The Anthropocene epoch, while rejected as an official unit of the geological time scale in 2024, remains a widely used concept and descriptor of Earth’s geological history from the mid-20th century to the present day and beyond, with planetary functions increasingly departing from Holocene norms. Quaternary science must account for this recent, unprecedented and planetary-scale change to remain relevant to wider society. Accumulated fossil-fuel-derived carbon dioxide in the oceans and atmosphere has already ensured that a changed planetary state will continue for hundreds of millennia, and its novel geological signature is indelible, with the biosphere irreversibly altered. But the Anthropocene epoch is more than this, representing a new way to engage with the humanities, social and educational sciences, law, politics and many other branches of enquiry and policy-making. We invite presentations on all aspects of the Anthropocene epoch, and on its transition from the Holocene.
