冰冻星球（2011）

..而另一个较低的山脉，靠近西海岸，
..whilst another lower range, nearer the west coast,
防止雨水从太平洋流入
prevents rain coming in from the Pacific Ocean.
这在它们之间创造了最干燥的地区之一
This creates, between them, one of the driest
地球上的高海拔沙漠...
high-altitude deserts on Earth...
..阿塔卡马沙漠
..the Atacama.
然而，这里有一个湖--
There is, nonetheless, a lake here -
充满咸水的火山
a volcanic one that is filled with extremely salty water
从地下
from underground.
这吸引了火烈鸟
And this attracts flamingos.
它们每年夏天都会来这里
They come here each summer.
它们在这里筑巢养育它们的幼鸟，
And here they nest and raise their young,
利用湖中丰富的藻类
taking advantage of the lake's plentiful algae.
但随着冬天的到来，
But with the arrival of winter,
晚上的温度降到零度以下...
temperatures at night drop to below freezing...
..即使是这些顽强的鸟类也无法长♥期♥忍♥受的气温条件
..conditions that even these hardy birds cannot endure for long.
成年鸟开始离开并前往温暖的地方
The adults start to leave and head for warmer temperatures
下山
lower down the mountain.
但它们留下了四个月大的幼鸟，
But they leave behind their four-month-old chicks,
幼鸟已经大到可以养活自己
which are old enough to feed themselves
但还没有强大到可以飞起来
but not yet strong enough to fly.
每过一个晚上，气温就会继续下降
With each passing night, temperatures continue to fall.
然后，一个早晨，在一个特别寒冷的夜晚之后，
And then, one morning, after a particularly cold night,
幼鸟们发现自己被冰包围了
the chicks find themselves surrounded by ice.
挤在一起可以让一些人保持宝贵的体温
Huddling together allows some to preserve precious body heat.
但是外面的鸟
But those on the outside
更加暴露
are left even more exposed.
有些鸟已经无法忍♥受冰冻的温度条件
And some have already succumbed to the freezing conditions.
咸冰现在这么冷
The salty ice is now so cold
它凝结在幼鸟的羽毛上
that it congeals on the chicks' feathers.
重负荷之下，幼鸟飞翔的机会就更加渺茫了
Weighed down, their chances of flying are even more remote.
现在时速 40 英里的风掠过湖面，
Now 40mph winds whip across the lake,
气温进一步降低
driving down temperatures even further.
然而，这风可以杀死它们
Yet this very wind that could kill them
也可能是它们的救星
might just be their saviour.
年轻人转身面对风
The youngsters turn to face it.
如果它们能恰到好处地抓住它，它可以给它们
If they can catch it just right, it could give them
它们第一次飞行所需的上升力
the lift they need to take their very first flight.
对于那些背负着沉重冰块的人...
For those encumbered with heavy loads of ice...
..努力几乎太多了
..the struggle is almost too much.
终于自♥由♥了
Freedom at last.
许多生活在冰冻的山峰之间的动物
Many animals that live amongst the frozen peaks
几千年来已经适应了
have over thousands of years become adapted
面对高海拔生存的挑战
to meet the challenges of a high-altitude existence.
但现在它们的世界正在改变
But now their world is changing
因为全球变暖
because of global warming.
在高山冰川深处仍然结着的冰
Ice that has remained frozen deep within mountain glaciers
开始融化了...
is starting to melt...
..加速它们的运动
..accelerating their movement.
在拍摄这个系列的三年时间里，
Over the three years that it took to film this series,
秘鲁安第斯山脉海拔 5,500m 的 奎尔卡亚 冰盖，
the Quelccaya Ice Cap, 5,500m up in the Peruvian Andes,
后退了惊人的60米
has receded by a staggering 60 metres.
在欧洲，一些高山冰川现在正在缩小
In Europe, some alpine glaciers are now shrinking
每年100米
by 100 metres a year.
其中之一 --瑞士的圣安纳菲尔冰川--
One of them - the Sankt Annafirn Glacier, in Switzerland -
几乎完全消失了
has almost completely disappeared.
预计其它大多数山都会象它一样
Most of the others are expected to have followed it
到世纪之交
by the turn of the century.
冰冻山坡的变暖可能会威胁到动物的生命
The warming of the frozen slopes could threaten the life of perhaps
最著名的山地居民
the most famous mountain resident of all.
隐藏在中国西部的竹林中...
Hidden within the bamboo forests of western China...
..这是一只烦躁不安的雄性大熊猫
..is a hot and bothered male giant panda.
它整个冬天都躲在山谷的低处
He has spent the winter sheltering lower down the valley.
现在是初夏，
Now it's early summer,
它整个冬天保护它的厚外套
and his thick coat that protected him throughout the winter
变得非常不舒服
has become very uncomfortable.
它需要到达更高处，冷一点的山坡
He needs to reach the cold of the higher slopes.
但在它开始攀登之前，
But before he can start the ascent,
它需要一顿美餐来给它必要的能量
he needs a good meal to give him the necessary energy.
