Charts the course and causes of UN, G7 and G20 governance of climate change through the crucial period of 2015-2021, providing a careful, comprehensive and reliable description of the individual and interactive contributions of the G7, G20 and UN summits and analyses their results. The authors explain these contributions and results by considering the impacts of causal candidates, such as a changing physical ecosystem and international political system and the actions of individual leaders of the world's most systemically significant countries.

Climate change control has risen to the top of the international agenda. Failed efforts, centred in the United Nations, to allocate responsibility have resulted in a challenge now reaching crisis stage. John J. Kirton and Ella Kokotsis analyse the generation and effectiveness of four decades of intergovernmental regimes for controlling global climate change. Informed by international relations theories and critical of the prevailing UN approach, Kirton and Kokotsis trace the global governance of climate change from its 1970s origins to the present and demonstrate the effectiveness of the plurilateral summit alternative grounded in the G7/8 and the G20. Topics covered include: - G7/8 and UN competition and convergence on governing climate change - Kyoto obligations and the post-Kyoto regime - The role of the G7/8 and G20 in generating a regime beyond Kyoto - Projections of and prescriptions for an effective global climate change control regime for the twenty-first century. This topical book synthesizes a rich array of empirical data, including new interview and documentary material about G7/8 and G20 governance of climate change, and makes a valuable contribution to understanding the dynamics of governing climate change. It will appeal to scholars, researchers, and policy makers interested in the dynamics behind governance processes within the intergovernmental realm.
