A great deal of literature has already anointed the hero in the fight against climate change: the city. Beginning with David Owens' Green Metropolis and including the work of Paul Hawken, Ed Glaeser, and countless others, the city has come to symbolize all the ways that humans can live densely and tread lightly on the Earth.
These accolades might be premature. In his brief but wide-ranging book Climatopolis: How Our Cities Will Thrive in a Hotter Future, Matthew Kahn renders no such heroes.
