In Episode 2: Snowball Earth, the series explores the catastrophic snowball Earth theory, which proposes that the entire planet was once covered in ice, from the poles to the equator. This extreme event, occurring about 650 million years ago, may have been triggered by a combination of factors, including changes in the Earth's orbit and variations in solar radiation. The episode delves into the evidence supporting this theory, including geological formations and ancient fossils, and examines the potential causes and consequences of such a global glaciation event, highlighting its profound impact on the planet's climate, ecosystems, and the evolution of life.
