A high-resolution deuterium profile is now available along the entire European Project for Ice Coring in Antarctica Dome C ice core, extending this climate record back to marine isotope stage 20.2, ∼800,000 years ago. Experiments performed with an atmospheric general circulation model including water isotopes support its temperature interpretation. We assessed the general correspondence between Dansgaard-Oeschger events and their smoothed Antarctic counterparts for this Dome C record, which… Expand

Topics from this paper

Evidence for warmer interglacials in East Antarctic ice cores
TLDR
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. Expand
Antarctic and global climate history viewed from ice cores
TLDR
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. Expand
800,000 Years of Abrupt Climate Variability
TLDR
An 800,000-year synthetic record of Greenland climate variability based on the thermal bipolar seesaw model provides evidence for a ubiquitous association betweenipolar seesaw oscillations and glacial terminations throughout the Middle to Late Pleistocene. Expand
Regional imprints of millennial variability during the MIS 3 period around Antarctica
The climate of the last glacial Marine Isotopic Stage 3 (MIS3) period is characterized by strong millennialscale variability with a succession of DansgaardeOeschger events first identified inExpand
Local insolation changes enhance Antarctic interglacials: Insights from an 800,000-year ice sheet simulation with transient climate forcing
Abstract The Antarctic ice sheet – storing ∼27 million cubic kilometres of ice – has the potential to contribute greatly to future sea level rise; yet its past evolution and sensitivity to long-termExpand
A Record of Antarctic Climate and Ice Sheet History Recovered
Antarctica's late Cenozoic (the past ∼15 million years) climate history is poorly known from direct evidence, owing to its remoteness, an extensive sea ice apron, and an ice sheet cover over theExpand
Antarctic lakes suggest millennial reorganizations of Southern Hemisphere atmospheric and oceanic circulation
TLDR
New data from closed-basin lakes in the Dry Valleys region of East Antarctica that show high-magnitude, high-frequency oscillations in surface level during the late Pleistocene synchronous with climate fluctuations elsewhere in the Southern Hemisphere suggest a coherent Southern Hemisphere pattern of climate change on millennial time scales. Expand
Coupled ocean-land millennial-scale changes 1.26 million years ago, recorded at Site U1385 off Portugal
While a growing body of evidence indicates that North Atlantic millennial-scale climate variability extends to the Early Pleistocene, its impact on terrestrial ecosystems has not been established.Expand
Direct north-south synchronization of abrupt climate change record in ice cores using Beryllium 10
A new, decadally resolved record of the 10 Be peak at 41 kyr from the EPICA Dome C ice core (Antarctica) is used to match it with the same peak in the GRIP ice core (Greenland). This permits a directExpand
State dependence of climatic instability over the past 720,000 years from Antarctic ice cores and climate modeling
TLDR
Numerical experiments showed that climate becomes most unstable in intermediate glacial conditions associated with large changes in sea ice and the Atlantic Meridional Overturning Circulation, and model sensitivity experiments suggest that the prerequisite for the most frequent climate instability with bipolar seesaw pattern during the late Pleistocene era is associated with reduced atmospheric CO2 concentration via global cooling and sea ice formation in the North Atlantic.

Timing of millennial-scale climate change in Antarctica and Greenland during the last glacial period.
TLDR
A precise relative chronology for Greenland and West Antarctic paleotemperature is extended to 90,000 years ago, based on correlation of atmospheric methane records from the Greenland Ice Sheet Project 2 and Byrd ice cores, to provide further evidence for the operation of a "bipolar see-saw" in air temperatures and an oceanic teleconnection between the hemispheres on millennial time scales.

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. Expand

Homogeneous climate variability across East Antarctica over the past three glacial cycles
TLDR
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. Expand
A 0.5-million-year record of millennial-scale climate variability in the north atlantic

Long, continuous, marine sediment records from the subpolar North Atlantic document the glacial modulation of regional climate instability throughout the past 0.5 million years, which characterizes nearly all observed climate states. Expand
