Petrifying Earth Process: The Stratigraphic Imprint of Key Earth System Parameters in the Anthropocene

By Jan Zalasiewicz, Will Steffen, Reinhold Leinfelder, Mark Williams, Colin Waters | Theory, Culture & Society Abstract 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…

The Anthropocene: Scientists respond to criticisms of a new geological epoch

Press Release A team of academics led by the University of Leicester has responded to criticisms of the proposal to formalise a new geological epoch – the Anthropocene. Geological critics of a formalised Anthropocene have alleged that the idea did not arise from geology; that there is simply not enough physical evidence for it as…

Anthropocene: its stratigraphic basis

By Jan Zalasiewicz, Colin Waters & Martin J. Head | Nature, Correspondence  As officers of the Anthropocene Working Group (AWG; J.Z. and C.W.) and chair of the Subcommission on Quaternary Stratigraphy (SQS; M.J.H.) of the International Commission on Stratigraphy (ICS), we note that the AWG has less power than Erle Ellis and colleagues imply (Nature 540, 192–193; 2016). Its role…

Can Humans Go From Unintended Global Warming to Climate By Design?

  By Andrew C. Revkin | Dot Earth, The New York Times Geoengineering is in the wind more and more these days, particularly the use of sun-blocking aerosols as a cheap, temporary counterweight to greenhouse-gas-driven global warming. In pondering the plausibility or desirability of such a tool, it might be useful to start with a thought experiment: 1) Suppose…

Atomic bombs and oil addiction herald Earth’s new epoch: The Anthropocene

By Paul Voosen | Science Magazine | August 24, 2016 Just after World War II, when the atomic bombs fell and our thirst for coal and oil became a full-blown addiction, Earth entered the Anthropocene, a new geologic time when humanity’s environmental reach left a mark in sediments worldwide. That’s the majority conclusion of the Anthropocene Working Group, a…

Define the Anthropocene in terms of the whole Earth

By Clive Hamilton | Nature | August 17, 2016 Do we live in the Anthropocene? Officially, not yet — although the debate about whether to declare a new geological epoch will resurface later this month at the International Geological Congress in Cape Town, South Africa. The concept of the Anthropocene has become well known and is much…

Changing the Face of the Earth

By Dr. Colin Waters | LaboratoryNews | April 12, 2016 We have geo-engineered the Earth expertly for our own ends, but will humanity’s indelible stamp on the planet define an entire geological epoch? The term “Anthropocene” was coined by Paul Crutzen 16 years ago to mark the present as distinct from previous geological time. The term has…
