An Ice Age Every 100,000 Years: Why? See 122,000 Year Simulation Of Ice Sheets

Science struggled to explain fully why an ice age occurs every 100,000 years. As researchers now demonstrate based on a computer simulation, not only do variations in insolation play a key role, but also the mutual influence of glaciated continents and climate. During the last ice age northern regions of America, Europe and Asia were covered under thick ice sheets. (Illustration: Ittiz / Wikipedia) Ice ages and warm periods have alternated fairly regularly in the Earth’s history: the Earth’s climate cools roughly every 100,000 years, with vast areas of North America, Europe and Asia being buried under thick ice sheets.
