Efforts to extract a Greenland ice core with a complete record of the Eemian interglacial (130,000 to 115,000 years ago) have until now been unsuccessful. The response of the Greenland ice sheet to the warmer-than-present climate of the Eemian has thus remained unclear. Here we present the new North Greenland Eemian Ice Drilling (‘NEEM’) ice core and show only a modest ice-sheet response to the strong warming in the early Eemian. We reconstructed the Eemian record from folded ice using globally… 
How warm was Greenland during the last interglacial period
Abstract. The last interglacial period (LIG, ∼ 129–116 thousand years ago) provides the most recent case study of multimillennial polar warming above the preindustrial level and a response of the
10Be climate fingerprints during the Eemian in the NEEM ice core, Greenland
The results show Eemian average 10Be concentrations about 0.7 times lower than in the Holocene which suggests a warmer climate and approximately 65–90% higher precipitation in Northern Greenland compared to today.
Reconstructing the last interglacial at Summit, Greenland: Insights from GISP2
Improved Eemian climate records from central Greenland are presented, reconstructed from the base of the Greenland Ice Sheet Project 2 (GISP2) ice core, and several unexplained discrepancies remain between the inferred and simulated histories of temperature and accumulation rate at GISp2 and NEEM.
A model of the Greenland ice sheet deglaciation
The goal of this thesis is to improve our understanding of the Greenland ice sheet (GrIS) and how it responds to climate change. This was achieved using ice core records to infer elevation changes of
Retreat and Regrowth of the Greenland Ice Sheet During the Last Interglacial as Simulated by the CESM2‐CISM2 Coupled Climate–Ice Sheet Model
During the Last Interglacial, approximately 129 to 116 ka (thousand years ago), the Arctic summer climate was warmer than the present, and the Greenland Ice Sheet retreated to a smaller extent than
Greenland was nearly ice-free for extended periods during the Pleistocene
It is shown that Greenland was deglaciated for extended periods during the Pleistocene epoch (from 2.6 million years ago to 11,700 years ago), based on new measurements of cosmic-ray-produced beryllium and aluminium isotopes in a bedrock core from beneath an ice core near the GIS summit.
Coupled regional climate–ice-sheet simulation shows limited Greenland ice loss during the Eemian
Abstract. During the last interglacial period (Eemian, 130–115 kyr BP) eustatic global sea level likely peaked at > 6 m above the present-day level, but estimates of the contribution of the Greenland
Early Last Interglacial ocean warming drove substantial ice mass loss from Antarctica
A blue-ice record of ice sheet and environmental change from the Weddell Sea Embayment at the periphery of the marine-based West Antarctic Ice Sheet (WAIS), which is underlain by major methane hydrate reserves is reported.
Quantification of the Greenland ice sheet contribution to Last Interglacial sea level rise
During the Last Interglacial period ( 130-115 thousand years ago) the Arctic climate was warmer than to- day, and global mean sea level was probably more than 6.6 m higher. However, there are large
Understanding the fundamentals of the Earth’s climate system during the Quaternary Period (the past ca 2.6 million years) is of imminent interest in light of the reported recent climatic changes. The


Substantial contribution to sea-level rise during the last interglacial from the Greenland ice sheet
It is concluded that the high sea level during the last interglacial period most probably included a large contribution from Greenland meltwater and therefore should not be interpreted as evidence for a significant reduction of the West Antarctic ice sheet.
Comparison of oxygen isotope records from the GISP2 and GRIP Greenland ice cores
RECENT results1,2 from the Greenland Ice-core Project (GRIP) Summit ice core suggest that the climate in Greenland has been remarkably stable during the Holocene, but was extremely unstable for the
High-resolution record of Northern Hemisphere climate extending into the last interglacial period
An undisturbed climate record from a North Greenland ice core, which extends back to 123,000 years before the present, within the last interglacial period, shows a slow decline in temperatures that marked the initiation of the last glacial period.
Melting of Northern Greenland during the last interglaciation
Using simulated climate data from the comprehensive coupled climate model IPSL CM4, we simulate the Greenland ice sheet (GrIS) during the Eemian interglaciation with the three-dimensional ice sheet
Holocene thinning of the Greenland ice sheet
A pronounced Holocene climatic optimum in Greenland coinciding with maximum thinning near the GIS margins is revealed, and state-of-the-art ice sheet models are generally found to be underestimating the extent and changes in GIS elevation and area.
Greenland ice sheet model parameters constrained using simulations of the Eemian Interglacial
Abstract. Using a new approach to force an ice sheet model, we performed an ensemble of simulations of the Greenland Ice Sheet evolution during the last two glacial cycles, with emphasis on the
A new Greenland ice core chronology for the last glacial termination
[1] We present a new common stratigraphic timescale for the North Greenland Ice Core Project (NGRIP) and GRIP ice cores. The timescale covers the period 7.9–14.8 kyr before present and includes the
Ice Volume and Sea Level During the Last Interglacial
Data indicate that global (eustatic) sea level peaked 5.5 to 9 meters above present sea level, requiring smaller ice sheets in both Greenland and Antarctica relative to today and indicating strong sea-level sensitivity to small changes in radiative forcing.
The glacial inception as recorded in the NorthGRIP Greenland ice core: timing, structure and associated abrupt temperature changes
The mechanisms involved in the glacial inception are still poorly constrained due to a lack of high resolution and cross-dated climate records at various locations. Using air isotopic measurements in

Abstract. The Greenland Ice Core Chronology 2005 (GICC05) is a time scale based on annual layer counting of high-resolution records from Greenland ice cores. Whereas the Holocene part of the time
