Over the last 11,700 years, during which human civilization developed, the earth has existed within what geologists refer to as the Holocene Epoch. Now science is telling us that the Holocene Epoch in the geological time scale ended, replaced by the onset of a new, more dangerous Anthropocene Epoch, which began around 1950. The Anthropocene Epoch is characterized by an “anthropogenic rift” in the biological cycles of the Earth System, marking a changed reality in which human activities are now the main geological force impacting the earth as a whole, generating at the same time an existential crisis for the world’s population. What caused this massive shift in the history of the earth?...
This book outlines the development and perspectives of the Anthropocene concept by Paul J. Crutzen and his colleagues from its inception to its implications for the sciences, humanities, society and politics. The main text consists primarily of articles from peer-reviewed scientific journals and other scholarly sources. It comprises selected articles on the Anthropocene published by Paul J. Crutzen and a selection of related articles, mostly but not exclusively by colleagues with whom he collaborated closely. • In the year 2000 Nobel Laureate Paul J. Crutzen proposed the Anthropocene concept as a new epoch in Earth’s history • Comprehensive collection of articles on the Anthropocene by Paul J. Crutzen and his colleagues• Unique primary research literature and Crutzen’s comprehensive bibliography• Paul Crutzen’s scientific investigations into human influences on atmospheric chemistry and physics, the climate and the Earth system, leading to the conception of the Anthropocene• Reflections on the Anthropocene and its implications• Bibliometric review of the spread of the use of the Anthropocene concept in the Natural and Social Sciences, Humanities and Law
Als der Atmosphärenchemiker Paul Crutzen und der Limnologe Eugene F. Stoermer im Jahr 2000 den Begriff des Anthropozäns einführten, traten sie eine wissenschaftliche Debatte los, die rasch an Dynamik gewann und mittlerweile in großer disziplinärer Breite verhandelt wird. Dabei verwischen etablierte Grenzziehungen zwischen tradierten disziplinären Kulturen der Wissensproduktion, was die beteiligten AkteurInnen dazu zwingt, aus ihren Arenen herauszutreten und mit den jeweils anderen Akteursgruppen einen Aushandlungsprozess über die Evidenzsicherung zu führen. Die jeweiligen Evidenzpraktiken geraten unter Legitimierungsdruck und werden im inter- und transdisziplinären Raum neu verhandelt. Fabienne Will beleuchtet die Anthropozändebatte als trading zone, in der nicht nur zentrale Fragen zur Gegenwart und Zukunft der Menschheit auf der Erde, sondern darauf bezogen auch grundlegende Verständnisse von Evidenzproduktion und -sicherung verhandelt werden.
Reviews the evidence underpinning the Anthropocene as a geological epoch written by the Anthropocene Working Group investigating it. The book discusses ongoing changes to the Earth system within the context of deep geological time, allowing a comparison between the global transition taking place today with major transitions in Earth history.
Poluição Marinha: Principais Aspectos é uma síntese de 15 anos de trabalhos e publicações voltados à poluição do ambiente marinho, em especial no Nordeste do Brasil. A contaminação da zona costeira e oceanos é discutida a partir de dados quantitativos e qualitativos. Ao longo do livro são apresentados os principais conceitos, fontes e tipos de poluição nos ambientes costeiros e marinhos. A interação do homem com o mar, representada pelo desenvolvimento acelerado dos núcleos urbanos em áreas costeiras, traz como consequência todo tipo de contaminação. Desta maneira,os capítulos ressaltam esta interação através da apresentação do Turismo como fonte de poluição marinha, os Esgotos Domésticos, Efluentes Industriais e o Lixo marinho.
Addressing one of the most pressing environmental issues, this topical book carefully inspects the current extent of the plastic pollution crisis and observes contemporary approaches to its regulation. By adopting a strong interdisciplinary approach, this book fully encapsulates the key challenges and solutions surrounding this globally applicable problem.
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.
The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and the...
Marine debris is a global pollution problem affecting marine life, maritime commerce and environmental quality. Scientists, policymakers and the public must be knowledgeable about the source, impact and control efforts if effective solutions are to be developed. Marine Debris addresses the origin of persistent solid waste in the ocean, from urban and rural discharges to waste from ships and the recreational use of oceans. The book identifies key issues from biological, technological, economic and legal perspectives, and gives a framework for controlling each of the main sources of marine debris.
