Dr. Tim Barnett is a research marine geophysicist in the Climate Research Division of Scripps Institution of Oceanography, University of California, San Diego. His research focuses on the physics of climate change and long-range climate forecasting.

A native of California, Barnett attended Pomona College in Claremont, CA and received a BA in physics and mathematics. He received his PhD in oceanography from Scripps in 1966. Barnett investigates global atmospheric and oceanic conditions and uses computer models to understand global climate fluctuations such as climate prediction (including El Niño forecasting), the effects of land processes on climate change, and the recognition of greenhouse gas signals (such as sea-level rise). He also specializes in the detection of anthropogenic signals associated with global warming.

He received the Sverdrup Gold Medal from the American Meteorological Society in 1993, the highest honor the American Meteorological Society can bestow on an oceanographer. Barnett is a member of the American Geophysical Union and the American Meteorological Society and is the author of more than 230 scientific papers.

Dr. Woodhouse received her Ph.D. degree in Geosciences from the University of Arizona in 1996.

Prior to initiating his work at the University of Washington, Christensen worked on a project for the Swedish International Development Institute (SIDA) researching safe, sustainable, arsenic free drinking water solutions for Bangladesh. This required creation and compilation of extensive GIS analysis of the existing UNICEF and BGS database, as well as managing KTH/SIDA's groundwater chemistry database.

Bradley Udall is Director of Western Water Assessment (WWA) at University of Colorado, one of seven RISA (Regional Integrated Sciences and Assessments) programs funded by the Office of Global Programs at NOAA. These programs are designed to develop partnerships with regional stakeholders and tailor NOAA data products to meet their needs. Lessons learned here are also contributing to NOAA's emerging "National Climate Service," the climate analog to the existing National Weather Service.

WWA was created in 1999 and is a joint effort between CIRES and the Climate Diagnostics Center. Using multidisciplinary teams of experts in climate, water, law, and economics, the Western Water Assessment provides information about natural climate variability and human-caused climate change. This information — usually in the form of climate forecasts and regional vulnerability assessments — is designed to assist water-resource decision makers such as Denver Water. Udall frequently speaks on the issues of climate change and has testified in Congress on potential impacts to water supplies in the West.

David Wegner is an applied scientist specializing in the evaluation of climate change on large landscapes and species in ecosystems likely to be impacted by modified temperature regimes. Previous to working as an independent scientist, he spent over 20 years within the Department of the Interior. This included work with federal agency coordination, natural resource management, endangered species, and western water issues.

Since leaving the Department of the Interior in 1996 Wegner has served as a private consultant and expert on western water, endangered species, river restoration, and adaptive management across the country and internationally. As a recognized environmental expert, he has prepared briefings for the U.S. Senate and House natural resource staffs on environmental issues in the West. He also frequently provides briefings and participates in reviews for Congressional staffs, H. John Heinz Center for the Environment and Economics, and the National Academy of Science in Washington, DC on endangered species, water, dam impacts, and adaptive management issues. His international work includes studies with Russian, Japanese, European, and other Asian scientists on impacts of land and water management, climate change and management of species and their habitats. He is a trustee and science director of Glen Canyon Institute.

Dr. Wade Graham is an environmental writer and historian who has written for The New Yorker, Harper's, The Los Angeles Times, Outside and other publications. He is a trustee of Glen Canyon Institute and editor of Hidden Passage: The Journal of Glen Canyon Institute. He holds a Ph.D. in American history from UCLA. His book on the environmental history of Hawaii, "Braided Waters: Environment, Economy and Community in Molokai, Hawaii" is forthcoming from the University of Hawaii Press. He is currently working on a book for HarperCollins publishers entitled American Eden: From The Thirteen Colonies to the Present, What Our Gardens Tell Us About Who We Are (Pub date 2009).

Dr. Robert Adler is the Associate Dean for Academic Affairs and James I. Farr Chair in Law at the S.J. Quinney College of Law at the University of Utah. He regularly teaches courses in civil procedure and environmental law, and is currently co-designing an interdisciplinary course called "Environmental Law and Engineering," in which law students and environmental engineering graduate students will work together on real-world environmental problems in Utah.

