dendrochronology
Tree-ring time analysis
Dendrochronology is the scientific method of dating events and environmental changes by analyzing tree rings.
Each ring represents one year of growth, with width varying according to climate conditions.
Researchers use these patterns to date wooden artifacts, reconstruct past climates, and verify radiocarbon dating: Dendrochronology confirmed the beam was cut in 1587.
