A monograph written by a group of professional dendrochronologists and graduate students, this book synthesizes research on tree growth in northern old-growth forest sites in Eurasia and North America. These very slow-growing trees in remote landscapes have traditionally provided reliable annual tree ring growth records. These are used to establish the exact dates of historical and archeological events, and to determine weather and climate in past eras and measure climate change over time. This book focuses on the latter topic. It responds to scientific questions about whether and how global climate change is affecting tree growth in these areas, and how in turn those changes might affect the science of dendrochronology. Trees at the northern limits of growth are sampled, and so are locations further south, such as Mongolia and far eastern Russia, where the tree line depends on altitude. Black and white and color maps and tables are provided, as is an extensive bibliography. Annotation ©2014 Ringgold, Inc., Portland, OR (protoview.com)
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

I enjoyed the short format, and would support the production of further AGU OPUS themed syntheses, but would respectfully suggest that the programme reviews the format to permit a wider scope for general themes and greater detail for more specialist topics. (The Holocene, 1 February 2015)
