对生长在东喜马拉雅地区树线上的致密冷杉的年轮分析表明，夏末(7-9月)的温度对该树的生长起着重要的控制作用。根据这一环宽数据重建了这三个月的年平均气温。这一记录可以追溯到公元1507年；然而，公元1757年之前的数据是有问题的，因为它们只基于一个样本。重建的过去237年的温度序列显示出年到多年的波动，不时地出现冷暖周期。整个过程中最热和最冷的10年分别出现在1978-1987年(+0.25摄氏度)和1801-1810(-0.31摄氏度)。
Tree-ring analysis from Abies densa growing at the treeline in the Eastern Himalayan region reveals that temperature during late summer (July-September) plays a significant role in controlling the growth of this tree. Mean temperature of each year for these three months has been reconstructed based on this ring-width data. This record goes back to A.D. 1507; however data prior to A.D. 1757 are questionable because they are based on only one sample. The reconstructed temperature series for the last 237 yr shows annual to multiyear fluctuations punctuated with cool and warm periods. The warmest and coolest 10-yr periods of the entire span occurred in 1978-1987 (+0.25degreesC) and 1801-1810 (-0.31degreesC), respectively.
