On the basis of synchronization of three carbon-14 (14C)-dated lacustrine sequences from Sweden with tree ring and ice core records, the absolute age of the Younger Dryas-Preboreal climatic shift was determined to be 11,450 to 11,390 ± 80 years before the present. 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. This cooling is similar to earlier deglacial coolings, and box-model calculations…

Abrupt climate oscillations during the last deglaciation in central north america
TLDR
Evidence from stable isotopes and a variety of proxies from two Ontario lakes demonstrate that many of the late glacial-to-early Holocene events that are well known from the North Atlantic seaboard also occurred in central North America, implying that climatic forcing acted in the same manner in both regions and that atmospheric circulation played an important role in the propagation of these events.
Synchronous radiocarbon and climate shifts during the last deglaciation.
TLDR
Reconstructed changes in atmospheric carbon-14 are larger than previously thought, with the largest change occurring simultaneously with the sudden climatic cooling of the Younger Dryas event.
COLD REVERSAL ON KODIAK ISLAND, ALASKA, CORRELATED WITH THE EUROPEAN YOUNGER DRYAS BY USING VARIATIONS OF ATMOSPHERIC 14C CONTENT
High-resolution AMS (accelerator-mass-spectrometer) radiocarbon dating was performed on late-glacial macrofossils in lake sediments from Kodiak Island, Alaska, and on shells in marine sediments from…
Freshwater Forcing of Abrupt Climate Change During the Last Glaciation
TLDR
It is found that periods of increased freshwater flow to the North Atlantic occurred at the same time as reductions in the formation of North Atlantic Deep Water, thus providing a mechanism for observed climate variability that may be generally characteristic of times of intermediate global ice volume.
The last termination in the central South Atlantic
Lake sediments and peat deposits from two basins on Nightingale Island (37 degrees S), in the Tristan da Cunha archipelago, South Atlantic, have been analyzed. The studies were focused on the time…
A regional 8200 cal. yr BP cooling event in northwest Europe, induced by final stages of the Laurentide ice-sheet deglaciation?
The most notable change in δ18O in Greenland ice cores during the Holocene occurs at 8200 cal. yr BP. Here we present a new high-resolution marine record from the northern North Sea, along with…
Three amphi-Atlantic century-scale cold events during the Bølling-Allerød warm period
Oxygen isotope composition of carbonates in the sediments of Crawford Lake, southern Canada, reveals multiple climatic events during the last deglaciation, including the Bolling warming,…
Deglacial surface circulation changes in the northeastern Atlantic: Temperature and salinity records off NW Scotland on a century scale
Sea surface temperature and salinity estimates reconstructed from a core collected on the Barra Fan, northwest Scotland (56°43′N, 09°19′W; water depth 1320 m), show a series of rapid oscillations…
Modelling the concentration of atmospheric CO2 during the Younger Dryas climate event
Abstract The Younger Dryas (YD, dated between 12.7–11.6 ky BP in the GRIP ice core, Central Greenland) is a distinct cold period in the North Atlantic region during the last deglaciation. A popular,…
Deglacial abrupt climate change in the Atlantic Warm Pool: A Gulf of Mexico perspective
[1] During the last deglaciation, Greenland ice core and North Atlantic sediment records exhibit multiple abrupt climate events including the Younger Dryas cold episode (12.9–11.7 ka). However,…

The Atmosphere During the Younger Dryas
TLDR
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.

Reduced meltwater outflow from the Laurentide ice margin during the Younger Dryas
THE cause of the Younger Dryas cold event, which interrupted the last deglaciation, is still a matter of debate1. A prevalent hypothesis, proposed by Broecker et al.2 is that the abrupt climate…

Routing of meltwater from the Laurentide Ice Sheet during the Younger Dryas cold episode
