The book consists of interviews with leading climate scientists. Experts on different aspects of the topic explain their own field and give their opinion on general questions concerning climate change. The interviews cover both fundamental research (climate modeling, global warming, sea level change, melting of the ice caps, natural hazards) and impact assesment (adaption, mitigation, economic impacts and costs of climate change). The goal is to provide the reader with first-hand information on the current state of climate research.
