与此同时，北半球进入夏季，南极倾斜远离太阳，南半球已开始感受到冬天的寒冷。
At the same time that the Northern Hemisphere is entering summer, the South Pole is tilted away from the sun, and the Southern Hemisphere is starting to feel the cold of winter.
根据日本的研究，在80年代和90年代之间，南半球的南极鲸数量急剧下降。
Japanese studies showed that the Numbers of Antarctic minke in the Southern Hemisphere appeared to drop significantly between the 1980s and 1990s.
这些气球在使用前都要经过加热出来，以恢复弹性。即使是南半球的夏天，南极站附近的温度也只有-4华氏度(- 20摄氏度)，气球都会冻得失去弹性。
The balloons must first be heated to regain their elasticity, which is robbed from them in storage by the -4 degrees Fahrenheit surface temperatures in the southern hemisphere's summer.
虽然南半球也见证着类似的融冰影响，但是格陵兰冰盖恐怕尤其易受损伤的，因为比起南极洲冰盖，它距寒冷的极地要远得多。
While similar melting effects are being measured in the southern hemisphere, the Greenland sheet may be uniquely vulnerable, lying much further from the chill of the pole than Antarctica's sheets.
南半球的每个春季和夏季，当太阳升起，24小时照耀在南极洲的天空上时，罗斯海也焕发了生命。
Every southern spring and summer, after the Sun has risen into its 24-hour circuit around the skies of Antarctica, the Ross Sea bursts with life.
每逢南半球春季，南极洲平流层中都会出现不祥的臭氧层空洞。
Every austral spring, an ominous "hole" appears in stratospheric ozone over Antarctica.
气温也会变冷，尽管是在南半球的春季环境下航行，但是来自南极洲的冰盖的冷风也有可能直接吹过来。
It'll be chilly, too, because although it will be a Southern Hemisphere spring, the wind might be coming straight up from the ice of Antarctica.
地球仪显示，水在整个南半球占绝对优势势—包括大西洋和太平洋最广阔的部分以及环抱地球的南极海洋。
The globe shows that the entire southern hemisphere is preponderantly water—the widest parts of the Atlantic and Pacific, the unbroken sweep of Antarctic seas circling the world.
南极海冰作用区约占南半球雪冰作用区面积的58%，约占地球表面积的3.58%。
The area of Antarctic sea ice takes about 58% of all the area of south hemisphere cryosphere, and 3.58% of Earth surface area.
我要补充一点，我们很难想象一个几何物体只能从南极那里观看到，应该是整个南半球都能看到才符合理论依据！
I should add that it is impossible to imagine a geometry in which an object can be seen only from the South Pole.
在南半球，它的所谓南极光，或是南部灯。
In the southern Hemisphere, it's called aurora australis, or southern lights.
