How do very complex systems—natural, human, built, technological—interact under rapidly changing conditions? Join us for a free-wheeling conversation between author Andy Revkin and ASU Sustainability Scientist Brad Allenby, as they discuss how we can build social, economic, and environmental sustainability in a highly unpredictable, contingent world.

One of America’s most honored science writers, Revkin has been reporting in print and on Dot Earth for The New York Times since 1995. He has spent a quarter century writing on the environment, covering subjects ranging from Hurricane Katrina and the Asian tsunami to the assault on the Amazon and the troubled relationship of climate science and politics. In his blog, Dot Earth, Revkin examines efforts to balance human affairs with the planet’s limits.
