[00:00:01]The poles are permanently capped with ice.

[00:20:44]the very top of the Earth.
世界之巔
[00:23:43]Up here, it's easy to see
為何極地地區(qū)如此寒冷

[00:29:22]The sun never rises high enough in the sky to warm my back
太陽的直射角度很小 鮮有陽光照射下來
[00:35:11]and those rays that do strike the surface

[00:38:33]are mostly reflected back from this great whiteness.
