"A relentless reckoning of how we, as a species, got ourselves into the mess we're in today, . . . told with determination and in chiseled, almost literary prose."--Christoph Irmscher, Wall Street Journal

Meteorites, mega-volcanoes, and plate tectonics--the old forces of nature--have transformed Earth for millions of years. They are now joined by a new geological force--humans. Our actions have driven Earth into a new geological epoch, the Anthropocene. For the first time in our home planet's 4.5-billion-year history a single species is increasingly dictating Earth's future.

To some the Anthropocene symbolizes a future of superlative control of our environment. To others it is the height of hubris, the illusion of our mastery over nature. Whatever your view, just below the surface of this odd-sounding scientific word, the Anthropocene, is a heady mix of science, philosophy, and politics linked to our deepest fears and utopian visions.

Tracing our environmental impacts through time, scientists Simon Lewis and Mark Maslin reveal a new view of human history and a new outlook for the future of humanity in the unstable world we have created. A Preface written exclusively for this edition reviews recent scientific updates on the escalating climate crisis and new ideas about how to define the geological time period in which we live.
