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 ...
human-induced climate change, with such rapid and continuing global-scale warming, is historically unprecedented and signifies that human pressures on earth’s life-supporting natural systems now exceed the planet’s bio-geo-capacity. the risks from climate change to health and survival in populations are diverse, as are the social and political ramifications. although attributing observed health...
The current law of the sea provides a framework for various specific issues, but is incapable of responding adequately to the overall challenges facing humankind, now conceivably already living in the Anthropocene. The linkages between the development of the law of the sea and the current process towards formal recognition of an Anthropocene epoch are twofold. First, there is a linkage of origi...
Though many scientists and scholars of the environmental humanities are referring to the current geological era as the anthropocene, this article argues that there are some problems with this trope and the narrative that emerges from it. First, responsibility for the current era of climate weirding is not shared equally, some humans are way more responsible than others. Second, the claim of the...
It has been proposed that we are now living in a new geological epoch known as the Anthropocene, which is specifically defined by the impacts that humans are having on the Earth's biological diversity and geology. Although the proposal of this term was borne out of an acknowledgement of the negative changes we are imparting on the globe (e.g. climate change, pollution, coastal erosion, species ...
The human imprint on the global environment has now become so large and active that it rivals some of the great forces of Nature in its impact on the functioning of the Earth system. Although global-scale human influence on the environment has been recognized since the 1800s, the term Anthropocene, introduced about a decade ago, has only recently become widely, but informally, used in the globa...
Advances in science have illuminated the role of the “ecological theatre”—the total living environment—in human health. In a rapidly changing epoch known as the anthropocene, microbiome science is identifying functional connections between all life, both seen and unseen. Rather than an easily identifiable era appearing in rock strata, the anthropocene is more of a diagnostic syndrome, a set of ...
Data and computer simulations are reviewed to help better define the timing and magnitude of human influence on sediment flux--the Anthropocene epoch. Impacts on the Earth surface processes are not spatially or temporally homogeneous. Human influences on this sediment flux have a secondary effect on floodplain and delta-plain functions and sediment dispersal into the coastal ocean. Human impact...
When did the Anthropocene begin? A mid-twentieth century boundary level is stratigraphically optimal
We evaluate the boundary of the Anthropocene geological time interval as an epoch, since it is useful to have a consistent temporal definition for this increasingly used unit, whether the presently informal term is eventually formalized or not. Of the three main levels suggested e an ‘early Anthropocene’ level some thousands of years ago; the beginning of the Industrial Revolution at ~1800 CE (...
