The Anthropocene, a term launched into public debate by Nobel Prize winner Paul Crutzen, has been used informally to describe the time period during which human actions have had a drastic effect on the Earth and its ecosystems. This book presents evidence for defining the Anthropocene as a geological epoch, written by the high-profile international team analysing its potential addition to the geological time scale. The evidence ranges from chemical signals arising from pollution, to landscape changes associated with urbanisation, and biological changes associated with species invasion and extinctions. Global environmental change is placed within the context of planetary processes and deep geological time, allowing the reader to appreciate the scale of human-driven change and compare the global transition taking place today with major transitions in Earth history. This is an authoritative review of the Anthropocene for graduate students and academic researchers across scientific, social science and humanities disciplines.
