The Winter That Lasted 300,000,000 Years

Imagine a winter that didn’t last months, or even centuries, but 300 million years. The winter that lasted 300,000,000 years explores the Huronian Ice Age, the longest and most extreme winter Earth has ever experienced. Triggered by the rise of oxygen-producing microbes and the breakup of Earth’s earliest supercontinent, this ancient climate disaster may have frozen the planet nearly solid. Paradoxically, this deep freeze also reshaped life on Earth. It wiped out much of the early biosphere, triggered a massive evolutionary bottleneck, and ultimately helped pave the way for oxygen-breathing life, including humans. What caused this planet-wide freeze? How did life survive it? And could something like it ever happen again? 0:31 - Earth Before Oxygen 2:31 - The Great Oxygen Catastrophe 4:58 - How Kenorland Triggered Global Freeze 7:30 - Earth Becomes a Snowball 10:55 - Why This Ice Age Created Us 13:41 - How the 300 Million Year Winter Ended 16:22 - Could It Ever Happen Again?
