This project was funded by the U.S. Geological Survey under the National Research Program, National Climate Change and Wildlife Science Center, the Climate Change Program, the Climate and Land Use Research and Development Program and the Northern Rockies Science Center. Additional funding was provided by the U.S. Fish and Wildlife Service through the Great Northern Land Conservation Cooperative and the Bureau of Land Management Rapid Ecosystem Assessment program. Our project would not have been possible without the very high level of computing support that was provided by the Environmental Computing Center of the College of Oceanic and Atmospheric Sciences, Oregon State University. We thank the Max Planck Institute for Meteorology, Hamburg, Germany, and the NOAA Geophysical Fluid Dynamics Laboratory, Princeton, NJ, for providing GCM history datasets. Over the course of this project, many colleagues and collaborators provided valuable feedback on documentation, design of the web applications and quality control of the datasets. We are grateful for their input, suggestions, and criticisms.
