The Long Emergency: Surviving the Converging Catastrophes of the Twenty-first Century is a book by James Howard Kunstler (Grove/Atlantic, 2005) exploring the consequences of a world oil production peak, coinciding with the forces of climate change, resurgent diseases, water scarcity, global economic instability and warfare to cause major trouble for future generations.

The book's principal theme explores the effects of a peak in oil extraction on American society as well as the rest of the world.

In both this book and in his other writings, Kunstler argues that the economic upheavals caused by peak oil will force Americans to live in more localized, self-sufficient communities.

Kunstler's premise is that "cheap, plentiful" and easy-to-find oil is the foundation of industrial society and the pervasiveness of its effects is not widely appreciated.

In his review for the Daily Camera, Jim Charlier praised the book as a powerful and urgent contribution to doomsday literature, challenging conventional thinking with its proposition of temporary human ascendancy and recommending it as essential reading.
