BBC紀(jì)錄片《冰凍星球》履于薄冰第19期:冰雪流失

[00:00:01]The remainder of the Wilkins 威爾金斯的剩余部分 [00:02:15]looks set to break apart soon. 好似即將分崩離析 [00:04:41]It's the latest ice shelf 一道洋流向南漂流 [00:10:04]to disintegrate in a wave that's been travelling southwards, 一路上使新近形成的冰架破裂 [00:13:55]playing a major role in the loss of ice from the Peninsula. 這種作用是造成半島冰雪流失的主要原因 [00:19:19]Next in line, and already weakening in places, are the ice shelves 接下來(lái)便輪到已很脆弱的冰架 [00:24:07]that hold back Antarctica's gigantic continental ice sheet. 這些冰架可防止南極巨大的冰原滑入海中 [00:28:53]And it would only take a small corner of this 每次崩裂的只是冰原一角 [00:32:24]to slide into the sea 不知不覺(jué)陷入大海 [00:34:12]to have major global consequences. 卻能帶來(lái)嚴(yán)重的全球效應(yīng) [00:36:26]We've only started to see 我們最近才剛看到 [00:41:23]changes in the Arctic and Antarctic recently. 北極和南極的變化 [00:44:32]So, it's hard to predict exactly 所以很難準(zhǔn)確預(yù)言 [00:46:17]what impact these changes will have. 這些改變帶來(lái)的影響 [00:48:52]But we can see for ourselves that these places are changing 但我們正目睹這些地區(qū)的改變 [00:52:48]and on a scale that is hard to ignore. 其規(guī)模無(wú)法忽視 [00:58:27]The Poles, North and South, may seem very remote, 南北兩極看似地處偏遠(yuǎn) [01:03:11]but what is happening here 但這里發(fā)生的事情 [01:05:11]is likely to have a greater effect upon us 對(duì)我們產(chǎn)生的影響 [01:08:41]than any other aspect of global warming. 可能遠(yuǎn)大于全球變暖的其他方面 [01:12:17]If the Arctic sea ice continues to disappear, 如果北極海冰繼續(xù)融化 [01:15:32]it will drive up the planet's temperature more quickly. 地球氣溫升高的速度會(huì)更快 [01:19:09]And the melting ice sheets 到本世紀(jì)末 融化的冰原 [01:20:31]could contribute to a sea level rise of a metre, 能使海平面上升一米 [01:23:55]enough to threaten the homes of millions of people 足以威脅全世界沿海地區(qū) [01:27:06]around the world's coasts by the end of the century. 數(shù)百萬(wàn)人的家庭 [01:32:06]We've seen that the animals 我們看見(jiàn) [01:33:37]are already adapting to these changes, 動(dòng)物已經(jīng)在適應(yīng)這些變化 [01:36:24]but can we respond to what is happening now to the frozen planet? 但我們能對(duì)冰凍星球的現(xiàn)象作出響應(yīng)嗎
