Did you know that we’re still living in an Ice Age that started three million years ago? We just happen to be in the middle of a warm period – luckily for us! Just 20,000 years ago, half of North America was still covered by an ice sheet, and New York was buried under a sheet of ice 1,000 feet thick. These incredible facts and more can all be found in Ice Age. For kids hooked on wild weather, this issue is essential. Want to learn just what causes an Ice Age? Kids will get the details on a range of variables, which include changes in Earth’s orbit around the Sun, the position of land masses, and the levels of carbon dioxide in the atmosphere.
Moving on, explore the fascinating features of the cryosphere, which include the huge and hairy mammals that ruled the Earth during that time – like the saber-toothed cat, which had seven-inch fangs, the wild and woolly mammoths, and six-foot-tall ground sloths. These extraordinary creatures left behind incredibly well-preserved fossils – many of which have been found in Siberia’s frozen tundra. And have you ever wondered what happened to people during the last Ice Age? For kids who like survival stories, an examination of how Neolithic tribes hunted over huge expanses of freezing terrain and drew beautiful pictographs deep inside rocky caves will definitely captivate.
