Richard Norby, physiological ecologist, to speak on global warming April 24Could trees hold the answer to global warming?
Richard Norby, a physiological ecologist, will explain what he's learned through experiments since 1982 on the responses of trees and forests to elevated atmospheric carbon dioxide. Norby's talk, "Will CO 2 Fertilization Counteract Global Warming? Lessons from Forest FACE Experiments ," will be at 4 p.m., April 24, in Tennessee Tech University's Foster Hall, Room 233.
"Dr. Norby is a pioneer in large-scale manipulative field experiments to study the response of natural ecosystems to increasing concentrations of carbon dioxide in the atmosphere," said Dale Ensor, TTU's Environmental Sciences Ph.D. program director. "The Environmental Sciences Ph.D. program is fortunate to have him speak as part of our Student Colloquium Program."
Norby, a UT-Battelle corporate researcher at Oak Ridge National Laboratory, focuses on tree growth, forest ecology, carbon and nitrogen cycling and global change. He has served as a principal investigator of the Oak Ridge Experiment on CO 2 Enrichment of Sweetgum and the Old-field Community Climate and Atmosphere Manipulation experiment.
Norby holds a bachelor's degree in chemistry from Carleton College and a doctorate in forestry and botany from the University of Wisconsin. He is a member of the American Association for the Advancement of Science, the Science Steering Group for the North American Carbon Program, and environment section editor of New Phytologist.
The presentation coincides with the observance of Earth Day, April 22, which was founded by Sen. Gaylord Nelson to raise environmental awareness in the 1960s. The positive public response to Nelson's efforts led to the national observance of Earth Day.
Norby's presentation, free and open to the public, is sponsored by TTU's environmental sciences doctoral program and the Center for the Management, Utilization and Protection of Water Resources. For more information, contact Environmental Sciences Ph.D. Program Director Dale Ensor at 372-3493.
