Biosphere 2 Fellow
Department of Geosciences and Tree-Ring Research

Jessie Pearl is a paleoclimatologist who is interested in understanding temperature and hurricane variability in the heavily populated northeastern United States. By using paleoclimate data, we can better constrain the possible future climates of the Northeast and better prepare coastal managers and community organizers for increasing storm and temperature severity. A Ph.D. student in the Department of Geosciences and Laboratory of Tree-Ring Research, Jessie uses sediment cores and tree-ring measurements of both live and ‘sub-fossil’ (dead trees that have not fossilized) Atlantic white cedar along the northeastern coastline to precisely date large storm events and reconstruct an annual temperature record for the past 2,000 years. A record of this resolution currently does not exist and will aid in understanding the complex northeastern climate. Before coming to the UA, Jessie worked for the Environmental Protection Agency and the National Park Service, which taught her the significance of appropriately communicating science and the importance of connecting with the natural world.
