Spheroidal carbonaceous fly ash particles provide a globally synchronous stratigraphic marker for the Anthropocene.
Human impacts on Earth are now so great that they have led to the concept of a new geological epoch defined by this global human influence: the Anthropocene. While not universally accepted, the term is increasingly popular and widely used. However, even among proponents, there is considerable debate regarding when the epoch may have started, from coeval with the Holocene, through the Industrial...
متن کاملPetrifying Earth Process : the stratigraphic imprint of key Earth System parameters in the Anthropocene
The Anthropocene concept arose within the Earth System science (ESS) community, albeit explicitly as a geological (stratigraphical) time term. Its current analysis by the stratigraphical community, as a potential formal addition to the Geological Time Scale, necessitates comparison of the methodologies and patterns of enquiry of these two communities. One means of comparison is to consider some...
متن کاملSpheroidal carbonaceous particles are a defining stratigraphic marker for the Anthropocene
There has been recent debate over stratigraphic markers used to demarcate the Anthropocene from the Holocene Epoch. However, many of the proposed markers are found only in limited areas of the world or do not reflect human impacts on the environment. Here we show that spheroidal carbonaceous particles (SCPs), a distinct form of black carbon produced from burning fossil fuels in energy productio...

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 ...