大熊猫除了竹子几乎什么都不吃
Giant pandas eat almost nothing except bamboo.
但是竹子的热量太低了
But bamboo is so low in calories
它每天需要花十个小时吃饭
that he needs to spend ten hours a day eating.
吃完早餐...
With breakfast over...
..它开始爬到更高的地方
..he begins his climb to higher ground.
但一时之间...
But in no time at all...
..它又饿了
..he's hungry again.
这将是一段漫长的旅程
This is going to be a long journey.
在不久的将来，它可能会更长
And it may be an even longer one in the near future.
随着气候变化使这些山脉的温度升高，
As climate change raises the temperature in these mountains,
大熊猫可能需要爬得越来越高
giant pandas may well need to climb higher and higher
寻找更凉爽的条件
to find cooler conditions.
但它们最喜欢的清凉竹子
But the cold-loving bamboo they most favour
不能这么轻易移♥动♥...
cannot move so easily...
..并且可能完全从温暖的较低斜坡上消失
..and may disappear from the warmer lower slopes altogether.
到目前为止，这些白雪皑皑的山峰继续提供
So far, these snow-covered peaks continue to provide
这个雄性有足够的空间来觅食和寻找配偶
this male with enough space to feed and find a mate.
于是，它以熊猫式的气味标记了它的领地--
so, he scent-marks his territory panda-style -
倒立
with a handstand.
很可能在接下来的几十年里
It may well be that in the next few decades
世界的大山将变暖
the mountains of the world will warm.
如果发生这种情况，许多物种将不可避免地消失
Should that happen, many species will inevitably disappear.
但我们永远不应该忘记这些多能力的、有忍♥耐力的
But we should never forget the versatility and endurance
--成功居住的动物...
of the animals that have succeeded in colonising...
..和这些天空中的冰冻岛屿
..these icy islands in the sky.

冰冷之外
在冰封的山峰，团队最大的挑战
In the frozen peaks, the team's greatest challenge
是第一次在晚上拍摄一只成功的美洲狮狩猎
was to film a successful puma hunt at night for the first time.
摄制组在严冬前往巴塔哥尼亚
The crew travelled to Patagonia in the depths of winter
前往拥有 200 多只美洲狮的 托雷德佩恩山(智利)，
to Torres del Paine, home to over 200 pumas,
地球上美洲狮密度最高的地方
the highest density on Earth.
在这偏远的荒野中依然找到它们，面♥积♥很大
Still, to find them in this remote wilderness
比伦敦还大，
greater than the size of London,
他们聘请了当地的美洲狮专家 Diego Araya，
they joined the local puma expert, Diego Araya,
--有超过 20 年追踪这些大型猫科动物的经验
who has over 20 years' experience of tracking these big cats.
这对我们来说是全新的，
This is something completely new for us,
因为我们从来没有真正跟踪过大猫
because we've never been actually in pitch-black following cats.
并且能够步行跟上它
And being able to keep up with it on foot
我认为这将是一项令人难以置信的任务
I think is going to be an incredible task.
这个遥远的南方，在南美洲的顶端，
This far south, at the tip of South America,
冬天只有九个小时的白天
winter only gives them nine hours of daylight
在夜幕降临之前找到美洲狮
to find the pumas before night descends.
但没过多久，他们就有了一次意外的相遇
But it's not long until they are treated to a surprise encounter.
当然，我们不是你菜单的一部分，对吧？
Definitely, we are not part of the menu, huh?
与野生美洲狮近距离接触是一种难得的特殊机会
Getting this close to a wild puma is a rare privilege
女摄影师 海伦霍宾
for camerawoman Helen Hobin.
这是非常超现实的，在现实生活中看到一只美洲狮
It's very surreal, actually, being in real life and seeing one.
白天，这些经过充分研究的美洲狮是平易近人的
By day, these well-studied pumas are approachable.
但随着黄昏降临，美洲狮加快了步伐
But as dusk descends, they pick up the pace
当美洲狮切换到狩猎模式时
as they switch to hunting mode.
我们很快就会进入漆黑的，
We're just going into the pitch-black pretty soon,
我们必须依靠热能来度过余下的夜晚
and we have to rely on thermal the rest of the night.
配备最先进的热成像相机
Armed with a state-of-the-art thermal-imaging camera
并发现范围，他们试图跟随
and spotting scopes, they attempt to follow
漆黑中的美洲狮
the puma in the pitch-black.
大猫们现在移♥动♥得这么快，
The cats are moving so fast at the moment,
它们可以覆盖数英里
and they can cover miles.
用我们所有的设备很难跟上，
It's quite hard to keep up, with all of our equipment,
而不是真的能够看到你要去哪里
and not really being able to see where you're going.
几个小时后，美洲狮避开了他们
A few hours later, and the pumas have given them the runaround.
你看到山上的热信♥号♥♥了吗？
You see a heat signal on the hill?
你看见它了吗？
Do you see her?
