Population and Climate Change provides the first systematic in-depth treatment of links between two major themes of the twenty-first century: population growth and associated demographic trends such as aging, and climate change. It is written by a multidisciplinary team of authors from the International Institute for Applied Systems Analysis, who integrate both natural science and social science perspectives in a way that is readable by members of both communities. The book will be of primary interest to researchers in the fields of climate change, demography, and economics. It will also be useful to policy-makers and NGOs dealing with issues of population dynamics and climate change, and to teachers and students on courses such as environmental studies, demography, climatology, economics, earth systems science, and international relations.
