Gaia Vince (@wanderinggaia) is an award-winning science writer and author. She is particularly interested in the interaction between human systems and Earth’s planetary systems. Her research has taken her around the world. Gaia’s latest book is Nomad Century: How Climate Migration Will Reshape Our World. We are already at 1.6 degrees Celsius above pre-industrial temperatures, with significantly more to come. The four horsemen of the anthropocene - fire, heat, drought, and flood - will lead human migration on an unprecedented scale. Gaia describes what we must do, individually and collectively, to prepare.
