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.

Encyclopedia of the Anthropocene presents a currency-based, global synthesis cataloguing the impact of humanity’s global ecological footprint. Covering a multitude of aspects related to Climate Change, Biodiversity, Contaminants, Geological, Energy and Ethics, leading scientists provide foundational essays that enable researchers to define and scrutinize information, ideas, relationships, meanings and ideas within the Anthropocene concept. Questions widely debated among scientists, humanists, conservationists, politicians and others are included, providing discussion on when the Anthropocene began, what to call it, whether it should be considered an official geological epoch, whether it can be contained in time, and how it will affect future generations. Although the idea that humanity has driven the planet into a new geological epoch has been around since the dawn of the 20th century, the term ‘Anthropocene’ was only first used by ecologist Eugene Stoermer in the 1980s, and hence popularized in its current meaning by atmospheric chemist Paul Crutzen in 2000. Presents comprehensive and systematic coverage of topics related to the Anthropocene, with a focus on the Geosciences and Environmental science Includes point-counterpoint articles debating key aspects of the Anthropocene, giving users an even-handed navigation of this complex area Provides historic, seminal papers and essays from leading scientists and philosophers who demonstrate changes in the Anthropocene concept over time

Provisional Cities

Cautionary Tales for the Anthropocene

This book considers the provisional nature of cities in relation to the Anthropocene – the proposed geological epoch of human-induced changes to the Earth system. It charts an environmental history of curfews, admonitions and alarms about dwelling on Earth. ‘Provisional cities’ are explored as exemplary sites for thinking about living in this unsettled time. Each chapter focuses on cities, settlements or proxy urbanisations, including past disaster zones, remote outposts in the present and future urban fossils. The book explores the dynamic, changing and contradictory relationship between architecture and the global environmental crisis and looks at how to re-position architectural and urban practice in relation to wider intellectual, environmental, political and cultural shifts. The book argues that these rounder and richer accounts can better equip humanity to think through questions of vulnerability, responsibility and opportunity that are presented by immense processes of planetary change. These are cautionary tales for the Anthropocene. Central to this project is the proposition that living with uncertainty requires that architecture is reframed as a provisional practice. This book would be beneficial to students and academics working in architecture, geography, planning and environmental humanities as well as professionals working to shape the future of cities.

Marine Tephrochronology

This Special Publication includes articles presenting recent advances in marine tephrochronological studies and outlines innovative techniques in geochemical fingerprinting, stratigraphy and the understanding of depositional processes. It represents a significant resource for the palaeoceanographic community at a time when marine tephrochronology is being more widely recognized. It will also serve as a valuable reference to a much wider community of Earth scientists, climate scientists and archaeologists, particularly in highlighting the role of tephra studies in stratigraphy and regional/extra-regional correlations, as well as in tracing the long-term history of regional and global volcanism in the deep-sea archive.
