Ancient 'Snowball Earth' Possibly Triggered by Rock Weathering
Inferno Earth or Snowball Earth? Global Warming alarmists tell us we're in a heating cycle that threatens our very existence. Skeptics question what all the fuss is about when we've actually seen cooling over the last 15 years. They're both right... and they're both wrong. Learn the full story here in this infographic!
Earth was a frozen Snowball when animals first evolved
Cryogenian period. Started : 850 mill End : 635 mill.This was the second period of the Neoproterozoic. The name was derived from the Greek word meaning “cold”. During this season the earth saw two major glaciations called the Sturtian and Marinaon that covered the entire earth leading to the snowball earth scenario. This era is sometimes referred to as the Varangian due the glaciations called the Varanger that took place about 800 to 630 million years ago.
Rock weathering may have led to 'Snowball Earth' (Phys.org) —A team of researchers conducting a field study in the Mackenzie Mountains in northwest Canada is suggesting rock weathering almost a billion years ago, may have led to the entire planet being encased in ice for 55 million years. The multi-national teams subsequent analysis of rock samples they retrieved and how doing so led to what they believe is an explanation of one of the most dramatic instances of climate change on record.
