Now it's really hard to grasp the scale of these places, because as the glaciers -- one of the things is that places like Alaska and Greenland are huge, they're not normal landscapes -- but as the glaciers are retreating, they're also deflating, like air is being let out of a balloon.
现在已经很难掌握这些地方的规模了 因为这些冰川-- 要知道像阿拉斯加和格陵兰是很大的地方， 他们有着不一般的地貌-- 冰川消退时，也在浮动， 像空气从气球里放出来一样。
