This book is an up-to-date guidebook for persons who are unfamiliar with the relevant details but want to know what anthropogenic global warming and its repercussions entail. The first chapter presents background material on the earth's climate system and some of the global warming rejecters' claims and their refutations, including the evidence underlying the reality of anthropogenic global warming. The next chapter examines in detail many of global warming's contemporaneous and deleterious repercussions, while the final one considers some future scenarios and their likely consequences, some of which are from the latest IPCC Reports. It also considers a number of the proposed steps to avoid these consequences, and the problems of implementing them.
