Gaia Vince, author of Nomad Century: How Climate Migration Will Reshape Our World, presents a stark look at the inevitable mass migration caused by a changing climate, which she argues will force billions to move from the tropics to the habitable north this century. She identifies the "four horsemen of the Anthropocene"—fire, heat, flood, and drought—as the primary drivers of this upheaval. Using the example of a Peruvian farmer forced into a Lima slum, Vince illustrates how climate migration is already underway and often results in precarious existences due to a lack of legal pathways. The book advocates for a radical rethinking of borders and global citizenship, suggesting that the global north needs millions of workers to avoid a demographic crisis and support aging populations. Vince proposes a new UN body to manage migration, using quota systems to match migrants with labor needs in expanded northern cities. She envisions a future where biotechnology, vertical farming, and lab-grown meat provide sustainable nutrition for a global population of ten billion. Vince also explores technological solutions for planetary restoration, including geoengineering methods like ocean fertilization with iron and enhanced weathering of rocks to sequester carbon. While acknowledging the controversy of such projects, she argues that decoupling economic growth from environmental destruction is essential for survival. Ultimately, the book is a call for global inclusivity and a planned strategy to make the unavoidable flux of people work to the advantage of all. (3)
