Episode 252 - The Ice Age

Episode 252 - The Ice Age13 sep2 u 11 min

About 10% of the Earth’s land surface is currently covered in persistent glacial ice, but for most of Earth history, that number was much closer to zero. This episode, we explore what happens when ice overtakes our planet and how we investigate icy conditions of the distant past, and we’ll take a close look at the most recent (and ongoing) global climate event that we commonly call the Ice Age.

In the news: distant space objects, snake embryos, Jurassic chirps, and polar dinosaur nests.
