        Navajo Technical College | Dendroclimatology

        In this video segment adapted from Navajo Technical College, meet Steven Chischilly, a professor of environmental science, and hear about his research on climate change. Listen as he describes how climatic conditions, such as moisture and precipitation, contribute to tree growth rates and the amount of carbon that is stored by a tree in different years. Learn about dendroclimatology -- the study of the relationship between climate and the annual growth rings of trees -- and how he is correlating historical weather station data about the Navajo Nation with growth rings.
