Résumé

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, including anthropogenic climate change. This book, written by the high-profile international team analysing the Anthropocene's potential addition to the Geological Time Scale, presents evidence for defining the Anthropocene as a geological epoch. It discusses Anthropocene stratigraphy and ongoing changes to the Earth system, including the climate, oceans and biosphere. The evidence for the Anthropocene is examined in detail, ranging from chemical signals arising from pollution, to physical changes to the landscape associated with urbanisation and biological changes associated with species invasion and extinctions. The scale, manner and rate of 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 to the Earth system, and compare the global transition taking place today with major transitions in Earth history. Key aspects of the geological background are explained, providing an authoritative review of the Anthropocene for graduate students and academic researchers across a broad range of scientific, social science and humanities disciplines.
