This project will support a synthesis spanning more than three decades of research, focused on tree-ring analyses of northern forests. The northern forest ecosystems of the great land masses of North America and Eurasia are highly sensitive indicators of the Earth's carbon cycle. Over the past decades, these forests have yielded valuable information on variation in boreal forest growth as well as climatic and environmental change for the past millennium. Two main products will result from this project. First, a comprehensive, widely-accessible monograph that will synthesize this extensive body of tree-ring analysis from northern forests related to global change studies. The monograph will examine the so-called 'divergence effect', which means figuring out how and why tree growth and temperature patterns are not lined up at many northern sites, in recent decades. Documenting the divergence effect is critical for identifying and understanding the implications of future climate change on tree growth. Second, a CD atlas will be produced based on compilation of long-term tree-ring data, descriptions and reconstructions. This CD product will be made available to researchers and students worldwide and will provide important perspectives regarding the state of the science and provide materials for development of school curricula. This synthesis provides insights into the scientific decision-making process and is relevant to policy makers concerned with global change and its impacts.

该项目将支持跨越三十年研究的合成，重点是北部森林的树环分析。 北美和欧亚大陆大地块的北部森林生态系统是地球周期的高度敏感指标。在过去的几十年中，这些森林在过去的千年中产生了有关北方森林生长以及气候变化和环境变化的宝贵信息。该项目将产生两个主要产品。首先，这是一本全面的，广泛的专着，它将综合与全球变化研究相关的北部森林的广泛的树木环分析。 该专着将检查所谓的“分歧效应”，这意味着要弄清楚最近几十年来许多北部地区不排队的树木生长和温度模式。记录差异效应对于识别和理解未来气候变化对树木生长的影响至关重要。 其次，将基于长期树环数据，描述和重建的汇编而生产CD地图集。该CD产品将提供给全球研究人员和学生，并将提供有关科学状况的重要观点，并为学校课程的开发提供材料。 该综合提供了对科学决策过程的见解，并且与有关全球变化及其影响的政策制定者有关。
