The Case for the Anthropocene Epoch Is Stronger Than the Case for the Holocene Epoch

Earth's Future, Volume 13, Issue 5, May 2025.
Abstract The recommendation that the Anthropocene be denoted as a geological epoch was recently rejected by the International Union of Geological Sciences. Here, we compare the scientific rationales presented for the Anthropocene, the Holocene and the six other epochs in the Cenozoic Era: the Pleistocene, the Pliocene, the Miocene, the Oligocene, the ...

Glacial‐Interglacial and Millennial‐Scale Changes in Nitrous Oxide Emissions Pathways and Source Regions

Global Biogeochemical Cycles, Volume 39, Issue 5, May 2025.
Abstract During the transition from the Last Glacial Maximum (LGM) to the Holocene, the atmospheric N2O mole fraction increased by 80 nmol mol−1. Using ice core measurements of N2O isotopomer ratios, we show that this increase was driven by increases in both nitrification and denitrification, with the relative partitioning between both production ...

The Role of Ballasting, Seawater Viscosity and Oxygen‐Dependent Remineralization for Export and Transfer Efficiencies in the Global Ocean

Global Biogeochemical Cycles, Volume 39, Issue 5, May 2025.
Abstract The particulate organic carbon (POC) flux from the euphotic zone to the deep ocean is central to the biological carbon pump. It is typically evaluated using “export efficiency” and “transfer efficiency,” which reflect POC formation and sinking and carbon sequestration efficiency in the ocean's interior, respectively.
