The Anthropocene as a conceptual tool for education
In a world where facts are contested, the conceptual tool of the Anthropocene epoch – that is, the dramatic and clearly demonstrable ways humans have changed the Earth system trajectory since the mid-20th century – provides real value for society in general and for education in particular. As a unifying concept, it helps us (a) understand the transformed bioclimatic conditions in which we live, (b) appreciate how fragile they are, how rapidly the…
Understanding the end of the Holocene
This is a statistical analysis of several time series to find the best evidence to determine when the Holocene ended. We utilize nonparametric statistical methods (which are model free) to determine structural breaks on whether the cumulative human impacts on land, air and oceans are indicative of the end of the Holocene Epoch. It is shown that the use of fossil fuels was the dominant factor in achieving high standards of living, and increased li…
Response to Damianos—Anthropocene angst
Damianos provides his views on the significance of the March 2024 decision by the International Commission on Stratigraphy (ICS) to reject the proposal of the Anthropocene Working Group (AWG), the body we represent, to formalize the Anthropocene as a series/epoch of the Geological Time Scale. He draws upon ‘four years of ethnographic observation’ of the AWG, over which time this body provided him with access to its meetings and discussions. Given…
Humans and the Great Lakes— Anthropogenic Impact and the Search for the “Anthropocene Golden Spike
Since Paul Crutzen introduced the term Anthropocene twenty-five years ago, it has become conflated with the concept of anthropogenic impact, which is globally diachronous. Crutzen introduced the term as a geological epoch to reflect the altered state of the Earth System, however, signifying an end to the Holocene Epoch whose relative stability fostered the evolution of human culture. The culmination of a fifteen-year effort to formally define the…
High-resolution analysis of the varved succession at Crawford lake across the base of the proposed Crawfordian stage and Anthropocene series
Four years after the Anthropocene Working Group (AWG) voted to work toward defining the Anthropocene series/epoch with a base in the mid-20th C, the varved sediments of Crawford Lake (Milton, ON, Canada) were selected as the Global boundary Stratotype Section and Point (GSSP) candidate. The initial major rise in activity of 239 + 240 Pu had been selected as the primary chronostratigraphic marker to define the base of the Anthropocene, but the pre…
The varved succession of Crawford Lake, Milton, Ontario, Canada as a candidate Global boundary Stratotype Section and Point for the Anthropocene series
An annually laminated succession in Crawford Lake, Ontario, Canada is proposed for the Global boundary Stratotype Section and Point (GSSP) to define the Anthropocene as a series/epoch with a base dated at 1950 CE. Varve couplets of organic matter capped by calcite precipitated each summer in alkaline surface waters reflect environmental change at global to local scales. Spheroidal carbonaceous particles and nitrogen isotopes record an increase in…
Siliceous algae response to the “Great Acceleration” of the mid-20th century in Crawford Lake (Ontario, Canada)
Diatom and chrysophyte assemblages from varved sediments of meromictic Crawford Lake, Ontario record major environmental changes resulting from spatially broadening anthropogenic environmental stressors related to the “Great Acceleration” in the mid-20th century. Biannual assessment of diatom and chrysophyte assemblages over the last ~200 years allowed for rate of change analysis between adjacent samples that increased substantially during the mi…
Minimum limiting deglacial ages for the out-of-phase Saginaw Lobe of the Laurentide Ice Sheet using optically stimulated luminescence (OSL) and radiocarbon methods
Twenty-four new optically stimulated luminescence (OSL) and radiocarbon ages from sediment cores in nine lakes associated with the Shipshewana and Sturgis moraines in northern Indiana and southern Michigan estimate when recession of the Saginaw Lobe of the Laurentide Ice Sheet was underway in the southern Great Lakes region, USA. Average OSL ages of 23.4 ± 2.2 ka for the Shipshewana Moraine and 19.7 ± 2.2 ka for the Sturgis Moraine are considered…
