哥伦比亚冰原上的冰河世纪

Ice Age in Columbia Icefield

如同达芬奇的蒙娜丽莎一样，在加拿大哥伦比亚冰原上，呈现的一张类似蒙娜丽莎的大自然画像，是否也会成为历史的记忆？地球温室效应正在威胁地处北半球一侧的冰川。有一种说法，20年后的哥伦比亚冰原将会消失殆尽。

Columbia Icefeld is the reality of the Cartoon Ice Age.It is the only living fossil of glacial age on earth.Like Mona Lisa of Da Vanci,there is a natural Mona Lisa on the Columbia Icefeld of Canada.Whether it will be the memory of history?Greenhouse effect is threatening the glacier in the northern hemisphere.Another saying is,the Columbia Icefeld will disappear in 20 years.
