How is ice ages are related to changes in the atmosphere?
There is evidence that greenhouse gas levels fell at the start of ice ages and rose during the retreat of the ice sheets, but it is difficult to establish cause and effect. Greenhouse gas levels may also have been affected by other factors which have been proposed as causes of ice ages, such as the movement of continents and volcanism. ChaCha!

About Greenhouse Gas
Greenhouse gasses are gasses that trap heat and infrared radiation in the atmosphere. On Earth they include water vapor, methane, nitrous oxide, carbon dioxide and ozone. Even with the level of greenhouse gasses in our atmosphere rising, at least we don't look like Venus with temperatures in the 400 - 800 degree Fahrenheit range.
