Varve Chronology, Proxy Calibration, and Holocene Climate of Minnesota
… the early- to mid-Holocene postdated the 8.2 ka event at the 95% confidence level of 14C dates, (2) that the two mid-Holocene climatic stages likely resulted from a regional reconfiguration of air masses, and (3) that millennial-scale climatic cycles did not occur in the midwestem United …

Investigating Mexican paleoclimate with precisely dated speleothems
… the northeast Mexican response to the 8.2 ka event and the Younger Dryas. These chapters show that the San Luis Potosí region is vulnerable to droughts under multiple climate mean states, and is subject to drying as Atlantic Meridional Overturning Circulation weakens due to anthropogenic …

Holocene climate and environmental dynamics on the Tristan da Cunha island group, South Atlantic
… temperature is contemporaneous with the 8.2 ka event in the Greenland ice cores and is probably the South Atlantic response to the weaker circulation induced by freshwater forcing in the North Atlantic. Tristan da Cunha was discovered in 1506 AD by Portuguese explorers and their arrival is …

The impact of glaciation and climate change on biogeochemical cycling and landscape development
… of the Dry Lake sediment prior to the 8.2 kyr event revealed average values for percent total organic carbon to be 4% with a range of 0.2% to 15.2%. The average decreased to approximately 2.1% with a range of 0.4% to 5.3% during and after the event. Occluded phosphorus averaged 488 µg/g before …

The palaeolimnological record of regime shifts in lakes in response to climate change
… abrupt ecological change associated with the 8.2 ka cooling event. Using change-point analysis we found two regime shifts in the diatom record: one in response to an abrupt erosion event at c. 8040 cal. yr BP, and another caused by climate warming following the 8.2 ka event. The study demonstrates …