Adler received a B.A. from Johns Hopkins University in 1988, and a J.D. from Georgetown University Law Center in 1980, where he graduated cum laude and served as editor-in-chief of the journal Law and Policy in International Business. He served as assistant counsel to the Pennsylvania Department of Environmental Resources and was active in the Three Mile Island litigation. He was staff attorney and executive director of Trustees for Alaska from 1984 to 1987.

His books include his most recent, Restoring Colorado River Ecosystems: A Troubled Sense of Immensity, as well as Environmental Law: A Conceptual and Pragmatic Approach and The Clean Water Act: Twenty Years Later. In 2002, he was honored with the Pfeifferhorn Conservation Leadership Award, given by a coalition of state environmental organizations in recognition of his efforts to preserve Utah's natural resources.

Katie Lee is well known in the Southwest as a writer-photographer-actress-singer-musician who fights for the preservation of wild and remote places. A native Arizonan, she began her professional career in 1948 as a stage and screen actress. She performed in motion pictures in Hollywood, had running parts on four major NBC radio shows; in the early 50s, and was a pioneer actress on national television. In the mid-50s she left Hollywood to spend 10 years "on the road" as a performer in coffeehouses and bistros throughout the US, Canada and Mexico, singing folksongs to her own guitar. Her early albums of folk music are long out of print, but six more recent CD are still available. She has also released three videos, including Love Song to Glen Canyon. She has also written three books, Sandstone Seduction, Ten Thousand Goddam Cattle and All My Rivers Are Gone.

Lee is one of a handful of women and men who knew the pristine Glen Canyon, making sixteen trips down the river and even named some of the side canyons. For more than a decade she regularly ran, guided, photographed, and explored the Glen; knew the river guides and characters that roamed there; and even named some of its side canyons. The construction of Glen Canyon Dam and drowning of Glen Canyon became the diving force that turned her into an environmental activist and agitator for draining Lake Powell reservoir and restoring Glen Canyon. Katie serves on the Advisory Board of the Glen Canyon Institute.

James Kay's photography has been published in magazines, books, and calendars around the world. He currently serves as a professional advisor to Outdoor Photographer Magazine and his work has been featured in the Nikon Legends Collection. His landscape photographs have been displayed in the Museum of Utah Art & History and The Utah Museum of Natural History, and they are currently displayed in private and corporate collections around the world.

For the last 25 years, Kay's photography has centered on his love of untrammeled wild country. He writes: "One of the main goals in my landscape work is to capture images of the natural world as it appears to me in the field so others may appreciate the beauty of these last wild places. In my own small way, I hope to inspire people to work together to insure that we pass along a healthy life-supporting planet to future generations." As a part of these ongoing efforts, his photographs were recently displayed in the U.S. Capitol Rotunda.

Bill Wolverton is a lifelong hiker and backpacker, starting in the Sierra Nevada of his native state of California. He first visited the Escalante River canyons in 1979, and permanently moved to the region in 1986. Since then, he has extensively explored Glen Canyon National Recreation Area, Zion National Park, and Canyonlands National Park. He has also worked to eradicate invasive and non-native Russian olive and tamarisk from the area's canyons.

Beginning in 1979, Wolverton has visited the Escalante River canyons every year except one. During these trips, he has systematically photo-documented the remote Glen Canyon backcountry. His early photos recorded the status of Glen Canyon while flooded under Lake Powell reservoir at its highest water levels. In recent years, his photos have detailed the emergence and remarkable recovery of these canyons as reservoir levels have declined. This extraordinary photographic time series is providing a unique baseline for measuring the scope, degree, and rate of recovery that is occurring in the Glen Canyon ecosystem.

Martin Litton is a legendary Grand Canyon river runner and a longtime environmental activist, best known as a staunch opponent of the construction of Glen Canyon Dam and other dams on the Colorado River. He first floated the Colorado River through the Grand Canyon in 1955, at the time becoming only the 185th person known to have made the trip down the river first pioneered by John Wesley Powell. He continues to make occasional river trips, and is the oldest person to have operated his own boat through Grand Canyon (in 2004 at age 87).

