HAMPTON, Va. – "Global warming is a real phenomenon," claimed Roger Mann, director for research and advisory services for the Virginia Institute of Marine Science, in a recent Senate Environment and Public Works subcommittee hearing on the topic of global warming and wildlife. "The addition of climate change to the mix of stressors already affecting valued habitats and endangered species will present a major challenge to the future conservation of U.S. ecological resources."

Mann, who is also a professor of marine science for the College of William and Mary, will address the effects of climate changes in a colloquium lecture called "Climate Change Impacts on Natural Resources in Virginia" on Tuesday, Sept. 11, at 2 p.m. in the H. J. E. Reid Conference Center at NASA Langley Research Center. That evening, Mann will speak on the subject again for the general public at 7:30 p.m. at the Virginia Air & Space Center on Settlers Landing Road in Hampton.

Media who wish to interview Mann at a news briefing at 1:15 p.m. Tuesday should contact Emily Sturgill at 864-7022 or at emily.r.sturgill@nasa.gov by noon for credentials and entry to NASA Langley.

Mann has published over 100 peer review research publications, edited 3 books, and was awarded the Chesapeake Bay Commission Tribute to Excellence in 1994. Much of his research concentrates on climate change impacts on natural resources. He has also focused on shellfish stock assessment and ecology, larval ecology and the biology and management of invading and non-native species in new environments.
