Climate change is coming. With the majority of the world's population living in cities, how they will fare in a hotter world is a fundamental question. Matthew Kahn, professor at UCLA's Institute of the Environment, Department of Economics, and Department of Public Policy, feels optimistic about the quality of our lives in the city of the future, despite very different climate conditions than we face today. He bases this optimism on our ability to pursue our own narrow self interest in a capitalist economy. (#19386)
