These periods of time when large areas of the Earth are covered by ice sheets are called �ice ages.� The last of the ice ages in human experience (often referred to as the Ice Age) reached its maximum roughly 20,000 years ago, and then gave way to warming.

One massive ice sheet, more than 3 kilometres thick in places, grew in fits and starts until it covered almost all of Canada and stretched down as far as Manhattan. Then, 20 000 years ago, a great thaw began. The graph shows 4 major ice ages, on a cycle of roughly 100,000 years. The last ice age peak was just over 20,000 years ago.
