Thoreau's Forests Confront Climate Change
2026-05-03 14:00 - 15:00 | First Parish in Concord, 20 Lexington Rd, Concord, Massachusetts, US
Will We Still Have Forests in 50 Years? And Why We Should Care
Dr. William Moomaw, a lead author of the 2007 Nobel Peace Prize winning climate report, will explore the role of forests and other ecosystems in moderating climate change in combination with new technologies and our behaviors. The threats to our forests from climate change and other stresses will be a major theme. The discussion will be moderated by Delia Kaye, Concord’s Natural Resources Director.
William Moomaw is Professor Emeritus and Founding Director of the Center for International Environment and Resource Policy at the Fletcher School at Tufts University, and Distinguished Visiting Scientist at Woodwell Climate Research Center. He received his PhD at MIT in Physical Chemistry. As a member of the chemistry department at Williams College, he directed the Center for Environmental Studies. He served as a Congressional Science Fellow and worked on the legislation that banned CFCs from spray cans and on the 1976 National Forest Management Act.
Professor Moomaw was a 5-time lead author of IPCC Reports addressing the science and technological mitigation of Climate Change. He was elected a Fellow of the American Association for the Advancement of Science for his “Outstanding Contributions to our understanding of climate change and its global impacts and to the work of the Intergovernmental Panel on Climate Change.”
