TL;DR: In this paper, the authors used a high-resolution deuterium-excess record from West Antarctica to show that the latitude of the mean moisture source for Antarctic precipitation changed in phase with abrupt shifts in Northern Hemisphere climate, and significantly before Antarctic temperature change.
Journal ArticleDOI
The δ18O of atmospheric O2 from air inclusions in the Vostok Ice Core: Timing of CO2 and ice volume changes during the penultimate deglaciation
TL;DR: In this paper, the isotopic composition (δ18O) of atmospheric O2 trapped in the Vostok ice core was used as a proxy for the seawater and hence ice volume.
Journal ArticleDOI
Comparison of the microbial diversity at different depths of the GISP2 Greenland ice core in relationship to deposition climates
TL;DR: The observed differences in microbial diversity patterns support the idea that local climate conditions and global atmospheric circulations at different time periods have influenced the origin and composition of the microbial populations preserved at different depths of Greenland ice.
Journal ArticleDOI
Carbon and hydrogen isotopic composition of methane over the last 1000 years
John A. Mischler,Todd Sowers,Richard B. Alley,M. O. Battle,Joseph R. McConnell,Logan Mitchell,Trevor Popp,E. D. Sofen,M. K. Spencer +8 more
TL;DR: In this article, a broad range of source scenarios using a simple box model was identified to identify histories consistent with the constraints of the CH4 concentration and isotope data from 990-1730 CE.
Journal ArticleDOI
Constraints on the Late Holocene Anthropogenic Contribution to the Atmospheric Methane Budget
TL;DR: High-resolution, high-precision ice core methane concentration records from Greenland and Antarctica are presented and used to construct a high-resolution record of the methane inter-polar difference (IPD), showing that LPIH emissions increased primarily in the tropics, with secondary increases in the subtropical Northern Hemisphere.
