Global Warming: The Hard Science presents a comprehensive, qualitatively rigorous, and critical discussion of the science underlying the global warming issue. The major processes in the climate system needed to understand projected human-induced climatic change are presented in detail. Observational systems used to monitor changes in the climate system and the ways in which the raw data are analyzed in order to produce estimates of current trends are also critically reviewed. It will be an indispensable text for students wanting a comprehensive understanding of the science of global warming, as well as for lecturers and researchers who want to improve their understanding of global warming research outside their own subdiscipline. It is set to become the definitive textbook on the science behind the global warming issue. Global warming is now seen as fundamental to the study of the environment and this text clearly emphasises not only the importance of global warming in the environmental change process, but also introduces students to the science required to analyse these changes accurately.
