Professors Anthony D. Barnosky and Elizabeth A. Hadly have been married and working together for nearly 25 years to uncover the scientific underpinnings that will help ensure a viable future for humanity.Anthony Barnosky is the Professor of Integrative Biology, University of California. A renowned paleobiologist, he has spent 30 years conducting research related to past planetary changes, and what they mean for forecasting the changes to come on Planet Earth in the next few decades.Elizabeth Hadly is the Chair of Environmental Biology at Stanford University. She has spent more than 25 years studying environmental change in landscapes all over the world, conducting primary research on how living and fossil species can reveal the ways in which current human impacts are influencing ecological systems.

‘Just because we have collectively lost interest in the doom clock doesn't mean it has stopped ticking … Barnosky and Hadly are serious players … When tipping points are reached, the change can be violent as well as sudden … you cannot fault the authors' determination to try to warn us’ Newsweek‘In ‘End Game’, academics Anthony Barnosky and Elizabeth Hadly eloquently lay out the ecological perils we face, deftly showing how they might segue into food and water shortages, disease, resource wars and mass migrations … Now we know the challenges for the 21st century; we just need to act’ Fred Pearce, New Scientist
