Climate Migration Is Inevitable: The Global South, the Four Horsemen, and the Necessity of Movement. Gaia Vince's book, Nomad Century: How Climate Migration Will Reshape Our World, examines the statistics warning that the climate of the near future will be dramatically different. Vince emphasizes that climate migration is "very much underway" and inevitable, highlighting the plight of Abel Cruz, a farmer in rural Peru who moved to Lima due to drought but became part of the growing global south slums. The phenomenon of the global south moving north is overwhelming, as the tropics are becoming dangerous and unlivable, compelling people to move to higher latitudes in the northern temperate zone, which are generally wealthier and better equipped to adapt. Vince refers to the primary threats that force movement as the "four horsemen of the Anthropocene": fire, heat, flood, and drought, which destroy livelihoods and property.
