Measurements of the CO2 concentration of air trapped in Greenland Ice Sheet Project Two ice show an increase from approximately 190 ppm to 270 ppm during the 8000 years between the end of the last glacial maximum and the beginning of the Holocene. This increase is in agreement with other parallel records from both Greenland and Antarctica, although the GISP2 data exhibit considerable variability over periods as small as 50–100 years and show that CO2 can be affected by processes occurring… 
The CO2 concentration of air trapped in Greenland Ice Sheet Project 2 ice formed during periods of rapid climate change
The CO2 content of air occluded in Greenland Ice Sheet Project 2 (GISP2) ice formed over two separate intervals of rapidly changing climate, centered at approximately 46 and 63 kyr B. P., is as much
Reconstructing past atmospheric CO2 concentration based on ice-core analyses: open questions due to in situ production of CO2 in the ice
Abstract Analysis of air extracted from bubbles of polar ice showed the anthropogenic increase of atmospheric CO2 concentration during the past few hundred years (preindustrial concentration 280
A record of atmospheric CO2 during the last 40,000 years from the Siple Dome, Antarctica ice core
[1] We have measured the CO2 concentration of air occluded during the last 40,000 years in the deep Siple Dome A (hereafter Siple Dome) ice core, Antarctica. The general trend of CO2 concentration
Atmospheric CO2 concentrations over the last glacial termination.
The similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are located, also had substantial effects on atmospheric CO2 concentrations.
Atmospheric CO2 variations over the last three glacial’interglacial climatic cycles deduced from the Dome Fuji deep ice core, Antarctica using a wet extraction technique
A deep ice core drilled at Dome Fuji, East Antarctica was analyzed for the CO2 concentration using a wet extraction method in order to reconstruct its atmospheric variations over the past 320 kyr,
Atmospheric CO2 over the last 1000 years: A high‐resolution record from the West Antarctic Ice Sheet (WAIS) Divide ice core
We report a decadally resolved record of atmospheric CO2 concentration for the last 1000 years, obtained from the West Antarctic Ice Sheet (WAIS) Divide shallow ice core. The most prominent feature
Record of cosmogenic in situ produced 14C in Vostok and Taylor Dome ice samples: Implications for strong role of wind ventilation processes
We present results of studies of in situ cosmogenic 14 C in several ice samples from the Vostok and Taylor Dome cores, spanning the time intervals of 20 and 11 k.y. B.P., respectively. The results
Stomatal evidence for a decline in atmospheric CO2 concentration during the Younger Dryas stadial: a comparison with Antarctic ice core records
A recent high‐resolution record of Late‐glacial CO2 change from Dome Concordia in Antarctica reveals a trend of increasing CO2 across the Younger Dryas stadial (GS‐1). These results are in good

CO2 record in the Byrd ice core 50,000–5,000 years bp
The analysis of air in polar ice cores revealed 30% lower CO2 values during glacial periods than during interglacial periods. At present this is confirmed by results from six different ice cores, two
Processes affecting the CO2 concentrations measured in Greenland ice
Detailed CO 2 measurements on ice cores from Greenland and Antarctica show different mean CO 2 concentrations for samples at the same gas age. The deviation between Antarctic and Greenland CO 2
CO2 measurements from polar ice cores: more data from different sites
Air in the bubbles of polar ice has in principal the same composition as the atmospheric air at the time of ice formation. Based on this relationship, an increase in atmospheric CO 2 since the
Initial measurements of CO2 concentrations (1530 to 1940 AD) in air occluded in the GISP 2 Ice Core from central Greenland
Initial measurements of CO2 in the air of bubbles in the GISP 2 (Greenland Ice Sheet Project 2) ice core were performed using a dry extraction technique and tunable diode laser absorption
CO2 evolution during the last millennium as recorded by Antarctic and Greenland ice
In order to study in detail the pre-industrial CO 2 level (back to about 900 AD) and its temporal variations, several ice cores from Greenland and Antarctica were analysed in two laboratories, and
Ice core sample measurements give atmospheric CO2 content during the past 40,000 yr

A natural artefact in Greenland ice‐core CO2 measurements
Paleoatmospheric concentrations of CO 2 over the last ice ages have been revealed by ice-core analysis. According to the time period (ice age or interglacial) and the hemisphere considered, the ice
Carbon isotope composition of atmospheric CO2 during the last ice age from an Antarctic ice core
