Abstract

We began this journey of discovery of decadal climate variability (DCV) impacts on society in the Prologue (Chapter 1) with glimpses of the horrors created by decadal hydrologic cycles (DHCs) in many countries since the fifteenth century CE. These glimpses were followed by an introduction to the water and food challenges the world faces today and is likely to face in the future. The purpose of this book was then described as reviewing the multicentury history of research on natural DCV and attempts to predict it, and reviewing the substantial amount of evidence of DCV impacts on society, largely associated with multiyear to decadal droughts. It was also mentioned that there is a growing need to review the available information and to carry out new research using climate and impacts data. Thus, the purpose of the book is to bring DHCs and their worldwide impacts to the attention of climate and impacts scientists, stakeholders, policymakers, students, and the general public. The book is also meant to be a very useful and important companion to published books, papers, and reports on societal impacts of anthropogenic climate change. The specific purpose of this book is to bring to light natural DHCs and their impacts on human civilization via impacts on water supply, agriculture and other sources of food, transportation and other societal infrastructures, hydroelectricity generation (HEG), economies, sociopolitical conditions, and human conflicts. This chapter summarizes the highlights of DCV impacts and proposes a path forward. Highlights of this book are reviewed in Section 8.2; the significance and importance of the results and conclusions for water, food, and energy securities are described in Section 8.3; then, the outline of a proposed path to bring benefits of DCV and impacts research to the society is described in Section 8.4; and closing remarks are presented in Section 8.5.
