如果地球与太阳的距离再大1%，大约20亿年前地球上失控的冰期就会导致海洋冻结，并一直冻结到今天。
If the Earth-Sun distance were as little as 1 percent larger, runaway glaciations on Earth about 2 billion years ago would have caused the oceans to freeze and remain frozen to this day.
研究人员对间冰期气候的线索来自保存在GRIP 冰芯中的两种略微不同类型的氧——即同位素氧-16和氧-18的比率。
Researchers' clues to the Eemian climate come from measurements of the ratios of two slightly different types of oxygen, isotopes oxygen-16 and oxygen-18, preserved in the GRIP core.
我们的祖先以令人眼花缭乱的机会主义，适应了自上一个大冰期结束后，约1万年前普遍但不规则的全球变暖。
Our ancestors adapted to the universal but irregular global warming since the end of the last great Ice Age, around 10,000 years ago, with dazzling opportunism.

在最后一个冰期期间，他们了解到海平面的下降偶尔会产生横跨海峡的陆桥。
They knew that every so often during past ice ages, drops in sea level created a land bridge across the strait.
研究者表明：“长毛象以及其他一些大型的冰期动物的灭绝不应归咎于‘人类的袭击’。”
The extinction of the woolly mammoth and other large ice age animals can't be blamed on a 'human blitzkrieg', say researchers.
航行船只局限于小船，即使在短短夏季数月的无冰期，通行起来也足够困难。
Navigation was confined to shallow vessels, tricky enough even in the few summer months when the river was free of ice.
一开始，这么做仅仅只是为了驱走天气的寒冷，那时世界刚刚进入大冰期时代。
At first, this was merely for function: to keep out the cold weather of the world only beginning to emerge from the great ice age.
