Hu, Feng Sheng Anderson, Thomas F. Jian, Tian 2015-09-28T15:12:30Z 2015-09-28T15:12:30Z 10000-01-01 2005 2005 Despite the numerous Holocene paleoclimatic records from the North American continent, few existing records from the American Midwest have adequate chronological controls, marking it problematic to link regional climatic changes to possible larger-scale forcing. With solid 14C chronologies, the multi-proxy records from SL and WOL revealed (1) that the abrupt transition from 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 States.
