We know what we want the world to be like in forty years. We know what the world could be like in forty years if we all did what needs to be done to create a more sustainable future. But what do we know about what the world will actually be like in forty years? That is the question Jorgen Randers tries to answer in 2052. Drawing on global forecasting tools, his own experience in the sustainability arena, and the predictionsincluded in the bookof more than thirty leading scientists, economists, futurists, and other thinkers, Randers guides us through the future he feels is most likely to emerge. Not to scare us. But to prepare us, and, where necessary, sound a call for changing course.
