ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides a careful, comprehensive, detailed, reliable description of the individual and interactive contributions of the group of seven countries, group of twenty countries and United Nations summits and the special climate summits in the global governance of climate change from 2015 to mid-2021. It explains these contributions and results, by considering the impact of causal candidates at all levels of analysis, from that of a changing physical ecosystem and international political system to the individual leaders of the world's most systemically significant countries. The book focuses on the application and improvement of an established, compact causal model, grounded in international relations theory, to guide these tasks. This will assist others in developing, prescribing and implementing immediate, realistic actionable policy solutions to cope with the urgent, existential challenge of climate change, in a world rapidly running out of time.
