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. The succession of changes through each climate cycle and termination was similar, and atmospheric and climate properties oscillated between stable bounds. Interglacial periods differed in temporal evolution and duration. Atmospheric concentrations of carbon dioxide and methane correlate well with… 

Orbital and Millennial Antarctic Climate Variability over the Past 800,000 Years

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

Antarctic and global climate history viewed from ice cores

A growing network of ice cores reveals the past 800,000 years of Antarctic climate and atmospheric composition, showing tight links among greenhouse gases, aerosols and global climate on many timescales and the extraordinary differences between the composition of the authors' present atmosphere and its natural range of variability as revealed in the ice core record.

Eight glacial cycles from an Antarctic ice core

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.

Timing of Atmospheric CO2 and Antarctic Temperature Changes Across Termination III

The sequence of events during Termination III suggests that the CO2 increase lagged Antarctic deglacial warming by 800 ± 200 years and preceded the Northern Hemisphere deglaciation.

Four climatic cycles based on ice core data from deep drilling at the Vostok station, Antarctica

Abstract The results of many years of Russian‐French‐American studies of an ice core from a borehole in central Antarctica to a depth of 3310 m are presented. The data encompass four climatic cycles

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 and Climate on Millennial Time Scales During the Last Glacial Period

Evidence from marine sediment proxies indicates that CO2 concentration rose most rapidly when North Atlantic Deep Water shoaled and stratification in the Southern Ocean was reduced, implying a strong connection to Southern Ocean processes.

Abrupt CO2 release to the atmosphere under glacial and early interglacial climate conditions

A record of atmospheric carbon dioxide concentrations retrieved from the European Project for Ice Coring in Antarctica Dome C ice core shows that pronounced carbon dioxide jumps occurred during both cold and warm periods between 330,000 and 450,000 years ago, revealing pervasive features of the carbon cycle that can occur during interglacial climate conditions.

The changes in isotope composition and accumulation of snow at Vostok station, East Antarctica, over the past 200 years

Abstract High-resolution records of isotope composition (δD) and accumulation of snow have been obtained from 10–12m deep snow pits dug in the vicinity of Vostok station during the 1979/80 and



Ice core records of atmospheric CO2 around the last three glacial terminations

Air trapped in bubbles in polar ice cores constitutes an archive for the reconstruction of the global carbon cycle and the relation between greenhouse gases and climate in the past, and high-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased after the warming of the last three deglaciations.

It is shown here that two of the most prominent North Atlantic events-the rapid warming that marks the end of the last glacial period and the Bolling/Allerod-Younger Dryas oscillation-are also recorded in an ice core from Taylor Dome, in the western Ross Sea sector of Antarctica.

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

Simulated influence of carbon dioxide, orbital forcing and ice sheets on the climate of the Last Glacial Maximum

A coupled atmosphere–ocean–sea-ice model is used to investigate the climate of the Last Glacial Maximum (∼21,000 years ago) and the relative climate-forcing effects of atmosphere CO2, the Earth's

A 150,000-year climatic record from Antarctic ice

During much of the Quaternary, the Earth's climate has undergone drastic changes most notably successive glacial and interglacial episodes. The past 150 kyr includes such a climatic cycle: the last

The Dole effect over the last two glacial-interglacial cycles

Detailed measurements of δ 18 O of atmospheric oxygen performed on air trapped in the Vostok ice cores (Antarctica) are used to extend the record of the Dole effect over two climatic cycles (back to

Ice-core record of atmospheric methane over the past 160,000 years

Methane measurements along the Vostok ice core reveal substantial changes over the past 160,000 years which are associated with climate fluctuations. These results point to changes in sources of

Synchronous changes in atmospheric CH4 and Greenland climate between 40 and 8 kyr BP

ICE-CORE reconstructions of atmospheric methane concentrations for the past 220 kyr have revealed large variations associated with different climatic periods1–4. But the phase relationship between

Atmospheric CO2 concentration and millennial-scale climate change during the last glacial period

The analysis of air bubbles trapped in polar ice has permitted the reconstruction of past atmospheric concentrations of CO2 over various timescales, and revealed that large climate changes over tens

Vostok ice core: a continuous isotope temperature record over the last climatic cycle (160,000 years)

A continuous deuterium profile along the 160,000-year Vostok ice core (Antarctica) is interpreted in terms of atmospheric temperature changes. This climatic record is the awaited terrestrial
