The following are among the achievements made during the first 3 years of a 5-year project to reconstruct past climatic fluctuations in the Northern Hemisphere from variations in the growth rings of trees 1 Growing international collaboration stimulated by this research effort 2 Development of 127 high-quality tree-ring chronologies from North America and Europe 3 The establishment of the International Tree-Ring Data Bank 4 Evaluation of multivariate techniques for calibration and analysis and 5 The selection of a revised data set for reconstructing North American climate. These results will be used to improve reconstructions of past climate and to expand them to eastern North America and Europe.
