全球变暖的警示：太空拍摄冰川移动奇观

冰川就是在陆地表面缓慢移动的巨大冰块，它雕刻出美轮美奂的景观。但是冰川对任何气候变化都极为敏感，它们是全球气候变暖的信号。这里为您呈现的是人造卫星和宇宙空间站的宇航员抓拍到的冰川移动奇观。

The Bear Glacier in the Kenai Peninsula along the Gulf of Alaska empties into a lake. Pieces of the glacier that have broken off look like shards of white glass in the blue water. Down the middle of the glacier run dark gray ?racing stripes.? As a glacier

位于基奈半岛上的大熊冰川（Bear Glacier）沿着阿拉斯加湾而下，最终流入到一个湖内。漂浮在湛蓝湖水中的冰川碎片看上去就像是白色的碎玻璃。冰川中间的流线型条纹是由冰川在移动过程中夹带的泥土和岩屑形成的。

The Erebus glacier in Antarctica comes down from Mt. Erebus and protrudes off the coast of Ross Island, forming an 11-12 km long ice tongue?a long and narrow sheet of ice projecting out from the coastline

从南极洲埃里伯斯山（Mt Erebus）缓慢而下的厄瑞玻斯冰川（Erebus glacier）伸向罗斯岛海岸，形成了一条长11-12公里的冰舌：一条沿着海岸线的狭长冰带。

Like a river of ice, the Byrd Glacier plunges through a deep, 15-mile-wide valley in the Transatlantic Mountains of Antarctica to create a 100-mile-long, rock-floored ice stream

疑似冰河落九天！南极洲的伯德冰川（ Byrd Glacier ）飞流直下落入到跨大西洋山脉一个15英里宽的深谷中，创造出了一条100英里长、以岩石为河床的冰河奇观。

Several glaciers are seen above Dobbin Bay in the Canadian Arctic on Ellesmere Island...

加拿大北极地区，埃尔斯米尔岛的多宾湾被数个冰川所覆盖......

...A more detailed view of the leading edge of the Eugenie Glacier's 'floating tongue' reveals surface cracks and extensive calving of icebergs in Dobbin Bay

......多宾湾内，近景观察吉尼冰川（Eugenie Glacier）那条"漂动舌头"的最前端，你会发现冰山表面的裂纹和大面积崩解的迹象。

The Bering Glacier, about 10 km from the Gulf of Alaska, is the largest glacier in North America. Warmer temperatures and changes in precipitation over the past century have thinned it by several hundred metres

源于阿拉斯加湾的白令冰川（Bering Glacier）绵延10公里，是北美最大的冰川。但在过去一个世纪里，气候变暖和降水量的变化已经使得白令冰川缩短了几百米。

The Heiltskuk Icefield covers about 1,389 square miles of British Columbia. This astronaut photo shows two major valley glaciers: large masses of slowly flowing ice and entrained debris that move downhill, carving out wide valleys

加拿大西部的不列颠哥伦比亚省的 Heiltskuk 冰原面积达1389平方英里。这张由宇航员拍摄的照片展示了两个主要的山谷冰川：几处缓慢流动的巨大冰块和被冰川夹带着沿坡而下的碎屑，勾勒出广阔的山谷景观。

The Southern Patagonian Icefield of Chile and Argentina hosts several spectacular glaciers, including Grey Glacier which terminates in three distinct lobes into Grey Lake

智利和阿根廷的南部巴塔哥尼亚冰原（Southern Patagonian Icefield）汇集了数个奇特壮观的冰川，其中包括了格雷冰川（Grey Glacier，即灰色冰川），它最终分成三个不同分支汇入到格雷湖中（Grey Lake）。

This image shows the eastern margin of the Greenland Ice Sheet. The ice sheet margin appears pale blue-gray, which may be a sign it is saturated with water

这张照片展示的是，格陵兰冰盖（Greenland Ice Sheet）东部边缘。冰盖边缘是灰色的，这可能是冰川融化的一个信号......

...a more detailed view shows deeper blue pools of melt water dotting the ice sheet's surface

近景观察发现，冰盖表面点缀着多处已经融解的深蓝色湖。

The Expedition 3 crew of the International Space Station caught a rare glimpse of the massive ice fields and glaciers of Patagonia early in the afternoon on September 25, 2001

2001年9月25日中午过后，国际空间站"远征者3号"的全体工作人员看到了罕见的一幕：巴塔哥尼亚巨大的冰原和冰川地带。

Glacial lakes in the Bhutan-Himalaya suggest that glaciers in the Himalaya are wasting at alarming and accelerating rates

喜马拉雅-不丹境内有许多冰川胡，这意味着喜马拉雅冰川正以令人震惊的加速度融解。

Streamers of dust - fine sediments produced by glaciers grinding down the mountains - are blown out over the Gulf of Alaska

吹过阿拉斯加湾的尘土带——这是冰川碾磨底部山脉形成的细颗粒泥沙。

The Pasterze Glacier in western Austria has been receding since 1856. A combination of higher summer temperatures and lower winter snowfall is causing the retreat
