The Native Peoples-Native Homelands Climate Change Workshop was held on October 28 through November 01, 1998, as part of a series of workshops being held around the U.S. to improve the understanding of the potential consequences of climate variability and change for the Nation. This workshop was specifically designed by Native Peoples to examine the impacts of climate change and extreme weather variability on Native Peoples and Native Homelands from an indigenous cultural and spiritual perspective and to develop recommendations as well as identify potential response actions. Native Peoples, with our spiritual traditions and long community histories of change, adaptation, and survival in specific regions, are providing a unique contribution to the assessment and understanding of climate change as well as to the development of sustainable economies in this country.
