Journal ArticleDOI
TL;DR: In this paper, the emergence of low-frequency, high-amplitude, quasi-periodic (∼100-kyr) glacial variability during the middle Pleistocene in the absence of any significant change in orbital forcing indicates a fundamental change internal to the climate system.

Journal ArticleDOI
TL;DR: This article employed an extended set of observations of the pre-glacial and postglacial history of sea-level rise at the island of Barbados, together with a refined model of continental deglaciation and an accurate methodology for the prediction of post glacial sea level change.

848 citations


Journal ArticleDOI
TL;DR: The late-Quaternary climate history of monsoonal Central Asia was inferred from 75 palaeoclimatic records which provide information about moisture conditions in the last 50-ka (or part of this period).

712 citations


Journal ArticleDOI
TL;DR: The Greenland Ice Core Chronology 2005, GICC05, is extended back to 42 ka b2k (before 2000 AD), i.e. to the end of Greenland Stadial 11.5 years as mentioned in this paper.

Journal ArticleDOI

453 citations


Journal ArticleDOI
TL;DR: Magnetic susceptibility and grain size records from two continuous red-clay and loess-palaeosol sequences on the Chinese Loess Plateau have been generated to investigate the evolution and variability of the East Asian monsoon during the late Pliocene and Pleistocene.

Journal ArticleDOI
TL;DR: In this article, the authors discuss all the key radiocarbon-dated samples used to establish regional trends in relative sea-level on the eastern coast of Brazil and conclude that there is widespread evidence for a progressive decline, possibly with uneven rates, of relative sea level since the end of the mid-Holocene sea level maximum (PMT) above present sea level and a subsequent fall to the present time.

Journal ArticleDOI
TL;DR: A new Greenland Ice Core Chronology (GICC05) based on multi-parameter counting of annual layers has been obtained for the last 42 ka as mentioned in this paper, which is generally in good long-term agreement with the existing Greenland ice core chronologies and with the Hulu Cave record, but on shorter time scales there are significant discrepancies.

410 citations


Journal ArticleDOI
TL;DR: In this paper, a new marine-terrestrial correlation is proposed to examine the long-term behavior of individual taxa and vegetation trends within the context of global climate changes, in terms of orbital and suborbital variability.

382 citations


Journal ArticleDOI
TL;DR: In this article, a modelled response of the quartz OSL signal to irradiation and illumination (both in the laboratory and under natural conditions) was used to test the accuracy of various published statistical age-models.

Journal ArticleDOI
TL;DR: An expanded Cariaco Basin 14C chronology is tied to 230Th-dated Hulu Cave speleothem records in order to provide detailed marine-based 14C calibration for the past 50,000 years.

Journal ArticleDOI
TL;DR: Luminescence dating comprises a collection of numerical age techniques that are among the most significant chronological tools currently used in Quaternary research as discussed by the authors, including thermoluminecence dating of heated minerals to the development of optical dating methods for sunlightexposed sediments.

Journal ArticleDOI
TL;DR: In this paper, a high-resolution oxygen isotopic record of cave calcite from Caverna Botuvera (27°13′S, 49°09′W), southern Brazil, which covers most of the last 36 thousand years (ka), with an average resolution of a few to several decades was determined with 46 U/Th ages from two stalagmites.

Journal ArticleDOI
TL;DR: In this article, the authors conducted an extensive and up-to-date review of terrestrial and marine climatic conditions in the Levant and Eastern Mediterranean during the last 25,000 years.

Journal ArticleDOI
TL;DR: The last deglaciation and its climatic events such as the Bolling-Allerod (BA) and the Younger Dryas (YD) have been clearly recorded in the δ 13 C profiles of three stalagmites from caves from Southern France to Northern Tunisia.

Journal ArticleDOI
TL;DR: In this paper, the authors explore a "stacking" and "tuning" approach to the derivation of regional records from peatland climate proxies to test its applicability to non-annually resolved terrestrial records.

Journal ArticleDOI
TL;DR: In this article, high-resolution pollen and charcoal records from three sites in lowland Switzerland and southern Germany allow testing the human vs. fire-disturbance hypotheses by means of time-series analysis.

Journal ArticleDOI
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.

Journal ArticleDOI
TL;DR: In this paper, a conceptual model for the deglaciation of Atlantic Canada in which a role is played by ice streams is presented, where a major ice stream in the Laurentian Channel, secondary streams in the Bay of Fundy/Gulf of Maine, Trinity Trough and Notre Dame Channel, and lesser ice streams elsewhere.

Journal ArticleDOI
TL;DR: In this paper, the authors present reservoir ages from dating 21 whales collected 1860-1901 and recalculating dates of 23 molluscs collected 1857-1926.

Journal ArticleDOI
TL;DR: Improvements in taxonomic resolution of fossil midges, expansion of modern training sets, use of air temperature data derived from meteorological stations rather than surface-water temperature data, and Bayesian statistical approaches have lead to improvements in the performance of chironomid-temperature transfer functions.

Journal ArticleDOI
TL;DR: Tunnel valleys are large, elongate and irregular depressions cut beneath the margin of former ice sheets as mentioned in this paper, and they play a substantial role for the entire hydraulic system beneath ice sheets and thus also for ice sheet behaviour.

Journal ArticleDOI
TL;DR: In this paper, the authors review the more recent studies on zoobenthos responses to changes in lake productivity and to altered sublittoral and hypolimnetic oxygen conditions, as reflected from subfossil midge assemblages and palaeostratigraphies.

Journal ArticleDOI
TL;DR: In this article, a new approach to U/Th coral dating was proposed that corrects for open-system behavior and produces a sea-level curve of sufficient resolution to confidently correlate with SPECMAP over the last 240,000 years, permitting a reassessment of both this critical chronology and a central tenet of climate change theory.

Journal ArticleDOI
TL;DR: Wang et al. as mentioned in this paper investigated the distribution of phytolith assemblages in China from surface soil samples at 243 sites along significant ecological and climatic gradients to develop transfer functions for quantitative reconstruction of palaeoenvironment.

Journal ArticleDOI
TL;DR: In this paper, the authors compare proxy evidence with climate model simulations in which the thermohaline ocean circulation is perturbed by a freshwater pulse into the Labrador Sea, showing a cooling that is mainly concentrated in the North Atlantic region.

Journal ArticleDOI
TL;DR: In this article, a detailed faunal, isotopic, and lithic marine records provide new insight into the stability and climate progression of the last interglacial period, Marine Isotope Stage (MIS) 5, which peaked approximately 125,000 years ago.

Journal ArticleDOI
TL;DR: In this article, a detailed record of the Galapagos region over the last 135 thousand years (kyr) was reconstructed from G. ruber Mg/Ca from core TR163-22, which revealed a detailed (250-450 year resolution) climate history of the region.

Journal ArticleDOI
TL;DR: A trachytic volcanic ash layer is widely distributed across southwestern Russia, where it is found both in well-characterised archaeological contexts close to the Don River (the Paleolithic sites of Kostenki-Borschevo (51.4°N, 39.0°E), and in undisturbed geological contexts.

Journal ArticleDOI
TL;DR: For example, in this paper, the authors used a thin layer of glaciomarine sediments resting sharply on till to detect iceberg deformation in the eastern Ross Sea during the last glacial maximum.
