	{{w\|Dendrochronology}} is a scientific method of using tree rings to tell the age of a tree and learn about historical climate from features found in each ring. It's based on the fact that trees add a new ring each year, so counting the rings will tell a tree's age in years. Additionally, climate and ecology affect the size and composition of each year's ring, so scientists can use rings to estimate what conditions were like each year. They can cross-compare tree-ring samples from overlapping date ranges, of comparable trees grown and felled at different times, to build up and confirm a useful ring history well beyond that of a single tree.		{{w\|Dendrochronology}} is a scientific method of using tree rings to tell the age of a tree and learn about historical climate from features found in each ring.
