[00:00:21]Most of South Georgia's glaciers

自沙克尔顿的时代后

[00:02:20]have shrunk since Shackleton's time

大多数南乔治亚冰川已经消逝了

[00:05:17]and most of that has happened

而且大多数消逝发生在

[00:06:49]since I first went to the Antarctic 30 years ago.

我上次来南极大陆到现在的三十年间

[00:11:55]I've been to South Georgia several times

我来过南乔治亚岛几次

[00:14:06]and seen how greatly the glaciers there have changed.

也见证了这里冰川的剧变

[00:17:08]This photograph of a glacier

照片上的冰川

[00:24:03]reaching right down to the sea

从我1981年第一次来这里起

[00:25:40]was taken just six years

短短六年间

[00:27:50]before I first visited in 1981.

就完全没入了大海

[00:31:51]Now, that glacier has retreated

如今 这片冰川从海边

[00:33:56]by 400 metres away from the beach.

向内陆退后了足足四百米

[00:36:37]Temperatures in South Georgia have risen sharply,

南乔治亚岛的温度急剧上升

[00:45:29]but the Southern Hemisphere's most dramatic warming

但在南半球最显著的气候变暖现象

[00:48:22]has happened a little further south.

发生在更南端的地方

[00:52:23]In recent years, stronger winds blowing over the Southern Ocean

近些年来 渐强的海风吹拂沿南大洋

[00:56:06]have brought warmer air

带来了更暖的空气

[00:57:33]to the 800 mile-long finger of land

吹至八百英里长的狭长陆地上

[01:00:02]that forms the northern extremity of the Antarctic continent.

形成了现在南极大陆北端的样子

[01:09:45]Here, on the Antarctic Peninsula,

在过去五十年里

[01:12:50]the changing wind patterns have driven

海风的变化

[01:14:45]temperatures up by nearly three degrees Centigrade

使南极半岛的气温

[01:17:54]over the last 50 years.

上升了近三摄氏度

[01:19:03]Ten times the average rate of the rest of the planet.

这是地球其他地区平均水平的十倍
