Knowledge of regional variations in response to abrupt climatic transitions is essential to understanding the climate system and anticipating future changes. Global climate models typically assume that major climatic changes occur synchronously over continental to hemispheric distances. The last major reorganization of the ocean-atmosphere system in the North Atlantic realm took place during the Younger Dryas (YD), an ∼1100 yr cold period at the end of the last glaciation. Within this region…

Warm summers during the Younger Dryas cold reversal
TLDR
The authors show that the concept of a strong North Atlantic Ocean cooling event as major driver is consistent with warm European summers caused by intensified atmospheric blocking and robust physical evidence that atmospheric blocking of cold westerly winds over Fennoscandia is a key mechanism counteracting the cooling impact of an AMOC-slowdown during summer.
Continued meltwater influence on North Atlantic Deep Water instabilities during the early Holocene
The transition into the Holocene marks the last large, orbitally derived climatic event and ultimately led to the onset of modern oceanic conditions. The influence of this climatic change on North
Deep-water circulation changes lead North Atlantic climate during deglaciation
TLDR
A new synchronization of terrestrial, marine, and ice-core records is reported, which allows the first quantitative determination of the response time of North Atlantic climate to changes in high-latitude NADW formation rate during the last deglaciation.
Hydrological change in Southern Europe responding to increasing North Atlantic overturning during Greenland Stadial 1
TLDR
The findings point to the resumption of the Atlantic overturning circulation as the main mechanism behind the hydrological response in Europe during this mid–GS-1 transition and highlight the complex regional signature of GS-1, very distinctive from previous stadial events.
Hydrological and climate changes in southeast Siberia over the last 33 kyr
Abstract Paleoenvironmental and paleoclimate changes in intracontinental Siberia were reconstructed by continuous, high-resolution records (biogenic silica, U, total organic carbon and N, total S,
Lagged atmospheric circulation response in the Black Sea region to Greenland Interstadial 10
TLDR
The results suggest a bipartite climate response in the Black Sea region to the onset of the Greenland Interstadial, characterized by an in-phase decrease in winter severity and lagged shift in atmospheric circulation, explained by a time-transgressive thermal adjustment of the regional ocean interior.

The Younger Dryas is the most well-documented millennial-scale cooling event of the Quaternary, but the mechanisms responsible for its initiation remain elusive. Here we use a recently revised

Coupled ocean and atmospheric changes during Greenland stadial 1 in southwestern Europe
Abstract Paleoclimate reconstructions suggest that the complex variability within the Greenland stadial 1 (GS-1) over western Europe was governed by coupled ocean and atmospheric changes. However,

Ocean lead at the termination of the Younger Dryas cold spell
TLDR

High-Resolution Greenland Ice Core Data Show Abrupt Climate Change Happens in Few Years
TLDR
A northern shift of the Intertropical Convergence Zone could be the trigger of these abrupt shifts of Northern Hemisphere atmospheric circulation, resulting in changes of 2 to 4 kelvin in Greenland moisture source temperature from one year to the next.

TLDR
It is found that the meridional overturning was nearly, or completely, eliminated during the coldest deglacial interval in the North Atlantic region, beginning with the catastrophic iceberg discharge Heinrich event H1, 17,500’yr ago, and declined sharply but briefly into the Younger Dryas cold event, about 12,700 yr ago.
