Al Gore shaped national debate with “An Inconvenient Truth” in 2006, and framed discourse with “The Assault on Reason” the following year. Random House has landed him for a new book for 2012, a yet-to-be-titled work that will focus on the “political, social and economic forces that are shaping what America and the world will become in ensuing decades.”

The book is the first acquisition of Jon Meacham, the former editor of Newsweek who recently joined Random House as executive VP and executive editor.

In an interview, Meacham called Gore “a philosophical pragmatist or pragmatic philosopher, depending on how you choose to look at him,” whose “combination of intellectual energy and practical experiences make him worth listening to.”

“He’s found a way to shape the country and the world in a way not many people have done,” he said.

While the concept for the book has a broad scope, so did “Truth” and “Reason,”  both of which became bestsellers. The books also were connected in the nature of how public awareness can ebb and flow: “Truth” explained the climate crisis, while “Reason” explained why facts get lost in today’s media din. Given that polls show belief in man made global warming has actually lost ground in recent years, and legislation has stalled in Congress, it’s been a disconcerting time for those inspired by Gore’s call to action.

Gore again will address the climate crisis in this book, but as part of an effort to “help start a conversation about the large-scale drivers of change that are defining and shaping our future,” he said in a statement. He also cited the development of “radically new technologies” and poverty, globalization, and “the democratization of knowledge accompanying the emergence of a ubiquitous Internet linking ever more intelligent devices.”
