Ice collapse will speed up glaciers_资讯
the impact of climate change on the antarctic peninsula is evident in new satellite data, us researchers say. the collapse of the larsen b ice shelf two years ago has accelerated the flow of glaciers into the nearby weddell sea
it is probable the disintegration in 2002 has now allowed the glaciers to deposit their loads more freely, the team tells geophysical research letters
the antarctic peninsula has seen some of the fastest temperature rises on earth in the last five decades.
the scientists used a variety of data from satellites to track the speed of the glaciers before and after the collapse of larsen b.
in one study, ted scambos of the national snow and ice data center in boulder, us, analysed five images taken by the landsat 7 satellite between january 2000 and february 2003.
the analysis reveals that four glaciers flowing into the now collapsed section of larsen b increased in speed by between two and six times over the study period.
"if anyone was waiting to find out whether antarctica would respond quickly to climate warming, i think the answer is yes," said dr scambos.

美国研究者表示，卫星传回的新数据显示，南极半岛的气候变化带来了显著的影响。
两年前崩塌的“守护神b”冰架（巨大的浮动冰层）加快了冰河流入附近的威德尔海的速度。
研究小组对《地球研究快报》（geophysical research letters）表示，可能是因为今年的冰架解体才使得冰河更容易地聚集了能量。
过去的五十年间，南极半岛是地球上气温升高最快的地区之一。
家们使用卫星发回的各种数据来研究"守护神b"冰架崩塌之前和之后冰河流动的速度。
在一项研究中，美国国家冰雪数据中心（位于博尔德市）的特德·斯坎博斯对美国地球资源探测卫星7号在2000年1月和今年2月之间拍摄的五幅图像进行了分析。
分析表明，四条流入“守护神b”冰架现已崩塌部分的冰河在研究期间的流速增加了2至6倍。
斯坎博斯博士说：“如果有人想知道气候变暖是否很快会对南极洲产生影响，我想答案是肯定的。”
