The 8.2 ka cooling event was an abrupt, widespread climate instability. There is general consensus that the episode was likely initiated by a catastrophic outflow of proglacial Lakes Agassiz and Ojibway through the Hudson Strait, with subsequent disruption of the Atlantic meridional overturning circulation. However, the total discharge and flux during the 8.2 ka event remain uncertain. We compute the sea-level signature, or “fingerprint,” associated with the drainage of Lakes Agassiz and…

Investigating the impact of Lake Agassiz drainage routes on the 8.2 ka cold event with a climate model

Abstract. The 8.2 ka event is the most prominent abrupt climate change in the Holocene and is often believed to result from catastrophic drainage of proglacial lakes Agassiz and Ojibway (LAO) that

New estimates of the magnitude of the sea-level jump during the 8.2 ka event

We analyzed sediment cores from coastal Lake Izabal, Guatemala, to infer Holocene biogeochemical changes in the lake. At ca. 8370 calibrated yr B.P. (cal. yr B.P.), marine waters entered the lake,

Timing and magnitude of the sea-level jump preluding the 8200 yr event

Evidence from terrestrial, glacial, and global climate model reconstructions suggests that a sea-level jump caused by meltwater release was associated with the triggering of the 8.2 ka cooling event.

The incised valley of Baffin Bay, Texas: a tale of two climates

Baffin Bay, Texas is the flooded Last Glacial Maximum incised valley of the Los Olmos, San Fernando and Petronila Creeks along the north‐western Gulf of Mexico. Cores up to 17 m in length and

Breaching of Mustang Island in response to the 8.2 ka sea-level event and impact on Corpus Christi Bay, Gulf of Mexico: Implications for future coastal change

The results from an investigation of the coupled Mustang Island–Corpus Christi Bay complex, Gulf of Mexico, shows that the island was eliminated as an effective salinity barrier between 8.86 and 8.17



Tracking the sea‐level signature of the 8.2 ka cooling event: New constraints from the Mississippi Delta

The ever increasing need for accurate predictions of global environmental change under greenhouse conditions has sparked immense interest in an abrupt, century‐scale cooling around 8200 years ago,

Rapid sea level rise and ice sheet response to 8,200-year climate event

The largest abrupt climatic reversal of the Holocene interglacial, the cooling event 8.6–8.2 thousand years ago (ka), was probably caused by catastrophic release of glacial Lake Agassiz‐Ojibway,

Forcing of the cold event of 8,200 years ago by catastrophic drainage of Laurentide lakes

The sensitivity of oceanic thermohaline circulation to freshwater perturbations is a critical issue for understanding abrupt climate change. Abrupt climate fluctuations that occurred during both

The 8.2 kyr BP event simulated by a Global Atmosphere—Sea‐Ice—Ocean Model

Seven freshwater perturbation experiments were performed with a global atmosphere—sea‐ice—ocean model to study the mechanism behind the 8.2 kyr BP Holocene cooling event. These experiments differed

Simulation of the response to an abrupt cooling event across the Northern Hemisphere using a coupled general circulation model and atmosphere-only experiments provide compelling evidence that changes in ocean circulation played a major role in this abrupt climate change event.
