In 250 million years, the map of the world will be unrecognizable. But as the continents merge into a new supercontinent like Pangea Ultima, they may also be building a planetary furnace. In this episode, Albany Adams and Grace Shelly decode the "Triple Whammy" that could end the era of mammals.

We investigate the four competing models for Earth’s final landmass—from the polar huddle of Amasia to the equatorial heat of Aurica. We break down the terrifying climate simulations that predict 150°F summers, the "super-tidal" cycles that could starve the oceans of oxygen, and how NASA is using these future Earths to find life on distant exoplanets. It’s a journey into deep time, where the very ground beneath us is moving toward a tipping point.
