During the first half of the 20th century, the astronomer A. Douglass founded the Laboratory of Tree-Ring Research at the University of Arizona.Douglass sought to better understand cycles of sunspot activity and reasoned that changes in solar activity would affect climate patterns on earth, which would subsequently be recorded by tree-ring growth patterns (i.e., sunspots → climate → tree rings).Comparisons with direct temperature measurements back to 1880 show a high correlation with tree growth.However, in high latitude sites, the correlation breaks down after 1960.Dendrochronology is useful for determining the timing of events and rates of change in the environment (most prominently climate) and also in works of art and architecture, such as old panel paintings on wood, buildings, etc.

One erroneous characterization is that scientists have been hiding the divergence problem.

During the latter half of the nineteenth century, the scientific study of tree rings and the application of dendrochronology began.

In 1859, the German-American Jacob Kuechler (1823–1893) used crossdating to examine oaks (Quercus stellata) in order to study the record of climate in western Texas.

In fact, tree-ring divergence has been openly discussed in the peer-reviewed literarure since 1995.

Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed in order to analyze atmospheric conditions during different periods in history.
