The Working Group on the Anthropocene
Scale and diversity of the physical technosphere
We assess the scale and extent of the physical technosphere, defined here as the summed material output of the contemporary human enterprise. It includes active urban, agricultural and marine components, used to sustain energy and material flow for current human life, and a growing residue layer, currently only in small part recycled back into the active component. Preliminary estimates suggest a technosphere mass of approximately 30 trillion ton…
Being human in the Anthropocene
This essay aims to show how what is most intimately and essentially human – our ideas, personal purposes, feelings, and dreams – finds space for expression within the autonomous, unfeeling, physical dynamics of the technosphere – the defining system of the Anthropocene. The approach adopted is based on systems science and aims to avoid metaphysical assumptions about the nature and importance of human values. A non-humanistic analysis of human pot…
Purpose in the Anthropocene
The Anthropocene biosphere
The geological record preserves evidence for two fundamental stages in the evolution of Earth's biosphere, a microbial stage from ~3.5 to 0.65 Ga, and a metazoan stage evident by c. 650 Ma. We suggest that the modern biosphere differs significantly from these previous stages and shows early signs of a new, third stage of biosphere evolution characterised by: (1) global homogenisation of flora and fauna; (2) a single species ( Homo sapiens) comman…
Diachronous beginnings of the Anthropocene
Across a large proportion of Earth's ice-free land surfaces, a solid-phase stratigraphic boundary marks the division between humanly modified ground and natural geological deposits. At its clearest, the division takes the form of an abrupt surface at the base of deposits variously called 'artificial ground', 'anthropogenic ground' or 'archaeological stratigraphy' - which together comprise a distinctive part of the geosphere called the 'archaeosph…
Humans and technology in the Anthropocene
Humans play an essential role in creating the technological systems of the Anthropocene, but, nonetheless, large-scale technology - the 'technosphere' - operates according to a quasi-autonomous dynamics, summarized by six rules: (1) the rule of inaccessibility, that large components of the technosphere cannot directly influence the behavior of their human parts; (2) the rule of impotence, that most humans cannot significantly influence the behavi…
The technofossil record of humans
As humans have colonised and modified the Earth's surface, they have developed progressively more sophisticated tools and technologies. These underpin a new kind of stratigraphy, that we term technostratigraphy, marked by the geologically accelerated evolution and diversification of technofossils - the preservable material remains of the technosphere (Haff, 2013), driven by human purpose and transmitted cultural memory, and with the dynamics of a…
