The Anthropocene concept arose within the Earth System science community, albeit explicitly as a geological 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 of the most widely used results of the ESS, the ‘planetary boundaries’ concept of Rockström and colleagues, and the ‘Great Acceleration’ graphs of Steffen and colleagues, (...) in terms of their stratigraphical expression. This expression varies from virtually non-existent to pronounced and many-faceted, while in some cases stratigraphical proxies may help constrain anthropogenic process. The Anthropocene concepts of the ESS and stratigraphy emerge as complementary, and effective stratigraphic definition should facilitate wider transdisciplinary communication. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Far-Future Paleontology: The Baffling Case of Brunaspis enigmaticaAnne-Sophie Milon (bio) and Jan Zalasiewicz (bio)Paleontologists, for more than two centuries, have studied and debated the petrified remains of plants and animals that have evolved over the past three billion years on Earth. They have argued over the grand concepts that they reveal, such as biological evolution and climate change, and also the many specific questions thrown up by these (...) relics: was such-and-such a shell, a mollusk, or an arthropod? Did this fossil fish live high up in the water, among the plankton, or grub in the mud on the sea floor?These studies have for many paleontologists been a blessedly human-free zone, detached from the busy realities of our everyday lives. The science of paleontology, though, is simply one obscure part of a burgeoning and rapidly evolving technosphere that underpins our lives, and that is now evolving millions of new kinds of fossils—technofossils—far more rapidly than ever happened in biological evolution. Many of these objects will, quite certainly, become part of Earth’s future fossil record.If such an endeavor as paleontology were ever to arise again, in a distant post-human future, how would its practitioners deal with these bizarre relics?We provide a preview, on the following pages, of just one such enigma, and how it may be resolved (or not) by our puzzled disciplinary descendants.

For the past ten years, she has translated geological narratives–and ordinary ones for Earth sciences–into extraordinary plots for the uninitiated, including the humanities. She is currently working with Jan Zalasiewicz on a play, The Petrified Museum (2024), based on the British Geological Survey (Keyworth, UK), and on a PhD project in science and technology studies looking at limestones’ agencies in extractive industry practices (2025). She regularly collaborates with researchers from the Anthropocene Working Group: The Cosmic Oasis (Oxford University Press, 2022), “The Victims of Carbon Dioxide are Starting to Appear” in Feral Atlas (2021), and The Epochs of Nature (University of Chicago Press, 2016).Jan Zalasiewicz Jan Zalasiewicz is Emeritus Professor of Paleobiology at the University of Leicester. He was formerly a field geologist and paleontologist with the British Geological Survey, involved in the geological mapping of eastern England and central Wales. His interests include Early Paleozoic fossils, notably the graptolites (a kind of extinct zooplankton), mud and mudrocks, the Quaternary Ice Ages, the nature of geological time, and the geology made by humans. In recent years, he has helped develop the concept of an Anthropocene epoch. He enjoys writing popular science articles and books, and being involved in art/science projects.Copyright © 2023 Johns Hopkins University Press and SubStance, Inc... (shrink)

We discuss the cities of the future, and how they might co-habit with the biosphere in a more mutually beneficial way. Mutualistic cities would blend with their local ecology, co-existing with the immediately available resources of water, life, energy and materials, and enhancing the biosphere so that many species can thrive, including people. Such cities can make a significant contribution to stabilizing the Earth System by sustaining and nurturing life in tune with the evolving local ecology through cyclic economies and (...) values prioritizing mutually supportive communities over economic growth. The term “mutualism” comes from biology, referring to inter-species relationships that are beneficial. Mutualistic cities would benefit human and non-human inhabitants by recycling materials, clean air, and water, and providing habitats for many species. (shrink)

Notions of the cosmos are deep-rooted in human consciousness. They are expressed in our earliest monumental constructions as explanations of the world around us and in the practices of many indigenous peoples. Here we examine the physical cosmos from the perspective of life on Earth. We note a central importance for the Earth in the vastness of space, as a planetary oasis for a highly complex and long-lived biosphere, one now being fundamentally altered by humans. We refer to other notions (...) of the cosmos that may enable us to navigate a better path for life in the Anthropocene. (shrink)

The biosphere coevolves with the atmosphere, hydrosphere and lithosphere to maintain a habitable space on Earth. Over billions of years – and despite periodic setbacks – it has evolved increasing complexity, from its microbial beginnings to the complex interactions between animals, plants, fungi and unicellular microscopic life that sustain its present state. Recently, the biosphere has been profoundly changed by humans. In part, this includes increased rates of extinction that are reminiscent of past fundamental perturbations to life. But the change (...) is even more profound, resulting from a combination of marked translocations of species beyond their indigenous ranges, overt concentration of biomass in humans and their farm animals, reconfiguration of landscape habitats and over-utilisation of ocean life, excessive appropriation of energy from the biosphere (including its fossilised component), and increasing interconnectivity between technology and life.

The Anthropocene Working Group of the Subcommission on Quaternary Stratigraphy, of the International Commission on Stratigraphy, has been active since 2009. Its primary role is to consider the Anthropocene as a potential formal addition to the Geological Time Scale. Unusual in composition because many members work in disciplines other than stratigraphic geology —the Anthropocene incorporates geological, historical, and instrumental records— it initially needed to establish whether the Anthropocene could be the basis of a valid chronostratigraphic unit. That task achieved, work (...) then focused on gathering evidence from 12 sections in different geological settings around the world, to establish which of these might be proposed as a Global boundary Stratotype Section and Point (GSSP, or ‘golden spike’) to define the Anthropocene formally. The Group aims to submit a formal proposal on this in 2023. (shrink)
