由于强烈的厄尔尼诺现象导致了海水变得异常温暖,冰层消失了,而南极洲的上万只帝企鹅被迫离开繁殖地,再也没有回来过。

Disappearing Sea Ice Forces Penguins to Move

南极洲的帝企鹅栖息地缩水

Up until 2016, Antarctica’s Halley Bay was the second-largest breeding ground for emperor penguins and then in one year, they were gone.Between 15 and 24 thousand birds and they haven’t been back since. Researchers with the British Antarctic Survey soon found out why.The sea ice on which the penguins breed and raise their chicks have blown out, disappeared.The ice disappeared due to a strong El Nino that causes unusually warm waters, but what happened to all those penguins.

在2016年之前,南极洲的哈雷湾是帝企鹅的第二大繁殖地,但一年后,企鹅们就消失了。大约有一万五千只到两万四千只鸟从那以后就再也没有回来过。英国南极调查局的研究人员很快就找到了原因。企鹅需要从中繁殖后代的海冰消失了,由于强烈的厄尔尼诺现象导致了海水变得异常温暖,冰层消失了,但是企鹅到底怎么样了呢。

We’ve been seeing the colony at Halley Bay getting smaller and smaller, even the adults, but another colony about 30 miles to the South has been growing and about maybe over half of the adults now have bulked and left Halley Bay and started to breed at this colony 30 miles to the South.

我们已经看到了在哈雷湾殖民地变得越来越小,甚至对成年企鹅来说也是这样,但在向南约50英里有另一个殖民地,也许现在超过一半的成年企鹅都大批地离开哈雷湾了,开始在这个殖民地以南30英里的地方另外繁衍生息。

Fred Well says this is good news because it suggests penguins are adapting to a rapidly changing climate and they’re going to need to keep adapting.Well then we can say we predict that the climate change, El Nino events will get stronger and we’ll get more storm events. And it’s not just Halley Bay that’s melting.This entire part of the continent is at risk.We’re all seeing the Antarctic peninsular is rapidly warming, not the whole Antarctic but one particular area is warming,ice loss in many areas and we’re seeing, we’re predicting storm events and El Ninos are going to get bigger.If these warming events keep happening, studies suggest the world population of emperor penguin could decline by as much as 20% the century.

弗雷德·威尔说这是个好消息,因为这表明企鹅正在适应快速变化的气候,它们需要不断适应。那么我们可以说,我们预测气候变化,厄尔尼诺现象会变得更强,我们会看到更多的风暴事件。而且不仅仅只有哈雷湾在融化,整个南极洲大陆都处于危险之中。我们都看到南极半岛正在迅速变暖,不是整个南极,而是一个特定的地区在变暖,很多地区的冰都在融化,我们预测风暴和厄尔尼诺现象将会变得更大。如果这些变暖事件继续发生,研究表明,帝企鹅的世界数量可能在本世纪最多减少20%。