Litton was a close friend of David Brower, Edward Abbey, and other major figures in the conservation movement. Brower first recruited him in 1952 for a campaign to oppose the construction of two dams in Dinosaur National Monument. This began a longtime association with the Sierra Club and a lifelong opposition to dam building on the Colorado River. A 1964 river trip led by Litton, which included Brower, and Francois Leydet, led to the publication of the 1964 book authored by Leydet, Time and the River Flowing, which helped to galvanize opposition to the proposed dams within the Grand Canyon.

Between 1954 and 1968, Litton was the travel editor for Sunset Magazine. In 1960, Sunset ran a cover story entitled "The Redwood Country," which is credited with launching a campaign that eventually led to the establishment of Redwood National Park. Most recently, he has campaigned to halt logging in California's Giant Sequoia National Monument and to drain Lake Powell and restore Glen Canyon. Litton served on the Board of Directors of the Sierra Club from 1964 to 1973. He currently serves on the Advisory Committee of the Southern Utah Wilderness Alliance and on the Honorary Board of Directors of the Glen Canyon Institute.

Dr. Barbara Brower is a professor of geography at Portland State University in Oregon. Her interests lie in biogeography, cultural ecology in the regions of High Asia, Nepal and the Western United States. She also has a strong interest in mountains, wildland resource conservation and policy, and the environmental movement. She is the editor of the journal Himalaya, which seeks to promote understanding and appreciation of the region through the publication and support of original research and other important work; and to review scholarship, research, and other information of interest to Himalayanists. She attended the University of California at Berkeley, where she received a Ph.D. and an M.A. in geography and a B.A. in anthropology.

Brower is the author of Sherpa of Khumbu: People, Livestock, and Landscape (Studies in Social Ecology and Environmental History) and editor (with Barbara Rose Johnston) of Disappearing Peoples?: Indigenous Groups and Ethnic Minorities in South and Central Asia. She serves on the board of Earth Island Institute.

Kenneth Brower is a writer specializing in wildlife and ecological issues as well as a longtime environmental activist. He is a frequent contributor to The Atlantic Monthly and National Geographic, and a winner of the John Burrows Association Award for Outstanding Natural History Essay. He is the author of more than a dozen books, including The Starship and the Canoe, A Song for Satawal, Wake of the Whale, and Freeing Keiko. Brower serves on the board of Earth Island Institute and The David Brower Center.

Congressman George Miller has served California's 7th District (East Bay of San Francisco) in the U.S. Congress since 1975. He is one of the most effective and consistent champions of the nation's wildlife and wild lands. His conservation achievements include providing key leadership in protecting the integrity of the Endangered Species Act and advancing congressional actions to increase funding for federal lands conservation.

Miller was Chairman of the House Natural Resources Committee from 1991 to 1994 and ranking member until 2000. He continues to play a key role on that committee, which oversees the environment, energy, and public lands. Miller has authored many laws concerning energy policy, forest management, and timber reform. In 1997 and again in 2002, he introduced strong Endangered Species Act reauthorization legislation called The Endangered Species Recovery Act. In 2005, he developed and offered a responsible alternative to a bill introduced by Rep. Pombo that would have seriously undermined the Endangered Species Act.

Born and raised in California, Miller also secured important protections for that state's land and water. In 1992, he successfully passed and enacted the historic California water reform law known as the Central Valley Project Improvement Act. He also co-authored the visionary 1994 California Desert Protection Act with Senator Dianne Feinstein, which protected dozens of national park and wilderness areas encompassing more than 7 million acres.

For decades, Miller has worked to ensure that Congress fulfills its promise to provide substantial annual funding for federal land acquisition programs, and he has sponsored and championed several bills on this subject. He was elected by his colleagues in January 2007 as Chairman of the House Education and Labor Committee, a panel he has served on since first coming to Congress and on which he has served as the Senior Democrat since 2001. At the beginning of the 110th Congress, he was also appointed by Speaker Nancy Pelosi to serve as chairman of the House Democratic Policy Committee, a position he has held at her request since 2003. In that role, he is responsible for helping Democrats to develop and articulate a wide range of policies of benefit to all Americans.

Miller graduated from Diablo Valley Community College and San Francisco State University and earned his law degree from the University of California, Davis, School of Law.
