You know what kind of weather to expect at each time of year, at least for the place where you live. That's because you're familiar with the climate—the typical range of weather for a region. Did you know that Earth's climate hasn't always stayed the same? Every once in a long while, the Earth goes through a period of especially cold weather called an ice age.

Today, ice covers Earth's North and South poles. These ice caps are called polar glaciers. During an ice age, the polar glaciers grow larger. At the height of an ice age, glaciers may cover as much as a third of the Earth. Canada, the northern United States, northern Europe, and northern Russia all get covered by ice. This ice can be more than a mile (1.6 kilometers) thick.

Much of the world’s water gets frozen to make these glaciers. This water comes from the oceans, and sea level drops as a result. Places that had been under water become dry land. Many plants and animals adapt to these changes. Those that do not adapt die out.

During the last ice age, animals with warm shaggy coats flourished. For example, the woolly mammoth, a large elephant-like animal, roamed icy areas of Earth. The mammoths probably used their huge tusks to scrape away the snow in search of plants to eat. Their thick woolly coats protected them from the cold.

An ice age can last for tens of millions of years. The warm periods between ice ages last hundreds of millions of years.

Earth can warm up somewhat for short periods during an ice age. A warm time within an ice age is called an interglacial. Several interglacials can occur during an ice age. Each one may last for 10,000 years or more.

Ice ages are not like seasons. They do not arrive on any known schedule. In fact, no one can tell when an ice age is beginning. The climate changes very slowly.

The most recent ice age started about 1.6 million years ago. It ended about 10,000 years ago. Or did it? The Earth has warmed up since then, but we may not be between ice ages now. There’s still a lot of ice around the North and South poles, maybe more than there should be between ice ages. Many scientists think we are only in an interglacial period. The ice age may resume sometime in the next few centuries.

Well, now imagine this. The world has found out that the global warming phenomenon will no more haunt this planet. This happens owing to the cooling down of the Earth's temperature rapidly, as though the Sun vanishes. You probably wonder, how can the global warming gets lost that fast? Many scientists have long researches about this, and finally they predict that the temperature will stay cool down for about a month or less. And in that time, the global warming is replaced by a global cooling; a.k.a an ice age. What are you going to do to prepare that age after knowing this?

a. Will commit a suicide.

b. Will freak out and then go crazy.

c. Will buy as many sweaters as you can.

d. Will pray to God so that you'll be saved along the age.

e. Will pray as much as possible so the age doesn't come.

f. Will build an Eskimo's-like house which is warm and anti cold.

g. Your own answer, is 'will…'
