  <Summary>
    <Abstract>This monograph provides a comprehensive synthesis of dendroclimatic
research based on northern old growth sites in the forests of North America and
Eurasia, as conducted by the scientists at the Lamont-Doherty Earth Observatory&apos;s
Tree-Ring Laboratory (TRL-LDEO) of Columbia University over the past four
decades. 
We focus herein mainly on the latitudinal northern treeline, as
well as other locations further south (such as the elevational treeline in Mongolia,
and the Russian Far East) where trees are often sensitive indicators of past
temperature variability. In keeping with the requirements of the &quot;Opportunities
for Promoting Understanding through Synthesis&quot; (OPUS) program of the
National Science Foundation that funded the writing of this monograph, we
emphasize the research conducted by scientists at the TRL-LDEO. However, we
place these TRL-LDEO Northern Archive studies in the context of the broader field of Northern Hemispheric dendroclimatology, conducted by numerous other researchers and
colleagues who have provided valuable and important insights into this topic over
the years.
