This learning module aims to engage students in problem solving, critical thinking, scientific inquiry, and cooperative learning. The module is appropriate for use in any introductory or intermediate undergraduate course that focuses on human-environment relationships. The module examines the geography of human activities that produce the major greenhouse gases expected to cause global warming. The module teaches students about the basics of the global climate, energy balance, greenhouse effect, and the origins of regional and national emissions of the important greenhouse gases. It explores the many difficult issues involved in formulating and implementing global climate policy. The module concludes with a critical look at the international negotiations to reduce greenhouse gas emissions as required by the "United Nations Framework Convention on Climate Change." The module contains 7 tables, 8 figures, a list of acronyms, a guide, a summary, an overview, a glossary, references for all units, supporting materials, and appendixes (online sources, films, a guide to the UN Framework Convention, and selected readings). It is divided into thematically coherent; each of which consists of background information, teaching suggestions, student worksheets, and the answers expected for each activity. (Author/BT)
