Congratulations to Ruth Morgan on the publication of Climate Change and International History: Negotiating Science, Global Change and Environmental Justice (Bloomsbury). This book reveals the ways that climate change emerged and evolved as an international problem, and how states, scientists and non-governmental organizations have engaged in diplomatic efforts to address it. Developing amidst the Cold War, decolonization and a growing transnational environmental consciousness, it asks how this wider historical context has shaped international responses to the greatest threat to humankind to date. Congratulations Ruth!
