ENSO variability has been suggested to be linked to \r\nmillennial-scale oscillations in North Atlantic climate during \r\nthat time, but the proposals disagree on whether increased \r\nfrequency of El Niño events, the warm phase of ENSO, was linked \r\nto North Atlantic warm or cold periods. Here we present a \r\nhigh-resolution record of surface moisture, based on the degree \r\nof peat humification and the ratio of sedges to grass, from \r\nnorthern Queensland, Australia, covering the past 45,000 yr. \r\nWe observe millennial-scale dry periods, indicating periods \r\nof frequent El Niño events (summer precipitation declines \r\nin El Niño years in northeastern Australia). We find that \r\nthese dry periods are correlated to the Dansgaard-Oeschger\r\nevents - millennial-scale warm events in the North Atlantic\r\nclimate record - although no direct atmospheric connection\r\nfrom the North Atlantic to our site can be invoked. \r\nAdditionally, we find climatic cycles at a semiprecessional \r\ntimescale (~11,900 yr). We suggest that climate variations \r\nin the tropical Pacific Ocean on millennial as well as orbital \r\ntimescales, which determined precipitation in northeastern \r\nAustralia, also exerted an influence on North Atlantic climate \r\nthrough atmospheric and oceanic teleconnections.\r\n","author":null,"citation":"Turney, C.S.M., A.P.
