Earth's Orbit and Tilt Linked to Ice Age Cycles, Next One Delayed by Climate Change
Scientists have discovered a strong link between Earth's tilt and past ice ages, predicting the next glacial period would have started in 11,000 years. However, rising greenhouse gas emissions are disrupting these natural cycles. The research, based on ocean sediment data, supports the theory that Earth's obliquity governs ice expansion while prece...

Storm Of Fire, Ice Led To 'Snowball Earth' 700 Million Years Ago
A perfect combination of erupting volcanoes along with a rapid cooling effect may have caused the largest glaciation event in history - known as 'snowball Earth' - that covered our planet pole-to-pole in ice more than 700 million years ago, Harvard scientists say.

Decreased Carbon Dioxide Formed Antarctic Ice Sheet?
Turning a long-held climate shift theory on its head, researchers have found that decreased carbon dioxide (CO2) levels during a major climate shift 34 million years ago led to initiation of Antarctic glaciation.
