Our reconstruction reveals that centennial-scale rapid warming occurred repeatedly following multicentennial cooling trends during the last millennia. These results correlate with different records from the Northern Hemisphere,indicating that the periodic alternation between cool and warm periods on a sub-millennial scale had a subhemispherical influence.","author":null,"citation":"Tan, M.;Liu, T.;Hou, J.;Qin, X.;Zhang, H.;Li, T. 2003.
