This is a thought-provoking graduate-level textbook on global problems of environmental policy and economics, global warming, reforestation, and the greenhouse effect. It goes beyond the traditional climate and biology discussions associated with the climate change debate by including broader, interdisciplinary issues concerning, for example, alternatives to business as usual policies, economics and the green market, and future climatic and human change. Part I deals with the global commons, policy, and economics. Part II covers climatic and human change, including global warming, the greenhouse effect, reforestation, and energy policy. Part III discusses economic and greenhouse perceptions, freeing the green market, and the what the future holds. Includes bibliographic references and index.
