When was the first tree ring climate record established?
Quick Answer
Tree rings were first systematically used for climate dating in the early 20th century, especially from the 1900s onward.
The Full Story
Tree-ring analysis, or dendrochronology, became a scientific dating tool in the early 1900s. A key pioneer was Andrew Ellicott Douglass, who used ring patterns to link tree growth with climate cycles. By comparing patterns across living and dead trees, scientists could build long climate records. This method became one of the most important tools for studying past droughts, temperature shifts, and environmental change.
