If you take a look at global temperature graphs that span millions or billions of years, you can see that our planet’s temperature has made wild swings. In fact, the Earth used to be completely covered in snow and ice! So, what’s the big deal about a few degrees of warming today? In this episode of Weathered, we take a deep dive into Earth’s climate history in order to better understand our current moment.

Weathered is a show hosted by weather expert Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.
