Ice age does not just ice up the poles but
drops the temperatures everywhere around the world by about ten
degrees centigrade. The effects are so dramatic.
The world's wildlife gets squeezed into a band near the equator
and even here life is hardly comfortable. The vast polar ice packs
lock up a lot of the earths's water, disrupting rainfall and turning
previously lush tropical areas into drought-stricken deserts.
