How do tree rings record changes in weather and climate?
Quick Answer
Trees usually add one ring per year, and the ring width and density can reflect wet, dry, warm or cold growing seasons.
The Full Story
Tree-ring science, or dendrochronology, uses the yearly growth layers in wood to study past environmental conditions. In many climates, wider rings indicate better growing conditions, while narrow rings can reflect drought, cold or stress. Scientists can match ring patterns from living trees and ancient wood to build long climate records. Tree rings have helped reconstruct droughts, volcanic cooling and other climate events over centuries to millennia.
