This review article summarizes the main tenets of institutional theory as they apply to the topic of the Anthropocene in the domain of organization and the natural environment. But our review is distinctive for two reasons: First, it is focused on providing avenues researching the Anthropocene Era. Second, while based on the trajectory of current, accumulated theory and research, our review is ...

This and two companion papers (The Anthropocene and Geography I: The back story and The Anthropocene and Geography III: Future Directions) consider the relevance of 'the Anthropocene' to present and future research in Geography. Along with the concept of 'planetary boundaries', the idea that humanity has entered a new geological epoch of its own making is currently attracting considerable atten...

Palaeontology formed the basis for defining most of the geological eras, periods, epochs and ages that are commonly recognized. By the same token, the Anthropocene can be defined by diverse palaeontological criteria, in accordance with commonly accepted biostratigraphic practice. The most useful Anthropocene biostratigraphic zones will be assemblage and abundance zones based on mixes of native ...

We explore the development of the Anthropocene, the current epoch in which humans and our societies have become a global geophysical force. The Anthropocene began around 1800 with the onset of industrialization, the central feature of which was the enormous expansion in the use of fossil fuels. We use atmospheric carbon dioxide concentration as a single, simple indicator to track the progressio...

This essay addresses the conservation issues facing mangroves in the Anthropocene, defined as the era of human domination over the world. We review the laws, policies, international agreements, and local actions that address the conservation of mangrove forests in the Neotropics and relate them to the Anthropocene. Collaboration between governments, non-governmental organizations, and communiti...

The term 'Anthropocene' was first used in the year 2000 to refer to the current time period in which human impacts are at least as important as natural processes. It is currently being considered as a potential geological epoch, following on from the Holocene. While most environmental scientists accept that many key environmental parameters are now outside their Holocene ranges, there is no agr...

The term "Anthropocene" was coined by Professor Paul Crutzen in 2000 to describe an unprecedented era in which anthropogenic activities are impacting planet Earth on a global scale. Greatly increased emissions into the atmosphere, reflecting the advent of the Industrial Revolution, have caused significant changes in both the lower and upper atmosphere. Atmospheric reactions of the anthropogenic...

Distributions of anthropogenic signatures (impacts and activities) are mathematically analysed. The aim is to understand the Anthropocene and to see whether anthropogenic signatures could be used to determine its beginning. A total of 23 signatures were analysed and results are presented in 31 diagrams. Some of these signatures contain undistinguishable natural components but most of them are o...

Anthropogenic changes to the Earth's climate, land, oceans and biosphere are now so great and so rapid that the concept of a new geological epoch defined by the action of humans, the Anthropocene, is widely and seriously debated. Questions of the scale, magnitude and significance of this environmental change, particularly in the context of the Earth's geological history, provide the basis for t...

In 2000, some two dozen top scientists gathered south of Mexico City to discuss the implications of their multidisciplinary Earth sciences research, and Paul Crutzen was getting frustrated. The work, part of the International Geosphere-Biosphere Program (IGBP) (www.igbp.net), had documented vast planetary changes caused by humans, such as soaring levels of carbon dioxide in the atmosphere. Howe...
