Abstract The Last Interglacial period (LIG) was characterized by a long-term Arctic atmospheric warming above the preindustrial level. The LIG thus provides a case study of Arctic feedback mechanisms of the cryosphere-ocean circulation-climate system

Periodic meltwater pulses from the Laurentide-Greenland Ice Sheets during the last deglaciation drove abrupt changes in sea surface temperature and sea ice extent, according to sediment core biomarker proxy records from the Eirik Drift, eastern Labra

Shrinking of the Laurentide Ice Sheet mobilized the underlying rock organic carbon. Together with permafrost carbon release, this may contribute 12 ppm to deglacial CO2 rise, underscoring the impact of cryospheric change on the carbon cycle.

The Beaufort Sea was nearly ice-free during the transition from the last deglacial to the Holocene, a period in which two episodes of high sediment flux suggest major glacial flood events, according to high-resolution multi-proxy biomarker records.

Abstract To evaluate the present sea ice changes in a longer‐term perspective, the knowledge of sea ice variability on preindustrial and geological time scales is essential. For the interpretation of proxy reconstructions it is necessary to underst

Coinciding with global warming, Arctic sea ice has rapidly decreased during the last four decades. Here, using biomarker records, the authors show that permanent sea ice was still present in the central Arctic Ocean during the last interglacial, when

Owing to the hierarchical organization of biology, from genomes over transcriptomes and proteomes down to metabolomes, there is continuous debate about the extent to which data and interpretations derived from one level, e.g. the transcriptome, are i

The response of Arctic sea-ice to rapid climatic change in the past remains uncertain. Here, the authors use biomarkers and microfossils to reconstruct Arctic sea-ice changes over the past 90,000 years, and demonstrate millennial-scale variability.

Despite the importance of Arctic sea-ice in the global climate system, a paucity of pre-Quaternary sedimentary archives limits our understanding of its long-term history. Here, based on ancient sediments revealed by submarine landslides, the authors

The study on the decay of ice sheets in the past provides important insights into the interaction between ice sheet behaviours and ocean characteristics, especially under a sustained warming climate. On the one hand, the ice sheet may affect the ocea
