[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
