The Antarctic Vostok ice core provided compelling evidence of the nature of climate, and of climate feedbacks, over the past 420,000 years. Marine records suggest that the amplitude of climate variability was smaller before that time, but such records are often poorly resolved. Moreover, it is not possible to infer the abundance of greenhouse gases in the atmosphere from marine records. Here we report the recovery of a deep ice core from Dome C, Antarctica, that provides a climate record for… 

Recent Antarctic Peninsula warming relative to Holocene climate and ice-shelf history

Warming for several centuries rendered ice shelves on the northeastern Antarctic Peninsula vulnerable to collapse, and continued warming to temperatures that now exceed the stable conditions of most of the Holocene epoch is likely to cause ice-shelf instability to encroach farther southward along the Antarctic Peninsula.

One-to-one coupling of glacial climate variability in Greenland and Antarctica.

Precise knowledge of the phase relationship between climate changes in the two hemispheres is a key for understanding the Earth's climate dynamics. For the last glacial period, ice core studies1, 2

The later parts of the Quaternary are of particular importance for assessing out ability to understand the future operation of the Earth because the main boundary conditions are similar to those of

One-to-one coupling of glacial climate variability in Greenland and Antarctica

A glacial climate record derived from an ice core from Dronning Maud Land, Antarctica, is presented which represents South Atlantic climate at a resolution comparable with the Greenland ice core records and shows a one-to-one coupling between all Antarctic warm events and Greenland Dansgaard–Oeschger events by the bipolar seesaw.

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.

Recent changes in a remote Arctic lake are unique within the past 200,000 years

A lake sediment sequence from the Canadian Arctic is presented that records warm periods of the past 200,000 years, including the 20th century, and provides a perspective on recent changes in the Arctic.

Evidence for warmer interglacials in East Antarctic ice cores

It is shown that for warmer interglacial periods the relationship between temperature and the isotopic signature varies among ice core sites, and that therefore the conversions must be nonlinear for at least some sites.

The Climate of the Antarctic Peninsula during the Twentieth Century: Evidence from Ice Cores

The Antarctic Peninsula (AP) is a region of special climatological interest. The late twentieth century has been a period of warming surface temperatures, enhanced mass loss from melting glaciers and

State of the Antarctic and Southern Ocean climate system

This paper reviews developments in our understanding of the state of the Antarctic and Southern Ocean climate and its relation to the global climate system over the last few millennia. Climate over



Homogeneous climate variability across East Antarctica over the past three glacial cycles

An isotopic profile from a core drilled at Dome Fuji indicates that Antarctic climate is essentially homogeneous at the scale of the East Antarctic Plateau, possibly as a consequence of the symmetry of the plateau and the adjacent ocean.

Climate and atmospheric history of the past 420,000 years from the Vostok ice core, Antarctica

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.

A new 27 ky high resolution East Antarctic climate record

The ice core recently drilled at the Dome Concordia site on the East Antarctic plateau provides a new high resolution isotope record covering part of the last glacial, the last transition and the

Extending The Ice Core Record Beyond Half A Million Years

Ice cores have been a crucial source of information about past changes in the climate and atmosphere. The Vostok ice core from Antarctica has provided key global change data sets extending 400,000

Hemispheric roles of climate forcings during glacial‐interglacial transitions as deduced from the Vostok record and LLN‐2D model experiments

The Vostok ice contains fingerprints of atmospheric greenhouse trace gases, Antarctic temperature, Northern Hemisphere temperature, and global ice volume/sea level changes during the last

Modeling the evolution of Antarctic ice sheet over the last 420,000 years: Implications for altitude changes in the Vostok region

A new thermomechanical three-dimensional model designed to simulate the evolution of the Antarctic ice sheet over long time periods is presented. This model incorporates the various types of ice flow

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.

Glacial to Holocene implications of the new 27000-year dust record from the EPICA Dome C (East Antarctica) ice core

Abstract. Insoluble dust concentrations and volume-size distributions have been measured for the new 581 m deep Dome C-EPICA ice core (Antarctica). Over the 27000 years spanned by the record,
