TL;DR: A 150-year-long cooling in the early Preboreal, associated with rising Δ14C values, is evident in all records and indicates an ocean ventilation change, and box-model calculations suggest that they all may have been the result of increased freshwater forcing that inhibited the strength of the North Atlantic heat conveyor.

TL;DR: It is shown that DNA and amino acids from buried organisms can be recovered from the basal sections of deep ice cores, enabling reconstructions of past flora and fauna in high-altitude southern Greenland.

TL;DR: 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.

TL;DR: In this article, a new deglaciation chronology for the ice-free parts of Greenland, the continental shelf and eastern Ellesmere Island (Canada) is proposed, based on a new compilation of all published radiocarbon dates from Greenland, and includes crucial new material from southern, northeastern and northwestern Greenland.

TL;DR: In this article, a synthesis of existing literature on Holocene climate change in Arctic Canada and Greenland is presented, showing that the warmest-to-coldest millennium temperature change in the Holocene is 3.0 ± 1.0°C.
