A radiocarbon chronology shows that piedmont glacier lobes in the Chilean Andes achieved maxima during the last glaciation at 13,900 to 14,890, 21,000, 23,060, 26,940, 29,600, and ≥33,500 carbon-14 years before present (14C yr B.P.) in a cold and wet Subantarctic Parkland environment. The last glaciation ended with massive collapse of ice lobes close to 14,00014C yr B.P., accompanied by an influx of North Patagonian Rain Forest species. In the Southern Alps of New Zealand, additional glacial… 

Radiocarbon chronology of the last glacial maximum and its termination in northwestern Patagonia

Interhemispheric synchrony of Late-glacial climatic instability as recorded in proglacial Lake Mascardi, Argentina

Several high-resolution continental records have been reported recently in sites in South America, but the extent to which climatic variations were synchronous between the northern and southern

Interhemispheric linkage of paleoclimate during the last glaciation

Combined glacial geologic and palynologic data from the southern Lake District, Seno Reloncavi, and Isla Grande de Chiloe in middle latitudes (40°35’–42°25’S) of the Southern Hemisphere Andes suggest

Climatic inferences from glacial and palaeoecological evidence at the last glacial termination, southern South America

There is uncertainty about the interhemispheric timing of climatic changes during the last glacial-interglacial transition. Different hypotheses, relying on different lines of evidence, point

Interhemispheric climate links revealed by a late-glacial cooling episode in southern Chile

Pollen records from three sites in the Lake District of southern Chile are reported, from which it is inferred conditions similar to modern climate between about 13 and 12.2 14C kyr before present (bp), followed by cooling events at about 12.3 and 11.4‬C‬kyr, supporting the idea that interhemispheric linkage through the atmosphere was the primary control on climate during the last deglaciation.

Evidence for massive discharges of icebergs into the North Atlantic ocean during the last glacial period

SEDIMENTS in the North Atlantic ocean contain a series of layers that are rich in ice-rafted debris and unusually poor in foraminifera1. Here we present evidence that the most recent six of these

Irregular glacial interstadials recorded in a new Greenland ice core

THE Greenland ice sheet offers the most favourable conditions in the Northern Hemisphere for obtaining high-resolution continuous time series of climate-related parameters. Profiles of 18O/<16O ratio

Late Glacial Stage and Holocene Tropical Ice Core Records from Huascar�n, Peru

Two ice cores from the col of Huascar�n in the north-central Andes of Peru contain a paleoclimatic history extending well into the Wisconsinan (W�rm) Glacial Stage and include evidence of the Younger Dryas cool phase, implying that a strong warming has dominated the last two centuries.

Correlations between climate records from North Atlantic sediments and Greenland ice

OXYGEN isotope measurements in Greenland ice demonstrate that a series of rapid warm-cold oscillations—called Dansgaard–Oeschger events—punctuated the last glaciation1. Here we present records of sea

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

The abrupt termination of the Younger Dryas climate event

PREVIOUS studies on two deep Greenland ice cores have shown that a long series of climate oscillations characterized the late Weichselian glaciation in the North Atlantic region1, and that the last
