700 Million Years Ago, Earth’s Oceans Plunged to Near-Freezing in Snowball Earth Era
During the Cryogenian Period, Earth experienced one of its most extreme ice ages — a global “Snowball Earth” event — when oceans may have reached near-freezing temperatures and ice sheets spread from the poles to the equator.
Key Facts:
Geological evidence shows glacial deposits near the equator, indicating extreme global cooling.
Ocean temperatures likely approached 0 °C, severely limiting marine life and ocean circulation.
Causes include low atmospheric CO₂ and extensive rock weathering, allowing temperatures to collapse globally.
Expert Insight:
Snowball Earth events demonstrate the planet’s climate extremes and resilience, shaping the evolutionary trajectory of early life and modern climate understanding.
