The SAGE Handbook of Environmental Change is an extensive survey of the interdisciplinary science of environmental change that examines the historic importance and future development of the field over two volumes. With over 40 chapters, the books situate key arguments and debates by examining a retrospective audit of the discipline, its changing nature and diversity of approaches, key theoretical paradigms, its resonances between sub-fields and other disciplines, and its relationships to theory, research and practice. Global in its coverage, scientific and theoretical in its approach, the books bring together an international set of respected editors and contributors to provide an exciting, timely addition to the literature on climate change.
