“…The Tibetan Plateau (TP), one of the Earth's most imposing geomorphic features, is a climatically very important region due to its influence on large-scale atmospheric circulation patterns over Asia, including the summer monsoon over South Asia and the South China Sea (Ding, 1992;Li and Yanai, 1996;Webster et al, 1998). During the past decades, a great number of paleoclimatic records covering the last centuries were derived from ice cores Liu et al, 1998;Thompson et al, 1993Thompson et al, , 2000Thompson et al, , 2003Thompson et al, , 2006aWang et al, 2006;Yao et al, 1997;, tree rings (Bräuning, 1999;Bräuning and Mantwill, 2004;Cook et al, 2003;Zhang et al, 2003a,b;Shao et al, 2005;Fan et al, 2008Fan et al, , 2009Gou et al, 2006Gou et al, , 2008Sheppard et al, 2004;Liu et al, 2006a,b;Esper et al, 2002Esper et al, , 2003aTreydte et al, 2006), lake sediments (Herzschuh et al, 2006;Wu et al, 2001;Zhang et al, 2003a,b;Zhang et al, 2004;Liu et al, 2006a,b;Zhao et al, 2007Zhao et al, , 2008Zhao and Herzschuh, 2009) and glacier fluctuations (Bräuning, 2006;Yang et al, 2007) on the TP and adjacent areas (Yang et al, 2003;Ge et al, 2007;Wang et al, 2007). However, it is difficult to compare the results obtained from different proxy data due to lack of calibration ...…”
