[00:00:30]99% of the Arctic's fresh water ice is in Greenland.

北极地区99%的淡水冰在格陵兰

[00:05:23]It's a staggeringly big ice sheet,

这是块相当巨大的冰原

[00:07:51]but it's just a drop in the ocean

但和南极比起来

[00:09:44]compared to that at the southern end of our planet.

就只是沧海一粟了

[00:22:01]In Antarctica, there is ten times more ice,

南极的冰比北极多十倍

[00:26:00]by far the largest concentration of ice on Earth.

是目前地球上冰量最多的地方

[00:32:05]Our exploration of the Antarctic

我们对于南极的探索

[00:36:48]only began a little over 100 years ago.

始于一百多年前

[00:39:17]The study of ice retreat here was unwittingly begun

关于冰山锐减的研究

[00:49:09]on an expedition led by the great early explorer

始于早期伟大探索家欧内斯特·沙克尔顿

[00:51:55]Ernest Shackleton.

领导的一次不为人知的探险

[00:56:14]In 1916, after their expedition boat was crushed and sunk by ice,

[01:03:19]Shackleton and two companions

沙克尔顿和他的两名同伴

[01:05:21]set off to summon help in a tiny boat.

划了艘小船出去寻求援助

[01:11:57]They sailed over 800 miles across the Southern Ocean

它们在南大洋航行了八百多英里

[01:15:12]to the island of South Georgia, on the edge of the Antarctic.

到达了南极边缘的南乔治亚岛

[01:22:30]Near starving and dressed in rags, the three men

饥肠辘辘 衣衫褴褛的三个人

[01:26:18]walked across the ice sheet at the centre of the island,

穿越过岛中央的茫茫冰原

[01:29:15]knowing there was a whaling base

他们知道

[01:30:45]on the opposite coast where they could summon help.

可以向对面海岸的捕鲸队呼救
