    Climatic fluctuations recorded in Antarctica and Greenland during the last deglaciation (18-10 ka) differ markedly in their timing. It remains controversial whether local climate fluctuations recorded in southern mid-latitudes relate primarily to northern or southern polar records. We present...

    The potential usefulness of ring width and maximum density of Picea glehnii Mast. as indicators of climatic changes in northern Hokkaido,Japan, was evaluated. We selected three growth sites of P. glehnii that were characterized by different soils, namely, Spodic Udipsamments, Hemic Medifibrists,...
