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
