Sinopse
Each ring on a tree stump can mark a complete cycle of the seasons, dating back thousands of years. University of Arizona researcher Charlotte Pearson talks about how trees have recorded events through time, from floods to solar storms. She will give a talk on the subject next Wednesday at the College of Science free lecture series.
