Marni Koopman, Climate Change Scientist

MarniKoopman2015c cropMarni brings communities the science they need to make informed decisions and walks them through a process that results in climate change strategies that are integrated across both natural and human communities. Marni has also worked on developing climate-informed conservation blueprints for the Klamath-Siskiyou ecoregion and the Colorado Plateau. Marni joined the ClimateWise team after completing postdoctoral research with the Forest Service’s Rocky Mountain Research Station. That research investigated the effects of climate change on wildlife and wildlife habitat by working with a team to model climate stress and assess the level of state planning for climate change in the State Wildlife Action Plans. Marni has expertise in climate change effects on wildlife, ornithology, metapopulation ecology, conservation genetics, and invasive species.

Marni holds a B.A. in Environmental Studies from the University of California at Santa Barbara, a M.S. in Wildland Resource Science from the University of California at Berkeley, and a Ph.D. in Ecology from the University of Wyoming.

Tonya Graham, Executive Director

TonyaGraham 2016 crop

Tonya is the Executive Director of the Geos Institute and the Director of its ClimateWise Initiative, serving as the lead for ClimateWise projects. She has taken a lead role in developing the concept of Whole Community Resilience, which takes a holistic approach to addressing climate change impacts and develops solutions that are both ecologically sound and socially equitable. She and her ClimateWise team help community leaders understand likely future conditions, determine vulnerabilities, and develop strategies to address them that care for both people and nature.

In 2019, she and her ClimateWise team launched Climate Ready Communities, an “assisted do-it-yourself" climate resilience planning program that provides affordable assistance to small, mid-sized, and/or under-resourced communities nationwide. She is a co-author of A Practical Guide to Building Climate Resilience, a free, step-by-step planning guide which serves as the foundation for the Climate Ready Communities program.

As a member of the ClimateWise team, Tonya has helped communities adapt to changing climate conditions in Oregon, California, Montana, Alaska, Texas, Kentucky, Colorado, and Ontario, Canada. In 2012 she co-organized with the Kresge Foundation the first national gathering of adaptation practitioners: The Practitioners Workshop on Climate Change Adaptation: Integrated Strategies for Human and Natural Communities. She has developed climate adaptation curricula for the Association of Climate Change Officers.

Tonya served on the Project Advisory Committee for Community-Based Adaptation in the United States: Understanding How and Why Communities are Taking Action. She is a member of the American Society of Adaptation Professionals where she has led working groups to develop climate adaptation program guidance for Congress and incoming administrations. She formerly served as the Treasurer for the Nonprofit Association of Oregon. Tonya holds a B.S. in Biophysical Environmental Studies from Northland College and a M.A. in Community Development from Goddard College.
