本文对三个不同年代的刺果松年轮进行了氢稳定同位素分析。这些树木给出了从8000年前到现在的连续时间序列，表明6800年前存在冰后期气候最佳状态，此后持续降温。这一记录与其他来源的记录（如冰芯、花粉和树线波动）之间的定性一致性表明，这些气候变化是全球性的。这一记录可以作为过去8000年其他气候指标的参考。
Tree rings from three dendrochronologically dated bristlecone pines were analyzed for stable hydrogen isotopic composition. These trees give a continuous time series from 8000 years ago to the present that indicates the presence of a postglacial climate optimum 6800 years ago and a continuous cooling since then. The qualitative agreement between this record and records from other sources, such as ice cores, pollen, and treeline fluctuations, indicates that these climate changes were global. This record can serve as a reference for other climate indicators throughout the past 8000 years.
