The chronology shows a distinct interannual (3 to 5 years) band of enhanced variability suggestive of El Niņo-Southern Oscillation (ENSO) teleconnections into North America during the late Pleistocene, when the Laurentide ice sheet was near its maximum extent and climatic boundary conditions were different than those of today. This interannual variability largely disappears by the young end of the 4000-year chronology, with only the highest frequency components (roughly 3-year period) persisting. This record provides evidence of ENSO-like climate variability during near-peak glacial conditions.","author":null,"citation":"Rittenour, T.M.. 2000.
