Dendrochronologist
Dendrochronology is the scientific discipline that uses tree rings to determine the age and date of past events, including the growth and changes in climate. Dendrochronologists use tree rings to study past climates, environmental changes, and human history. They can determine the age of trees, the climate conditions in which they grew, and even the occurrence of major events such as volcanic eruptions and earthquakes. Dendrochronology is a valuable tool for archaeologists, historians, and climate scientists.
