Glacial-Interglacial and Millennial-Scale Changes in Nitrous Oxide Emissions Pathways and Source Regions Global Biogeochemical Cycles, 2025 (Ref: 17320)
Authors:
Menking J.A.Lee J.E.Brook E.J.Schmitt J.Soussaintjean L.Fischer H.Kaiser J.Rice A.
Category 1: Peer-reviewed literature

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…

Using high-precision ice core measurements of CO2, ?13C-CO2, CH4, and N2O, this study provides carbon isotope constraints on a sizeable, centennial-scale CO2 jump at the onset of Marine Isotope Stage 9 (MIS 9). The very end of the Heinrich stadial (HS) characterizing Termination IV (T-IV, ca.

Abrupt changes in biomass burning during the last glacial period Nature, 2025 (Ref: 17285)
Authors:
Riddell-Young B.Lee J.Brook E.Schmitt J.Fischer H.Bauska T.Menking J.Iseli R.Clark J.
Category 1: Peer-reviewed literature

Understanding the causes of past atmospheric methane (CH4) variability is important for characterizing the relationship between CH4, global climate and terrestrial biogeochemical cycling.
