Investigating societal responses toward climate pulsations, this book explores environmental challenges through a timeframe of climate pulsations and response patterns in different civilizations. This "societal-climate-society" approach helps to establish the relationship between climate and civilization.

It argues that history is a collection of repeated decisions toward challenges in different climate cycles. As an application of Darwinian evolutionary theory on human societies, Ellsworth Huntington's theory of climate pulsation is modified and tailored to explain Samuel Huntington's theory of the clash of civilizations, which discloses the invisible hand behind war and peace.
