Tree Rings: Counting the Years of Global Warming

This video describes the role that dendrochronology plays in understanding climate change, especially changes to high elevation environments at an upper tree line. Dendrochronologists from the Big Sky Institute sample living and dead trees, describe how correlations between trees are made, and explain how tree cores record climate changes.

Teaching Tips

This video could be used in a variety of curricula unit of study including climate, plants and forests, forest ecosystems, etc.

Because it shows a female lead researcher and male graduate students collecting in the field and bringing the cores back to the lab to analyze them, it allows students to go beyond just looking at paper copies of tree ring patterns.
