Glaciochemical time series developed from Summit, Greenland, indicate that the chemical composition of the atmosphere was dynamic during the Holocene epoch. Concentrations of sea salt and terrestrial dusts increased in Summit snow during the periods 0 to 600, 2400 to 3100, 5000 to 6100, 7800 to 8800, and more than 11,300 years ago. The most recent increase, and also the most abrupt, coincides with the Little Ice Age. These changes imply that either the north polar vortex expanded or the… 

Holocene climate dynamics in Fennoscandia and the North Atlantic

Set against the high amplitude climatic variations that characterised the Pleistocene, the majority of the Holocene epoch was once considered to be comparatively stable. Indeed, observed post-19th

Palaeo-oceanography: Deepwater variability in the Holocene epoch

Investigation of changes in the carbon-isotope composition of benthic foraminifera throughout the Holocene finds that deep-water production varied on a centennial–millennial timescale, which may hint at a contribution to climate change over this period.

The climate change in our current interglacial period, the Holocene, is relatively muted compared to the larger-scale, rapid climate oscillations during the preceding glacial period.

Holocene climatic instability: A prominent, widespread event 8200 yr ago

The most prominent Holocene climatic event in Greenland ice-core proxies, with approximately half the amplitude of the Younger Dryas, occurred ∼8000 to 8400 yr ago. This Holocene event affected

Little Ice Age clearly recorded in northern Greenland ice cores

Four ice cores drilled in the little investigated area of northern and northeastern Greenland were evaluated for their isotopic (δ18O) and chemical content. From these rather uniform records a stable

Peat record reflecting Holocene climatic change in the Zoigê Plateau and AMS radiocarbon dating

Through the use of reliable AMS dating of high resolution (15–30 years) peat and the establishment of monsoon climate proxies sequence, we have been able to recognize several cold, dry events in the

Abrupt changes in North American climate during early Holocene times

Recent studies of the Greenland ice cores have offered many insights into Holocene climatic dynamics at decadal to century timescales. Despite the abundance of continental records of Holocene

A Quantitative Holocene Climatic Record from Diatoms in Northern Fennoscandia

A diatom-based calibration model for predicting summer temperatures was developed using climatically sensitive subarctic lakes in northern Fennoscandia. The model was applied to a sediment core from

Holocene climate variability in the northern North Atlantic region: A review of terrestrial and marine evidence.

The Holocene epoch, which followed the last major pulse of glaciation (the Younger Dryas) at the end of the last glaciation, encompasses a period before there was any substantial anthropogenic

Holocene warming marked by abrupt onset of longer summers and reduced storm frequency around Greenland

The abrupt climate shifts identified in Greenland ice cores transformed understanding of the climate system. Although primarily studied in the paleoclimate record, abrupt climate change induced by

The Atmosphere During the Younger Dryas

High-resolution, continuous glaciochemical records, newly retrieved from central Greenland, record the chemical composition of the arctic atmosphere at this time, showing that both the onset and termination of the Younger Dryas occurred within 10 to 20 years and that massive, frequent, and short-term changes in atmospheric composition occurred throughout this event.

Glacial-Interglacial Changes in Moisture Sources for Greenland: Influences on the Ice Core Record of Climate

Results from general circulation model experiments suggest that the sources of Greenland precipitation varied with different climate states, allowing dynamic atmospheric mechanisms for influencing the ice core isotope shifts.

Abrupt increase in Greenland snow accumulation at the end of the Younger Dryas event

THE warming at the end of the last glaciation was characterized by a series of abrupt returns to glacial climate, the best-known of which is the Younger Dryas event1. Despite much study of the causes

The ‘flickering switch’ of late Pleistocene climate change

POLAR ice contains a unique record of past climate variations; previous Greenland ice cores have documented relatively warm ‘interstadial’ periods during the last glaciation and short (centuryscale)

RECORDS of the variation in atmospheric methane concentration have been obtained from ice cores for the past 1,000 years and for the period 8,000–220,000 yr BP (refs 1–4), but data for the

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

Carbon-14 production rate variations that are not explainable by geomagnetic changes are thought to be in antiphase with solar activity and as such should be in antiphase with paleotemperature
