The authors write that "during portions of the Last Glacial stage, the climate of the high-latitude North Atlantic region was characterized by rapid transitions from cold stadial conditions to warm interstadial conditions," and they say that "these stadial and interstadial events were particularly well developed between about 60 and 20 kaBP [thousand years before present], when they had an average pacing of about 1500 years (e.g. Dansgaard et al., 1993; NGRIP, 2004) and attained nearly two-thirds of the full glacial-interglacial amplitude," noting that "millennial-scale climate variability during the Last Glacial period also is evident in many other locations worldwide (Voelker, 2002), including the tropical oceans (e.g. Arz et al., 1998; Peterson et al., 2000; Stott et al., 2002; Jennerjahn et al., 2004), as well as in the monsoon domains of Asia, East Africa, and Australia (e.g. Schulz et al., 1998; Wang et al., 2001; Altabet et al., 2002; Burns et al., 2003; Turney et al., 2004; Brown et al., 2007)."
