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.
During the first half of the 20th century, the astronomer A. Douglass founded the Laboratory of Tree-Ring Research at the University of Arizona.
It is also used in radiocarbon dating to calibrate radiocarbon ages.
New growth in trees occurs in a layer of cells near the bark.
The study of the growth of tree rings is known as dendrochronology.
The study of the relationship between climate and tree growth in an effort to reconstruct past climates is known as dendroclimatology.
"Our study doesn't go against anthropogenic global warming in any way," said Robert Wilson, a paleoclimatologist at the University of St.
Andrews in Scotland and a co-author of the study, which appeared July 8 in the journal Nature Climate Change.
