Human activity is leaving a pervasive and persistent signature on Earth. Vigorous debate continues about whether this warrants recognition as a new geologic time unit known as the Anthropocene. We review anthropogenic markers of functional changes in the Earth system through the stratigraphic record. The appearance of manufactured materials in sedi...
Stratigraphy provides insights into the evolution and dynamics of the Earth System over
its long history. With recent developments in Earth System science, changes in Earth System dynamics can now be observed directly and projected into the near future. An integration of the two approaches provides powerful insights into the nature and significance...
(Excerpts from text) … Reefs as ecosystems have shown pronounced evolutionary changes as well as marked adaptation to distinct but changing ecological reef settings, and they hence were prone to reflect large-scale synchronous global impacts as well as regional ecological changes. Therefore, extensive episodes of global reef decline during major Ea...
Growth in fundamental drivers—energy use, economic productivity and population—can provide quantitative indications of the proposed boundary between the Holocene Epoch and the Anthropocene. Human energy expenditure in the Anthropocene, ~22 zetajoules (ZJ), exceeds that across the prior 11,700 years of the Holocene (~14.6 ZJ), largely through combus...
The "Great Acceleration" beginning in the mid-20th century provides the causal mechanism of the Anthro-pocene, which has been proposed as a new epoch of geological time beginning in 1952 CE. Here we identify key parameters and their diagnostic palaeontological signals of the Anthropocene, including the rapid breakdown of discrete biogeographical ra...

From the Abstract: The technosphere sensu Peter Haff [12] has auton- omous qualities, being not so much human-directed as incorporating dependent, strongly divided human soci- eties, while parasitizing its parent biosphere for energy and materials. By far the most recent and rapidly evolving of Earth’s ‘spheres’, it is also the most unsta- ble, rec...
From the Abstract: The Anthropocene is a particularly powerful con- ceptual tool, and encapsulates the complex intercon- nectivity of all the ‘-spheres’ on this planet. It quickly became a key framing concept for Earth System re- searchers. From this, and from its subsequent geologi- cal analysis, it grew to spark off considerable cross- disciplina...
From the Abstract: The biogeophysical and socio-political knowledge of the Anthropocene, while transforming our understanding of the Earth System, is also renewing our understanding of human existence and raising questions about education at a time when profound existential challenges are looming. These issues are now inextricably linked. Human exi...
We synthesize research from complementary scientific fields to address the likely future extent and duration of the proposed Anthropocene epoch. Intensification of human-forced climate change began from about 1970 onwards with steepening increases in greenhouse gases, ocean acidification, global temperature and sea level, along with ice loss. The r...
Increasing human interactions with the biosphere over tens of millennia have left a fossil record that shows the growing geographical spread and technological sophistication of humans evident in patterns of extinction and domestication of the landscape and its plants and animals. Here, we focus on the "Great Acceleration" of the mid-20th century (e...
Applying the basic principles of carbon chemistry and physics, along with a comprehensive understanding of past climate change, Steffen and colleagues confirmed in the Proceedings of the National Academy of Sciences 115, in 2018, that fossil fuel usage and resulting carbon emissions will cause substantial global warming into future millennia. The c...
A common sense: The Anthropocene was originally understood by Crutzen as not only representing humanity’s influence on Earth’s geological record (he was well aware of earlier anthropogenic impacts), but also reflecting a system with physical characteristics that had, since widespread industrialization, departed from the prolonged, relatively stable...
Introduction: Geology as an organized science is little more than two centuries old (Rudwick 2014), a newcomer compared with academic disciplines such as mathematics, philosophy - and indeed ethics. It has been a practical newcomer, too. Even among its 18th-century roots, references to resources, and their exploitation, are common. The Comte de Buf...

Over the past weeks, the media have been full of reports and opinion pieces on the decision of the SQS/ICS/IUGS, i.e. the committees responsible for formalising an Anthropocene epoch for the geological chronostratigraphic time chart. To the surprise of many, these committees now did not want to open a new chapter in the book of Earth History. Some...
The Anthropocene Working Group (AWG) has concluded that the Anthropocene represents geological reality and should be linked with the plethora of stratigraphic proxies that initiate or show marked perturbations at around the 1950s, and should be defined using a Global boundary Stratotype Section and Point (GSSP). We propose formalizing the Anthropoc...

