World leaders have made a forceful statement that climate change is the greatest challenge facing humanity in the 21st century. However, little progress has been made in implementing policies to address climate change.

This book helps us rethink the climate change problem, the risks we are facing and how we can respond to these challenges. Understanding the deep uncertainty surrounding the climate change problem helps us to better assess the risks. This book shows how uncertainty and disagreement can be part of the decision-making process. It provides a road map for formulating pragmatic solutions. *Climate Uncertainty and Risk* is essential reading for those concerned about the environment, professionals dealing with climate change and our national leaders.
