Mankind’s impact on Earth extends well beyond climate change to the broader biosphere, where the conditions that nurtured the development of modern humans are at risk of being lost in a new epoch known as the Anthropocene.---Climate change makes headline news, but mankind's changes to planet Earth go well beyond rising temperatures. In this episode of Energy Policy Now prominent earth system scientist Will Steffen explores the dawn of a new geologic epoch, the Anthropocene, where the systems of sea, land, and air will be unlike those experienced in human history.The term Anthropocene, coined less than two decades ago, emphasizes the rising influence of humans on earth system processes, and our emerging role as the dominant force shaping Earth’s biologic and geologic systems. Steffen looks at the political and economic systems that have accelerated man’s impact on Earth since the middle of the 20th century, and at the role of technology and policy in slowing global change.Will Steffen is emeritus professor at the Australian National University, former executive director of the International Geosphere-Biosphere Programme, and a former member of the Australian government’s Climate Commission.
