Pangea Proxima: When the Continents Return

By John S. Pritchett

The continents feel permanent because we live too briefly to see them move.

But Earth is not finished changing.

Pangea Proxima explores one of the most fascinating possibilities in planetary science: the future return of a supercontinent. Hundreds of millions of years from now, the continents may once again gather into a vast landmass, reshaping oceans, climates, coastlines, mountain ranges, and the conditions for life.

Written for general readers, this book follows the long pattern of continental assembly and breakup, from ancient supercontinents such as Columbia, Rodinia, and Pangea to possible future worlds including Pangea Proxima, Amasia, Aurica, and Novopangaea. Along the way, it explains how plate tectonics opens and closes oceans, how continental collisions build mountains, how supercontinents affect climate and habitability, and why Earth's surface is never truly still.

Pangea Proxima is not a prediction of an exact future map. It is a journey into deep time, showing how the forces that shaped Earth's past are still preparing the planet for worlds that do not yet exist.

The world beneath our feet is not finished.

It is moving.
