This book is for readers who are frustrated with the chronically slow action by governments and other actors to stem climate-changing pollution and to deal effectively with its manifestations and future consequences. Much as a physician diagnosing a patient with multiple diseases would aim to treat the most life-threatening pathologies before moving on to lesser problems, the focus here is on the most important pathologies of climate governance – those that are vital to understanding and identifying therapies and remedies. (Much of climate governance up to now has focused on many significant but lesser pathologies.) A few of the remedies for climate governance that are proposed here may at first appear to border on the idealistic. However, they are practicable because they are premised on promoting the interests of the actors involved. They will not harm the interests of states or their citizens; to the contrary, they will promote their long-term security and well-being. Promotion of self-interest is not the only thing that motivates governments, corporations or individuals to do the right thing. But it helps.
