And now we have Tierney's new results on the temperature difference between glacial and interglacial conditions.

现在我们还掌握蒂于冰期和间冰期之间的温差研究的新结果。

They moved into the area during warm periods, called interglacial periods.

他们在温暖的时期进入该地区，称为间冰期。

The end of the Ice Age saw a world that was melting away.

在冰期末期整个世界冰消雪解。

Even less well understood are the cycles of comparative balminess within ice ages, known as interglacials.

对于一个冰川期内被称为间冰期的一段气候相对暖和的时期，我们对其周期尤其解。

The end of the Ice Age set off a major movement of species.

The records show cold years with long stretches of early ice, warm years with less.

记录显示，寒冷的年份会有一个较长时间的早期冰期，而温暖的年份的则相对较短。

The other Great Lakes' ice seasons are shrinking as well, by an average of about half a day per year.

其他五大湖的冰期也在减少，平均每年减少约半天。

We're coming to the end of the Pleistocene, the end of the Ice Age.

Within that, you have cycles of “glacial periods” and “interglacial periods”.

其中，你有“冰期” 和“间冰期” 的循环。

To answer that, we have to go back to the mighty ice age glaciers that covered almost half the continent.

为回答这一问题，我们需要回到冰河时代，看看覆盖半片大陆的大冰期冰川。

But geologists call it the Last Glacial Maximum.

但地质学家称之为末次盛冰期。

Laying 30 meters below the opening in an underground cavern, they found the remains of thousands of ice age mammals.
