The recent completion of drilling at Vostok station in East Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacial–interglacial cycles.…

It is suggested that the interplay between obliquity and precession accounts for the variable intensity of interglacial periods in ice core records.

It is suggested that changes in the strength of tropical methane sources and sinks (wetlands, atmospheric oxidation) controlled the atmospheric methane budget, with an additional source input during major terminations as the retreat of the northern ice sheet allowed higher methane emissions from extending periglacial wetlands.
Asynchrony of Antarctic and Greenland climate change during the last glacial period

A central issue in climate dynamics is to understand how the Northern and Southern hemispheres are coupled during climate events. The strongest of the fast temperature changes observed in Greenland…

An undisturbed climate record from a North Greenland ice core, which extends back to 123,000 years before the present, within the last interglacial period, shows a slow decline in temperatures that marked the initiation of the last glacial period.

It is concluded that a pronounced 0.3 per mil decrease in δ13Catm during the early deglaciation can be best explained by upwelling of old, carbon-enriched waters in the Southern Ocean.

The European Project for Ice Coring in Antarctica Dome ice core from Dome C (EDC) has allowed for the reconstruction of atmospheric CO2 concentrations for the last 800,000 years. Here we revisit the…
Eight glacial cycles from an Antarctic ice core

- 10 June 2004
The recovery of a deep ice core from Dome C, Antarctica, that provides a climate record for the past 740,000 years is reported, suggesting that without human intervention, a climate similar to the present one would extend well into the future.
Variations in atmospheric methane concentration during the Holocene epoch
- T. Blunier, J. Chappellaz, J. Schwander, B. Stauffer, D. Raynaud
- Environmental Science, GeographyNature
- 2 March 1995
RECORDS of the variation in atmospheric methane concentration have been obtained from ice cores for the past 1,000 years and for the period 8,000–220,000 yr BP (refs 1–4), but data for the…
