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.

AMOC Modulates Ocean Heat Content During Deglaciations Geophysical Research Letters, 2025 (Ref: 17241)
Authors:
Grimmer M.Baggenstos D.Schmitt J.Krauss F.Shackleton S.Severinghaus J.P.Fischer H.
Category 1: Peer-reviewed literature

During deglaciations, Earth takes up vast amounts of energy, about half of which heats the global ocean. Thus, ocean heat content (OHC) is a key metric to assess Earth's energy budget.

Laser-induced sublimation extraction for centimeter-resolution multi-species greenhouse gas analysis on ice cores. Atmospheric Measurement Techniques, 2023 (Ref: 17089)
Authors:

Category 1: Peer-reviewed literature

Precision, accuracy, and temporal resolution are key to making full use of atmospheric trace gas records in ice cores. These aspects will become especially crucial for ice cores that aim to extend the ice core record to the last 1.5?Myr, i.e., across the Mid-Pleistocene Transition…
