A top priority in climate research is obtaining broad-extent and long-term data to support analyses of historical patterns and trends, and for model development and evaluation. Along with directly measured climate data from the present and recent past, it is important to obtain estimates of long past climate variations spanning multiple centuries and millennia. Dendroclimatic Studies at the North American Tree Line presents an overview of the current state of dendroclimatology, its contributions over the past few decades, and its future potential. The material included is not useful not only to those who generate tree-ring records of past climate-dendroclimatologists, but also to users of their results-climatologists, hydrologists, ecologists and archeologists. In summary, this book: * Sheds light on recent and future climate trends by assessing long term past climatic variations from tree rings * Is a timely coverage of a crucial topic in climate science portraying recent warming trends which are of serious concern today * Features well-reputed scientists highlighting new advanced methodologies to reconstruct past climate change * Models the tree growth environmental response
