BBC紀(jì)錄片《冰凍星球》履于薄冰第14期:氣候變暖

[00:00:21]Most of South Georgia's glaciers 自沙克爾頓的時(shí)代后 [00:02:20]have shrunk since Shackleton's time 大多數(shù)南喬治亞冰川已經(jīng)消逝了 [00:05:17]and most of that has happened 而且大多數(shù)消逝發(fā)生在 [00:06:49]since I first went to the Antarctic 30 years ago. 我上次來南極大陸到現(xiàn)在的三十年間 [00:11:55]I've been to South Georgia several times 我來過南喬治亞島幾次 [00:14:06]and seen how greatly the glaciers there have changed. 也見證了這里冰川的劇變 [00:17:08]This photograph of a glacier 照片上的冰川 [00:24:03]reaching right down to the sea 從我1981年第一次來這里起 [00:25:40]was taken just six years 短短六年間 [00:27:50]before I first visited in 1981. 就完全沒入了大海 [00:31:51]Now, that glacier has retreated 如今 這片冰川從海邊 [00:33:56]by 400 metres away from the beach. 向內(nèi)陸退后了足足四百米 [00:36:37]Temperatures in South Georgia have risen sharply, 南喬治亞島的溫度急劇上升 [00:45:29]but the Southern Hemisphere's most dramatic warming 但在南半球最顯著的氣候變暖現(xiàn)象 [00:48:22]has happened a little further south. 發(fā)生在更南端的地方 [00:52:23]In recent years, stronger winds blowing over the Southern Ocean 近些年來 漸強(qiáng)的海風(fēng)吹拂沿南大洋 [00:56:06]have brought warmer air 帶來了更暖的空氣 [00:57:33]to the 800 mile-long finger of land 吹至八百英里長(zhǎng)的狹長(zhǎng)陸地上 [01:00:02]that forms the northern extremity of the Antarctic continent. 形成了現(xiàn)在南極大陸北端的樣子 [01:09:45]Here, on the Antarctic Peninsula, 在過去五十年里 [01:12:50]the changing wind patterns have driven 海風(fēng)的變化 [01:14:45]temperatures up by nearly three degrees Centigrade 使南極半島的氣溫 [01:17:54]over the last 50 years. 上升了近三攝氏度 [01:19:03]Ten times the average rate of the rest of the planet. 這是地球其他地區(qū)平均水平的十倍
