FROM AN AWARD-WINNING SCIENCE JOURNALIST comes an urgent investigation of environmental migration--the most underreported, seismic consequence of our climate crisis that will force us to change where--and how--we live.

"An IMPORTANT and PROVOCATIVE start to a crucial conversation." --Bill McKibben

"We are facing a species emergency. We can survive, but to do so will require a planned and deliberate migration of a kind humanity has never before undertaken. This is the biggest human crisis you've never heard of."

Drought-hit regions bleeding those for whom a rural life has become untenable. Coastlines diminishing year on year. Wildfires and hurricanes leaving widening swaths of destruction. The culprit, most of us accept, is climate change, but not enough of us are confronting one of its biggest, and most present, consequences: a total reshaping of the earth's human geography. As Gaia Vince points out early in Nomad Century, global migration has doubled in the past decade, on track to see literal billions displaced in the coming decades. What exactly is happening, Vince asks? And how will this new great migration reshape us all?

In this deeply-reported clarion call, Vince draws on a career of environmental reporting and over two years of travel to the front lines of climate migration across the globe, to tell us how the changes already in play will transform our food, our cities, our politics, and much more. Her findings are answers we all need, now more than ever.
