TLDR
The warmest millennia of at least the past 250,000 years occurred during the Last Interglaciation, when global ice volumes were similar to or smaller than today and systematic variations in Earth's orbital parameters aligned to produce a strong positive summer insolation anomaly throughout the Northern Hemisphere as mentioned in this paper.About:

Processes and impacts of Arctic amplification: A research synthesis
Mark C. Serreze,Roger G. Barry +1 more
TL;DR: The past decade has seen substantial advances in understanding Arctic amplification, that trends and variability in surface air temperature tend to be larger in the Arctic region than for the Northern Hemisphere or globe as a whole as discussed by the authors.

TL;DR: The Palaeoclimate Modelling Intercomparison Project (POMIP) as discussed by the authors evaluated model performance against the geologic record of environmental responses to climate changes and provided a unique opportunity to test model performance outside this limited climate range.

Sea-level rise due to polar ice-sheet mass loss during past warm periods
Andrea Dutton,Anders E. Carlson,Antony J. Long,Glenn A. Milne,Peter U. Clark,Robert M. DeConto,Benjamin P. Horton,Stefan Rahmstorf,Maureen E. Raymo +8 more
TL;DR: This work concludes that during recent interglacial periods, small increases in global mean temperature and just a few degrees of polar warming relative to the preindustrial period resulted in ≥6 m of GMSL rise, which is currently not possible to make a precise estimate of peak G MSL during the Pliocene.

TL;DR: A 2.8-million-year record of Arctic climate is developed using a sediment core from a lake in northeastern Russia that was formed more than 3.5 million years ago by a meteorite impact, suggesting strong interhemispheric climate connectivity.

TL;DR: In this article, the history of Arctic sea-ice conditions through the geologic past is investigated using proxy records from the Arctic Ocean floor and from the surrounding coasts, which indicate that sea ice became a feature of the Arctic by 47-Ma, following a pronounced decline in atmospheric pCO2 after the Paleocene-Eocene Thermal Optimum, and consistently covered at least part of the arctic Ocean for no less than the last 13-14 million years.

TL;DR: 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.

TL;DR: 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.

Observational evidence of recent change in the northern high-latitude environment

TL;DR: In this paper, the authors present asynthesis of these observations, and conclude that roughly half of the pronounced recent rise in Northern Hemispherewinter temperatures reflects shifts in atmosphericcirculation. But, such changes are not consistent with anthropogenic forcing and include generally positive phases of the North Atlantic and ArcticOscillations and extratropical responses to the El-NinoSouthern Oscillation.
