TROMSOE, Norway – An area of an Antarctic ice shelf almost the size of New York City has broken into icebergs this month after the collapse of an ice bridge widely blamed on global warming, a scientist said Tuesday.

挪威，特罗姆瑟--周二，某科学家称有一个南极冰架在本月有大小几乎纽约市的面积破碎成为冰山。之前出现了一次广泛被认为是全球变暖而引起的冰桥坍塌。

The new icebergs added to 330 sq kms of ice that broke up earlier this month with the shattering of an ice bridge apparently pinning the Wilkins in place between Charcot island and the Antarctic Peninsula.

本月稍早已有330平方公里的冰脱离了冰棚，近日这起崩裂又增加了破冰的面积。冰桥塌陷是造成冰棚再次破裂的原因。这座冰桥无疑能将威尔金斯冰棚固定在沙科岛和南极半岛之间。

TROMSOE, Norway - An area of an Antarctic ice shelf almost the size of New York City has broken into icebergs this month after the collapse of an ice bridge widely blamed on global warming, a scientist said Tuesday.

一位科学家周二指出，一块大如纽约市面积的南极冰棚，本月在一段冰桥塌陷后，崩裂成一座座冰山。许多人将冰桥断裂归咎於全球暖化。

The trend is widely blamed on climate change caused by heat-trapping gases from burning fossil fuels, according to David Vaughan, a British Antarctic Survey scientist who landed by plane on the Wilkins ice bridge with two Reuters reporters in January.

据英国南极调查科学家David Vaughan说，这个趋势被广泛地认为是由于燃烧石油产生的温室气体所引起的气候变暖导致。一月份David Vaughan和两位路透社记者乘坐飞机降落在了威尔金斯冰桥上。

The trend is widely blamed on climate change caused by heat-trapping gases from burning fossil fuels, according to David Vaughan, a British Antarctic Survey scientist who landed by plane on the Wilkins ice bridge with two Reuters reporters in January.

英国籍南极洲调查科学家大卫沃恩表示，燃烧化石燃料所产生的温室气体导致气候变异，冰棚消融的趋势普遍被认为与此有关。沃恩於今年一月与两位路透社记者搭机登上威尔金斯冰桥。

It is indicated that characteristic of the seasonal variation of Antarctic sea ice is that the coagulated period is longer than the thaw period.

结果表明，南极海冰的季节变化特点是海冰融化速度远大于凝结速度，而北极海冰融化速度与凝结速度基本相同。

Closer to home, Earth science satellites made a number of key discoveries, such as how waterways beneath an Antarctic ice stream affect sea level and the world's largest ice sheet.

在这一年里，NASA对火星和小行星带启动了空间探测计划，同时，地球卫星也获得了许多重要发现，比如发现南极冰流下的水路如何影响海平面和世界上最大的冰架变化。

They said the movement of a huge stream of ice, about 100km wide and 800m thick, creates seismic waves and can be felt through the entire Antarctic.

数据显示，这块冰流宽约100公里，厚约800米。每次移动时，冰流发出的震波波及整个南极洲。

Moreover, the conclusion was farther validated by ERS-1/DEM gridded 5 kilometers and RADARSAT Antarctic Mapping Project 1km-gridded DEM, tidal noise detected by in situ GPS measurements, and horizontal velocity vector map from RADARSAT SAR images deduced by interferometry method of the whole ice stream.

同时对该地区所在的整个冰流系统用5km分辨率的ERS-1/DEM数据和1km分辨率的RAMP/DEM数据、GPS实地测量数据，以及RADARSAT InSAR速度矢量图等对这一结论进行了深入的验证。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
