You wait ages for the bus, and then three come along at once. Books are a bit like that, too, although in this case it's only a pair of them, both tackling the question of what to do about all the "climate refugees". (The United Nations' International Organization for Migration estimates that 1.5 billion people may be forced to move in the next thirty years alone.)
First up is Gaia Vince, a British environmental journalist who has interviewed a great many climate scientists. Her book is Nomad Century: How Climate Migration Will Reshape Our World, and she has certainly grasped the key political problem in a rapidly heating world: some people will be hurt a great deal more than others.
It's mainly a question of distance from the equator. Countries in the tropics and the sub-tropics will be experiencing intolerable temperatures, accompanied by monster storms, droughts and floods, well before mid-century, while those in the temperate latitudes will suffer inconvenience and discomfort but far less actual damage.
