Book excerpt: Humankind has pervasively influenced the Earth’s atmosphere, biosphere, geosphere, hydrosphere and cryosphere, arguably to the point of fashioning a new geological epoch, the Anthropocene. To constrain the Anthropocene as a potential formal unit within the Geological Time Scale, a spectrum of indicators of anthropogenically-induced environmental change is considered, and shown as stratigraphical signals that may be used to characterize an Anthropocene unit, and to recognize its base. This volume describes a range of evidence that may help to define this potential new time unit and details key signatures that could be used in its definition. These signatures include lithostratigraphical (novel deposits, minerals and mineral magnetism), biostratigraphical (macro- and micro-palaeontological successions and human-induced trace fossils) and chemostratigraphical (organic, inorganic and radiogenic signatures in deposits, speleothems and ice and volcanic eruptions). We include, finally, the suggestion that humans have created a further sphere, the technosphere, that drives global change.

Book Synopsis The Birth of the Anthropocene by : Jeremy Davies

Download or read book The Birth of the Anthropocene written by Jeremy Davies. This book was released on 2016-05-24. Available in PDF, EPUB and Kindle. Book excerpt: The world faces an environmental crisis unprecedented in human history. Carbon dioxide levels have reached heights not seen for three million years, and the greatest mass extinction since the time of the dinosaurs appears to be underway. Such far-reaching changes suggest something remarkable: the beginning of a new geological epoch. It has been called the Anthropocene. The Birth of the Anthropocene shows how this epochal transformation puts the deep history of the planet at the heart of contemporary environmental politics. By opening a window onto geological time, the idea of the Anthropocene changes our understanding of present-day environmental destruction and injustice. Linking new developments in earth science to the insights of world historians, Jeremy Davies shows that as the Anthropocene epoch begins, politics and geology have become inextricably entwined.

Book Synopsis Anthropocene: A Very Short Introduction by : Erle C. Ellis

Download or read book Anthropocene: A Very Short Introduction written by Erle C. Ellis. This book was released on 2018-02-22. Available in PDF, EPUB and Kindle. Book excerpt: The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species - these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news. Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world, kindling intense debates. The reason is clear. The Anthropocene represents far more than just another interval of geologic time. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised. This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: the nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? Erle Ellis considers the many ways that the Anthropocene's "evolving paradigm" is reshaping the sciences, stimulating the humanities, and foregrounding the politics of life on a planet transformed by humans. The Anthropocene remains a work in progress. Is this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption? Ellis offers an insightful discussion of our role in shaping the planet, and how this will influence our future on many fronts.
