Hints:

Ice Age

If the earth gets hotter in the new century, what will happen to animals and the plants which animals depend on for survival? The question offers another way of looking at the greenhouse effect. People have talked about the general problem of global warming for some time. But they were usually worried about things like whether to buy a home on the coast. Biologists and other scientists turn their attention to plants and animals at an important meeting that took place last October. They reviewed evidence that plants and animals are sensitive to climate. Since the Ice Age ended 10,000 years ago and warmer temperatures returned to the northern latitudes, many species have migrated north.
如果在新世纪里地球变暖更为严重了，那么动物和它们赖以生存的植物会怎样呢？这个问题提供了另一种看待温室效应的方式。人们探讨温室效应问题已经有一段时间了，但是他们通常都是在担心要不要在海边买房子之类的问题。在去年十月的一次重要会议上，生物学家和其他科学家将注意力放在了动物和植物上面。他们审视了关于动植物更容易被气候影响的证据。自从一万年前的冰河世纪结束之后，北方地区气温回暖，很多物种向北方迁徙了。
