As National Park Service (NPS) employees are charged with providing interpretation and education, this manual provides them with a training document and resource guide on the subject of global change. An introduction contains excerpts of the Climate Change Action Plan released in October 1993. Section 2 contains six summaries of technical materials on global change. Section 3 consists of materials that specifically address NPS roles in interpretation and global change. Section 4 contains content materials that may be needed to develop a global change communications program. Twenty fact sheets on related topics were included to provide an overview of the many facets of global change. Section 5 consists of sample global change programs and materials. Each program sheet contains a general program idea designed for a variety of different audiences, interpretive techniques, and park resources. All items are adaptable across media and content. Section 6 offers suggestions for the development of a park's own global change program. Section 7 includes a glossary, book, and article bibliography (87 entries) and a listing of resource materials, teaching aids, and audio-visual resources (60 entries). (LZ)
