An important goal of the U. S. Global Change Program is to quantify the natural rate and range of variability i the climate system. One of the principal sources of paleoclimatic data with annual resolution comes from the analysis of tree ring thickness. From these data it is possible to reconstruct records of past temperature and precipitation for at least the last few centuries, and perhaps up for the last millennium. This renewal proposal, by an established tree-ring laboratory, requests support to continue the production and analysis of paleoclimatic data derived from tree rings. The goal of the project is to quantify the thickness variations in tree rings; relate the variations in thickness to ecological and climatological parameters; develop long-term records of annual variation in climate; and attempt to isolate anthropogenic effects from natural variations in climate. This research is important because it well help to isolate natural variability in the climate system from the effects of fossil fuel burning by man.

美国的一个重要目标。S.全球变革计划是 量化气候变化的自然速率和范围 系统 古气候数据的主要来源之一， 年分辨率来源于树轮厚度分析。 从这些数据中可以重建过去的记录。 至少在过去的几年里， 几个世纪，也许是上个千年。 此续订 一个已建立的树木年轮实验室提出的建议要求 支持继续制作和分析古气候 数据来源于树木年轮。 该项目的目标是 量化树木年轮的厚度变化; 厚度变化对生态和气候 参数;发展长期的年度变化记录， 气候;并试图将人为影响与 气候的自然变化。 这项研究很重要 因为它很好地帮助隔离了 人类燃烧化石燃料的影响。