This is the Executive Summary of a report produced by the membership of the Anthropocene Working Group as part of a submission to the Subcommission on Quaternary Stratigraphy to seek formalisation of the Anthropocene as an epoch of geological time. It summarises the content of two reports and their associated appendices which provide a background t...
The Anthropocene as a prospective new, ongoing series/epoch must be defensible against all relevant concerns.

About the contents: The long time of Earth history was untamed until "geo-earthlings" divided it into sequences and tied it into a rigid corset, the chronostratigraphic map of Earth history. This scientific graphic novel then sheds light on how Earth history periods differ and how they can be defined. Since 1950, human impact on the Earth system ha...

Swindles et al. (2023) correctly point out that there are many conceptions of the ‘Anthropocene’ in use, and they argue that this flexibility in terminology is desirable. We agree that the multiple uses of this term have stimulated much scholarly debate, but we contend that precision in terminology is far more desirable than vagueness, and promotes...
Der enorme Fußabdruck der Menschheit auf die Biosphäre und das gesamte Erdsystem ist mittlerweile global nachweisbar. So sind die eisfreien Regionen der festen Erde schon zu ca. 75% keine Urnatur mehr. Landwirtschaftlich genutzte Flächen haben bei weitem den höchsten Anteil daran1. 96% der (kohlenstoff-basierten) Biomasse aller Säugetiere fallen au...
Merritts et al. (2023) misrepresent Paul Crutzen’s Anthropocene concept as encompassing all significant anthropogenic impacts, extending back many millennia. Crutzen’s definition reflects massively enhanced, much more recent human impacts that transformed the Earth System away from the stability of Holocene conditions.
His concept of an epoch (henc...
Event stratigraphy is used to help characterise the Anthropocene as a chronostratigraphic concept, based on analogous deep-time events, for which we provide a novel categorization.

We examine three distinctive biostratigraphic signatures of humans associated with hunting and gathering , landscape domestication and globalization. All three signatures have significant fossil records of regional importance that can be correlated interregionally and help describe the developing pattern of human expansion and appropriation of reso...
The extensive array of mid-20 th century stratigraphic event signals associated with the 'Great Acceleration' enables precise and unambiguous recognition of the Anthropocene as an epoch/series within the Geological Time Scale. A mid-20 th century inception is consistent with Earth System science analysis in which the Anthropocene term and concept a...
The Anthropocene defined as an epoch/series within the Geological Time Scale, and with an isochronous inception in the mid-20th century, would both utilize the rich array of stratigraphic signals associated with the Great Acceleration and align with Earth System science analysis from where the term Anthropocene originated. It would be stratigraphic...

The Anthropocene was conceptualized in 2000 to reflect the extensive impact of human activities on our planet, and subsequent detailed analyses have revealed a sub- stantial Earth System response to these impacts begin- ning in the mid-20th century.

The term Anthropocene initially emerged from the Earth System science community in
the early 2000s, denoting a concept that the Holocene Epoch has terminated as a consequence of human activities. First associated with the onset of the Industrial Revolution, it was then more closely linked
with the Great Acceleration in industrialization and globali...

Earth history is too often misused for wrong excuses like „geology is stronger than us“, „climate has always changed“, or „coral reefs have died out several times but always recovered“, in order to relativise or even to reject the need of human behavioural change.

Questions
Question (1)
This is the comic version of a science-policy-advise flagship report from the German Advisory Council on Global Change (WBGU), which is now also available in english language. You may order a free copy (but better hurry up via http://www.wbgu.de/en ). We prepared the (german) book as part of a communication research project, to find out whether the multilevel-multimodal format of a science comic might work for better negotiating complex, systemic, transdisciplinary topics such as climate change issues, e.g. in school education. The results in Germany have been very stimulating. However, does this book, based on protagonists from Germany, also work for other countries? Any comment on the english version of the book, be it public or personal to me, is highly welcome (book website with more informations, mostly in german, is http://www.die-grosse-transformation.de)
