Introduction

Abstract

This chapter provides an introduction to this book, briefly outlining each chapter. It discusses the challenges posed by climate-related hazards, highlights critical components or early warning systems, mentions examples of current early warning systems, and describes emerging areas of development. Suggestions on ways to improve warning communication, and encourage early action, are provided. The potential utility of broader risk management approaches and flexible and forward decision-making are also mentioned. This chapter concludes that great progress has been made in early warning systems. But sustained efforts are needed to refine the political, social, and financial mechanisms that support warning systems. Continued improvement is all the more urgent given an ethical responsibility to issue warnings that prevent loss of life and property and help build adaptive capacity.
