Let's start with the Antarctic ice sheet.

先从南极冰原说起。

28. What does the latest information reveal about the West Antarctic ice sheet?

问题28. 最新的信息揭露了南极西部冰盖的什么？

More likely, at least in the short term, is the collapse of the West Antarctic ice sheet.

更加可能的是，至少在短期内，南极洲西部的冰盖会塌陷。

But they are not isolating the Antarctic Peninsula and parts of the Western Antarctic ice sheet that lie directly in their path.

但这些风并没有孤立在其路径中间的南极半岛和南极冰盖西部的部分地区。

As Herman Ankleherd, a co-author from Californian Institute of Technology says, " The West Antarctic ice sheet disappeared once and can disappear again."

来自加州理工学院的赫尔曼·安科赫尔德，同时也是此书的合著者说：“如果南极西部冰盖曾经消失过一次，那么现在完全可能再次消失。”

“The West Antarctic ice sheet disappeared once and can disappear again.”

“南极西部冰盖曾经消失过，也可能再次消失。”

Scientists agree that they key player in this scenario is the West Antarctic ice sheet.

科学家们一致认为， 他们在这种情况下的关键角色是南极西部冰盖。

Most of that’s found in the Greenland and Antarctic ice sheets .

其中大部分存在于格陵兰岛和 南极冰盖中。

Scientists agree that the key player in this scenario is the West Antarctic ice sheet. A Brazil-size mass of frozen water that is much as 7,000 feet thick.

科学家说这场灾难的关键是南极洲西部冰原，如同巴西大小的冷冻冰块足有7000英尺厚。

Candidate sites included tropical corals in the US and Australia, a mountainous peat bog in Poland, the Antarctic ice sheet and even the human debris accumulated under the city of Vienna.

候选地点包括美国和澳大利亚的热带珊瑚、波兰的山区泥炭沼泽、南极冰盖，甚至是维也纳市下面堆积的人类残骸。

The Greenland ice sheet, the West Antarctic ice sheet, abrupt thawing of permafrost, losing all tropical coral reef systems and collapse of the Barents Sea ice.

格陵兰冰盖、西南极冰盖、永久冻土突然融化、所有热带珊瑚礁系统消失以及巴伦支海冰层崩塌。

He said of the JPL study, " if we keep to the 2 degrees of global warming that the Paris agreement promises, the sea level rise due to the East Antarctic ice sheet should be modest."

他在谈到喷气推进实验室的研究时说，“如果我们坚持《巴黎协定》所提出的将全球变暖控制在2摄氏度以内的承诺，那么由东南极冰盖造成的海平面上升幅度应该不会太大。”

If the Atlantic overturning is weakening, leaving heat behind in the Southern Ocean and heating up of the Southern Ocean is the biggest threat factor for the Antarctic ice sheets.

- 如果大西洋倾覆正在减弱，那么南大洋就会留下热量，南大洋升温是南极冰盖的最大威胁因素。

Siegert added that if the event had happened during the Antarctic summer, instead of winter, it would have caused melting on the surface of the East Antarctic ice sheet, which has so far been saved from melting.

西格特补充说，如果这一事件发生在南极的夏季，而不是冬季，它将会导致南极东部冰盖表面融化，到目前为止，南极东部冰盖还没有融化。
