Climate Tree rings are a rainfall record during a year. During a wet year, a tree grows more, and makes the rings wider and light-colored. Years that have cool summer temperatures produce denser wood. This makes the light-colored bands of wood thinner. A researcher can tell what the areaâ€™s climate was like hundreds of years ago by the thickness and density of the tree rings. Trees that grow in the same climate develop matching thick and thin ring patterns. Other Climate Factors Other factors influence tree growth.

By noting the location and the climate influences on the tree, it is used to identify trees grown in similar conditions.[read the rest]
