Greenland climate variability for the past 800,000 years was inferred from the Antarctic ice-core temperature record. We constructed an 800,000-year synthetic record of Greenland climate variability based on the thermal bipolar seesaw model. Our Greenland analog reproduces much of the variability seen in the Greenland ice cores over the past 100,000 years. The synthetic record shows strong similarity with the absolutely dated speleothem record from China, allowing us to place ice core records… 

State dependence of climatic instability over the past 720,000 years from Antarctic ice cores and climate modeling

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.

Abrupt glacial climate shifts controlled by ice sheet changes

It is shown, by using a comprehensive fully coupled model, that gradual changes in the height of the Northern Hemisphere ice sheets (NHISs) can alter the coupled atmosphere–ocean system and cause rapid glacial climate shifts closely resembling DO events.

A 0.6 million year record of millennial‐scale climate variability in the tropics

A ~600 kyr long scanning X‐ray fluorescence record of redox variability from the Cariaco Basin, Venezuela, provides insight into rapid climate change in the tropics over the past five

Persistent millennial-scale climate variability in the eastern tropical North Pacific over the last two glacial cycles

High-resolution sediment records from the eastern tropical North Pacific (ETNP) spanning the last ~240 ka B.P. were studied to document the nature of millennial-scale climatic events in the tropical

700,000 years of tropical Andean glaciation

Our understanding of the climatic teleconnections that drove ice-age cycles has been limited by a paucity of well-dated tropical records of glaciation that span several glacial–interglacial

The Asian monsoon over the past 640,000 years and ice age terminations

Observations indicate that insolation, in part, sets the pace of the occurrence of millennial-scale events, including those associated with terminations and ‘unfinished terminations’.

Persistent orbital influence on millennial climate variability through the Pleistocene

Abundant evidence from marine, ice-core and terrestrial records demonstrates that Earth’s climate has experienced co-evolution of orbital- and millennial-scale variability through the Pleistocene.



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.

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.

Phase relationships between millennial‐scale events 64,000–24,000 years ago

A core recovered on the Iberian margin off southern Portugal can be correlated with Greenland ice cores using oxygen isotope variability in planktonic foraminifera which closely matches the ice core

Timing of millennial-scale climate change in Antarctica and Greenland during the last glacial period.

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.

Phase relationships between Antarctic and Greenland climate records

Abstract Comparison of climate records from Antarctic and Greenland ice cores shows that the two regions respond asynchronously during millennial-scale climate changes. the apparent out-of-phase

Orbital and millennial-scale features of atmospheric CH4 over the past 800,000 years

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.

Correlations between climate records from North Atlantic sediments and Greenland ice

OXYGEN isotope measurements in Greenland ice demonstrate that a series of rapid warm-cold oscillations—called Dansgaard–Oeschger events—punctuated the last glaciation1. Here we present records of sea

Amplitude variations of 1470‐year climate oscillations during the last 100,000 years linked to fluctuations of continental ice mass

We describe amplitude variations of a 1470‐year (y) signal in the oxygen‐isotope record from the GISP2 ice‐core as a function of continental ice mass as recorded in sea‐level variations. The 1470‐y

Millennial and sub-millennial scale climatic variations recorded in polar ice cores over the last glacial period

Abstract. Since its discovery in Greenland ice cores, the millennial scale climatic variability of the last glacial period has been increasingly documented at all latitudes with studies focusing

Four Climate Cycles of Recurring Deep and Surface Water Destabilizations on the Iberian Margin

Proxies of sea surface temperature and water mass distribution, as well as relative biomarker content, demonstrate that this typical north-south coupling was pervasive for the cold phases of climate during the past 420,000 years.
