The Paleoecological Environmental Assessment and Research Lab (PEARL) is a group of about 30 research scientists, post-doctoral fellows, graduate students, and other scientists dedicated to using paleolimnological  and other techniques to provide historical perspectives to environmental change. Such data are required to define natural environmental variability, to generate and test hypotheses, and to evaluate computer models that are now being used for the study of global environmental change.
