With help from Rodale, Melcher Media and Push Pop Press, Apple board member Al Gore has released a new e-book on the App Store, Our Choice. The title is described as a followup to An Inconvenient Truth, and once again tries to explain the causes of global warming as well as current and potential solutions. All of Gore's earnings from the app are being funneled back into the Alliance for Climate Protection, his non-profit educational organization.
