The Anthropocene: a new epoch of geological time?
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...
متن کاملAnthropocene Security
Earth system science now suggests that because of the huge transformations caused by human activity we now effectively live in a new geological era called the Anthropocene. The innovations in understanding the earth system make it clear that humanity is a key part of the changing biosphere and this new contextual understanding renders traditional ideas of environment inadequate in dealing with ...

The International Geosphere Biosphere Program has recently suggested that we now live in a new era of natural history, the Anthropocene, one marked by the emergence of a new series of geological, biological and climatological forcing mechanisms in the biosphere. These new forcing agents are changing the composition of trace gases in the atmosphere, moving large amounts of material all over the ...
متن کاملGeobiology of the Anthropocene
Homo sapiens first appeared on the Earth somewhere in Africa roughly 200 000 years ago. It happened with little fanfare; few could have imagined that this new species of primate would someday disrupt the Earth system to the point of defining a new geologic epoch around its legacy. Indeed, the first 150 000 years of the natural history of our species, mostly in Africa, were fairly uneventful for...
متن کاملStratigraphy of the Anthropocene.
The Anthropocene, an informal term used to signal the impact of collective human activity on biological, physical and chemical processes on the Earth system, is assessed using stratigraphic criteria. It is complex in time, space and process, and may be considered in terms of the scale, relative timing, duration and novelty of its various phenomena. The lithostratigraphic signal includes both di...
