and gloom of the IPCC report, Grottoli has some rare GOOD news. Corals may be more adaptable to future conditions than we thought.
她的团队研究了夏威夷瓦胡岛的三种珊瑚。他们把珊瑚放在高温应激的容器中; 放在有更多酸性水的容器中; 或放在两者都有的容器中。
Her team studied three species of coral from the island of Oahu, in Hawaii. They put them in tanks with either heat stress; more acidic water; or both.
这项研究中真正重要的是温度上升和海洋酸化，因为这正是珊瑚礁正在发生的事情。
Grottoli: And what really matters in this study is the one where both increases in temperature and ocean acidification, because that's exactly what's happening on reefs now.
22个月后，他们评估了赢家和输家。他们发现，平均而言，超过一半的珊瑚存活了下来。即使是在遭受海水变得更温暖、更酸的严重打击后——珊瑚会面临全球变暖低于2度的情况, 珊瑚也会存活下来。
Intagliata: Twenty two months later—they assessed the winners and losers. They found that on average, more than half the corals survived. Even after being punished with warmer, more acidic waters—the kind they'd face under two degrees of global warming.
存活下来的三种瑚中有两种在生理上表现正常。珊瑚不仅仅能正常生存, 对吧?它们正在适应。它们已经适应环境了。它们适应得很好。
Grottoli: The corals that survived, two of the three species were actually physiologically performing normally. They were doing more than surviving. They were coping, they'd acclimatized. They were doing well.
结果发表在《科学报告》杂志上。[Rowan H. McLachlan 等人，基线海水温度和 pH 值发生 22 个月变化后夏威夷珊瑚的生理驯化]
Intagliata: The results appear in the journal Scientific Reports. [Rowan H. McLachlan et al, Physiological acclimatization in Hawaiian corals following a 22-month shift in baseline seawater temperature and pH]
格罗托里表示，这项研究给我们带来了希望，世界上的珊瑚可能比我们想象的更具有适应力，特别是因为他们研究的一种夏威夷珊瑚物种广泛分布在地球上。但这一好消息会促使世界各国领导人遏制气候变暖吗?珊瑚也许可以再等一段时间才能知道答案。
Grottoli says the study provides hope the world's corals may be more resilient than we thought—especially since one of the Hawaiian species they studied is widespread around the planet. But will this good news motivate world leaders to rein in warming? Well, corals may be able to wait just a little longer to find out.
