Eight thousand years ago, human beings invented skiing. Since then, it’s evolved into a $12-billion global industry. But as the journalist Porter Fox notes in a new book, with global warming accelerating, there’s a very real chance that skiing won’t even exist by the end of the century. Fox says that while skiers may be bummed by the possibility of a world with less snow, the impacts for the rest of the world will likely be far worse. Fox joins us Thursday to explore the history of skiing and the future of snow on a warming planet.

Porter Fox has been an editor for Power magazine since 1999. His writing has appeared in Power, the New York Times and Outside. His first book is called Deep: The Story of Skiing and the Future of Snow [Amazon].
