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.
