“…The relationship between the magnitude of the drivers (and the rate at which they change) and the responses of the Earth System to these drivers is complex, has been examined in a large body of literature, lies at the heart of contemporary Earth System science, and is not amenable to simple mathematical analysis. Absolute rates of change in the climate system (e.g., CO 2 and temperature rise; Lear et al, 2020) and in the biosphere (IPBES, 2019) are generally highest today. When viewed in terms of resource utilization and corresponding outflows of wastes and emissions, the Earth System has undergone significant upturns in metabolism around 1950 and again from the beginning of the 21 st century (Krausmann et al, 2018).…”

The Anthropocene was conceptualized in 2000 to reflect the extensive impact of human activities on our planet, and subsequent detailed analyses have revealed a substantial Earth System response to these impacts beginning in the mid-20 th century. Key to this understanding was the discovery of a sharp upturn in a multitude of global socio-economic indicators and Earth System trends at that time; a phenomenon termed the 'Great Acceleration'. It coincides with massive increases in global human-consumed energy and shows the Earth System now on a trajectory far exceeding the earlier variability of the Holocene Epoch, and in some respects the entire Quaternary Period. The evaluation of geological signals similarly shows the mid-20 th century as representing the most appropriate inception for the Anthropocene. A recent mathematical analysis has nonetheless challenged the significance of the original Great Acceleration data. We examine this analytical approach and reiterate the robustness of the original data in supporting the Great Acceleration, while emphasizing that intervals of rapid growth are inevitably time-limited, as recognised at the outset. Moreover, the exceptional magnitude of this growth remains undeniable, reaffirming the centrality of the Great Acceleration in justifying a formal chronostratigraphic Anthropocene at the rank of series/epoch.

“…Mitigation and adaptation strategies to manage these changes are essential. Therefore, understanding past periods of climate change recorded in the Earth's geology is critical (Lee et al, 2018;Lear et al, 2020). Thus, articles concerning the analyses of geological records relevant to climate change may draw interest from geologists and public communities.…”

Episodes has published many excellent articles on relevant, provocative, and interesting geological themes in Special Issues (SIs). The IUGS Publications Committee and editorial team have endeavored to publish SIs regularly; however, it has remained inconsistent (Table 1). The themes of the Sis published in this journal include natural stones, asbestos, the geodynamic evolution of the Indian subcontinent, forensic geology, the great mineral fields of Africa, ophiolites, global heritage stone resources, catastrophic tsunamis, geology of the Oceania, and Nordic geoscience (see Table 1). Each SI contains 7 to 43 articles with a mean of 17. A Google Scholar search revealed that currently, each SI has been cited 12 to 1,099 times (mean = 252). Each article in the Sis has been cited 1.71 to 37.89 times. The SIs celebrating the International Geological Congress (IGC), held every four years, were a great success with regard to the citations by other studies.

“…To summarize, there is broad consensus within the geoscience and climate science communities that maintaining the Earth's polar ice caps is critical for the persistence of the relatively stable climates and shorelines that support modern ecosystems and human civilization (Sigmond et al 2018;Vousdoukas et al 2018;Westerhold et al 2020, Lear et al 2021). In the starkest of terms, we risk raising the concentration of CO2 in the Earth's atmosphere above 450 ppm at our peril (Sherwood et al 2020).…”
